Well the dream begins. I'm embarking on the building of a 914 project. Here is the candidate. Bought a roller from LA area. Looks like its not going to be too much rust. Firsts thing will be to strip it. Taking front fenders and rear quarters off. Then sending to Cal Blast for media blasting. I look forward to the knowledge that I can gain from fellow enthusiasts. Plan on taking a lot of pics Stay tuned......

Welcome aboard!
Good luck!
Cool!! Where are you in SoCal?
Come to the G&R swap meet. Lots of stuff there you will absolutely need. Forget the roll cage. (Unsafe in a street car). Go with the Sheridan body.
and Elliot, wasn't there a Cage in Zonker? Personally I felt a lot safer with a Cage in my car. It was padded
Generally cages are unsafe in street cars because you don't wear a helmet on the street. Since the 914 is so small, it's likely in an accident you will bump your head on the roll cage. In that event, the cage always wins.
Ok, you got my attention.......which twin cam V8? Which 6 speed? Oh, and yes, where in SoCal?

The only place you need to be on the 21st of April.
I have most of the car stripped. Making a rotisserie. As soon as rotisserie is completed I plan on media blasting. Looked into media blasting with pressure washer and crushed glass. Looks like that is the way I will be going. I'll post pictures as soon as I complete the rotisserie.
I can personally recommend the Sheridan body.
[/quote]Yep that is what I'm going with. I'll see you at the G&R swap meet. Are you bringing your 914 with the Sheridan kit??
Well here are some more pictures of the progress. We have removed everything inch of wire, grommet, tubing, cable. All we need now is the suspension. Building rotiserrie before i take suspension off. My trusty helper is my son. We are enjoying this project immensely.
Good job so far. Keep it up!
Take good care of that Harness! Your gonna need it when you restore it
Thank you for the suggestion. Also with respect to the harness, I'm going to have to do a diet on it as I won't be using any of the engine fuel controls. I'm also going to need some grommets as I found it impossible to remove the harness through the rear firewall without removing the large rubber elbow. Also there were some relays underneath the passenger seats that were completely rusted out. I could not remove them without cutting them out. I will be needing a factory manual to see exactly what those relays are for.
I'm also planning on removing the center tunnel and making my own. This can serve various purposes: it makes it easier to re install the wiring harness, the fuel lines, the drive by wire throttle, the hydraulic clutch line, and it gives me the opportunity to install the shifter at the proper height. Also, I have been toying with the idea of bringing a cold air inlet from the front of the car to the rear via this center tunnel. Obviously the cold air/ram tunnel would be separate from the other cables. I could remove the existing fuel tank and buy a cell that fits into the spare tire well. It would be a direct ram of cold air into the cold air box! Also the center tunnel would be taller and much stiffer than the low profile one that it came with. This would add additional stiffness to the frame. The Sheridan front certainly has some real estate in the front for various ports to accomplish this. What do you guys think?
keep it up! a lot of work ahead, but it will be worth it!
Well it has been a while but I have been collecting "stuff" so that I can start and not have to stop too often. I purchased a 2000 996 C4 that was involved in a fire. I am able to use the full suspension, Brembo big reds, jic coil overs, radiators, ac condensors, power steering, power brakes, transmission, axles, pedal assembly. I am purchasing steel flares this week and then I will be able to start work. I will be posting pictures of the German piece of coal donor.
It is going to be a 916 like you haven't seen yet. Top is coming off, steel speedster humps, lowered floor, lowered glass and raked back. Steel cage/frame. I'm wanting to modify the 996 aftermarket front bumper to work with the 914 front an 916 front flares. I'm also removing the front square pop up lights. The real surprise is what I have planned for the rear fender and quarter panel. More to come.
Sounds like a good project... funny, one just sold on ebay (not flared though). If you look you can see the radiator behind the seat even, that's new on a v8 car.

You need that harness up to the 14pin connector at the relay board. The relay board is history.
George, Thank you....I know what you mean. Hopefully that will not be the case here. I almost have everything that I need to get going so its not about not having the parts.

Well here is the rotisserie that I made. I took the best ideas from all of the different ones and made my own. I am satisfied with the way the rotisserie came out. I'm now waiting for my wet sandblasting kit from Power Eagle. They are on back order and will be available at end of June. For now I will just pick up the recycled glass and wait.
Attached thumbnail(s)
Looking forward to this. Damn nice rotisserie. John Deere green from Tractor Supply?
Well since I have to wait until my sand blast kit shows up, I'm taking the front and rear suspension off the 996 to mock up on the 914. Looks like the front will be easy. The rear will require a tube frame. That's OK though since I am planning to tube the rear. I'm planning to pressure wash the suspension this weekend and mock it up on the rotisserie with the car upside down.
Attached thumbnail(s)
Wow, a ton of adjustment (and adjusters!) on those coil overs.
Im not sure which body kit you are looking for but this guy might have a NOS setup for you. He's in Fresno
Neat project.
For mounting the suspension, what are you using for a datum or reference plane to make sure the a-arms are not tilted too far forward or back? Any part of the suspension that is supposed to be parallel with the floor pan?
Damn Bubba, your in my backyard. PM me your address. I'll send you mine. I'd love to "visit" your project while I await my engine seal kit. Kent
And here is the front suspension. I'll be power washing it Saturday morning and then mocking it up on the 914.

I went to Rudy's Saturday to check out his project and to meet a local fellow teener. He has a nice 2 year project and 5 son's for helpers. That's a good start. Here is a pic of the "suspension" donor car.
And here is what burned it down. The Stereo or should I say Stereo installer. This is why you don't let the idiots at oil change centers/stereo shops touch your car. Check out the grommets. Oh, wait a minute. There aren't any.
I took a crappy pic here but this is the stereo's main ground block. I has 4 places for bolts to attach to the body. Can you see that is it is held on by one sheet rock screw that isn't even fully pulled down. So in essence, no friggin ground. And judging from that #4 positive cable I'm guessing it was north of 200w.
Rudy's '74 in a shell state
Rudy cleaning the new suspension
The top of that rollbar must be 2" above the drivers helmet, UNLESS that height would interfere with the operation or fit of the OEM top. In that case the driver's helmet must be below a straightedge bridging between the top of the windshield header and the top of the rollbar over the driver's head(the "broomstick test").
So keep your top on
Well I started to analyze the frame and found that the front windshield bar (the one in red) will need to be upsized. I wasn't expecting that. Also, I wasn't expecting to stiffen the longs (n14 to n13) but after today's, result, looks like it's a must to stiffen the longs even with a roll cage.
Sweet! You don't see too many people doing FEA iterations on chassis.
What software package is that? Almost looks like Ansys APDL or maybe more like Grape? You're modeling with beam elements or trusses? Can you glue a shell element floor on to better match reality? In one of the racecars I worked on laminating a thin carbon shear panel on the floors increased stiffness by 25-30% (experimentally verified via twist test too).
I think you're seeing artificially high loads in N43A because of the huge open box in the cockpit. If you add triangulation near the doors and closer the floor I bet you'll move some of that load path (if my visual FEA makes any sense haha).
Your loading seems a little weird. Why load the lower arms so highly in the vertical direction? They shouldn't see all that much vertical force since it's really all desisted by the spring/damper unit. Why not model the suspension in as an infinitely stiff member and then load with bump, lateral, and longitudinal forces? Then you wouldn't have to draw a free body diagram to figure out point loads.
With actual loading N36B might be more heavily loaded than you think (and in some combined weird bending/buckling mode so it probably needs a big safety factor). If you're doing frame stiffness twisting it (via moment about the front suspension nodes with the back fixed) seems more widely accepted than loading one side. There is a good SAE paper on it, I might be able to find it somewhere.
Sorry if you know all that stuff already. I'm not a mechanics guy by any means but I've spent a bunch of time doing chassis design/analysis for some tube frame racecars and a Lotus.
Are you going to model the suspension?
If so check out GrabCAD, I got the CV joints and center section from there (I modeled the rest)
I am making it out of 4x4 tubing. The tubing has much tighter mill tolerances than hot rolled I-beams. Also square tubing is much better than an I-beam in torsion. To make it out of an I-beam I would have to have it blanchard ground. I'm going with 4x4x3/16 frame with six 4x4x3/16 legs. All cross braced with 4 casters and 6 leveling screws. I'll tack weld on the ground enough so that I can raise and assemble. Then I will level all six legs with my survey equipment. Once leveled I will continue welding all seams a little at a time and from opposing corners so that the table does not warp. Then I will finish in that same Hunter Green as the rotisserie. That small chassis table looks like it's awesome for small projects though.
Thank You JD. I appreciate your excellent input.
2g Lateral Load at rear yields a 1/16" lateral deflection
3g Couple at rear yields a 0.114 vertical deflection
3g Couple at front yields a 0.10" vertical deflection
2g Lateral in front yields a WHOPPING 0.70" lateral defelction. This is the worst case. It makes sense too in that the hole where the engine is allows this deflection. I'll have to fix that somehow. I have to wait until the motor is in to add a removable cross brace or just live with it. We will see.
I'm feeling pretty good about this chassis .
That did it. Since the lower frame is flush with the bottom pan of the car. I can bolt on a plate along the bottom and it totally fixed the flex. The flex now is 0.1" as opposed to 0.7"! I like the way you think. The bottom plate will also blend into a rear diffuser. I am planning on exiting my exhaust above the rear bumper line.
With regard to weight it will add about 150 lbs. However, the front and rear hood, and the front and rear bumpers will be fiberglass. I'm going with about 600 HP so the extra weight will not be a distraction.
It uses thick tubing for the main hoops and thinner everywhere I can.
Well the material came in for the the chassis table.
These are the 2x2's that I will use for the webs
These are the 4x4's that I will use for the table platform and legs
Here are the casters
I also picked up some samples of Fine, Medium and Coarse recycled glass for the wet sandblasting. I'll try each to see which works better. Planning on blasting the suspension clean as well. I'll probably be using the fine for the aluminum blasting. I know guys use glass beads for aluminum but that is for delicate surfaces. The suspension is hardly a delicate surface so we will see how it pans out.
Hey Rudy, I almost stopped by today but then I thought I should first ask if your around during the day. I might still be cleaning my engine Saturday. If I do finish cleaning it by then I'll start bolting the engine back together. I'll let you know when that begins.
That's a lot of metal there. But then again your connected in the welding biz, right?
No more connections. We used to be in the industry 30 years ago. Now the only connection you need is the green kind. Damn steel is crazy expensive. The material was around $1,200 I'm usually in the office, so if you're by the area come on by.
I see what you mean but just think how much better this car will be than stock. Or even those that only are able to reinforce the longs. I think I'll be all right.
So your not planning on gutting the chassis and putting this tube frame under it? Because that what it sounded like.
No I'm not gutting the entire chassis but I am removing quite a bit from the rear. It will not have the rear strut towers, transmission mounts, engine support, rear suspension attachment points, rear lower trunk sheet metal and engine sheet metal wrap around.
Well I've had to take a break to prepare for my son's wedding. I've taken little windows of time and worked on the chassis table thoug. It's almost complete just need to add the webs for the trusses and it's ready to mount the 996 on it first. I'm going to compile xyz coordinates for all of the suspension pick up points on the 996 and then transfer those coordinates onto the 914. That way I will keep the same suspension geometry that the factory had. I'll also be doing a twist test on the 996 and on the 914 pre-tube chassis and post tube-chassis. It will be interesting to note how much better the 914 chassis will be. I'll be taking all of the measurements with a laser plummet and a laser distance measure....stay tuned.

Looks like your moving along well. I did a 914 with 993 suspension a long time ago with an LS6 and G50-52. I had the rotisserie and set up and a welding table For the suspension set up. With no room to store the stuff I got rid of it and now I have a new 914 project starting and was planning on making all the stuff again. As you know it is a huge investment and a lot of work. How about right after you get your chassis set up and of the table you do mine and recover some of the money you have in all this effort? I am just down the road in San Diego. Also here is another thread that you may have seen but its always good to see what others have going and see how they went about things.
http://www.914world.com/bbs2/index.php?showtopic=219539&st=0
Looking good so far and I will be following the progress. And here is a shot of my 914
CSDIILIGAF hey that 914 you did with the 993 suspension looks killer. Let's talk about using my rotisserie and frame table. I'm thinking that I can just rent it out to you for an extended period of time. That way your cost will be a fraction of the cost to make and I get a little back for my investment. PM me and give me your contact information I'm sure I can learn from someone who's done it already. Glad to have you commenting.
JD74914 Instead of using the solid shock idea, which is a cool idea by the way, I was thinking of just setting the car up on 3 jack stands on the frame table, clamping them down and loading the wheel that doesn't have the jack stand under it. What do you think? Is there a better way? And yes I would like to test the twist under various conditions. We're just going to geek out and have fun with the numbers as well as the final product.
Does anyone have a good idea as to how to set up a jackstand with some form of a clamp to attach to bottom of longs? Taking all good suggestions. Bad ones will be ridiculed . Just kidding of course but yeah let me know how you'v e done it or saw someone else do it. BTW no Mo-Clamps those are North of $200 each.
I'm thinking of welding these to the end of a 2x2 post and using them instead of a jack stand. They are cheap and will do the job.
Attached image(s)
Weld a block of steel on one side, and tap for 2 3/8" bolts, add another on the others side and pinch the seem. Add knurling if you want between the jaws. Stands will need to be able to move as this design is not self centering.
Our weld C clamps to the to of the jack stands.
Or weld a set of nuts to steel plates, weld steel plates under the rockers, bolt them to the fixture and grind them off once done.
Put wooden blocks under the rockers, drill holes through the rockers , wooden blocks, and fixture, use all thread, bolt it down.
I am guessing this is to do twist testing.
I would weld three legs down, and not use jack stands, as you will have to strap the car down anyways
Use weldable trailer rings onto the logs, put what ever you want under it, ratchet it down with welded rings on your fixture.
Trailer rings can be found that are rated for 18,000 of force per ring, and cost about 12.50 per ring plus shipping. Then some big straps, or chain. Or just load binders.
914FORME I like your idea about the trailer rings. Yes that will be necessary to be able to hold the car down for the twist test. I'm going to hold down into concrete with a wedge anchor. I do believe that the clamps that I have are rated for 750lbs. I'm going to give them a shot and see what happens.
Well look at what came it today. The parts look to be first rate. Everything is USA made with the exception of a wand piece that is made in Germany. The company told me that they stand by their product and that if I'm not happy with the results that they will take it back. We will see. Supposedly they were able to do 1 sf per 1 min and 15 secs. Not bad at all.

