Well its still subaru powered, but ive made the swap over to the EZ30R H6 3.0 Subaru motor Read on

Hey Guys I finally got some time and the motivation to start working on my project car again. I started it a few years ago but, got side tracked on a few other project but I have decided to come back to it and finish it.

I all started 3-4 years ago when i got my first subaru wrx and decided i loved the power plant and thought what better way to add a lot of power to a light car. So i started with getting a twin turbo ej20 subaru engine from japan. I also bought the kennedy engineering adapter kit. I worked on the car for awhile, then got busy working on other project and kind of abanoned it. But no im back working on it about 5 nights a week.

But lucky I did take a break from it cause i decided to make to big changes to the car( since i can afford them now. Im going to use the stock subaru trans, with a bremar 2wd kit. Im going to use big brakes all the way around, i have some big reds for the front, and im goin to do the rear also. Car is getting a full cage, and all longs and suspension pickups are going to be plated and reinforced. And i decided to swap over to the single turbo set up for simplicity of tuning, and more maximum power output. ( im eventually swaping in a built 2.5 STI engine)

So i thought id start a thread to show my progress on my car, and will glady answer any questions along the way if anyone is looking to do a similar swap. Seems like the subaru conversion has gained a lot of popularity since i started my project quiet awhile ago.

Started working on it about one and a half weeks ago, and so far got my interior stripped out, and gonna pick up my material for my cage next week. I got my transmission mounts fabricated, and my engine mount fabricated, and now im working on reinforcing the shock tower and such where my engine mount attaches to. Here's some picks of my progress hope you all enjoy


Here the engine sitting in the car






Transmission mounts, there not done yet still gotta cap all the ends on them and powder coat them and such





My exhasut header and big uppipe






Engine mount ill show some pics of it installed later its out right now as im tig welding it up right now




My stripped out interior, getting ready to prep it to plate the longs and start my cage

Very cool. Keep us posted on your prgress.

Posted by: scotty914 Jun 15 2008, 09:18 PM

that engine mount design looks like i have seen it before

and on cutting the rear trunk out.... wow

i have thought about upgrading mine to a suby tranny, but first i need to get it back on the road

Posted by: rick 918-S Jun 15 2008, 10:48 PM

SCOTTY! Ya looks kind of like your mount. You were the pioneer. Before the Vegas guys did theirs.

I would sleeve those mount bolts or they will start to crush the tubing and either fall out of shear off. Oh and use grade 8's.

Posted by: TwinTurbo914 Jun 16 2008, 01:15 PM

Yah Im going to sleeve and cap everything when im done with them, just wanted to get the rough construction done first. Im gonna powder coat them also.

Worked on the Car a little bit more this weekend, i stripped all the insulation/sound deadening from the floor, and worked on getting the dash out, im gonna soda blast the whole interior of the car, before i start work on my cage, and boxing my longs.

I also started work on mocking up my intercooler setup. I'll post some more pics soon.

Any twin turbo parts that you want to get rid of? I got a jdm motor as well but I'm missing parts .....

Posted by: TwinTurbo914 Jul 7 2008, 05:51 PM

Sorry no Parts, they are all long gone. I sold the whole turbo set up, the twin turbo setup is know to have an inherant dead spot when the second turbo comes in at about 3500rpm. Swap over to a single turbo, much easier for future tuning (like a larger turbo) and easier engine packaging clearance wise. Let me know if you need any parts for a single turbo system i got some stuff laying around.



I have been hard at work on my car, i got the whole interior stripped out, and all the floor insulation pulled up. And i got a chassis strenghtening kit, and i punched all the holes in the pieces good thing i had a sheet metal hole puncher ( I hate drilling holes LOL). So this week im gonna soda blast the complete interior of the car to have it all nice and clean and to bare metal for when i make all the plating for the longs. And im gonna soda blast my inner fender wells and my engine compartment. Ill get some new pics up in the next day or so of my progress so far

Posted by: TwinTurbo914 Jan 8 2009, 10:48 AM

Well i have not given any updates lately as things have just been crazy lately, work has been very busy and i moved into a new house, but i have been working on the car off and on as i get time. I have basically all the plating made up for the interior of the car for the longs, so i just have to soda blast the interior and drill all the holes in my plating and weld everything in, then i can move on to the next part of the project.

I have made a Major decision to change the power plant Slightly on my project. Im Gonna sell the subie 4 cyl, and im gonna buy a EZ30R subie Six Cylinder. They are a 3.0 flat six, and its only 1.5" longer than the subie four, plus they have variable valve timing and variable valve lift and there 250HP stock N/A. So More Cubes, and more of that porsche sound. Oh and its still gonna be turbo charged possibly twin turbo. . Ill update soon with some pics, as everything has calmed down and im able to work on the car a few nights a week now.

Stay tuned more to come

LOOKIN GOOD.. I just did a top end for a Subie, I dream a a 4 valve turbo aircooled 914..

Posted by: EVILGENIUS13 Jan 9 2009, 03:56 AM

Some guys in australia have put subie heads on type 1 and type 4's. The bore centers are the same.

Posted by: TwinTurbo914 Jan 12 2009, 10:51 AM

Well I worked on cleaning up in the shop a little this weekend, my dad is not exactly the tidiest of workers, haha. But anyways I was able to clear enough space to get the car outside so i could soda blast the interior and part of the engine compartment. I was such a gorgeous day, almost 60 degrees and sunny. Now I can get all my boxing welded onto the rails. Ill update tomorrow with some pics.

