Another project thread..., with an Audi 2.7T motor/trans....etc... Options

[914_1.8t]

Another project thread...

So I pickup up a stripped tub with Sheridan standard body kit. The car is completely stripped down with nothing but what appears to be a stock front/rear suspension and brakes...nothing else other than a roll cage and some holes in the floor and trunks. Initial plans were to go all out with this project but plan has changed. I ended up picking up another project car (that I've wanted for a long time) and tried to sell this but couldn't.....so I've decided to just build it with whatever parts I have lying around and keep the out of pocket expenses down as much as possible. I'm hoping to keep the budget as little as possible...hopefully under 7k (other than what I already have). Car will be minimalist and have as little weight on it as possible and little to no extras (no carpet, side windows...etc...) initially and just get it running and add items if need be later.

This will be a s-l-o-w project and I will work on it when I extra time aside from my other projects and life in general. I still have to figure out what I want to do with this.

Parts I have in my garage:
-914 Tub w/ Sheridan Kit
-Audi 2.7T Engine (bent valves)
-Replacement Heads/Head Gaskets/Head bolts/Timing Belt
-Stock 2.7T Intake manifold and VR6 TB, TB Cable and Pedal
-Audi 01E 6spd with welded diff, and stock slave cyl
-Cluthmaster Stage 4 clutch with 12lb Aluminum flywheel (clutch disc needs replacing soon)
-GT3071R turbo and GT4088R Turbo
-Tial 38mm WG
-Tial 50mm BOV
-044 Fuel pump
-Summit Fuel cell 16gal
-PWR 2921 4"x8" Barrel air/water Ic (rated to 300hp?) or Garrett 400hp air/air IC
-1.5" Aluminum tube for radiator lines
-18x8.5 Front/18x9.5 Rear wheels with 225/40 and 285/30 tires (5x112 bolt pattern)
-Ebay Racing Seats
-Rx7 Shocks/Spring combo
-(2) 4'x8' Sheets of Sheetmetal


Things I need:
-Radiator and fans/shroud ($200 Ebay)
-Muffler(s), Intake/Exhaust/Exhaust manifold tubing (ss304) and flanges, DOM tubing, etc... (~$1000)
-Porsche 996 Cable Shifter (???...150-200)
-Custom Axles (???...200-300)
-Standalone (SEM) (1200 used)
-Wilwood pedal set ($250 Ebay)
-Gas/Brake hard lines (100)
-Suspension system/brakes (~$2000)
-Vinyl body wrap ($500)
-Hood (???)
-Trunk Lid (???)
-Turn signals and rear lights (???)
-Rear Bumper(???)
-Door handle and mechanism (???)
-Windshield/Rear Window(???)

I still need to decide on the suspension/brakes (front/rear). I would ideally like to get spindles/control arms/brakes from a donor car. Initially I was thinking a 996 (front and rear) but still undecided. I'm trying to figure out what other option are out there? I'd like to get them from a similar sized car (or compact sports car) that already has a good set of brakes from the factory. I'm also determined to use the wheels that I already have (5x112) b/c I'm attached to them (IMG:style_emoticons/default/confused24.gif) ....either I will have to get adapters or get a suspension/spindles from a car that is already 5x112. I'm open to any suggestions/ideas?

I don't really like the roll cage and it will be coming out along with the trunk to make room for the engine/transmission.

So anyone have ideas on what car to get spindles/brakes/control arms from? The cheaper the better. Any MB vehicles?

I'll be rebuilding the engine this weekend...I'm hoping it is just some bent valves and can simply pull the old heads and replace with the new (low mileage) spare heads I have. Hopefully no piston damage from valve contact. This motor stock should be able to handle 450-475whp and that should bee more than enough for what I want. (The 3071r should be good for ~340-375whp with good low end torque I think. Lets hope this goes smooth and I dont have to worry about the engine after this weekend.

For the fronts, you're probably gonna have to go billet hubs if you want to keep the uprights. For the rears, there's theoretical solutions in the parts bin. mk5 and later vw, audi, mercedes, bentley all ran with your desired bolt pattern. The VWs Audis and Bentlys share the same wheel bearing as the 914. It's a nut I've been meaning to crack, just haven't gotten arround to.

[rohar]

Oh, and it looks like the v6 motor mount isn't gonna work on my new v8. If you wanna buy yourself out of a couple of hours worth of fab, it's available.