Well chassis table is complete. I measured it with a survey grade level and it is straight to 1/64th or 15 thousands of an inch. Now I can start about with actually working on the 914 rather than building all of the infrastructure (Rotisserie, Chassis Table, Sand Blast Cabinet). I guess I could have done it on the concrete floor and then have a twisted frame. But I couldn't live with myself. Rather, I'm doing it this way though because I just can't do this not knowing if my work is straight. However I have 3 weddings to attend in the next 2 months so my weekends are going to be used up in nonsense cause you know where I would rather be.
The order of work will be as follows.
First load 996 and measure and do a twist test.
second wet sand blast 914 on rotisserie
repair rust and epoxy primer
fourth put 914 on chassis table and do baseline twist test then start building tube chassis

Wow. That's a sweet piece of work.
Thanks bud.
Your table is awesome BTW! I'm super jealous!
JD74914 your responses are always so on the spot and I really do appreciate them. It is what makes these forums. With respect to the twist test incorporating the compliance in the bushings, tie rods, etc., I agree wholeheartedly. However, what I am trying to do is to get a chassis stiffness so that I know how to set up the springs. My current 996 suspension needs new bushings and ball joints, so checking it in this fashion will be counterproductive for my purposes. As you may already know, a rule of thumb is that if your suspension stiffness is more than 10% of the chassis stiffness, then a portion of the chassis will be flexing and absorbing the loads instead of it going into the springs and dampeners. This condition will give a horrible ride and will cause premature cracks in the chassis. I suspect that this happens quite often when people put a really stiff spring on a stock 914 chassis. As would be my case if I just used the springs off of a car that weighs 3274 lbs and placed them in a car that weighs 2100 lbs.
The chassis torsional stiffness that I will check will be:
1) The baseline existing 914;
2) The 914 with the longs stiffened;
3) The 914 with the steel roll cage;
4) The 996 in stock form (oh oh).
My intent is to help other teener's so that they can see if stiffening the longs truly works. And if so, how well? It will be very interesting to me and to others, I suspect.
I've been reading that a typical torsional stiffness for a sports car is somewhere between 10000 and 20000 ft-lbs/degree. Also, F1 cars are much higher than 20,000 ft-lbs/degree.
I hope to load the 996 on the chassis table this weekend. Them I'm off camping to Sequoia so I won't be updating for about one week.
BTW I really did like the way the chassis table turned out. It's nice to know that what you are basing everything off of is straight and true.
Well the 996 is up on the chassis table. I was surprised to find that it had a twist of 1" in the frame. Wow I wonder how this thing handled? I wonder how it got that twist? I don't see evidence of a major wreck?
Attached thumbnail(s)
Heat?
Could be...that's a lot of twist. Check that German engineering on the radiator setup . Every square inch used and you'd never know with the panels on.
76-914 That has to be it. The fire was centered at the left rear corner and that's where the twist is. And here I am asking the stupid questions to the obvious answer.
Chris H. Yes I love the way they did it. Interesting to note that they are set up to exhaust UNDER THE CAR. I figured out a way to use all three in my design. I want the front trunk to be completely useful.
Bet the twist was from when the fire hose quenched the fire; the sudden temperature change probably sucked it in like you would use a torch and rag to suck in a body panel.
The mystery twist has been discovered. Note to self make sure all jack stands are set to the same height. Frame is straight. This is great news since I need to measure the suspension cradle points on the 996 to transfer them to the 914.
cwpeden Yes thanks for the heads up.
jd74914 i'm wondering how much benefit it would be to use the Engman and then add a strip of 1/8" flat stock on the top and bottom flange. That would add quite a bit more to the moment of inertia. The section modulus would be much better than the metal along the sides of the stiffener kit. I suspect that the Engman kit gives more rotational stiffness than bending stiffness though. We will see.
Well I finished measuring the 996 suspension cradle points. Here is how I did it.
First I laser plummet the bolt
Then I transfer that mark to the ground floor like this
Then I measure horizontally like this
Then I measure vertically like this
I also measure all of the diagonals and there you have it. All of the measurements needed to transfer to the 914.
Next step is twist test on 996. I'm out for a week camping so that will have to wait.
Have fun. Looking forward to your next update!
OK back on it. I'm out one week and I can't even find my project on the boards. It was soemthing like 6 pages deep. Anyway, got back from Sequoia and got to twisting the frame on the 996. Here are pictures of my contraption
This is the digital dial indicator that I used
Here is how it triggers the dial indicator
I added 100 lbs (2 -45's and a 10) at a distance of 11.375' This created 1137.5'-lbs of torque. Crazy deflection in the 2x2 but it was still only 50% stressed.
The final number for the convertible 996C4 is......4,568'#/Degree. Seems to be pretty flexible.
Well this weekend member CSDILLIGAF and I will be making the nest for the suspension cradle. He's doing the same project so we'll work on the suspension and frame portions, and who knows what else? It's very helpful to have someone such as him working along side with me. According to my count this will be his 3rd successful Frankenstein transplant. He's the one that did a full 993 suspension on a tube chassis 914. From what I understand his 914 currently races in a very famous race and does very well. I love these 914's they are an incredible platform to work with.
Well here is the suspension nest or fixture as some call it. CSDilligaf came over and we hit it for 8 hours straight. Only stopped of for a carnitas burrito, with rice and beans and all the fixins. Couldn't have done it so fast without CSFilligaf. It was nice to bounce ideas off each other as we put this thing together. Thank you for the input, work and the sweet bushings that you machined. Really pleased with the way it's coming out. It is almost complete as we only need to add the strut tower locations and finish welding a couple of more beads and cross bracing. After this, I can start building the frame for the 914 with this suspension nest centered and elevated within the shell of the 914. Enjoy the pics.

Rudy, I really enjoyed myself working at your place. A little on the hot side and sweat my butt off but we sure hung in there. We got a lot of work done. Cant wait until the next stage of the build.
Subscribed and really enjoying this build....truthfully, I can read some of this but I sure as heck don't understand it...amazing work though and really interesting to see what someone (who clearly has an amazing background) can do with a car in their backyard...speechless actually and thanks for posting. Grant
NS914 Thank you for your kind words. This build would have been very difficult 20 years ago due to knowledge being bottled up in some guru's head and not being able to be shared with no more than those within physical proximity. However, now with the "information superhighway", all we have to do is to research online and fill in our void areas with the specialized knowledge of others. This truly is a great time to be doing projects such as this since one can pull from the collective knowledge of the online community. Trust me we all learn from each other.
Back to the project now. I'm tying in the strut towers today and will have pictures up later. After that....the suspension fixture will be complete. Next step will be to strip the 914 and epoxy primer. I'm using the epoxy primer from a company called SPI. Then pull the 996 of the chassis table and insert 914 onto suspension fixture. Then the fun will start. The rotisserie, the chassis table and suspension fixture was only preparation to work the on the 914.
It will be awesome to see the 914 up on the table and start the whole process of joining the 996 suspension into a 914 chassis. I will make another trip up to help. Be sure to post about how the blasting of the 914 goes.
DAKOTAEWING yes I will be using all SPI material. From the research that I've made they seem to be the HOT TICKET.
CSDILLIGAF yep I'll call you when I get ready to place the 914 in THE NEST . That will be monumental.
Attached are pictures of how I located and tied the strut locations to THE NEST. Man we had to do alot of of the 996 frame to get these locations.
Here is the space age template for the strut towers
Here is the space age marking of said templates
This is what was used to cut
Here it is in place
Well the suspension nest is complete and the 996 can be pulled off and put away.

Very Cool Rudy! Looks great, You've come a long way so far. The fun part is about to begin.
Well the 996 is finally off the nest and no longer needed. Big milestone for me. I'm blasting the 914 this weekend and epoxy primering it.

Well I started to wet blast the 914 and I ran out of sand. I've already used 2000 LBS. I think that I can get away with another 5 bags but I'll just get 10 just in case. Sand is cheap. Here is the video
https://youtu.be/RZ0oQxO59Y8
I'm using the Power Eagle set up. I blew by 2000 lbs of sand and no clog ever. I would dump 300 lbs (3 bags) of sand into a 35 gal trash container. Then I covered to keep the sand dry and clean of debris. I absolutely loved the performance. It wasn't cheap though. It cost $300. However, it did not clog once and I even turned it upside down. I am using a Dewalt 4200 PIS with 4 GPM. Sand is #30 silica sand.
WOW! that Baby sure does the job.
Well I finished epoxy primering the 914. The next step will be to mount onto the chassis table, take some twist measurements and start building the tube chassis. I will be replacing the entire floor. It's just too banged up and rusty to mess with. I will also be removing almost the entire rear half. The entire rear half will be in steel tube and rear half of the body will be bolted to the tube chassis. Found 4 rust areas that I will need to repair. That can wait as they are not in the way of the tube chassis.
Attached thumbnail(s)
Well CSDilligaf came over today and we did the twist testing on the 914. The final numbers are in! The 996 C4 Cabriolet has stiffness of 4,568 '#/Degree. The 914 has a stiffness of 3,326 '#/Degree. So the 996 C4 Cabriolet is 37% stiffer in torsion than the 914. Makes sense, since you'd think that the newer Porsche should be stiffer than the 914, which was built with technology of the 60's. The next step is to place the 914 on the suspension nest and start building the tube frame. I was thinking of stiffening the longs with the Engmann kit, but I'm steering away from that. I will be stiffening the "longs" with a truss system built inside of the longs. That will be the first order of work. I will twist test again at that point and see what improvement we get.

Why not give Engman a call and see if they will give you a kit to test with? I know if I was the manufacturer I would want to know what it did. Im sure he would give you a kit for free.... Most of us run the Engman kit and I for one am curious what real world difference it makes.
Wow that is sad to hear that Engman passed away. My condolences to his family.
As far as trying to see how well the Engman works (inside reinforcing) or Mayeur (outside reinforcing), bring your car over and we will twist it. Have to wait until I'm done with my car though. I'm in Murrieta Ca. It's about 1 hour north of San Diego and about 1:15 hours South of Los Angeles. PM me and we can discuss.
Steel for chassis is coming in tomorrow. Going to build 6 turnbuckle braces to square up driver compartment before I get started. Should have nest in place this week as well. Let the chassis building begin.
Well..........this officially marks the point of no return. Up to this point the 914 could have easily been turned into a restored stock......but now the fork in the road has been reached and I'm taking the "road less traveled". Started to cut up the engine and transmission well. Planning on installing nest tomorrow and will start with "upgrading" the longs first. I couldn't believe how much sand was in the longs. The left long had about a large coffee can of sand in it. I don't know where it could come from since the left did not have any corrosion. On the other hand the right long, the one with the hell hole, that one only had about a up of sand in it? You would expect it to be the other way around. Also, the left long had some fibrous cotton like material inside of it? Anybody have an idea what this is?

So,it's true then,all 914s rust from the inside out,as well as outside in!
They get it from all sides,every direction.
The material found inside is the stuff that absorbs the moisture,inflicting it on the unprotected steel.
The horror.
That cutting and chopping with the plasma is what I've had in mind for the minor stretch,to accommodate the longer engines.
This is getting interesting.Kudos.

Thanks veekry9. After seeing the "surface" rust inside of the longs......I would encourage everyone to stick some of the Eastwood internal frame coating inside. These things rust from the inside out as well as the outside in.

Hey 6freak You're right thank you for the flogging. Point taken. I promise i'll never do it again and post it.
Hey Cracker but yes safety first. Anyway I completed gutting out the rear (phase 1). Phase 2 will be remove the inner fender well weld rear deck lid in place and cut quarter panels and make it tilt back for easy maintenace I also removed the warm air tubes and boy was that tough. They are basically two dryer vent tubes withing each other and insulated with cotton. With the air tubes out I was able to remove all of the sand from the longs. Unbelievable amount of sand. Now I know why they say that you will never get all of the sand out!! In my case I did though. I'm also going to take the opportunity to treat the inside of the longs to that eastwood rust converter. I'm hoping to install suspension jig later today and then start reinforcing the longs with the truss idea.

Well I've been bending and nothching the chassis. I made jig to be able to notch greater than 45 degrees. I have some tubes that need 70 degree bends. I hope to be able to complete the a and b pillar hoops this week. Then it's time to tie the a and b hoops to the front and rear suspension. I was really pleased with the nothching at steep angles. Came out really tight.

Tony
Well I entered the 2017 Build off Challenge. Let's see how it goes.
Well I finally finished bending the A and B pillars. The A pillar was tough! I had to measure, try, measure, try, measure, try......then screw up and try again.
Attached thumbnail(s)
The cage is looking great! I know what you mean about "measure, bend, try again."
I'm sure you're on top of this but the critical factor for me seems to be ensuring the tube doesn't creep as the bend starts. Well, that and being sure I'm bending the correct end of the tube! (Ask me how I know...)
Keep up the great work and lots of pics.
I need a regular fix!
That cage is looking awesome Rudy! Are you using a JD2 bender?
Since you're MIG welding it might not help too much, but it has helped me while TIG welding so I thought I'd share...Apologies in advance if you've heard this before, etc.
If you drill a small hole at each tube junction so the whole cage is one single volume, you can back purge and the quality of the welds is much nicer. Even without purging, the holes let any of the smoke from oil in the tubes move so you don't get any blowouts from pressure buildup while heating and the welds tend to be cleaner.
I just did a roll hoop for a Miata and used 1/2" conduit to form the outer edge of the hoop.. Might be cheaper to grab some conduit than messing up that nice DOM?
Andrew, so you used the conduit to make a test piece? I'm a bit confused by your statement.
Makes perfect sense now.
I was always taught to drill tubes when welding, otherwise you run the risk of making it a pressurized vessel and it may blow out. Molten Metal is not a fun shower.
Do you guys back purge more than just Stainless
No highjacking just good information for those that are following the thread. And yes, I agree no need to backpurge for mig on mild steel. Also, I have never heard of the situation where the tube becomes a pressure vessel? Wow that is amazing and I am having a hard time believing it. One would think that the conditions for it would have to be a one in a million. It's possible but not probable, practically speaking.
While certainly not pressure vessel grade, I've had melt blowout problems with smaller sealed tubes while TIGing. We're talking about 1" tubing of about a foot or little longer length. While not dangerous it's certainly inconvenient.
Well completed trussing the long on the right side. Material is all cut for the left side....that is next. I love the look that it's getting. I also removed the center tunnel. That is going to get some extra special treatment . It will add tremendous stiffness to the chassis.