Posted by: TwinTurbo914 Jan 13 2009, 11:10 AM

Well i have Been working away at the car when ever i get a chance. And i have made the final decision that im Gonna change over to the subaru 3.0 Six so if any one is looking for a Good EJ20 Subie engine, i have one along with a good stainless header and uppipe. I also have a kennedy adapter and clutch for the 914 transaxle, as im using the subie trans. Lemme know if anyone is interested.

Heres a few pics of the Interior and engine compartment. I got most of the interior blasted and some of the engine compartment done. I'll probably do more this weekend. I just gonna finish removing some of the seam sealer.





















Last night I got my girl friend Erin in the shop with me, she wanted to learn how to weld, she's been bugging me since the sema show when she got to try a demo welder at the Lincoln booth. So hopefully she gets hooked and will want to help me on my projects, lol.






Here's a Pic of the hell hole area, it looks really good very few spots that had rusted thru



This week ill finish stripping the seam sealer, and then work on prepping the plating i made for the longs, and drill all the holes in them, and them get them welded in. Them ill work on making the pieces to box in the rails in the engine compartment. Stay tuned more to come

Posted by: quadracerx Jan 13 2009, 09:34 PM

[b]DUDE....your like liv'in the dream...LOL Hot girlfriend who wants to learn to weld and help with your projects....Keep her at all costs....Just curious on a couple things...keeping the Subaru trans from the six? Love to know how your gonna adapt that to the suspension....2nd not that I could afford it but what is the Subaru EJ worth?

Thanks...and keep up the great work...

Steve

Posted by: charliew Jan 13 2009, 09:46 PM

Put the suby in that Izetta? isetta?

Posted by: turnaround89 Jan 13 2009, 10:02 PM

Nice work. Very cool, wish my hell hole looked like that, mine was way worse.

Can ask why your able to cut out the area in the trunk? I understand that it will help with engine fitting, but doesn't that part of the trunk add some structure to the car, or maybe it doesn't add any?

Posted by: ChrisNPDrider Jan 13 2009, 10:13 PM

Yes, that trunk section braces between shock towers...something besides the horzontal sheetmetal should be there to avoid flex.

Dude - where in NorCal are you at? My 914 is in a garage in El Cerrito and I currently reside in Woodacre - both near SF Bay. My daily driver is a Subaru, and if I ever get in a wreck, guess where that motor is going?

I love watching projects like this! Keep it up!

Posted by: TwinTurbo914 Jan 14 2009, 10:33 AM

Yah she is Definatly a Keeper, she has been putting up with me for over three years now. She will help me when ever i need help as long as I ask nicely. Haha.

Yes im keeping the subaru Trans when i transfer over to the Six, i already have the Transaxle mount fabricated, i just have to finish them up ( sleave the bolt hole and box the ends). Further up in the thread i have some pics of them. The only major thing is i have to either have custom axle's made or some adapter flanges made to go from the subaru stub axle to the 914 axle.

I would like to get about $800 for the engine, i have all the acessories and brackets for it. I also have the turbo header and turbo up pipe for it i would like about $400 for them. And i even have a Kennedy adapter and clutch kit to go from the Subie engine to the 901 transaxle, i gotta check what i paid for it. I only bolted it up once, then changed to the subie trans. But I will take less then I paid for it of course.




Not quite enough room in the Isetta to do a Subie Swap:D, that one is my dad's project, he's doing a full resto on it.

Posted by: TwinTurbo914 Jan 14 2009, 10:44 AM

Well I cut the trunk for a couple of reasons, One it made it alot eaiser to fit the engine. But it would kit no problem with the trunk wall, it would just need to be notched a little for the turbo on the passenger side. and two the car is gonna get a full cage with full trunk bracing and a the cage will completely tie the shock towers together. More on that to come, once i get longs plated and the engine compartment frame rails plated.




I live Near Lake Camanche in a small town called Valley Springs. Im about 20 miles East of Lodi if you know where that is

Posted by: charliew Jan 14 2009, 12:36 PM

Do you know about the suby to bus adapters from porscharu? There are some people getting together another order for them. They get a price break on ten sets or more. I have them and they are very nice. The bus is a larger diameter cv. I am going with 911 axle stubs and they are the same size as the bus cvs so it will be bus on both ends but you can use 914 on the outer by adding a thin washer type spacer from what I remember, the 914 cv is thinner. Paint fumes cloud my memory a little. I am glad you are going to a suby six, I really like the six sound better especially if it's spinning about 7k and there is all that wasted space in front of the four. Seems like I remember the 6 hangs down a lot more than the 4 though. I made a 8qt pan with parts from kennedy and used some swinging gates from a speedway sbc cheater kit for my suby 4 and it's only about 4.5 deep. I also modified the stainless header to be the same depth for the ground clearance. The six is a lot different though.

Posted by: TwinTurbo914 Jan 14 2009, 01:33 PM

Do you have a list of people that are getting together i contacted Porscharu about six months ago and expressed my interest and told him to let me know if there was gonna be another order but i have not heard anything since. And info your be awsome

Posted by: TwinTurbo914 Jan 22 2009, 06:40 PM

Im making good progress on the interior reinforcement, should be all welded up by this weekend. Ill post some pics next week after i get it all welded up.

