So if I read all of this correctly, A porsche 924 bell housing WILL bolt up to an Audi 3.6 V8.

Does it need to be a 924 turbo, AKA 931, or can it be a plain old 924.
I can deal with the clutch release as long as it bolts up.

Well as someone that is putting an Audi V8 and a 944 drivetrain in a VW (if you can still consider my car a VW) maybe I can shed some light on the situation.

The 944 and the VW I am using (Rabbit) have nearly the same wheel base at around 95 inches.

I have moved the engine back in my chassis so that there is only about 6 inches of any engine part ahead of the front wheel centerline.
I will get back to all that in a minute.

First here is how the engine sat in my chassis before I did any cutting.

.
I was not pleased with how much engine there was in front of the front wheel centerline so I cut the firewall and moved it way back.

However that was too far back for what I was doing at the time so I moved it forward a little.

I eventually decided that I was going to build a chassis and mount everything where I wanted it and I believe this is the only way to do it without any compromises.
You can see in this pic about where my engine sits in relation to the front wheel.

Now back to that whole wheelbase thing.
Maybe it is because I moved my engine back so far in my chassis but I will need to remove 12 to 18 inches from my torque tube to make it work with the 95 inch wheelbase..

I am not real sure that you would ever have to lengthen the torque tube.

Next I would like to cover the topic of bell housings.

I have not actually bolted my 931 (924 turbo) bell housing to the V8 yet but I have set it up in place and it appears that there will be 4 or 5 bolts that will line up.
But most of them are on the starter side.

I would like to know if the S4 spacer is necessary but I am going to try it without for now if I can get it to bolt up adequately.

I will know more after this weekend.

I have not even begun to figure out what I need to do for a clutch but I am sure that will open a whole new can of worms.

You could do what I was going to do in the beginning.

I planned on removing only the necessary original body material then welding in some subframes of sorts made of mild steel tubing and plate that all the other car parts would bolt to, sort of like what this gut did

There are a lot of good suspensions out there that use subframes that you could modify to fit the 944 trans then bolt into your newly fabbed frame structure.

The bottom line is this is there is no easy way to do this.
it will involve a substantial amount of fab work and a little ingenuity.

In case you haven't seen it, this is what I ended up doing.

This is all the further I am with the chassis.