Whats your thinking behind the placement of those upper bars connecting the front and rear hoops?
Im concerned that they are placed too far inward which could put them directly over the drivers head instead of off to the side. Is there a reason you haven't placed them off to the corners? Theres not a lot of headroom for drivers & passengers as it is in these cars, you might consider putting them as far off to the corners as possible.
Loving the build so far, keep the pictures coming!
That would be wonderful...my drive flange to hub centerline is 2.6" - a 2" increase would be ideal. With a little massaging - I will be able to retrieve about 1". Jealous.

You gonna tell 'em about the other 2" mod or is that classified? Kent
I forgot to add that I tied both of the truss longs with a rear firewall truss. This will stiffen things up a bit.....torsionally speaking

Just in case y'all were wondering.......161 lbs of steel have been added and 124 lbs have been cut out. This comes out to a net add of 37 lbs which is basically the weight of an Engman stiffener. At the end of the day it won't be much heavier than a stock teener.

Does anyone know the weight savings from :
1) Front Fiberglass Hood (21 lbs)
2) rear fiberglass hood (21 lbs)
3) early doors without the heavy crossbar (23.6 lbs)
4) front fiberglass bumper ??
5) rear fiberglass bumper ??
6) lighter battery (10-15 lbs)
that's impressive..
just for giggles, have you ever see this build ??

Rudy - Don't forget the weight of the kerf on each of the cuts made to remove 914 metal... You're doing even better than you think!
Wow, awesome, 26 lb savings with the FG bumpers. Thanks Dane! And what an honor that you think that my work is good. Coming from you that just made my day. By the way, your project was one of the inspirations for my project. I read through every single page and was bummed when you stopped but now am glad to see that you are back on. Thanks for your post.
Well wasn't feeling it this weekend wanted to finish the front but was too tired from surveying a project the day before. Anyway here are some pics of the progress.
Here is the reinforcement from the factory that many use to feed water lines through. Notice the crazy amount of sand inside of these? Also....the corrosion. Put some paint inside of these whenever you can.
Plenty of room to fit in the front "torsinal stiffener enhancer"
Looks like I need to shorten the strut tower.
Smokin some briskett
Can you see "the car" in the background
I wondered about needing to shorten the struts. Yours are already adjustable and may in fact go down enough to fit. I am working on shortening my factory ones first if possible. Hmmm! Brisket looks good!
your looking right at the solution.. Gurney bubble..maybe not..
I'm hungry
I'm not sure if the Gurney bubble would take away from the lines of the 914. But yes it is a solution. However I think that with my coil overs and some machining I may not need the bubbles.
this is what a Gurney bubble looks like in that location.
Attached image(s)
I see, pun intended. Not feeling it though. I wonder what suspension that car has that it would need that??
So I've been thinking and came to the preliminary hunch/suspicion that I can't just cut the strut tower height without changing the instantaneous roll center. This would be horrible and would affect the dynamics of the car. I'm going to do some calculations and figure it out. However I'm thinking that I may be confined to keeping the struts whee I have them now and then figure out how to implement it into the car. Anybody have some input????
Isn't the instantaneous roll center determined by the upper and lower control arm geometry? If that is the case I would think strut tower height is independent of it.
I believe that with the Mc Pherson struts you don't have an upper wishbone. The top of the strut tower is considered the upper wishbone location then you hold a right angle at that location and intersect it with the angle of the lower "a" arm.
see this article
https://balancemotorsport.co.uk/suspension-geometry
It appears that as I lower the strut tower it will raise my roll center. This may not be a bad thing, since depending on where the cg is, it may create a smaller moment arm between the roll center and the center of gravity. If this is the case the car will have less lean in the front end. That may help with creating less understeer. I have to think it through. I have to calc what my cg is up front and then what the 996 roll center is and then what the roll center will be if I lower the strut tower elevation. I need to do some calculations before I make a decision.
I think shortening the length of the strut along its axis will have much less effect than the article shows when the car is simply lowered. By lowering the car the wishbone angle is changed thus effecting the Roll Center. It does not change all that much if you shorten the strut a few inches with out changing the Steering axis inclination. It will change the Instantaneous Center(virtual Point) and I think the rest would still be the same? But I do not have any strut calculation engine so it is just my gut feeling. I just think it has to end up better than the guys who take a 996 and slam it. It will be interesting to see what your calculations come up with.
Shortening the strut will be a step in the positive direction as is will raise the IRC approximately 5/8". Good I wasn't feeling those Gurney bubbles at all.
You're looking right at the solution gurney bubble.....smoker just got it.
Little update, should be able to finish tying in the front struts to the tube chassis. A couple of progress pics.
Here is the strut attachment point cut down to size. I had to move the tower out and forward to account for the strut inclination angle both sideways and forward and backward.
Here is the octagonal shape that I will be using to box int he strut tower
Here is the "strut brace"
Forgot to add this mock up. Test fit of parts before tacking them in. Don't worry the tubes will line up.
Attached thumbnail(s)
You know one thing I would like to plan on is moving the driver over a little so you can square up with the pedals. You already are making your own center console box so its a no brainer at this point. The front end progress looks good. Its a big undertaking for sure but your doing an impressive job. Keep it up
The weather let up a bit and I was able to sneak in some hours into tying the strut towers in. By the way I am really giving it some heavy consideration into changing engines. I'm leaning to a Audi RS4 Stage 3 motor. It will produce 600 HP so its where I want to be. What do you guys think about that motor choice.

A short passage from a book I think I'll write about Rudy:
"It will produce 600 HP so its where I want to be." He said this casually, as though this level of power was commonplace, even easily attained or available without much planning. He was, as everyone already knew, power hungry. He would come to look at his initial 600hp as "a decent starting point". Eventually, he printed t-shirts with this slogan on the front pocket:
If more is good then too much is just enough!
On the back was printed "I'd rather be sideways".
_________________________
Rudy - I vote "Go for it!"
Your build is looking awesome.
You asked Rudy...
I am not a fan of the Audi 4.2 RS4 engine...I saw a nice conversion done into a Boxster race car - very underwhelming. It is low on torque and wasn't competitive either...honestly, I don't care for the sound too. There is a high-price to pay when squeezing big power out of small displacement motors - I know all about them, first hand. Synonymous with hand-grenade.
Remember, you asked!
T
PS: Although both heavy and large - I've thought the GTR TT v-6 would be a nice addition to the 914. Audi have already been done...
PS #2: I'm digging your progress - great job!
4.2 tt rs4 motor? Thats a lot of weight to make that much power.
Its a compact and complicated setup but 600hp is easily made on that setup and it should be extremely torquey.
I think if It were me it would either be the rs4 NA v8 or a S8 4.2 motor for about 360hp to be more economical.
If I wanted to go turbos again with an auto motor I would go 2.7 built with gt28 turbos or KO4 hybrid turbos. That would put a power range from 325-800hp.
Andyrew, I think you nailed it with the Audi 2.7TT.
Nice strut towers Rudy! They look like really stiff nodes!
The Audi 2.7TT might be a good motor if you want to keep it German. Otherwise a Subaru EG33 or EZ30R with some turbos might work well too-and they'd help lower your CG to boot.
Why are you thinking of moving away from the Coyote? AFAIK they are pretty robust motors to ~650hp (forced induction).
I would love to see a small displacement motor - probably a six-cylinder - with quad turbos - since you are ambitious. A target of 600-800 hp at the crank would be fantastic. I have changed my tune on what is "usable in a 914" since my car is so composed with only 590 hp...my car with a 275 rear could hold another 100 easily. Looking forward to what you choose - even if it is an RS4 variant. Cheers.
T
No need for extra complexity with extra turbos. Thats not going to gain power, just response. The 2.7 is plenty responsive with appropriately sized turbos or even just a single turbo like a precision 6262.
The biggest thing to do with turbo cars is pick the right turbo/s for the motor to eliminate boost lag and pick turbos that will efficiently work within the power range your looking for. From there you build the motor to handle the power, make it efficient and then start pumping in boost, timing, and fuel to make power.
My turbo system is a hair lagy but its only a 1.8L displacement, my efficient boost pressure range is 10-35psi letting me tune my boost curve how I want it. I can either turn the timing and boost up down low for the most torque I can make which will blow the tires off as quickly as possible and break things. Or I can give it medium hit and ramp the boost up as it gets higher in the RPM or time in gear to allow for more potential traction yet higher overall acceleration.
I do not know Rudy personally (but anyone taking this on - I'd like to meet) but through watching his build (much like Chris too) - it appears he wants to chart new ground - so to speak. The added complexity is the bait to chase - not the obstacle to be avoided - for the rare bird like Rudy that is! JMHO
Twin turbo's, superchargers, vee-eights, etc have all been done adnauseam - a quad turbo set-up on a hot v-6 with DI would be epic. If Rudy isn't that motivated to build something truly unique, I get it. I am not (but it would be otherworldly!)...

"I am not a fan of the Audi 4.2 RS4 engine" neither am I. CSDILLIGAF has succeeded into talking me into the Audi 2.7 V6 twin turbo.
jd74914
I thought you'd like those strut towers. I still need to add some gussets. I'm kind of steering away from the coyote for a couple of reasons. The coyote is a great motor but Chip has swayed me into the 2.7 audi because you don' t need adapters and special clutch assemblies. And, I like the way that turbo'd cars pull. Additionally since we will be doing the same exact car, we can brainstorm and have a better chance of success.
I totally understand the CG issue but I just don't like the way that 4 bangers sound.
Cracker
Thanks for the compliments. You and Tigaboy are so hilarious in your writing styles.....I love it. Sorry to let you down though, but no quad turbos, two is enough. I think that the pull on the 2.7 will be enough to give passengers vertigo. I'm hoping that the car will get better traction with a controlled power band up high than down low where it will just cause wheel spin. It's nice to know from real world experience such as yours, that the 914 can handle an additional 100 hp over your 590. Wow that says so much for the amount of performance that is locked up in these little cars that we love. I look at the fact that my car's track is now 5 inches wider, the wheelbase is now 3 inches longer than a stock 914 but 7 inches longer than a 911 and a chassis that will be at least three times as stiff as a 911 and weighing as little as a stock 914, I feel confident that it will not disappoint. It is quite telling that the new 911 is the same wheel base as a 914.
Andyrew
The 2.7 will have the twin RS6 RS turbos.
I'm getting really close to bolting up the suspension. Just need a couple of gussets and the roll bar diagonal and it will be ready for the suspension. Then I'll replace the floor and close up all of the holes I made to insert chassis into the chassis. I will be adding shear connections along the floor pan, the dash and the targa to transfer loads between the chassis plate elements and the tube chassis axial members. In other words tie both chassis together so that they supplement each other where the other is weak.
2.7 with RS6's should be a lot of fun. Are you going to get the JHM one's?

What engine management and fuel are you going to go with? We could talk Audi engines all day...
It will be interesting to see how you build the motor, what you do with fueling, engine management, tuning, clutch, ect ect.
The 2.7 is a nice sounding engine, I will give you that
Dyno for comparison.
Andyrew
Yes the JHMotorsports ones. By the way that looks like it may be the dyno sheet for the JHMotorsports RS6 car? Is that it? From reading your posts and the impressive tuning that you have done it looks like you will be an excellent source of input on the Audi stuff.
JD74914 here are the gear ratios
1st gear 3.307
2nd gear 1.95
3rd gear 1.407
4th gear 1.133
5th gear 0.972
6th gear 0.822
Final drive 3.875
Rear tire will be 335/30-18
Put it in your spreadsheet or if you can, send me the spreadsheet and I'll post the numbers.
Rudy, the gear ratio's on the G87.21 have taller 1st and 2nd gears as listed on the California Motorsports page. They are 3.307 for 1st and 1.95 for second. That's another reason to use the G87.21.
Plus your tire is a little taller than mine. Yours is 25.9 so you can stretch out the revs more than mine.
JD74914 I calculated the tractive force based on the Boxter S G87.21 gear ratios and the S4 Stage 3 Dyno plot and this is what I got. Seems like a smooth transition. Looks like Porsche knows what they are doing in selection the gear ratios.
Attached image(s)
That is a nice smooth parabolic curve-perfect! That's what I've noticed too. If you plot curves from many manufacturers there are some big gaps, but Porsche and Subaru seem to have the gear selection thing down pretty good (for the ideal "go-fast-car" case).
I pulled it last night too and got a very similar curve...sorry I didn't get a chance to post to save you the work. I pulled a number of gear ratios from CM's website and the G87.21 really does seem like a good choice. It's a shame first gear isn't slightly longer, though this seems to be a "problem" in almost all gear boxes (it's really bad in sport bikes).
Copied this from my thread...
Finished the strut towers with the gussets that were needed. I should be able to bolt up the full 996 suspension this weekend

Rudy - That's looking wicked! (that's a good thing...)
Can't wait to see the suspension bolted on and this thing on wheels. I'm waiting anxiously to see the extended wheelbase and how you're planning to mod the body, etc. Any details or plans you can share now? Inquiring minds want to know...
Either way, keep the great work and progress pics coming!

Wow I though that the rear shock towers would take me about an hour each and it took a full 10-hour day to complete both! Anyway here are pictures of the rear shock towers. I took a piece of 6" channel and made a paper template and cut with plasma cutter. Ohh...I'm picking up donor car today. It is a running Audi S4 with 130K miles. Picking it up in Van Nuys tonight. The only major thing left to purchase will be a boxster transaxle. I was hoping to be able to bolt up suspension but that will have to wait until next weekend.