I also have some subaru conversion parts forsale in the classified section heres a link http://www.914world.com/bbs2/index.php?showtopic=91956

I also just got a new 914, its a 914-6 Race Car with full flares and no targa bar. It's pretty wild looking, it's multi color. I think its a 2.7 with mechanical injection. Ill post some pics of it soon

Posted by: cymaster007 Jan 22 2009, 08:43 PM

What do you have planned for your radiator/cooling set up?

Posted by: jd74914 Jan 22 2009, 10:08 PM

I can't wait to see the pics.

Posted by: TwinTurbo914 Jan 23 2009, 10:40 AM

Im Going to Run a front mounted Radiator, that im going to mount up in front between the headlights, and run hard lines back to the engine compartment. But i have not made up my mind yet on where im gonna run the coolant line, I have a few idea's but nothing is set in stone yet.

Posted by: TwinTurbo914 Jan 29 2009, 10:38 AM

Well Im still plugging away at the car, the interior bracing is basically done, other than being welded up, well and other than the roll cage, but thats a whole other phase of the project. And now im working on the bracing that goes on the engine compartment rails. I already have the GT style kit that attaches to the rails in the rear fender wells, i just have to strip the under coating and weld them in. So ill be doing that as soon as i finish up in the engine compartment, which hopefully should be sometime in the next week.

Posted by: TwinTurbo914 Mar 3 2009, 02:58 PM

Hey everyone sorry for no updates, but I haven't been able to work on my car in awhile. I had a wonderful opportunity come along to open up a second location of my business and I had to jump at it. But needless to say work on my car has suffered. I've been working 70-80 hours a week and 7 days a week. So juggling work and trying to spend what little time I get with my girlfriend. Thank goodness she is very understanding .

But the brunt of the work of setting up the shop is almost done and things will get back to normal soon enough. And as soon as I get my taxes back ill be buying the EZ30R Subie Six im putting in the car, so ill be sure to get some pics of that up soon.

Stay Tuned There will be More to come soon.

-Donny

Posted by: MZM Apr 5 2009, 11:56 PM

Happy for you that you have a growing business these days! Still, got any updates? Where are you sourcing the EZ30? Why not the EZ36?

Mike M

Posted by: Zaney Apr 6 2009, 10:08 AM

I vote for an EZ36 too! I believe they are roughly the same size but, with more juice! Plus, I have heard of Crawford perfomance working on turbo bits for the EZ36 as well.

Posted by: TwinTurbo914 Apr 6 2009, 01:21 PM

From the research i've done the ez36 has offset rods on them and currently no one is making an aftermarket rods for it which they make for the ez30r. Which im gonna need since i dont plan on driving the car easy.

Posted by: charliew Apr 7 2009, 12:25 PM

If I where you I would check on the axle adapters.

Posted by: TwinTurbo914 May 4 2009, 01:18 PM

Finally got to work on the car a little bit this weekend, did some more welding on my chassis boxing plates. And got most of what was left of the rear floor cut out. I also found a radiator at the pomona swapmeet the other weekend, its nice and short so i can have it sit straight up in between the headlights, plus it already had a custom aluminum shroud on it with two fans, it fits almost perfect. Ill post some new pics soon. Things have been starting to get back to normal, not working quite as much now as the new shop has gotten busy enough to hire some help now, but i am still working 6 days a week.

But i promise a new update with pics will be soon

Posted by: TwinTurbo914 Jun 29 2009, 11:16 AM

Sorry for being so slow on updating on the progress, but my new shop has been taking up most of my time, im working like 12-14 hours a day six days a week, so i only have a few hour a week on sunday to work on the car. But i cant complain to much as i took a huge risk of opening up a new business in one of the worst economies ever, and well so far business is great and has exceeded my expectations. Anyways back to the car, I order the axle adapters from porcharu and ill hopefully be getting my engine in the next month or so. My source has a container coming in in about 3 weeks. So thats when the fun will really start.

So stay tuned more to come

Posted by: TwinTurbo914 Jul 13 2009, 03:04 PM

Well i have been making some progress on the car, last night i have up some mounts, to attach the body to my rotisserie so I have finish up some of my welding and clean everything up underneath of the car.

I should have my engine by the end of the month. And I found a set of exhaust flanges, Outfront motorsports had them in stock, they normally carry them in mild steel but they have an extra set of stainless steel in stock that they had done, both flanges shipped to my door were $59, and there 1/2" thick, i though they were a bargain. I have my exhaust kit on order, which is a set of assorted u-bends, and 90's and such so i can start fabing up my headers, But i have to get my collectors on order , and im gonna buy one turbo for now so i can fab everything(icant afford to buy both of them now. They are pretty pricey, they are the turbonetics GTK-350 ceramic ball bearing turbos. Ill post some pics of my flanges and the car on the rotisserie in the next day or so.

Im making decent progress, and should get a bunch done over the next two weeks, the girlfriend is on vacation for two weeks, so I wont get yelled at to spend time with her instead of working on my car

Posted by: gopack Jul 13 2009, 03:21 PM

soOOOO very cool! keep it up and you may inspire others! then you will have the burden of being a role model!

Posted by: RiqueMar Jul 13 2009, 05:15 PM

Haha, weird. We are both 914 owners. We both live in CA. We both have GF's named Erin. They both kinda help with the cars.

