I've always been a fan of the idea for swapping an inline 5 cylinder into a 944. I believe there is a video on YouTube of a 944 with an Audi 20v Turbo motor, and it is a beast. Good luck on this project, I look forward to seeing how it turns out

I'd like to see a BIGGGG GM 3.7 liter H3 I-5 with a 380 hp bolt on turbo kit in one of these ancient 944s.

or rebuilt and tuned for big power....

but the costs to complete the project might be a concern.

Cheers,
These VW motors should be WAY easier to find in the US than the old Audi blocks.

In all my time spent scouring the junkyards, I could count on one hand how many Audi I-5s I've seen.

Indeed. VW made about 100,000 07K's a year from 05-13, so there's 700-800,000 of them out there. This compared to the ~10,000 Audi 20v (N/A and Turbo) I5's they imported from '90-95.

I took a quick peek at ebay to see what the engines were going for and saw a bunch with ~50k miles for under $600...WOW

Yep. Check car-part.com too, lots of cheap ones. Hank Iroz has been collecting all the early 6-bolt forged crank engines he can find. He usually has <30k mile ones with verified forged cranks for ~$800.

would be nice if Integrated Engineering did a "reverse" intake manifold...

...guess SPA turbo manifold won't fit? (shame they don't do a top mount)

Is the engine taller than stock? Maybe you'll have to tilt it like the original engine

Had some free time after work yesterday so I threw the engine on a hoist and set it in the bay. It's just the engine sitting on top of the crossmember/steering rack with the stock oil pan. So yes, it is sitting a little tall and it's sitting straight up. Audi tilted there engines something like 10-12* so I might do that, we'll see. The Iroz Audi mounts do this.

Sitting on top of the rack, plenty of clearance for the steering shaft on the side:

Lots of room for manifolds! The C2 manifold still probably wouldn't work, or at least you wouldn't have much room for a downpipe. I'll probably have the manifold come forward and place the turbo in front of the strut tower. Depends on the how much room I have for the downpipe which will probably be 3-3.5"

The crossmember/steering rack sit quite a bit more forward than the Audi application so the Iroz oil pan might not work, or might need modified. I'm afraid the sump might be right where the steering rack is. The engine might end up coming a little further forward though, I won't be sure until I get the torque tube and bellhousing back in the car.



As you can see, you drop the engine a lot with the modified pan:
Stock:

Iroz Pan:


Depending on the sump clearance, it might be an option to modify the pan and drop the subframe a bit (and line-bore new control arm mounts). Hopefully it doesn't come to that option. A manual steering rack will gain me a little bit of room too.

Some other good new, the chain housing clears the brake booster with no problems. Even more clearance when you til the engine and drop it lower.

And lastly, TONS of room up front! Enought for a nice thick radiator with fan/cowling and FMIC with even more room in the nose for oil cooler/etc.