What are your plans for intercooling -- air/air or water/air?
For simplicity ( I know it's an oxymoron for this build) I am going to use the factory setup. I think that it is air/air. Since I am planning to open up the back end 2 1/2" on each side to accommodate the wider 996 track, I will take advantage of that and place an intercooler on each side but most likely 50% larger and mounted vertically. I will fold the rear 1/4 panel into them and create a reverse scoop to drag air into them. I plan on venting out through the rear in between the tail lights with some type of expanded metal. Maybe like the one that is on the engine lid.
Factory intercoolers are air to air and are not very efficient. They make thicker intercoolers specifically for the S4, specifically chineese versions that are very affordable. Combine that with E85 or W/M injection and you should be good for a considerable amount of HP.
I would go something a hair larger like this if your considering staying air to air.
http://www.ebay.com/itm/Rev9-Turbo-Side-Mount-Bolt-On-Intercooler-For-300zx-Z32-90-96-Fairlady-Z-VG30-/381440476746?hash=item58cf9fc64a:g:zAMAAOSwAYtWIXMO&vxp=mtr
But you would probably be better off going with a pair of bar air to water intercoolers and just mount a single large radiator in the fender.

Noticed forged diverter valves, Thats a plus
Pull the ECU and see if there are any markings on it. I bet at the very least this car was tuned, probably sell that ecu for an easy buck if your going a custom engine management system.
There really is not an affordable option for a stand alone engine management for this motor. There are people who tried with a $5K version or more and had nothing but trouble and never got it to work right. We want to build a car, not take a year to learn what others already know and are good at. The factory ECU has a huge following and tuners with the education and skill it takes to hack and do what ever you want are plentiful. I have found Motoza Performance to be the best, easiest, most helpful and cost effective. For around $400-$500 they give you the software to reflash the ECU, the cable to do so from a laptop and OBD2 port and the first version with the basic tune. This allows you to get up and running and run the data logging that gets emailed to them and they will tweek things until you are happy. If later you go up to bigger turbo's or go to E85 you just pay the difference of the two stages pricing and they help you out again.
Andrew thanks for your input. But yes we're sticking to stock engine management with tuners that work with them. Thanks for the info on those forged diverter valves, I didn't think they were stock but really didn't know what I was looking at. I have a lot of learning to do on this motor. I'm glad you're around so that I can glean information from you. As far as intercoolers im thinking of going with this company http://bellintercoolers.com/how-to-order/core-inventory/3-00-core-thickness-airair/
Ok so now I'm the owner of a Cayman S G87.21 transaxle. Should be here by Feb 6th. Well looks like I'll be pretty busy from here on.

Megasquirt has been effectively utilized on that motor, but I agree the factory ECU is more than capable. I am utilizing the factory ECU as well and know it has and will support my setup just fine as I ramp up the power.
Seriously pull the ECU, Most tuners will mark it. You might find it tuned by a reputable tuner who will set you up on a big turbo file and give you advice on what you need injectors, fuel pump, maf, ect ect.
Custom intercooler is a fantastic way to go on a project of this nature. If you have the ability to weld aluminum I really think you should build a twin air to water intercooler setup in front of the engine (you will have plenty of room).
This will allow you to keep the intake plumbing short and in the engine bay vs having to shoot to both sides of the fenders. Should help with spool as well.
Yes LSD from CMS motorsports. Chip already had his done. Paid $1650
CMS motorsports sells and installs the Wavetec LSD. They are $1255 plus install. Everyone has good reviews of it and it is made in the USA so I will give it a try. I have always had Quaife so the Wavetec will be new for me. Anyone have personal experience with them?
Well tranny came in today. Lifting car off of jig tomorrow. Will do a twist test before installing suspension. Huge milestone
Good for you...congratulations!
T
Well she's off the jig. Im going to try and do the twist test today. However, I have to smoke a briskett for the super bowl so the twist may have to wait.

Bolted up rear suspension. After everything is dialed in, I will bead blast the entire suspension and powder coat the calipers in red.

Looks like you stretched the wheel base just the amount you wanted too. Looks good. And the one tube you thought would be close at on the rear suspension looks like it just cleared. Can wait to see it on the ground with wheels and tires.
Thanks guys, I know what you mean I feel the same way. Just picked up a set of rims and tires so that I can use on the "roller". I didn't want to roll on the Rivieras so I picked up these 996 Hollow Spoke Turbo Twist wheels. They are 18x8.5 F 18x11 R.

Mmmm good choice of wheels
Well I have half a roller. Tomorrow I hope to bolt up front. Will be rolling by saturday. I'm really digging how the car looks with the extended wheel base. It puts the rear tire closer to the rear bumper and gives it a more cat like stance. I can't wait!!!!

Edit your first post, up top there will be the ability to edit the header. (Full Edit)
Rudy - you need some "body" to go with that "wide"!
Looks killer. What are your plans for the flares?
Its going to have mudflaps like these.

Sorry, I don't see the milk crate so no points...
Seriously - what a COOL look! You have to be totally psyched to have it on wheels.
Congrats on a major milestone!!
Looks fantastic!! Congrats!
Way to go Rudy!!! I knew on Sunday with no rain you would be up there working on it. I am digging' those wheels on it. And the Momo Steering wheel is a nice touch.
Sweet!! That's awesome!! Can't wait to see it at ride height with some flares!
Could you take a side profile shot? I'm just curious to see how far the rear wheels really are back.
Lets go, start dropping in trans and that Audi is not gonna pull its own engine!
I just got back from California MotorSports in Lake Havasu Arizona after having them install the Wavetech LSD in the Cayman S 6 speed. I have been working on mating the trans and engine so Rudy and I know what to expect. If I work out those details it will speed along the process for him and he can focus on other parts of the build.
I have a Fidanza aluminum flywheel and an RS4 clutch package. First there is a 1" thick spacer on the crank face of engines that came from an Automatic equipped car, I put steel rod in the holes and tapped it a little while going from hole to hole, popped right off. Warm up the flywheel so the hole grows enough to slip over the crank locating boss. The bolt holes will only line up one way, they are not equally spaced. If you warm the flywheel to about 180/200 degrees on a hot plate it will give you time to align it with a bolt or two before it tightens up. Use the 1mm thick shim from the automatics flex plate in the same location under the bolts to prevent galling and help torque to correct specs.
I will make a drill fixture plate with bushings so that three stud holes can be drilled and tapped along the bottom of the G87.21 trans making it fully bolted to the Audi 2.7T.
It appears that the Cayman S trans has a boss that needs to be drilled out for the crank sensor. The boss is in the same location as the Audi manual transmission and I have seen it done on an Audi swap into a Boxster S in the UK.
We will need to use the transmission spacer from the Audi automatic trans that is 7/16" thick. The RS4 clutch disk fits on the Cayman S spline and the pilot shaft fits into the pilot bearing perfectly.
Now we just need to figure out the Vehicle Speed Sensor. Maybe something mounted on the CV joint. It is a magnet pulse type. Rudy has one from his parts Audi and I purchased the sensor and the pulse ring new. The pulse ring is smaller than a CV joint so we may have to try and replicate the pulse some how. Any electrical engineer types out there that know how to figure it out? Here is the basics of it.
http://forums.quattroworld.com/s4s6/msgs/228211.phtml
Maybe we can adapt the 996 abs sensor and reluctor ring to duplicate the pulse?
Attached thumbnail(s)
Regarding your clutch. A standard B5 RS4 clutch isnt the hot ticket now adays. Apparently the B7 clutch pressure plate is that much better. This might require a custom flywheel, check into the S4 forums to find out what they are doing. If I swapped out my clutch again ( I have a stage 3 S4 clutch) I might go this route.
Regarding your VSS You could simply count the pulses on the stock VSS pickup, fab up that many 1/8-1/4" steel teeth and weld them onto your CV flange, then fab a mount for the VSS.
It may not be the hottest ticket but I think it will hold the power for now and was cheap. Now Rudy may want to look into that because I know he will be looking for more power than me. I will be at 375/400 with 550cc injectors and Ko4 turbos on E85. And may still have to go with something like the stage 3 like you have now. I just really like the ease of a build that is bolt together with no custom and expensive parts.
I have done the flange modification you mentioned for the VSS but it was on an LS swap and the sensor had the magnet in it and was an easy set up to do. It looks to me like the Audi VSS has the magnetic pick up in the reluctor wheel and if flips from North to South? I suppose I could use magnets in the flange this time and just flip them according to push and pull magnetic field?
Coming from ignorance here...
Why would there be a separate vehicle speed sensor when there are ABS sensor and reluctor rings on all four corners of a 996?
Maybe, as stated earlier, the wave form is different.
(I plan on doing a VW/Audi swap, too. Someday....)
Rudy or Chip -- What is the hub face to hub face dimension across the rear suspension?
Ah, yes. I remember hearing the early 986/996 had a 3 way ABS system that was virtually standalone.
Rudy has his to a point he could check that. He says its like 5" wider than the stock 914 but maybe he can verify. I'm out east of you in Alpine if you ever want to stop by and check out my build so far let me know.
I suspect we will have to figure the pulse/wave thing. I see on my axles that the ABS ring has like 80-100 teeth so with modification maybe something can work out there.
Hi Chip,
I visited you a couple of times five or so years ago, to see your 993-based car.
I am glad to see you are still tinkering on 914s. I have since moved to Idaho. But I brought my 914 with me. Gotta change my profile...
Andrew, When we get to that stage can we count on some help in the gauge cluster dept? We both are going to use the Audi one like you did. Looks close to the 914 and would nice to keep it. Did you have any warning lights that go off in the cluster or are they programed out by your tune? Like ABS, Check engine, air bag and the sort? I don't know what to expect really.
ABS triggers a chime in the back of the cluster that I disconnected manually. Air bag light is on, but the check engine light doesnt come on as all the sensors not used have been coded out.
I'll be putting some resistors for the air bag light or simply remove the bulb. I plan on using the ABS stuff from the Audi so that light will stay in.
Rudy - ABS is for wussies...REAL men lockem up at great speed; REAL drivers do it occasionally too. You do not need braking nannies...
T
P/N 99635575503 is the unit most people use IIRC. I've actually got one on order. The hard part is finding the unpinned mating connector.
Jim I think I may just give the 996 ABS a look. Is this the system that I should be looking at? It is a 2 pin connector.
Attached thumbnail(s)
That 2 pin connector is the ABS pump for the stability control system. Basically it primes the ABS box to allow for the system to hit any of the brakes at any time. Its similar to the Audi pump in design.
The first pic is the ABS box. That takes a multi pin connector, similar to the Audi. (See below)
Your going to have a 10x easier time if you use the Audi stuff as your donor chassis is already wired for it.
Interesting-I haven't seen one like the second one before (note that I have almost no 996 knowledge). People call it the pre-pump? Not sure exactly what it does except that it's for PSM.
The one the 951 guys use is out of early Boxsters (and maybe 996s since it does have a 996 P/N) and looks like this:

Man you guys and your wiz bang technology. I am anti-tech. I want minimal things that don't break down or have to spend a month to sort out. But that's just me, I'm still trying to conquer posting from my Iphone.
Adding absolutely nothing helpful to this current set of posts, I have to say:
I am in awe of you guys who "get" all this new-fangled technologlogicalnessism.
Makes what I'm trying to do feel like working with Tinker Toys. OK, maybe an Erector Set.
Really, it's impressive what you're up to. Keep up the great work!
Scott - I'll muddy up Rudy's thread (at least) one more time...I had taken a hard look at Bosch's Motorsports ABS M4 system/kit in the past. Most people whine about the cost - anything at the pointy end of development comes at a high price. What are you thoughts regarding programming/calibrating such a system to a 914 on slicks? The appealing upside to me was the adjustable slip that can be selected based upon a number of conditions and driver preferences. Until someone else surfaces with video of locking up the front brakes on a 914 at 165 mph (not something to be proud of, just experience) - I believe I am the only one with direct experience. I see the value of such a system near the limit - just not for a hot rod, doing hot rod things.
Tony
Scott - I was referring to Rudy's car...LOL! You are correct, however, I mainly just to stick that out there to poke at Bob Saville (who happens to have a legitimate 914 race car!).
I only have a hot rod.
Thank you for your insight regarding the M4...I cannot offer an argument against it and it would make driving at the limit a whole lot easier - to mention the added confidence it would provide! The faster one drives, using technology to ease the drivers workload becomes more and more critical. No different than the go-fast gizmo's on my prototype buggy...
T
So after this round of A....BS talk it looks like the Audi ESP is out of the picture. I'll still take a hard look at the ABS of off a boxster.
Hey. I didn't start this stuff...I helped put a stop to it!
T
Well motor is out of the Audi. It was amazing how these things are packaged. True nightmare to work on in the Audi but won't be a problem in the 914. Heck I'll be able to walk into the engine compartment. Great motor, but the way it is shoved into the Audi, it sucks big time. You forget how short these Audi V6's are. It measures about 18 inches long. So it's about 6" shorter than an LS1 or Coyote. Makes sense since its 2 cylinders short.
^^^ Well I separated the Audi motor from the triptronic and weighed it with , alternator, power steering pump, air conditioner, Ac drier, full of oil, headers, turbo , electric harness and torque converter. It weighed......a little shy of 440 lbs. I wonder how much a wet and fully dressed LS motor weights. I need to compare apples to apples though. Therefore the LS motor must have flywheel, clutch, exhaust headers, all peripherals, electronics, fuel injection, and intake system. Has anyone weighed this or have good information on this??
So today's project was to get a drill fixture made so Rudy can have more bolts to hold the engine and trans together. I took the adapter plate and put it on my CMM to measure hole locations. Made the drill fixture with two locating pins in the alignment holes and four long drill bushings for the lower four holes that line up on the engine along with two hold down bolt holes. The Cayman S 6 speed has solid bosses at the correct location but Porsche does not drill them since the Cayman motor does not need them. Its nice that they are there though. Now we can use all of the bolt holes in the engine. I think it will be best to drill and tap the trans and then use short studs as needed. One of the holes is bolt that holds the starter in place and sliding it on a stud will help.
Attached thumbnail(s)
The flywheel, clutch, PP and adapter plate for the LS to G86/87 variants is substantial, heavy (and pretty). I didn't weigh it but would guess that it alone weighs about 55 lbs. Chris could weight his since his is still accessible. My engine only has an alternator and dry sump pump and weighs 425 lbs. A baseline comparison for power goals to engine weight - 586 hp and 553 torque - at the crank. Idles smooth, and can drive at idle with no throttle input. Very docile.
T
Thanks T. that LS7 is legendary. The little V6 can't compete with that monster. Chris if you get a chance can you weigh your LS3 fully dressed. Please include headers and clutch with adapter plate if possible. I've checked other sites and they say that GM's official fully dressed weight is 497 lbs but it doesn't include clutch and adapter kit or headers. Therefore, if I read T right then, I suspect that a fully dressed LS motor will weigh around 497 + 50(clutch and adapter) + 20 (headers).= 567 lbs. Does that sound about right?
I went down South to Chip's house and he tapped in four additional studs to the Cayman transmission. You can see them in the first picture (Chip's motor and trans). He machined up a trick jig and was able to set it up and tap the trans in about five minutes. For those of you that may want to do this, these studs are not mandatory but we like our belts and suspenders around here.