Posted by: TwinTurbo914 Jul 13 2009, 05:34 PM

Both of our car are orange also LOL

Posted by: ghuff Jul 13 2009, 06:10 PM

This should turn out to be a lot of fun. Sheetmetal work looks good so far, the welds look good.

Posted by: TwinTurbo914 Jul 14 2009, 10:31 AM

Well here as promised, a little late the never are a few pictures.

Here is my new custom front and rear push bumpers, haha just kidding it's the mounts I made to go to my rotisserie








Heres a few more shot on my sheetmetal work of my chassis strenghtening and I just started installing my GT Kit, the rotisserie will be nice for finishing that. I finally got my dad's Isetta off of it, so my car should be on it in the next new days







These are my new header flanges I just got the other day from outfront motorsports, there 1/2" thick and stainless

Posted by: TwinTurbo914 Aug 11 2009, 11:29 AM

Well im slowly making progress, here a few pics from a few weeks ago, i have got a few more things done since. Like made a few new pieces of my reinforcements, and this weekend i did a little sand blasting in the engine compartment to get rid of the rust. Im making progress slowly, but surely. Engine should be here in another couple of weeks, ill post some more pics soon.

Got it up on the rotisserie a couple of weeks ago, much easier to work on now, and made it way easier when i did some sandblasting this weekend

Posted by: charliew Aug 13 2009, 12:16 AM

Boy you trust the tranny crossmember way more than I would have for the rear support on the rotisserie course with the floor cut out the back panel hasn't got much left for support either..

Posted by: TwinTurbo914 Aug 17 2009, 01:13 PM

It's really solid with all the reinforcements i have done to the chassis, i wouldn't have done it that way to a stocker.

Little update on my car, worked on it all day yesterday, did some more sheet metal work on the outer rear frame rails, got quite a few pieces made, so im almost done with that, which is great be cause im getting bored with that, but i should be getting my ez30r hopefully this coming weekend. Im taking my GF to magic mountain for her birthday, and will pick up the engine if they are in stock, gruppe-s just happens to only be an hour drive from magic mountain, but hey she wanted to go to magic mountain, so it worked out great. So hopefully I should have some picks of the engine next week. (keeping my fingers crossed). And well if they dont get the engine till next week, well i guess all the hotels are gonna be sold out and we have to delay the trip another week

Posted by: Numbchux Sep 4 2009, 12:19 AM

very cool! what do you plan to run for management? stock ECU won't work in a porsche due to immobilizer issues, so you'll be running a standalone of some sort. I know Hydra can run the EZ30DR, but the AVCS and AVLS control is open loop. the new Link can control them all with closed-loop mapping, but that setup is extremely expensive.



I bought an EZ30DR shortblock about a month ago.....haven't decided what to do with it. putting it in a 914 has crossed my mind....

Posted by: TwinTurbo914 Sep 4 2009, 10:59 AM

You posted your engine as ez30dr, there is actually two different engines the 01-04 engine which has no variable valve lift or variable cam timing, and its called the ez30d they also only have one exhaust port per head. The engine im using is the ez30r which has the cam lift and valve timing, and three exhaust ports on each head. The ez30r was made from 05-07, then they changed to the ez36r which isnt any good for performance because of the offset connecting rods.

Both of the ez30's are awsome engines with tons of performance potential, outfront motorsports builds them for dune buggys and has made over 1100 HP with a stock block with a closed deck, and a stock crankshaft. Cant wait to get mine going.

Im looking into the link its not that much more expensive then the hydra. But i have quite awhile before i have to worry about Engine management.

But have been making progress on the car just nothing to exciting to show any pics of

Posted by: budman5201 Sep 4 2009, 02:49 PM

NOPE I can get you a Link for $1100 shipped to you. For an awesome stand alone thats great!

[/quote]

That may be for the four cylinder, but i thought it was around $2100 for the G4 for the ez30 but it been awhile since I checked but i may be wrong

Posted by: DBCooper Sep 4 2009, 03:26 PM

I think the base G4 box only has four ignition drivers, but that just means you'd run it with wasted spark for six and eight cylinder motors.

I haven't looked at the Link in a while either, but it may be time for another one.

Posted by: TwinTurbo914 Sep 4 2009, 04:06 PM

Haven't done a ton of research on the G4 but I know there is a few guys running the ez30r's in some subie's with the variable valve lift and cam timing working under closed loop. But dont know about the ignition drivers. But the link is probably what im going to run.

Yep your exactly correct. The $1100 price is for the G4 Link Storm ECU ( what i am running) it is sequential up to 4 cylinders then you have to run either batch or waster spark for 6-8 cylinders (1 mpg difference and power almost the same.I have had both computers) I believe the STORM also has cam control capabilities. it lists this under features on the Linkecu website

-Precision closed loop cam control (four cam, independent control)



The G4 Link EXTREME has up to 8 cylinders sequential possibilities and GOBBBS of other functions. (youll prob never use) But it runs $1600 (My Price.)

Check out their website linkecu.com it lists almost anything you want to know about those computers. I love them!

Posted by: Numbchux Sep 4 2009, 09:54 PM

common mistake, the actual engine code is EZ30DR. the '05+ one with AVCS and AVLS is the DR. the motor I have came out of an '05 Tribeca. the 3.6 is a DR as well, but it has AVCS on both intake and exhaust cams. too bad about those rods though.





anyway, sweet project. I have worked with a few Links on various swaps, and have an older one (v4 Link 1) that I plan to use on my supercharged EJ22e (which might find it's way into a 914....). I would highly recommend going that route.




budman, are you a Link dealer? I need a ComLink for my ECU....

