Hello All

I have decided that come spring of next year the surfacing of a serious garage project will begin.

Project 87AWD

I have a 1987 SPG that is in need of rust repair to the floor pan, and why not at that point go all in!

Mt75
B234
Heavily ported Head
Stock or WŲssner Pistons
Seeing as 6-700 in the powerband can be made on the internals of the stock t5 motors why not put 4 to the ground and maybe more for a full out race car hybrid.

The plan is also to keep the 9000 aero seats for a cozy vintage feel while also having a set of race buckets and a cage to match for track days.

At this point I am gathering a parts inventory estimate through research and questions. The step in the spring is embark on that inventory by purchase and fully immerse in the custom fabrication needed.

Thanks for the time and I hope you will follow as it happens

What is the plan for the drivetrain? I know you said you're going to use a 234, but what will you use as a transmission? Rear differential and axles?

At the moment I am looking into a Cosworth Mt75 or a omega6. Rear Diff I am unsure at the moment. Axels will probably be a custom job utilizing the inner drivers and out boot and splines to fit a Saab suspension setup

Thank you! Should be interesting, frustrating and costly but most of all a total learning experience.

Beginning Phase Has Begun! Carpet, Sound Deadding and Pedal Out. Lots of rust to tackle and floor pan welding. I have settled on a Borg Warner as mentioned. T5 To a unmarried S10 AWD transfer case. Digging a tunnel should be a little more practical now. Lots of rust!!! Lots more to come this weekend!

I envy you. I wanted to do this to an SPG for a while, but the dream faded.

Just the beginning g stages, finding so much rust and needing to repair things is fuel the fire to get it done!
I really hope that I can share this project for those like myself who want or wanted to make this possible.

B202 is out!
Decided to go with a 1995 Audi 90 b4 Quattro Transmission as the AWD tool.

Pulled the trans from a local parts yard. Drive shaft and rear differential also pulled.

Yes, very cool. I'm particularly interested in the engine mating and clutch arrangement. Is that drivetrain up to handling the 6 or 700HP you're targeting?

Iím hoping with a few other findings and weight determinations it will be possible or at least a compromising powerband. There is a shifter made by CAE that may reduce strain on the trans by changing things to cables. Iím still researching.
So far I am in touch with a guy who is designing a adapter plate.
This will allow use of the b234 flywheel, Audi clutch disc and b234 Pressure plate.

After this I contacted another local shop who are going to fabricate axel shafts to accommodate possibly keeping use of the stock suspension upfront or at least the hubs so that I can run the 9000 Aeros Iíve got on the car which I also plan to have widend yo fit a 225 Tire. Thatís of course down the line.
First things first!

-Mate the trans to motor
-mount motor and trans in car
-figure out wiring
...
-begin the rear axel(s) Layout

-GET IT RUNNING

-paint interior
-Focus on exterior

I have been sleeping on this project as I build a motor for my Viggen but gather parts to outright complete the puzzle.

I spoke with a guy named Larry who runs a small Audi shop and dealership here in Colorado. I asked him about the power afforded to the b4 trans being a pikes peak winner in a Audi and selling nothing but Audiís on his lot. He was very open to talking about his builds and how industrious the b4 is. He said that they ran the b4 in a twin turbo Audi making 700 on the same trans for 3 race seasons! That is remarkable in my book.

So, thus far I have a 1995 Audi 90 Trans, Drive Shaft, differential and more recently I was fortunate to come across another 95 Audi 90 and pulled the entire rear Subframe assembly out!

If you can imagine my intentions here for the rear end conversion... itís pretty cut and dry, make everything level and bolt up the rear end from the 90 to the SPG.

I am also waiting on a adapter plate for the b234-b4 trans. That conversion has yet to be complete but will soon be on the list of completed items. Then mount making and floor pan design implementation.

I can't wait to see it completed. Gathering parts is still progress in my book.

The heart has been pulled (1996 2.3t 9000). Off to adapter plate mocking and the machine shop. Nearly all the puzzle pieces have been found... now to make it all work