So my wife meets Rudy when he was here and when he leaves she asks "did you guys work on the Paudi" as in Pow-Dee. She thinks she's pretty funny
That should be your license plate
OK this weekend I mated the Cayman Trans with the Audi motor. I started removing all of the excess piping and tubing that are unnecessary . It really started to clean that rats nest of tubing up quite a bit. I'll post pictures when done. Hoping to place motor in this weekend and then make the motor mounts. Chip will then start mocking up for the custom headers. I'd like to have the motor completely bolted up this month since I will not be able to work on the work for the first two weeks of April.
My remaining schedule should look like this:
April: Complete the new floor pan and button up all of the access holes.
May: Complete radiators with AC system.
June: Complete brakes, and fuel system.
July: Complete electrical system and start the car.
August: Complete body with steel gt flares
September: Complete custom body work
October: Paint
November: Interior.
We will see how it pans out but this is the schedule until reality hits hard.

That is one ugly @ss motor with all those hoses, wires and such, should look decent cleaned up!
I'll post a before and after picture. I'm removing the activated charcoal, the pcv and the secondary air pump. Ill build a puke tank for the PCV. Andrew whats been your experience on this?
SAI is emissions only and can be removed no issues.
Removing the charcoal/pcv isnt an issue you just have to have a place for the air to go, Puke tank works well, I have mine puking to atmosphere and it makes quite a mess. 034 motorsports makes a 1" billet adapter to the charcoal tank so you can route your puke system from there.
Another thing you have (2.7 vs 1.8) that I dont, is under the intake manifold you have a small bosch water pump with hoses that pumps water through the turbos / engine after engine shut off. Its common to remove that system as the hoses crack or the pumps leak.
Now my water pump ECU does something similar to that, but Im not sure if you want to retain that feature. Its something the ECU controls if the oil temp gets to a certain point.
I would start discussing all this with your tuner now. What do they need, What can you remove. Thats what I did, and they guided me to where I was.
Ask them about fueling, injectors, pressure regulator, Map sensor, MAF sensor, Boost control. Those are all things that need a serious discussion before parts bought.
Rudy, hábla me cuando empiezas el Aire Condicionado. Tengo la herramienta prensado de manguera barrera. Kent
Andrew thanks for your response. I'm interested in how your electric pump also doubles as a secondary pump for when the engine shuts off. I'm actually still thinking of using the Audi belt driven pump for primary and the Bosch pump as it was meant to be in its original state.
My electric pump has its own controller that when the key is off and the engine is hot will run the pump and fans for a couple minutes. I can program the temp at which the system trys to stay at from 140-205deg.
Rudy can you give me the phone#of the fellow in menefee that you mentioned who knows fuel injection systems and has a shop thanks Bernie
Well I we were able to place the motor to check for clearance and glad to say that it was a success. I'll have to adjust one tube to clear an oil filter but everything else fit great. Next step is to order some Z06 motor mounts and tie the motor in place.
Attached thumbnail(s)
I know I'm not the first to say this, but:
THAT... is a lot of wires!
Here's to success as you get to hookin' up all that!
And Triple Super Bonus Points for being the only 914 (I've ever seen) where the motor/trans goes in from the top!
Whats crazier is that that white taped up lump I am going to say is the rest of the engine harness wiring
The biggest issue facing conversion owners is the wiring goes the wrong way, requiring us to extend the factory wiring or cut and rewire most of the engine components.
It not THAT big of a deal because most of the engine bay stuff gets resistors on it and is not used. My local tuner is building wire tuck wire harnesses for the 1.8's, I might pick one up and rewire my engine bay because I have a big loop of wires that are just unnecessary.
I can machine and fabricate any thing but when it comes to wiring about all I know is red wire + black wire -. When I look at the bundle of harness I am intimidated for sure. Rudy seems to have a grasp on it and I ran across an Audi mechanic that loves the 2.7 and will help out as needed. Keeping fingers crossed.
Probably one of the most critical areas of emphasis in race cars are the electronics. Nothing matters much about a build if it is plagued by electrical gremlins (which can lead to: failures, fires, blah, blah, blah). The difference between the quality of electrical components and emphasis on such is often under-valued...or misunderstood. In a complex car like Rudy's...I believe nothing should get more attention than the electrical system, nothing. Good luck Rudy...
Tony
Tony I agree 100% the devil is going to be in the wiring with all of the sensors and actuators. Also need to make sure that there are no boost leaks. I plan on taking all the time necessary to get the wiring done right. Will lay out the entire system on a huge table and check every wire and connection. I have a close friend who is an electrical engineer and has written multiple university textbooks. Guy can make his own chips.....as in designing the circuit and actually building the chip in his garage. I think with him and the knowledgeable folks in this board I'm going to be all right.
Andrew yes that big lump is the wiring harness. I wrapped it in cellophane. I'll sure be needing your's and Mike Bellis' input when I get into it.
By the way, I'm checking out for a while on vacation.
TTYL
Hell, I hardly ever get passed the red/black on the battery but that does explain why most everything I try to wire smokes.
Edit:
Now I am curious since I have never had a 914 that did not start as a gutted shell with out any wiring at all is the battery ground brown as well?
Well look what came in the mail today!

Whooo, Snailbrackets
Wow Rudy! That's a lot of work.
Have to agree about wiring issues. I witnessed Dave
(914dave) dealing with his harness and the 3.2. So many roadblocks with power not
going where it's supposed to.
All sorted though.
Rudy, looking fantastic. Nice progress. Carry on...
Cheers, Dion
Rudy and I discussed the header plan. At first I was going too make us both a set and go equal length and relocate the turbo's to a better location for our needs but then in the interest of speeding up the process we decided to go cheap to get it running. We were aware of the cracking issue but Hell, at $135 they are disposable. We will most likely chop and modify them at least once. So consider them mock up.
I went through a similar issue with my 1.8T. I bought several headers/manifolds trying to find the right location for my turbo. I had a nice SS equal length header that I cut up trying to realign the turbo housing to no avail. A $79 ebay special ended up being perfect. I still have about $1,200 in exhaust manifolds collecting dust in my garage...
cheapy's will work for testing but a little more money and these ones made from 1 1/4" schedule 10 stainless pipe would be better when time to finalize things. For what they cost I can't buy the flanges, elbows and pipe and then weld them up.
http://www.ebay.com/itm/3mm-thick-MANIFOLD-HEADER-EXHAUST-1997-02-AUDI-S4-B5-A6-C5-QUATTRO-2-7L-BI-TURB-/122006739130?hash=item1c682b18ba:g:c0EAAOSwLnBXUXL0&vxp=mtr
Ideally I want to delete the pig tail curl they have and lower the turbo with the outlet angled up slightly to clear the axels. We'll see if that is what works on Rudy's first.
Edit: They are XSPower. With some research on XSPower turbo headers I found
"XS Power is proud to be partnering with Stainless Works"
"Stainless Works manufactures them on-site, right here in the United States"
OK Rudy's lets see if with all the emission and things we don't need if you can get rats nest of wires to look like this?
Attached image(s)
Hahahaha. Seems to me like that car does not run. We're getting rid of the evap, the secondary air and pcv. It cleans up quite a bit. Getting it to look like that may be difficult. We will come close though. The problem that we have is that al of the wiring is along the firewall of the Audi which can hid the wiring. In our case all of our wiring is visible since it's mid engine. We will have to come up with some fancy way of hiding the wiring.
For me the biggest thing was there was so much stuff to fit in the engine compartment something like this was no way a possibility. I mean the piping for the intercooler take up a considerable amount of room and you'll have two turbos to pipe to either one A/W IC or run twin side mounts.
I agree Andrew the piping for the intercoolers will take up space. However, I have the luxury of not having a rear trunk and rear firewall. Therefore, since I am going to create a side vent into the engine compartment at each quarter panel, I will be able to fit the intercooler in such a way as to simplify the plumbing. The side vents will fold into the quarter panel rather than protrude like a scoop. They will follow the angle of the tube chassis as it tapers from the B pillar rollbar to the where it pinches at the rear suspension. I'm toying with the idea of making the vent, as it folds in, out of carbon fiber. I set the intercooler in place and it fits perfectly. The intercoolers wil be set in such a way that when the rear hood and rear fenders tilt back, the intercoolers will be exposed. See attached for a preview.

Wow it's been a while. Was out on vaca and had to dig out of a ton of work. Back on the project now. Had to make a lifting cradle since I need to lift the engine out of the car often. This contraption worked out perfectly. The next step is to fab the engine supports and finish the last chevron brace in the rear. I'm ordering a new floor pan since that is the next order of business once the engine is tied into the frame.

Rudy - Good to see you back at it.
I'm still weeks away from working on mine...
It's nice to be back. Hope you get better soon and are able to get your project going again. The time off has been good to get the creative juices flowing again.
Well I got the car back on the chassis table to level everything up and place engine where it needs to be. I like its final position. The oil pan is 1/2" above the floor and the engine sits almost level. The engine and transaxle are shoved forward as much as possible. This will give me a more balanced car in conjunction with extending the wheelbase 3". The next step is to weld the engine mount s. After that it will be floor pan and finish buttoning up all of the welds and covering up all access holes.

It's a bolt-together joint. I used a couple sets on a 911 rear cage. They're fantastic.
Attached image(s)
Exactly. Andrew they will be used for the couple of cross bars that will go over the engine/transmission bay. That way when I need to remove the engine and trans, the y come out as a unit over the top. This car is being set up to be able to remove the engine and transaxle easily for servicing.
Some more progress on the transaxle mount. It ended up being very tricky since I did not want the transaxle mounting bolts to have any tension on them. The factory was designed with tension, but since I am adding a much longer ecentricity to the new brace it will add too much tension on the factory bolts. I cam up with a way to tie them together so that there will be zero tension on the bolts. They will only see shear forces. Almost done tying the back end up.

Here is the how I'm doing the front engine mounts. After this weekend I'll be move to the front struts. I need to lower front end 3 inches. I have a solution that keeps the 996 struts and coilovers. If it works out, then the car will have 3 inches of ground clearance but with the stock suspension travel. More on that later.
Attached thumbnail(s)
It's not sitting flush cause i haven't tightened the nut. It will sit flush then. You have a good eye Andrew.
OK the engine is finally sitting in its custom engine and transaxle mounts. Took way longer than expected. I still have to complete welding but I have to remove the engine and transaxle for that. Next step is to work on the front struts. I need to lower the ride height 3 inches in the front.
This is the front engine mount.
This is the way I tied the transaxle mounts to each other
1/2" clearance from the floor pan on both engine and transaxle. They are on the same plane and the motor and transaxle are almost dead level. I will tie the entire bottom of the engine/transaxle bay together with one single aluminum plate across the entire engine/transxle bay opening. It will be tied to the factory suspension bolts and to the tube steel chassis. This will completely tie the opening together and take out any flex in the truss system. The load will then transfer into the floorpan thereby removing any lateral deflection in the chassis. I will also take the opportunity and blend the structural element into a diffuser.
Look at what I picked up.
Attached thumbnail(s)
flatbar under trans ...looks so ...you finish the sentence....
awesome jiob
Seems like a nice place to mount the diffuser to me
Well now that I'm moving on to the front struts, I know that I need to lower the ride height 3" in the front. So I started to think how I can determine how much I can raise the strut tower up into the hood while using the 996 coil overs and thereby having a lowered car while retaining the stock ride and adjust ability. I'm shooting for 4" of clearance to the pinch weld of the longs.
Well I went to a hobby store and bought some foam that they use in flower shops. Then I cut and sandwiched the foam in between the strut tower and the hood. Then I closed the hood and I got the mold that I needed. Kind of like pressing a panini.
Here is the mold after pressing it.
Here is the bottom view
Then slice at the bolt locations and get the clearance dimensions from the hood. Looks like I will be able to shove the struts up into the trunk another 2 inches.
And that's how you slice it.
Now I need CSDilligaf to machine the shoulder of the lower strut to be able slide into lower strut mounting point another 1 inch. Then I'll have my 4" of clearance "unloaded".
Tomorrow I'm going to Chips place and he is going to put the lower coilover in his lathe and cut out enough meat to lower the base of the strut 1 1/4" into the aluminum 996 upright. I'll be finishing this portion of the build this weekend and will post pictures of it sitting at the correct ride height. It will have 4" of clearance on the front and 4 1/2 on the rear without lowering from its stock position.
This is where the strut installs into the aluminum upright
This is where we are machining the strut to be able to lower it
This is what the center console will look like. I'll be able to
run all of my wiring and piping through here. It will be covered
in carbon fiber and will be removable for access. This will add
extra rigidity to the frame as well.
I'll post pics once it's sitting on it's own weight. Next step will be to remove engine and suspension and finish welding everything up, add the center console. Will be ordering floor after the 4th and then install that as well.
Nice! You're inspiring me to get back working on mine. I, too, have a custom center tunnel to fabricate... Great minds, eh?

AFTER 4" Front, 4 1/2" rear
Significant! Thats right where it needs to be. With the longer wheelbase it will look even lower!
Looks good with that flare on, Rudy. Will the flare work on the rear or will you need to add some steel to extend the rear flare out a bit? How much will a set of tires that can handle that speed cost you?
That does look good Rudy. Now on to buttoning up some area's that need welding and fill in some sheet metal and you'll sitting pretty good.
Very nice! It looks awesome Rudy!!
Rudy-
I'm in awe...
Just amazing progress thus far.
It already looks scary fast.
Keep going my friend....
Oscar
Ok, I just finished binge reading this build story and am in awe of the vision, skill, and perseverance to make this happen. But, come on! You can't leave it hanging... must have an update on progress.
Nice...welcome back
We missed you
Oscar
Glad to hear your back Rudy! Hope everything's going well!
He's BAAAAAaaaaak!
OK, enough with the celebrating. Let's see some progress and pics.
Good to hear, Rudy. I was going to stop by last week but figured if you didn't have enough time to work on your car then you sure didn't have enough time to chew the fat!
OK back on FINALLY! I started work on the floor. I removed it and now am waiting to get the replacements. I will be working on closing up the holes that I needed to put the struts through. Also, it's easier with the floor off. Should be getting a new set of shoes. 10.5 x 18 F, 15mm offset with 265/35/18 and 12.5x 18 rear, 0 mm offset with 335/35/18 Toyo R888R's. Track is 62.5" Front, Rear is 63.0".