Posted by: charliew Sep 12 2009, 10:21 AM

I will follow this my son and I are looking at standalones mainly because the drive by wire is a bear to get right with rr. And I like the idea of getting rid of all the excess wires of the oem ecus but at a pretty steep price.

Posted by: budman5201 Sep 13 2009, 12:24 PM

Yep I have a comlink. Can you take a picture of your input port so i can make sure its the correct one for your application?

Posted by: Numbchux Sep 13 2009, 03:11 PM

sending a pm so I don't clutter this thread anymore....Thanks!

Posted by: TwinTurbo914 Sep 28 2009, 01:46 PM

Well not to much new going on still plugging away at the car, just lots of grinding. Im cleaning up all the boxing and welding i did in the engine compartment and the interior. Hey I gotta make everything look pretty. Still got quite a bit to do though.

I started this weekend by working on laying out the roll cage. I should have my tubing in the next few days. And I'll probably start working on that this weekend.

But the exciting news is at least for me, haha, Is my engine is in, but its about 450 miles away. But it could not have had better timing as my parents are going on a cruise this week and they come back on Monday, and they leave out of San Diego so that means they are passing right by the company that i bought my engine from. So they are gonna pick it up for me a save me a weekend of driving.

I cant wait to get it, it the one thing really holding me up right now

Posted by: TwinTurbo914 Oct 14 2009, 10:57 AM

Well started on the Rollcage this last weekend and got quite a bit done. Here's a few pics to show some progress, hopefully should be able to work on it some more this weekend. Im still waiting on the engine, but thats a whole other depressing story, but it should be here soon.

Enjoy the pics

Posted by: TwinTurbo914 Dec 7 2009, 11:24 AM

Well Great news today, I finally got my engine. I picked it up from Gruppe-S this weekend, worked out perfectly as they are open on saturday, and we were going down to Socal for the Pomona swapmeet anyways. And then we were also able to go to the LA Autoshow saturday also. Had a great weekend down there and now the real fun starts now that I finally got my engine.

Ill get some pics of it as soon as I can get it unloaded out of the truck.

Posted by: TwinTurbo914 Dec 9 2009, 10:45 AM

Well Finally Got the engine out of my truck yesterday, my dad bought a big vertical metal cutting band saw at the swapmeet this weekend, so it had my engine trapped in my truck. So I had him help me unload everything yesterday. So I was able to unload the engine and I just had to get it into my engine bay, ive been waiting for this moment for ever. I used my existing transaxle mounts and used some leveling stands for the engine and got it mocked up last night. And it fits and looks awsome.

Unfortunatly my engine mount bar for the 4 cylinder subie isn't going to work so im going to make all new mounts, because im gonna give the mounts to one of my employee's that is gonna buy my 4 cylinder subie engine setup to do a swap on his 914.

The engine fits great with plenty of room all around, and just looks really cool ( will look even better once I get both turbo's hanging off of it ). One thing I was a little worried about is oil pan clearance, but that looks to be like its not gonna be a problem. I have the car on the ground and setting pretty low and I have about 6" minimum ground clearance with the oil pan.

Ill Post some more pic soon I gotta get my camera back from my GF. I just snapped these with my phone because I couldn't wait.

Posted by: strawman Dec 10 2009, 12:13 AM

Sweet, a big block Suby!

I'm kinda surprised the engine bar doesn't fit -- for some reason, I thought the Suby six-cylinder engine and the four-bangers shared engine mounts... I guess the EZ30 is completely different. And your pics seems to discount others' suggestions that the EZ30 won't fit between the rear suspension ears.

Good luck on the project!

It might just be a different motormount. Did you try to see if the 4 motor mounts would work on the 6? The 6 mount might be a stronger mount though.

Posted by: TwinTurbo914 Dec 10 2009, 10:23 AM

The engine bar I built for the subie four was hard mounted, and it would not work with my turbo setup Im going to build for the six. I dont have the engine Mounts or engine brackets for the Six they were gone when I got it, but supposedly they use the same mounts for the Four but have a different mounting bracket on the engine block of the six.

But the Engine mount is not going to waste im gonna give it to my buddy that is buying all my subie four stuff to do a subie swap on his teener.

I'm sure you are using solid mounts to avoid motor torque in the chassis but my exerience with aluminum bolted solidly to a steel mount is that it will always need to be retightened I think because of the difference of the heat expansion between the two materials and the vibration and also the lower torque values of the aluminum. I have never tried a aluminum plate in between the block and the steel mount to see if that would help. Not a sandwich plate but a additional plate that the block bolts to then the plate would bolt to the steel mount. It is just easier for me to use poly mounts and not worry about it as getting under a car and retightening stuff is not a thing I like to do. Also aluminum has so much less torque holding characteristics than steel I have thought about bolting through the plate into or through the steel and bolting into the block and through the aluminum plate so the torque of the aluminum is the lower torque and the torque into or through the steel can be much higher. It is extra bolts to come loose so it may still be a extra problem and thats not good. I think maybe thats why harley shops loctite almost everything especially on the solid mount bikes.