Well I'm not really worried about cutting away the stock body/frame and fabricating whatever needs to make something work. Actually thats the whole appeal for me with this project, kind of starting with a blank slate and having freedom to whatever comes to mind. With my other cars I have (I've had in the past) your always so limited to what you can do.

The trick to finding a donor car is trying to find something with good brakes from the factory and suspension geometry that will work on a 914. I can always get adapters made for the wheels. Also want to go with a dual a-arm type of setup if possible. And power brakes/steering would be nice as well.

Couple more pics of the stance I will be shooting for....probably another inch lower in the front and 3 inches lower in the back than this:

Nice wheels, this is going to be fun!

Well if a ton of fab is an option, might I suggest:

(IMG:http://www.914world.com/bbs2/uploads_offsite/fastforwardracingcomponents.com-9685-1320444146.1.jpg)

(IMG:http://www.914world.com/bbs2/uploads_offsite/fastforwardracingcomponents.com-9685-1320444147.2.jpg)

$300 each and accept the Audi/Porsche/VW bearing.

Can you give some more info on those please? Link?

Sorry, I'm a bit of a tease. They're designed for DSR sports racers, but due to availability many of them use late model VW/Audi stubs so they're in the ballpark for a build like this. Same manufacturer has fronts but you gotta use stubs in them as well.

Those in the image are from FastForward: http://fastforwardracingcomponents.com/ I love the axial mounts for the calipers, all kinds of options open up.

You can find all kinds of messed up custom stuff here: http://locator.pbworks.com/w/page/18642654/Suspension

[mark21742]

You could also look into pontiac feiro rear suspension(mcpherson strut), or I think I might use pontiac grand prix front hubs in the rear of my project...if you don't mind doing some fab work to make suspension mounting points, just stick with older 80's-90's GM parts to make a cheap, strong AND light rear setup. If you lived closer i'd give you my extra engine cover.....you may find some people close by to donate some needed parts....as for a windsheild, do want to keep it near stock appearance? If not, you could go with a donor windsheild and frame....I picked up a good 98ford escort glass for $65 and built a frame, Ford escort, hyundia accent, and a few others have the right lower width for the .914, but are taller so you can rake the glass back giving a more modern look to the car

Thanks...I'll look into it and see if its a good option.

I'm going to try to keep it stock appearance on the windshield and such...will be looking into possibly fabricating a metal roof down the road as well.

I'll look into the gm stuff as well for the suspension. Figure any type should be ok as long as I can get a custom axle for Audi CV to the new spindle.

If 5x112 bolt pattern is a requirement, without adapters (bad things happen here) it limits options. Besides, if you can come up with a solution that uses Audi stubs, axles get real easy. I'm doing it with an Audi tranny and 914 stubs right now, you don't wanna know the machining involved.

[mark21742]

Never tried it, but I really don't see annual difference in resplining an axle, or resplining a CV joint......I hope it's that easy, because I'm planning on needing ot done too lol

Why not use the factory audi strut assembly? Good opportunity to go with a multilink setup if you were up for designing it.. As you probably know the audi suspension is a pretty good design.

BTW I love this build.. You got enough turbo? I mean seriously, thats a 600whp setup with your bigger turbo... On the low end... The GT28 guys are running that much HP and the size of those turbo's... Gosh... That seems like a bit much (IMG:style_emoticons/default/smile.gif)

[mark21742]

Rohar, that's my problem, right now I'm looking at going Honda drivetrain to Porsche hubs....for the moment, but might go GM hubs (have a set of early 90's grand prix) hubs laying in the garage

This is what the audi front/rear looks like (Audi Uprights):

It will extend too far up above the tire...I will run out of room...mocked this up on my last build and they are not useable. That is why I want something with a dual a-arm type setup.

GT40R is really big for this setup, can't rev the stock motor much past 7K RPMs and really utilize that turbo...ideally a GT3582HTA or GT3586HTA would be perfect. Stock 2.7t can handle ~475-500whp (w/ 25-28% drivetrain loss that comes out to 600chp). So with RWD only and about 15% Dtl I'd say the motor could safely handle 500-520rwhp and rev to about 7200K RPM. I have a built motor in my S4 project with gt2868hta turbos and Its not really worth it $$ wise to build a 2.7T, there are better alternatives out there for the 914...so the motor will stay stock with a ceiling of 475-500whp. Besides, the 3071r should easily make 340whp and that should be plenty in the start in this car...I made close to that with this same turbo in my 1.8t. Eventually I can see myself with going GT35R sized turbo later on if all this works out ok. Don't want to get ahead of myself.