Awesome! Whats the plan with the floor pan? Going to lower it some for headroom?
What up Rudy?
Are you working on it Saturday. I'll stop by if so.
A big welcome back Rudy!!!!
Yea, Rudy! Welcome back!
Thanks for the awesome welcome back. @http://www.914world.com/bbs2/index.php?showuser=172 @http://www.914world.com/bbs2/index.php?showuser=15191 @http://www.914world.com/bbs2/index.php?showuser=9964 @http://www.914world.com/bbs2/index.php?showuser=16669 @http://www.914world.com/bbs2/index.php?showuser=19241 Andy I'm just going to put the stock floor back in since the car is already low (4" clr) I don't want to expose my hindquarters and moneybags any more than it alreasy is. Kent, It would be better if you came by on the weekend after labor day. I should have the floor by then and will be installing it. Hopefully the new wheels will be in at that time as well. The break has been good, I've though over some things, changed my mind over and over but now I feel way better about some of the design changes. I am going with the radiators in the quarter panels and I decided against (for the second time) the hollow spokes.
By the way did you guys notice the front and rear track dimensions. It's a half inch from being 63" Square.
BTW does someone have the link to the guy that shows how to widen the steel gt flares? I've checked using the search but I was not successful. I remember that he cut the whole thing and added a strip to it. I will need to do the same thing and is the next thing on my agenda after the floor is welded back in.
Rudy - here's a pic that @http://www.914world.com/bbs2/index.php?showuser=209 posted on my thread about a flare widening update he did. Maybe check in with him.

I went thru all my pics. Most of the work is undocumented.
The process started with cutting off some crappy custom flares that had really thick bondo to make them smooth.
Then I carefully butt welded the AA GT flares in place and hammered the weld seams smooth.
Next I chose a cut line just inside the curved edge. The location was chosen so I could shrink the edge of the removed piece to match the new shape.
Then, using a modified palm nailer, I hammered the shit out of the part left on the car to raise up the top so the wheel opening would end up at the same height as on the stock flare, and I smoothed all the surfaces with hammer and dolly.
The front and rear edges were curved outward to create a smooth shape that would line up with the reworked edge of the removed piece.
After many hours of reshaping the loose edge I was satisfied with the transition and clecoed the loose section in place with some small pieces of sheet metal to bridge the gap.
This is the point where I started taking pictures.
Thank you @http://www.914world.com/bbs2/index.php?showuser=209 this is super helpful
Well I started to install the flares. I started with it upside down cause it makes it so much easier. I painted both mating surfaces with weld-thru-primer before welding. Notice the rear fender how it encroaches onto the rear tail light. That is because I stretched the wheel base 3". I like the way it is fitting. I will need to add about 6" to the rear flare and 5" to the front flare. I'm waiting for the new rims to come it before I do that though.

Wow Rudy...
That's Bad Ass.
For those who don't know the meaning.
https://www.youtube.com/watch?v=RAGcDi0DRtU
Enjoy !!!
Oscar
Im jealous of the fun metal fab work your going to do
However only 1 fender would be fun, 4 would be repetitious and boring
6" extension of those flares is going to be substantial!!!
You might need a third cooler FYI. That 2.7 runs pretty hot. I would run an electric water pump so you can at least have as optimal cooling as possible
And your cars going to be awesome I just love everything about this build!
Hey guys I’m needing to borrow a sheet metal break for a couple of months. Does anyone have one that I can borrow or is someone willing to let theirs go on the cheap. Let me know.
Well I'm in the process of welding the fenders on. It takes me about 4 hours per fender. Here is how I did it.
First, flatten out the bottom lip of the existing fender. This is to give you a flat area with which to attach the new fender. At this time also cut the existing fender along the bottom edge.
Then attach the fender to the two bottom lips and weld. Then tack weld along the top center of the fender. This will give you 3 points where it is attached to the car now.
Then cut from the bottom to the top half of the fender an attach panel clamps. I found that using a thin cut off wheel worked the best. It gave a nice gap to weld and was not so tight that it would bind the panel clamps when trying to pull out.
Spot weld in between the clamps
Then remove and spot weld remaining gaps that the clamps left behind.
Cut and clamp the other half
Weld, remove clamps, weld, and grind. I find that it was super easy to grind with the cut-off wheel and then to finish with an 80 grit disk sander.
Amazing...
Pictures speak volumes thanks Rudy
Gee..I need more time off work
See you tomorrow for breakfast!!!
Oscar
Rudy - I know! You can come up to Petaluma and we can install my flares!
Seriously, that looks GREAT! Nice job!
Wow!!! Fantastic work Rudy!
The gap-police would give you a 100% + on your continuity
I think you could rent yourself out to install flares
1/8" cut off wheel? Who's wheels are you using the last set of thins I got destructed every time they spun up, after two of them launched across the room, I grew the tossed them away. Seen to many pictures of what can happen.
I dropped off my bumpers to Oscar and had breakfast w/ Rudy and him yesterday. I felt like I was in the presence of Royalty as I sat with these 2 metal-meister's. Afterwards I stopped by Rudy's to check his progress and snapped a couple of pic's. Very impressive build.Rudy took the time to walk me thru the flare install. He said it was easy peasy but me thinks it's a trap. Seriously, he made it look simple but I know better. Anyway, here are a couple of shots of Rudy's project.
Hey Guys , @http://www.914world.com/bbs2/index.php?showuser=16669 @http://www.914world.com/bbs2/index.php?showuser=19241 @http://www.914world.com/bbs2/index.php?showuser=172 @http://www.914world.com/bbs2/index.php?showuser=2755 @http://www.914world.com/bbs2/index.php?showuser=2388 @http://www.914world.com/bbs2/index.php?showuser=9964 thank you for the compliments they really do help with morale.....encouragement helps fuel the project.
Those butt clamps were amazing, and cutting it with the thin 1/32" cut -off while using the fender as the scribe line was the trick. Also doing one half of the fender at one time was very helpful. I used 0.23 welding wire and a 110-volt Lincoln. It worked perfectly! My 200 amp wire welder was too big and it didn't like to push 0.023 wire 15' in the gun. I didn't want to tig cause I'm not good with Tig.
Well I completed the 3 fenders and the last fender is all tacked in. It now needs final welding and grinding. It will take about 30 minutes to complete. Then it's off to the floor and finish the openings in the chassis.
As for the cut-off wheel I didn't know it, but I stumbled onto some super good wheels. I was cutting along no problems and then ran out and got another brand since my local welding store ran out of the ones I was using. So I bought this other set which was expensive and was surprisingly, "made in the USA", but was pure crap. It lasted 12" of cutting into the fender before wasting away. You could watch it reduce in size in real time......ridiculous. And then, dust everywhere. The original ones would last about 12'....feet not inches. So the EXCELLENT cut off was by Pearl and it was a 1/32" thick wheel. It lasts for one fender if you include grinding. However, I think that if I did not grind with it that it could cut all four fenders.....it's that good.
Here is the Excellent wheel that I used.
Here is the crap one.
Left Front Fender
Left Rear Fender
I love 1/32" cutting wheels! Like butter! I'll have to get these, as I always just grab a set at harbor freight...
This reminded me of another epic thread about flare method by Dan Root. Can't find it right now, but maybe someone has a link?
@http://www.914world.com/bbs2/index.php?showuser=15637 Rudy thanks!
Such a great thread and project.
I looked away for a while and some really cool projects have come along.
Keep it coming.
John
Great to see this project back on track...looking great Rudy! 335?!?! Holy moly pal!

Very cool Rudy! Here is my (small) 275 rear next to the gt40's 415...it would've been waaaaay to big!

Update pictures of center tunnel and floor. Ill be finished with the center tunnel this weekend and will start with new floor. I decided on making my own floor so we will see how it turns out. I still need to add the web struts at each end of the center tunnel and it will be complete and fully structural. I plan on doing twist test soon and will be testing it with an without the top bar that tie both the rear roll bar hoop and the front roll bar hoop. If the twist test shows 1 or 2% stiffness improvement....then they will be removed.

Looks great Rudy...is it going to weigh less than 3k pounds? BIG & BEEFY all the way!
Tony
It was said in jest...t will be well under the 3K# number.
Tony
Wow, this is great! Just read it start to current! Love it!! =)
All right now....I finished with the center tunnel. ADDED WEIGHT TRIGGER ALERT Never mind that it is accounted for and offset with carbon fiber. Next step is the floor. I am getting the Eastwood 28 inch hand beader. Hovwever, I have a motor that I am going to adapt. Then I am am going to add so much beading that it will make us all sick and I'll have to scrap it and do a more "normal" look. Also, I've decided on using inboard suspension on the rear and on the mac pherson strut front suspension. I want the ability to make the shocks to travel more than the wheel and I want the ability to create a rising rate motion with a linear spring. Any input on that is appreciated.

Looking great, Rudy!
Not sure what you're plans are for plumbing but a heads up on a lesson learned from my console:
If you're planning to run hard lines, make sure you have a way to get them in/out of the chassis, once the console is in place.
I'm likely going to have to slice up my console so they can be installed and/or removed/replaced for any reason.
Oops.
Its coming along nicely Rudy. I'll have to stop by on my next trip up that way.
Quick update, I finally finished welding the tube frame. My son is designing new lower 996 control arms to extend the front track 1" on each side for a total of 2". The control arm is getting a revised location for a strut to install inboard coilovers on the the mac pherson strut design. The mac pherson strut will be replaced with a sliding shaft and a monoball on a camber/caster plate. I think that this may be a first, not sure, but I haven't seen it on the web. While that is being machined by CSDILLIGAD out of a solid piece of 2026 aluminum on his HASS CNC mill, I will finish bead rolling a new floor. The 3-piece forged modular wheels were supposed to come in this week, keeping my fingers crossed maybe this week. BTW, I decided to convert the rear coilovers to inboard coil overs as well.
Question for the group, does anyone know the specs on the front ball joint for the 996 control arm? I need to source them for the new control arms. Any help would be appreciated. I'm looking for the length and taper and diamters. I'm hoping to find an off the shelf ball joint that I can press into the new control arm.
I like that idea. Are you going that route to try to improve motion ratio? How are you planning on making the sliding shaft? Gutted strut damper?
Fitment check.......they finally arrived!

My Lord!

Holy crap!
You couldn't have tucked that any more? Daaaaaaamn.
This car is going to be WIDE!
I LIKE IT!
This car makes a statement and it ain't pimping. Bad ass Rudy. I got a name for it. El Curendero
Thanks guys.
Andrew I based my offsets on hitting target track widths and was not concerned with tucking the rears in. The front and rear track are now square at 63". The interesting thing with respect to the rear offset is that it's a 0" offset so there will be less eccentricity on the rear wheel bearings. The car will be wide that's for sure. I measures 76 1/2" to the rear rim edges. I figured if I was going through all of the trouble with tube chassis and all, that I was not interested in making a meek rendition of the 914. I'm hoping that with the extra width and the 3" wheel base extension that it will look like a panther crouching and ready to pounce.
Obviously I need to extend the fenders but I want to keep the curve in them rather than a straight extension. I have a couple of ideas to do that.
Kent don't know about the Curandero Come on by and check the wheels out in in person. They are 3-piece forged rims with custom offsets. I really like the look.
Rudy,
Your essentially going to need to extend the fenders 5", The rear of the fender is where all that dimension is going to look the most odd.
I know you've worked with foam before, possibly a good idea to lay it out in foam and shape it a bit before you start cutting? Maybe do a wire frame of your potential wheel arch location and after putting some foil on your fenders to protect the steel spray some expanding foam on them in multiple layers and start forming it out?
Thats what I did for my V1 dash and it worked out really well. I had issues where I was trying to spray to much in one location and the foam never setting but in general a couple layers made the job easy and I was able to cheaply and easily template out what I want.
You could do this then make cardboard slices for what your fender line is and then be able to transfer those new measurements to the formation of steel?
Fun stuff ahead This will be really fun to watch! Wish I was closer
Oh I see, you extended them from the quarter panel. They looked good after you finished "massaging" them into shape.
Here is a shot from the rear:
Front Rim:
This is how much I'm needing to extend front fender + 1 1/2" since the lower control arm is being pushed out to give me the 63" square track.:
We're not messing around now!
Watch the Blinky episodes where they spread the flares WAY out
Here's the Binky Epispode.
https://www.youtube.com/watch?v=mB4NXA_vNWs&t=499s
Thanks! The Binky flares are fiberglass and I don't think much of that will transfer to making steel flares. Thanks though!
food for thought..
https://www.youtube.com/watch?v=PI0vpvaL7Vc
Close but not what I’m going to do. I want to keep the vanishing edge so when you see the fender from the side profile the current flat vertical area will shrink. The fenders will look more curved. Do you know if that car is from one of the world guys?
ya its boxy ,,, It was , has been sold , I dont know where it got of to..
This is what I'm thinking of:
Seems like the "flat" portion will be reduced by about 2 1/2":
I think that will work, just afraid of the rear section getting so tight.
That's why I was thinking you might need to foam it out to be able to try out a few options before you start cutting and welding.
Unless you absolutely have the design in your head your going with.
Another pic for idea refference. A more rounded fender.you can see the front fender is slightly flatter.
Thanks, Andrew for your comments and suggestions. I'm thinking that the final product will be like yours but edgier. I still want the flat design elements that are found throughout the 914. So it will look like yours but with a vertical flat element as found in the 916 flares.
Keep in mind, where "wide flared teeners" usually have issues is between 10/2 in the top center; and on the inner chassis if you run a reasonable amount of camber. Keep up the good work...remember, it doesn't have to be nicer than Chris's!
PS: I know you are already aware of ALL of this but get the tires on there - with how large they will be it will indeed have to be "boxy' to carry the edge.
T
I am sure you already know this but just in case, fully compress the suspension with tires on when hanging the fenders to make sure that the tires do not rub when bottomed out
Wow Rudy I just read thru your entire thread, you are truly building a monster, very impressed. Keep up the good wok.
Rudy !!
Oscar, unlock the italics button.
Hey guys, a little update. The project is still ongoing.....but I've been slowed down due to.......(insert typical excuses here). But really though, I completed the frame and am now working on the floor. I am waiting for a bead roller and English wheel that I ordered. The bead roller is a Mitler Bros with Covell forming dies and a host of other dies that I will use to make floor and to make the pieces that I will need to shape the "wider" fenders. The English wheel is a Metal Ace. I've also ordered a Roper Whitney 48" box break. Once all of that comes in I will be able to complete the floor. I'm also moving into a 50' x 24' shop. Up to this point I have been working outdoors so I really can't do much when it's too hot or weld when it's windy or work when it gets dark. Now I will be able to work whenever I feel like it so I'm expecting to get way more done. Also, there this month I find out if we sell our property of stay in it. If we sell, then I'm building a new house and then you know that this project will stall. If we don't sell then there won't be a stall. Also, I figured out a way to widen the front track of the 996 suspension without having to machine new control arms......stay tuned since it's very cool way that keeps all of the suspension geometry and can use factory parts.