I have had to put inserts in some of the fiero trannys to fix threads that get bad from a loose bolt in a mount. Not fun in the car.

Oh hey that shiney header you have on your ej20 looks pretty, but its the same one that i had. It sticks down way too far and the stock heavy one doesnt. I recently converted mine back to stock due to clearance. So it fits nicely under the car now without sticking below the chassis. My power is still just as crazy, even with the smaller exhaust openings in the manifold. Seems to run a little quieter also....that was really my objective in switching back to stock.....

Posted by: TwinTurbo914 Dec 11 2009, 10:36 AM

I actually have a couple of those floating around, I bought another one at sema this year for $40. Im gonna sell them to my buddy who has a subie, and is buying all my subie 4 stuff for his 914. Ground clearance is not gonna be a problem with the headers on the ez30r, plus im making them myself so if they are to low I can only blame my self.

Looks good! Keep going.

Hope to have mine at the track by the end of march.

Ron, that sure is sweet to look at! Will you be starting a thread on your car, with more info and photos?

Scotty, sweet build!

Posted by: quikshft Feb 27 2010, 04:10 AM

First post in this forum guys, this is an interesting thread and build. Seems there should be someone building adapters for the Subaru transaxle so that it can be used with other popular engines.

Posted by: TwinTurbo914 Mar 4 2010, 12:11 PM

Still Working on the car, but progress has been extremely slow. My new shop has been crazy busy. Im working like 12-13 hours a day 6 days a week, so there's not a lot of time to work on the car.

But I did find a few hours to work on it last week and my transmission mounts are almost complete, and the engine mounts are well along the way. Hope I can find some time to finish them up soon, its driving me crazy to see the engine in the engine bay but all rigged up with jack stands and everything else.

Ill post some more pics soon of the engine and transmission mounts.

Posted by: TwinTurbo914 Mar 23 2010, 09:52 AM

Well finally found some time to put into the car, engine and transmission mounts are mostly done, still have to add some gusseting to them, but the engine is hanging in the engine bay. There is tons of room around the engine, and great ground clearance. Now im getting the money together to buy my turbo's and merge collectors so I can start fabing the exhaust.

Here a few pics of it so far

Posted by: quikshft Mar 23 2010, 01:55 PM

I love it when you builders chop the trunk out.

Posted by: Zardozz Mar 23 2010, 03:50 PM

Now I haven't eaten lunch yet so I might be a bit off but I gotta ask. Looking at the center loop, how do you get that out to pull the engine/trans? I think I see some bolts on the second pic by the towers but I'm having a visualization problem.

Bill

Posted by: TwinTurbo914 Mar 23 2010, 04:59 PM

Yah there is 3 bolts on each side that bolt to the shock towers. 8 Bolts and I can drop the Engine straight out the bottom.

Posted by: strawman Mar 23 2010, 05:11 PM

Great work! Are you solid-mounting the engine/trans, or are using any bushings to reduce vibration?

I built a baja about 100yrs ago and when I was done welding I couldn't get the engine out. Glad you were thinking ahead.

Posted by: TwinTurbo914 Mar 23 2010, 07:12 PM

As of right now it is solid mounted but i have the option to add in some rubber pads to isolate it. But it is going to mainly be a race car, so im gonna run it solid mounted for now and see how it goes.

Posted by: Frost Mar 25 2010, 04:30 PM

Man that looks good, that is some nice engine mount fab work.

Posted by: effutuo101 Mar 25 2010, 05:43 PM

very nice!

Posted by: quadracerx Mar 25 2010, 06:25 PM

What kind of tubing did you use....Mild Steel or Chrome Moly? DOM? Just curious....nice fab work....A buddy of mine started to teach me how to weld last weekend....I always admired people who could do it....and now I have a even greater respect for those with that skill..... Im actually ok on thicker wall tubing....but sheetmetal is an art form....LOL

Nice work....keep the pictures coming...

All the tubing is 1 1/2 .095 wall DOM Mild steel, same as the rollcage.

And on a Side note, I just ordered my turbo housings and should have them soon, along with my turbo merge collectors. So things are starting to really get exciting!!

Posted by: budman5201 Mar 26 2010, 11:53 AM

Hey what computer are you using? I just picked up a brand spanking new ez30R with 1k miles!! Will you be able to control the valve lift and cam timing ??

Posted by: budman5201 Mar 26 2010, 12:30 PM

Hey also talk to Outfront motorsports. They eliminate the drive by wire throttle body and use a ford unit which is VERY close to the bolt pattern with a few mods, they said works perfect and that way you dont have to mod your pedal area too for drive by wire,etc.

Posted by: TwinTurbo914 Mar 29 2010, 10:02 AM

Im going with the Link setup, they have all the triggers for it, and are the only ones that I know of that can control the variable valve timing and lift, and all under closed loop.

Posted by: jd74914 Mar 29 2010, 03:24 PM

If you haven't bought anything yet I'd look into the products by Adaptronic. They are slightly less expensive than most other good ECUs on the market and seem to have more features. I know both their e420c and e1280 can control variable valve timing while in closed loop. The e1280 has just about everything but the kitchen sink in it.

I installed, and have been playing with, an e420c on a bike motor and have been extremely happy with the computer, tuning software and overall support. I can't say enough about how impressed I have been with the system.