Always nice to see updates from you Rudy. Keep that Monster 914 alive!!!!
You will be rewarded!!!

I'll be over to make a new pan for my BBQ pit once you receive the bead roller. Good to see your back on it. Which Car Dealership wants your property?
Awesome! I was wondering how you were doing the other day Rudy.
Can you pull the engine/trans package out of the top with those tubes removed?
Any updates on this beast?
Well after a long hiatus I'm back. I moved the project into a workshop with a bunch of new fabricator tools that I needed to complete. It's on!!

Wow! Looks larger than you described. I need get over there and check it out. Do we have an "envious emoji"?
Nice shop, plenty of space to work on the 914. Glad to see more progress on this car.
Whoooo!!!!
Looks like a nice shop!
John
You have an incredible number of tool chests.
Glad your back. Your thread is fantastic.
Dup post..
I've started building the floor pan
but I first needed to add the supports for the 914 seats
and for the Tilton pedal assembly.
I was able to shift the seats 1-1/2" closer to the center of the car and the pedal assembly 3" further away from the center of the car. As you can see the brake pedal almost aligns with the steering wheel centerline
By doing this I was able to more closely align the seats and the pedals with the steering wheel centerline. In doing this I found out that I am in need of the seat elevation control tab that attached to the floor pan.
If anybody is cutting one up let me know as I need this part.
ALSO THANKS EVERYONE FOR THE WELCOME BACK......ITS NICE TO BE BACK!!

Rudy's shop will give a Tool Whore wood. I've not seen Chris' but I'll bet they are similar. IIRC, @http://www.914world.com/bbs2/index.php?showuser=1319 had a car that was being cannibalized a few weeks ago. I'll probably drop by sometime this week while I'm waiting on parts.
we were just texting one another. I'll point him this way.
I have those parts.
I have on on a chunk of cross member and can cut it off.
The driver and passenger brackets are different. Is what you pictured the one you need or the one you have? I am not sure they can be swapped.
The one I have on the cross member is exactly like what you pictured. I think I cut both from the parts car.
Easier to ship unless you like to drive
@http://www.914world.com/bbs2/index.php?showuser=15637
hopefully that IIRC guy still has that part. If he's local I can come by and cut it out of the car.

Yes cut out entire cross member and I'll "surgically" remove the part I need. And you're right , the driver and passenger are different. I need the passenger side. PM me with price so we can make arrangements.
UPDATE: PEDAL ASSEMBLY AND 911 STYLE DASH
Installed the Numeric shifter. Cut 7/8" solid stock p0lugs and tapped for M6 bolts inserted into tube steel frame by cutting 7/8" hole and inserting tapped round plugs.
Used a sacrificial piece to be able to holesaw the offset round plug
Cut all the way through
Insert round plugs and weld
Install Numeric Shifter
Install foot pedal to frame
Foot pedal assembly is as close as possible to the center line of the steering wheel
Cut 914 Dash to fit into the tube frame
Installed Getty Design 5-Gage Dash.
I love 914 World posts that have virtually zero 914 content.
Great progress, Rudy!
I Like the
getty 911 topper and 914 lower, when peeps use the whole 911 dash ...Why ?? its a 914

Love the progress!! Thats a LOT of welding!
Rudy's work... "Checks all the boxes" !!!
Awesomeness!
Looking REALLY nice, Rudy!
Looks great Rudy. I need to stop by and see your progress again.
Danm how'd I miss this build.. Crazy!!
That is a lot of dimes. Nice welding.
Rudy
So thrilled you're still at it. I seem to remember that awesome BBQ you prepared us several years back.
Hope you and your family are doing well.
Keep us updated on your progress
THANKS GUYS,
The body work remaining is
1) make a front trunk
2) tie in rear trunk
3) finish interior long cover
4) make interior tunnel cover
5) flare out front and rear fenders and additional 5 or 6 inches.
suspension work remaining is
6) my son is currently designing and machining the front control arms to include a 3" front track widening and connections to remove strut and transfer to inboard coil overs.
I'm feeling like doing 2,3,4 and 5 first while son does 6. Will leave 1 once I figure out how to vent this thing out. I want to try something different.
CHECK OUT THESES LONGS!!! The are accessible now so that I can run radiator, ac and electrical lines in them. I created access. Used nutserts and dimple dies to attach with button head screws.
this is how I made the shear transfer
the floor is attached to the tube frame now in shear!
There are some wildly, wildly cool builds going on right now. And this is definitely one of them. Hat's off on the creativity, workmanship, and direction.
Can't wait to see this hit the road, but enjoying the journey...
Update: Completed both removable long covers. Did this so that I can run radiator and ac lines inside of the longs.
Using Langmuir Pro Plasa Cutter to cut sheet metal. I fabricated everything on the table that is painted red. Had to modify the table to my liking
So I cut out the long covers and a bunch of ac/vent holes that I'm closing up.
I closed every single opening along the firewall
I put an offset in the stationary cover so that the removable cover fits close to flush
Bending longs on magnetic brake
Adding rivnuts to make it all removable
This is what it will look like when open
This is closed
This is top view inside
This is top view outside
Closing everything up
This is what is coming next
Great update Rudy.....
Wishing you and your family a Happy New Year.

?Qué bola, Pipo? Wow! You don't post very often but when you do..............you put the rest of us to shame. Amazing work. Your killing it Dude. Can't wait to see this again. Hasta fin de semana.
A plasma table, bead roller and mag brake? Where have I seen that set up before?
Rudy - You're killing it! I love the removable long panels. Very cool design that you brought to life. Great work!
"This is whats coming next"
Holy wheels batman! Just Damn!
Going for the record tire on a street 914??
Thanks guys, Happy New Year back @ValcoOscar ,
@76-914 see you this weekend.........no more covid. I will have my new AC system by then. I'm going with a RESTOMOD unit
@horizontally-opposed thanks man....I can't wait either.
@tygaboy I don't know...........where? CNC mill and lathe are on backorder Bought a Precision Matthews 940 mill with Acorn CNC controls, and a Precision Matthews 16x40 lathe. Got something planned for the mill since it has the ability to do 3d contour mapping. Got a little dirty trick planned up my sleeve. You're going to love it.
@Andyrew I don't know if its the record but it will have a 63.5" front track and a 63.0 rear track.
I'm going to flare out the fenders next. Fronts are +4 and rears are +5 over and above what the 916 flare is.
I'm building a jig to keep the fenders in exact location so that when I expand them, they will keep the exact location as the 916 but just wider. I will also extend the curvature transversely along the rear hood. In order to do this I will have to make the face of the fender shrink by about an inch. Can't wait to see it sitting with the new meats and the lengthened wheelbase.
Ohhhhh and pretty soon I will do a twist test to see if I got this thing much stiffer than stock.
Wow !
That’s looking “rude” can’t wait to see it!
Hope everything’s going great.
One of my fave build threads hadn’t seen it awhile . Just finished a morning coffee in downunder oz and got up to speeeed
I just returned from Rudy's and all I can say is be prepared to be awe stricken. IA very humbling experience I must say. I'm not even sure that the trunk lid will remain stock. The welds are impressive as well. Such small, flat "dimes" on thin metal I thought they were TIG welds but they are MIG. Some upcoming metal work will be quiet involved with compound curvatures but I'll stop there and let Rudy reveal when it's time.
That looks awesome. Can't wait to see the finished product
Incredible.....
This is beautiful work.... but I have a question.
Looking at this picture:
I noticed the diagnoal bars on the bottom of the engine compartment. My question is: How are you going to get the engine in the chassis? The inside diagonal bars are in the way of lifting the engine up in to the engine compartment.
Clay
@http://www.914world.com/bbs2/index.php?showuser=9964 Thanks man.......but you're over selling it.........makes it harder to impress. All kidding aside, thanks for the compliment.
I'm moving on to flaring the fenders and making room for intercoolers in the quarter panels. Planning on cutting the 1/4 panel and bending approximately 30 degrees. After I'm done with it, you'll be able to carry luggage in there. It's not going to be a make-believe-vent .
A little look into what the ac system is going to be like
This is a RESTOMOD unit.
I will be adding aluminum diamond plate in the footwell area. This is my variation of AUTOCardboard.....sometimes I use foamboard.
I think it would work. Even if you have to cut the floor of the firewall to lower it say an inch it will fit any 914. Also, it beats anything out there with all the electronics. It's an amazing unit with electric servos. No wires to control air mix. This is infinitely variable mix too. They have the best billet air vents as well. Installed in this fashion it will leave all kinds of legroom. It's the way to go IMHO.
I'm thinking of using this style of vent
LET THE HAUNCHES BEGIN!
made a jig to keep the fender geometry intact when I cut and pull out
left and right side are attached and in level and parallel plane
mark and cut
slide out. Notice how much I'm going to drop the top of the fender/ about 3/4"
Damn, I wish I had time to see it this week. Maybe next week Pipo. You're moving along quickly. Did you get your lathe yet?
Love that fender sliding jig, very nicely done. This build will bring new meaning to the term "Wide Body!"
This project just makes me smiiiiiile.
So cool, and love seeing the creativity!
The fixtures for the flare surgery is next level stuff...I dig it.
Thanks for all the nice comments. This weekend I plan on owering the fender tops about 1 inch and tying the tops of the fenders together. I plan on using the English wheel to give it that slight arch. Lets see how it goes. ........oh and mill came in today Looks like I'll be making my own suspension pieces.
UPDATE ON REAR FLARES
Mark to cut and slide down

Wow! That is going to look incredible!
I can't wait to see what these humongous STEEL rear fenders look like when completed. You are certainly a professional mad scientist. Very cool.
Tool Whore's the world over say, "Excellent use of the curvy template tool."
And by the way, it took me 531 days between when I started installing my flares until I fired my car for the first time (March 14, 2019 to August 26, 2020). I don't want to wait that long to see your car run so hopefully, you're a faster fabber than me!
Rudy, your car is gonna be wild! Can't wait to see it.
Damn, That sectioning of the rear flare is some damn fancy work! I didnt even see it the first time I looked at the pics! I thought it was just mockup!! The English wheel work is also fabulous!
Hey this is what I'm thinking for the rear. I'm open to suggestions.
I'm thinking of something like this. It's hard to illustrate it, but it won't look like horns or cat eyes. I'm thinking of 3d printing the louvers and then dipping in that paint that makes it look like carbon fiber. Where it attaches to the rea by the light will follow the contour of the fender
do nothing

I say you get the fender done, put a tire under it and see how it looks.
What other things are you doing to the rear that is non standard? Having these vents will help performance wise but its going to look really odd on this car if nothing else "modern" is being done besides wheels (And obviously the whole chassis but thats not visible from the outside).
DO you prefer form or function here?
There is a lot of trapped air in the back of a 914, but if for example you use a diffuser, there likely wont be much at all. And there is so little area behind the 914 rear tire that there wont be much air flowing into it.
If you are putting the vents in the rear of the flares, then put a boxster radiator in each one. That way you don't have to run the plumbing up front.
Rudy: Your car is going to make a Group 5 look tame by comparison...!
ON TO THE QUARTER PANEL
This is the direction that I'm going with to cut in the 1/4 panel to couch the air to water intercoolers as well as the cold air intakes. The cut will taper from o" depth at the door to 12" depth at the back. Notice how the top cut line is not level, it actually tapers up to follow that ever so slight rise in the 914 silhouette. The bottom line is parallel with the rocker panel.
By the way does anyone know how tall those Porsche side panel stickers are? The ones that go along the bottom of the door. I need a pair but in the negative. I'm thinking of dark metallic charcoal grey for the entirety of the car and then spraying the Porsche sticker logo in a Carrera silver along the bottom of the doors, like the stickers. I may continue that silver into the intake at the 1/4 panels. The rockers will be in black and they will follow the silhouette of the fenders.
Looking awesome!!
When you say 12" depth at the back is that measured off the OEM quarter panel or from the corresponding point on your flares? Asking since it looks like the heat exchangers will be in the wheel wells.
<b>@http://www.914world.com/bbs2/index.php?showuser=16669 </b> that's what I'm looking for. But I need the silver part to be open. I would use the sticker to spray the silver portion onto the car then pull the sticker off. How tall is the sticker? I need to know so that I don't cut the 1/4 panel too tall. By the way what is Chucky's. I google it and all I get is the chucky doll.
Hey Rudy
My side decals measure 3.00 tall
@http://www.914world.com/bbs2/index.php?showuser=15637