Posted by: budman5201 Mar 29 2010, 06:28 PM

Does anyone have a already completed map for the EZ30R via the Link.. I emailed quite a few people in Naisoc and another Subie site that have used the v44 and v88 (basically a LINK ecu with different badging.) Hopefully i get a response.

It would be so cool to eliminate that time spent on the initial engine startup,computer setup, etc.

Posted by: DBCooper Mar 29 2010, 09:48 PM

There's an Australian shop, one of the Link people's partners over there, who shared an EZ30R map. It was in one of the forums on the Link site, a year or so ago when they first got it running the variable cams. Check with Link, I'm sure they have a copy or more likely their own version by now.

Posted by: budman5201 Mar 29 2010, 11:21 PM

found a few wiring diagrams regarding the sensors on the ez30 engine and a pdf of the ez30r sensor that the ez30 doesnt have.
So i guess a little easier for wiring now, but no map yet. it does say that the ez30 map is included in the link software, not sure it that will work for the ez30R. I know they are different.

Posted by: DBCooper Mar 30 2010, 09:17 AM

It's Dave at D-Tech, dave@dtechmotorsport.com, page two of http://www.linkecu.com/forum/forums/lem/855742166#690519360 thread.

That's from back in 2007 and Dave did the first map for a customer, but the Link guys were also doing the EZ30R programing themselves back then. They had some problems with the drive by wire throttle body, but I'd assume that's done now. Or just adapt a cable TB. Try contacting them to see where they are.

I'm crazy to know how the EZ30 works for you. That's what I intended to put into my car, but back then there were too many unanswered questions. I even have a 911 sport banana muffler I got so there'd be no clue what was inside until the lid came up.

.

Posted by: TwinTurbo914 Mar 30 2010, 09:29 AM

I talked with Link last year at the sema show, and they said they do have a base map for the ez30r, and they have one of there tuners in socal (cant remember there name right now Ill see if i can find the business card) that has experience with tuning the EZ30r's.

I havent commited to any engine management, as I still quite a ways off from there right now. So im still exploring my options.

Posted by: budman5201 Mar 30 2010, 04:11 PM

wow, thankyou guys for that info. I looked forever, but guess I always missed PAGE 2 of all those posts. That darn lettering at the bottom is small and hard to see.

Cool I just threw Dave an email

Posted by: TwinTurbo914 May 12 2010, 12:07 PM

Not much of an update but, I haven't had much time to work on the car, but I did get a few of my other cars sold, so now I have some cash to spend on the car. The turbo's are on order, and should get them by next week. My merge collectors were ordered the other day and should get them next week also. And now im looking for a radiator to start my cooling system. And on a side note im toying with the the idea of fabricating my own custom aluminum intake, its in the planning stages now, so we will see what happens. Ill post some picks when I get some of the parts in.

Posted by: TwinTurbo914 Jun 3 2010, 03:02 PM

Well Cliff over at Turbo Power in Cameron Park came thru for me. I finally got my Mock up turbo's today. He set me up with some mock up center sections, and compressor housings, and I bought the exhaust housings. So now I can start to get going on the most integral part of my build. I ordered the inlet flanges, and transitions, and some tubing for my up-pipes from SPD exhaust, and I'll probably just pick up every thing on my way thru Sacramento next week. I'll post some more pics of my headers and turbos as I get them into the car.

Posted by: charliew Jun 4 2010, 08:41 AM

So you eliminated the wastegate. How does this compare in cost to just buying a nonwastegate exhaust housing? Like a 30r or is all the aftermarket non wastegate housings too big when you are using two? I must have missed it, it sorta looks like a sequential turbo set, man that will be interesting.

Sorry I went back and found the turbo GTK-350's. I guess the compressor housings are just different because they are mockups and they aren't clocked the same.

Posted by: TwinTurbo914 Jun 4 2010, 09:34 AM

These were not internal gated housings, and these are aftermarket housings, there made my comp turbo, they just installed v-band flanges on the back of them instead of the standard four bolt, as one's with v-band's were not availible. I wanted small turbine housings, so they would spool really fast, they are only .46 A/R, but there is only 1.5 liters going to each turbo, but they will spool really quick, but each turbo is rated at 350-400 horsepower each, so I have a lot of potential. I'm going to run two 38mm external gates, as they control boost a lot easier than internal gates, and I wont have any boost creep. I was playing with turbo placement last night and im gonna work on making a jig to hold the turbo's in the engine bay this weekend, to I can set the placement of them and build to them. I post some pics after the weekend.

Posted by: charliew Jun 4 2010, 09:38 AM

You might want to make the jig a permanent fixture so the weight won't all be on the exhaust anyway.

This is a number I found a long time ago, it may or may not be good. 1hp=1.45cfm I think this came from a old turbo sizing chart I found. I also would guess the turbo place already knows the cfm requirements of your motor at say 7k so thats what size you have picked.

Boy 350-400 from a 1.5 seems a little steep.

Posted by: Zardozz Jun 4 2010, 06:05 PM

That's what I call turbo porn...


I need a moment.

Posted by: Andyrew Jun 4 2010, 06:27 PM

What size turbo's? Vband flange, Nice!

I see BIG power in your future if they are rated at 350-400ea..