you should jack the wheel to stance position... :trophy:
That's looking really awesome!!! Keep at it!!!
Are you making a wood buck or two for the pass side?
I dropped by Rudy's yesterday and checked out his build. It's on another level entirely. His shop is a fabricators dream and what impresses me is he knows how to use all of that equipment. I watched him program a pattern on his computer with a CAD program then transfer it to the computer on his plasma cutting machine. I'm pretty sure it would take me about 11 years just to master what he did in under an hour. I think his decision to go back with the Audi drivetrain is a smart move even though the LS is a popular power plant. This build with the combination of the Audi drivetrain and super wide trac and huge tires should be a rocket off the line and insane through the turns.
REAR FENDERS ARE PRETTY COMPLETE NOW. RUBBER COMING IN TOMORROW. JOPING TO START FRONT FENDERS THIS WEEKEND
Hey does anyone have front portions of the front fenders available? I need the portion where the turn signal bucket goes in. I want to widen the front turn signal bucket about 1" so that I can stick some LED's in there. Since I will be working the front fenders this weekend.......timing will be just right.
Totally awesome build. Huge props.
I have to ask... is that driver's side cage tube gonna be a head knocker? Seems low and right in line with a helmet. Sorry, don't mean to be negative at all, pic just begged the question.
Outstanding metalwork.
Wow. This makes the rockin' world go round.
So Sexy!!
That's a spicy meatball!
Tirerrific !!!
WIDE you pick those tires?
Your traction makes me envious... Can't wait to see the fronts go on!
Moved on to the front. Had to compress the front wheel and turn both directions to make sure that the wheel would not rub. Also, the shot of the rear is still with 1" of uptravel before it bottoms out. I would like the at rest position to be 1" lower. I want 2" of uptravel.
1" uptravel left
Compress and check for rubbing
Cut out front half of fender outside face to widen the turn signal for LED projectors to fit in. Did what @JEff_Hail said to do since I couldn't get an outside skin in time, and his idea turned out to be better.
widened 1" and insert LED Projectors in here. This also makes it so that the 3" extension on the front fenders (total of 5") doesn't look weird. Yes a jig for fronts as well.
I think that I will have the drivers side front fender complete this weekend. The passenger side will be done in half the time. I spend a lot of time figuring and measuring but that's already known so it will be quick for fronts (4 hours or so).
Damn, your moving right along Rudy.
Rudy's 914 Got the meats like Arby's & the deep dish like a Chicago pie
You win the widest 914 award hands down, I love it !
DAMN! Can you just clear coat your car and call her the Stiched Bitch!?
@maltese_falcon are you serious.......I had the best deep dish pizza ever at Gino's East in Chicago.....never had another like it, especially their sausage it's like no other. I'll be in Calabassas visiting family this weekend and will definitely stop by on the way. Thanks for the heads up.......even though it's not 914 related
@Jeff_Hail I have a crown in the fender but it's along where it ties into the face of the 916 flare. I wheeled it along the edge then put it in a die to really turn the edge See photos. Are you saying to lift the middle of the flare? By the way, it's funny that you mention the louvers since I've been mulling that around for the front fenders. That will release air from the radiators.
REDRUM
Attached image(s)
@http://www.914world.com/bbs2/index.php?showuser=2744 OK I see what you did there. It's what Jeff Hail was talking about...the RSR look. Looks good but it's not the directions I'm going in.
So this is what the fronts are looking like. I decided to print up a louver system for the rear of the front fender and cover it in carbon fiber. It will be very recessed into the fender and will accentuate a curve coming out of the fender to mirror the 1/4 panel.
I await your vision ,, I just saw an opportunity to show REDRUM , built in SoCal early 80's...sitting in Utah..
Okay ah, I get the design placement but this would rule me out of sitting in either side.
I sold a 1994 M edition Miata jut because my head would hit the top bow, I just did not fit. Knowing that in my 914 with the seat cushion in place, my head could hit the rear hoop. in my old race car. The tie in bars while going into the tie ins for the angles and rear bars, that would be very close to my head.
I'm a bit bummed by this for two reasons, one I want you to keep your head on your shoulders with out adding a plate to cover the crushed area, and if you do fit with plenty of clearance, I will never be able to ride in this sweet build because I would have to remove my head and place it in my lap. Thus removing my enthusiasm for the ride, and creating quite a biological cleanup for you.
Please just check your fit before you become a crash test dummy.
Is there enough room in the front fender to turn the wheel?
@http://www.914world.com/bbs2/index.php?showuser=2388 "I will never be able to ride in this sweet build because I would have to remove my head and place it in my lap. Thus removing my enthusiasm for the ride, and creating quite a biological cleanup for you".......... you're crazy man! Yes, those bars will be gone. If you look closely they are only tacked on.
@http://www.914world.com/bbs2/index.php?showuser=3387 if you look closely the lip is tacked on and I will adjust as needed when I put back on the ground and compress with about 600# of weights. Don't worry at the end of the day it will not rub cause I can and
Looks good.
So badass...
Thanks guys.
I semi completed all the fenders. I need to finish the rocker panels before I finish welding the fenders. I tried different bends to get to the final depth that I wanted. The final rocker will have a rubber strip and fastened like Marv's 6 project. Here are some update pictures.
This is how the the front wide-body is looking
bend cut try again
getting closer
this one ( 1.5" radius and offset along lower lip or
this one ( 2" radius and no offset along lower lip) I think the previous one was starting to
look like crown molding
Well done Rudy. What gauge are you using for the rocker panels? Also, can you describe/show what you're using to shape/bend the metal?
Awesome - keep the updates coming!
-Steve
More update on the rocker panels. I just need to finish the ends.....that's easy. The hard part was getting these things to mount sturdily on the car and make them removable and allow conduits to pass through. I designed to give me flexibility to run whatever conduits I want in the rockers or the longs.
You're having entirely too much fun Rudy. You may not want to go back to work after this. I was going to come by but I spent the last "2" days re-entering every invoice, deposit and pay check for the last 6 weeks. Friggin computers. We're leaving for TX to see the grandkids I won't get by for a couple of more weeks now. Hopefully I'll be back in time for the first drive! BTW, it's looking really good Rudy.
Art and talent. Well done! You inspire all of us. Thanks for sharing!
I love the progress shots Rudy!
For me the slowest part is always resizing images. If that's your issue, I highly recommend installing ImageRisizer (now part of MS PowerToys). Then it's just a right click to resize and you're good to load.

Side skirt metal work is done. Took 15 Riv nuts to install each side. Next is finish welding the fenders then on to the rear hood and metal duck spoiler.
Very cool
I, too, really enjoy seeing how you're planning, fabricating and executing. Please keep up the great work, and thanks for sharing!!!
It's good to hear from the peeps that are interested. It seems that the nature of this beast is such that it has so much non-914 content that it automatically excludes an entire segment that would otherwise engage if it were something more of things that they would want to do on their car. At this point I'm adding pictures more for record keeping. Next step is to finish welding the flares. Hopefully I will start building the all metal duck tail (different from what is out there right now), cut up the rear hood to increase heat extraction, simultaneously lighten and stiffen the rear hood and build a trick mechanism to tilt the whole thing back.
@http://www.914world.com/bbs2/index.php?showuser=8624 thanks man!
You are very savvy with the metal !
I am enjoying the seeing the build and your impressive skills. Can’t wait to see this beast in person someday! I am guessing documenting it helps with the motivation also so keep it up
I just chatted with Rudy about his plans for this car. Incredible stuff, to say the least. I'm hoping to stop by his shop in July when I'm down in his area to help my daughter and her husband move from Oceanside back to SLO County. Keep up the great work Rudy!
Thanks Geoff @http://www.914world.com/bbs2/index.php?showuser=8624 I finished welding the fenders and am now buttoning up some minor issues before I prime and add "minor" amounts of, dare I say it.............BONDO.
I am moving on to the rear hood and duck tail, then suspension and front hood. At that point I will have a roller.......again!
As a side-note-flirtation-with-another-bastard idea, I heard and rode in Kent's car @http://www.914world.com/bbs2/index.php?showuser=9964 and I got the bug to install a Twin Turbo Subaru Flat 6 G33 motor. That was summarily shot down once I discovered that no one makes an adapter anymore. The last time it was made, it was by Precision Chassis and for $2,200 + Clutch.......ouch! I understand that the process to mate the G33 to Cayman S is not easy. Someone suggested, cough cough Kent, then go with Subaru STI 6 speed. Then it will be a match made in heaven. However, I did a lil bit of homework and realized that those transaxles will not support big power as a front drive only. The ring and pinion is something like 2" less than the Cayman S........so I'M STICKING WITH 2.7 AUDI AND CAYMAN S. KENT YOU ARE NOT ALLOWED TO BRING ANYMORE JEZZEBELS IN MY SHOP. I NEED TO FINISH THIS THING!!!!
THE CAR SHALL HENCETOFORTH BE NAMED 914RS4
Oh sure, blame it on me. You just got caught up in my exhaust's sound.
Ahh You stole the name I've been tossing around in my head for a couple years
It suits your car better though
Glad to see your still on the Audi kick! If you were local I'd give you a ride..
Remind me at WCR!!
This will be the badge
This is one of my favorite builds. I love builds that involve a lot of fabrication and creative engine, transmission and suspension swaps.
I think I learned the most from these kind of builds. I enjoy the regular stock restoration and six conversions too.

Very cool, can't wait for the next installment.
kind of has a 959ish look to it with the thresholds out over the rockers from fender to fender like that , very cool!
Looking good Rudy. I haven’t seen it for awhile. Looks like I need to get my butt by there soon and check it out.
Rudy -
That.
Looks.
EPIC!!!!
Wow. And having done a bit of fabrication, I can appreciate the time and effort you have in your build. And not just the actual fab work. I'd bet you have at least 2-3 times that in head-scratching and what-if'ing ahead of putting hands to metal. Not to mention the inevitable "Oh boy, I wonder if this will even work?!?"
Absolutely LOVE your ambition and execution. I can't wait to see your creation in person.
Keep up the great work!
SWEEEEEEEEET
Can you share any details on the headlights you are using...?
Oh and I don't care if they are legal or not. However, they are technically being used as fog lights for which they are legal.
I think that they would fit in a stock 914. If they do fit, I may make a run of headlight buckets and lenses if anyone is interested. They will bolt into the 914 fenders.
I'd be interested! Plan on not doing popups and would love to put the lights up into the fenders.
They seem long to fit in the stock headlight bucket, no?
Very cool nonetheless!
Yes,
I will be making a custom headlight bucket. There's really nothing out there that can be easily modified to hold those LEDs.
I was finally able to get a coat of epoxy primer on the fenders. The epoxy is supposed to seal the work so that water can't get to the metal and bodywork. Then I will shoot with 3 coats of high fill 2 part primer. Then block sand and get all mini waves out. I'm very happy with the body work. By the way, the primer I'm using is SPI........amazing stuff.
It's all made in the USA, and their epoxy primer happens to be sandable.

Rudy...your skills could put a Pebble Beach coachbuilder out of business
Thank you for the compliment but if they saw how the sausage was made in the back of the kitchen, they'd throw me out with a swift kick. Some of those guys are true masters..........I have to use a small amount of bondo. But I suspect that all of the painted cars have a small amount of bondo or at least high build primer.
Just painted fenders with high build primer.

Wow - looks really narrow in primer. Almost stock.

Front has been neglected so here you go.

No words. Well, other than these.
This build is phenomenal Rudy. Wow. Love the outlets on the fenders, it does indeed have a 959 vibe happening there. Very cool.
Thanks guys. Positive comments keep us going. If there was no one to share your work with it would not be as rewarding. Going to be out for a while. I’m in the middle of a fight with COVID. I’ve been completely exhausted for 5 days now. Lost smell and taste. No energy to walk to the restroom. Have to muster all I have to get up. Today odd the first day that I felt a change in the right direction. For all my brothers out there say a prayer for me.
Prayer sent, hope you are 100% real soon. God knows the world needs someone that can create a 914 Salvador Dali Edition.
Prayers for a speedy recovery!
I just went through a radical prostatectomy last Thursday, from which I'm still recovering. Needless to say, there's no 914 activity over here.
Andys
Prayer sent, hope you are 100% soon..
Damn Rudy, I almost stopped by there last Friday but I was driving the red 914 and it was getting hot outside so I went straight home. Glad that I went home instead now. I thought you already had covid several months back. Are you vaccinated? Is this the Variant? Regardless prayers sent, God Speed and if there is anything I can do for you - from a safe distance - LMK.
Get better soon so you can get back on that 914. Nothing as satisfying as getting some primer on it - big milestone.
Just an amazing build. I hope you get well soon and get back to work on this incredible car. Rest and get well.
Drink lots of water and keep the positive attitude! Get better soon buddy!
Rudy - You take care and get well soon!
Take care of you for now...the rest of us will have to suffer through with your previous posts for inspiration and vision! Get well soon bud!
Hang in there dude!
@http://www.914world.com/bbs2/index.php?showuser=15637
You doin OK buddy? Lots of us are concerned that you havent logged in since the 10th!
I just caught up on all of this. This build is friggin' BANANAS.
B. A. N. A. N. A. S.
Hey guys wow I barely made it. Had a real life and death struggle with Covid. So many were praying thank you thank you thank you. I had a direct encounter with King Jesus. I had given up the fight and was ready to die. I had been fighting for 10 days, had no appetite lost at least 15 lbs in 10 days. But God had other plans for me. Had a vision where King Jesus pulled out from the lineup. May sound weird to some but I can’t deny what I saw and how King Jesus saved me. This happened on Tuesday morning. From that point on my full appetite came back and I’ve just been regaining my strength. I’m so glad to be back.
Even Jesus wants to see your build finished. Welcome back Pipo.
Wow, glad you pulled through. It affects people so differently and sounds like you got lucky. Glad you are getting better.
Good to hear your on the mend.
Rudy
Thank you for the update. We all need you, but most importantly your family does too. Looking forward to seeing you back on your feet enjoying what you do....
Just FYI, you're not alone. I have a family member with long haul Covid..not fun
Stay strong my friend
Oscar
Rudy, Thank you for taking the time to let us know how your doing! Were all praying for you!
Rudy, thank God you pulled through!
Andys
Thanks everyone! You guys are all a bunch of good peeeepz. Thank you for all your prayers....and I truly mean that. I'm getting back at it as of today. Will have an update soon on the cantilever suspension.
Just checking in to see how you're feeling! Hope you have the energy for the build.
Hey @Netspeed thank you for asking. I do have the energy and have been working on the car. I would like more time but I was out almost a month from Covid and had a lot of work to catch up on. I completed the fenders though, blocked and primed inside and out, the floor is primed inside and out. I’m now moving on to the suspension pieces. have them engineered now I need to install my new mill and Lathe.

Rudy your car is as sick as they get.
You must stay well.
Best wishes and prayers.
Beautiful concept and execution.
An inspiration.

QUICK UPDATE:
Seats came in. Posted a couple of pictures for comparison. The Recaros use std 914 seat sliders. They slide and recline as well.
The suspension pieces are engineered and are being machined.