Posted by: TwinTurbo914 Jun 7 2010, 09:35 AM

I got the turbo's mocked up in the engine bay this weekend, still have to make the mounting brackets for them to support them. And got one header all fabricated, and tacked together, my dad might go to sacramento today and pick up some more tube and same flanges I need to move forward, ill try and post some more picks tomorrow

Posted by: ClayPerrine Jun 7 2010, 11:35 AM

Now those are some gutless turbos!!!


Cool progress thread!

Posted by: TwinTurbo914 Jun 8 2010, 09:44 AM

As promised here are some pics of the progress, one header is built, just have to final fit it, and weld it up and install a v-band on the outlet for my up pipe, and fit and weld my double slip fittings on the collector tubes. The right side is going to be a mirror image of it, just waiting on some more tube to build it. And the turbo's are hung in the engine bay temporarily, until I make the support brackets to help support there weight, then i'll build my up-pipes to them. Ill post more pics as I make more progress.

Posted by: TwinTurbo914 Jun 14 2010, 09:48 AM

I got a lot of work done on the car this weekend, built my passenger side header, and got both sides all tacked together. And then started on the outlet pipes of the turbo's, got my x-pipe built and just have to fit a few more pieces of tube and the outlets will be done. Just waiting on my flanges, transitions and v-bands for my up-pipes, which I will be getting today. So things are really starting to come together.

Posted by: TwinTurbo914 Jun 21 2010, 06:48 PM

Here's a few pics of all the hot side plumbing tacked together, still have to get the wastegates plumbed though. Hopefully I will get everything final fitted and welded up.

Posted by: Andyrew Jun 22 2010, 12:03 AM

Wowzers!! Awesome progress!!!!!

Posted by: charliew Jun 22 2010, 07:28 AM

Nice fitting on the exhaust. I might be wrong but I'm pretty sure as the tubing heats and cools it is going to move alot. If it's ss it will move more than mild steel. The holes in the rear panel will need to be a lot bigger at the least. I guess if the tubing cracks or a housing cracks you can worry about it then. It really looks smooth though and maybe it will never be a problem. Maybe the holes in the panel will hold the tubing and it will take a set from the heat and sorta stay in the right place. It will be interesting to see the outcome.

Have you got a solution for the heat on the bottom side of the trunk lid? Louvers might be neat.

Posted by: TwinTurbo914 Jun 22 2010, 10:04 AM

The stainless isn't as prone to crack as much as the mild steel, but the holes in the rear panel were mainly to help set a target point to route the tubes thru, i'm going to cut it out and probably make a stainless panel with some sort of support. And on the trunk lid I was planning on louvers to help with the heat build-up also, maybe i will wrap the the tubing also, but thats after I get it all running.

Next im going to final fit everything, and tig the headers and all the turbo piping. Then I might start on my custom intake manifold, but not sure yet.

I also Had the car at our open house car show this weekend at my Shop, We had a great turn out also, about 140 cars turned out. But everyone now officially thinks I'm insane with this project. LOL

Posted by: Zardozz Jun 22 2010, 10:30 AM

That is the sickest set up I've ever seen...

Posted by: wittmer25 Jun 22 2010, 02:16 PM

This is the perfect build! I love this. I wish my dad would follow your footsteps with his 914 project (it will probably rust away until he gets tired of looking at it and wants me to take over the build).

One question, why restrict the exhaust at the merge? You have two 3" pipes that merge together, neck down, and then split again to 3" dual tips.

Seems like you need the merge before the turbos to equalize exhaust pressure on each turbine, then keep it a true dual exhaust without a merge after the turbo. Wouldn't this create less exhaust restriction? Just curious why you chose to do it this way?

Edit: FYI: Mild steel has a much lower coefficient of thermal expansion than austentic stainless steel (300 series stainless) which means it will move more (about 30-40% more). Also, its important to use a low carbon filler material to prevent hydrogen embrittlement around the heat affected zone. This will help prevent cracking around your welds when stressed due to thermal expansion.

Posted by: Cupomeat Jun 22 2010, 02:19 PM

Just my $0.02, but a true dual exhaust is annoying to listen to.

This will be a much sweeter sounding exhaust.

Posted by: TwinTurbo914 Jun 22 2010, 02:31 PM

I love the sound an X-pipe gives ( plus it just look cool), and they are also supposed to help scavenge the exhaust, plus with running two 3" outlets out of the turbo, there not going to be much of a restriction.

I'm glad everyone appreciates the project, it has been a lot of work, but in the end it will definitely be worth it

Posted by: wittmer25 Jun 22 2010, 02:32 PM

I agree about the sound of a single exhaust vs. dual.

That is why I'm using 308 rod which is specifically made for 304 tube, and thats what everyone used for welding up headers.

Posted by: wittmer25 Jun 22 2010, 02:36 PM

I just wanted to bring up the possibility of a restriction in the exhaust if you were going to go balls out with your turbos (max airflow, 600-800hp).

Keep the pictures coming. This is an awesome project! I hope your tranny holds up. Hopefully the tires will spin before axles break

308L is best for 304. The L stands for low carbon. Its what we use to weld up our stainless components at work. We use 304 and 201LN sheet.

Im going to have custom axles made, the vw/porsche hybrid axles I Know wont hold up. And for the transaxle im going with the MRT Unbreakable gear set, they will replace the gear set for free if you can break them. And they come in standard synchro, semi dog ring and full dog ring setup-ups. It might be fun to get a full dog ring setup and run a mastershift paddle shift assembly with the cable shifter assembly, for paddle shifted clutchless fun
