run both a 944 rear transmission setup that bolts in, and a quattro setup that bolts in too in one car.

we want to put a quattro tranny in the back of a 944 and run a brush hog off the rear driveshaft :slap: :bump:

I think there were early 924's with n/a VW/Audi motors also... so their front bell housings ought to work...

later 924S were mechanically same (drivetrain) as the 944 with a real Porsche 944 engine, but narrow body shell continued (reincarnated?) from earliest 924's

looks like you have a 924S bell housing there... same as 944

I think the key is it needs to come from a 924 that had the Audi motor... probably MY 1982 or older... as they introduced the 944 in '82 (at least in US)

To confuse thing even more there was an "s" package for the Audi/VW motored early 924's... but all the later ones with Porsche motor were called 924S

Reason I'm so interested is I've been having vivid nightmares about splicing a 944 pan (firewall rearward) into a Corrado shell, and installing an Audi V8

I've been told the 924/944 front suspension and steering will bolt into Corrado Strut towers... Corrado is 75mm - 4" +/- longer Wheelbase so the V8 should sit well back in the Chassis...

I even hired a sketch artist to draw the nightmare...

I missed what chassis you plan on swaping the 924/944 torque tube and rwd trans into...

My idea was to use 944 suspension all 'round (and the "front steer" setup) so the motor would be set way back behind the front spindles... firewall mounted rack woud be first item to hit the dumpster... so picture a 944 pan lengthened by 75mm - my thoughts thus far are that if you splice in the whole pan (at least from firewall back) there is less engineering to do for locating the rear diff, torque tube, shifter...

based on comment above from apavlov13 corrado strut towers would need to be modified... maybe cut out with 924/944 towers spliced in...

Our idea was to carve out the Corrado firewall and push the motor back until it mates with the stock length torque tube... make a new firewall, even move the dash & seats rearward if needed... much better weight balance that way... engine should wind up being almost 100% behind the spindles.. 75mm further back in relation than in a 944

go right ahead and figure that all out for us! :wink:

lots of work no matter how you "ahem" slice it...

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.

I agree totally with this. .................................
By going with a tube chassis, your strong, adjustable, and safe.

I'd need an engineer to help me! :wink:

IF the Audi V8/924turbo bell-housing/UNCUT 944 torque tube/944 trans-axle/944 rear suspension could all some how be swapped in it'd be a big plus IMO... was thinking add just enough of the 944 rear pan and trans tunnel as you could to use "factory" locations for all of the above + shifter...

so the CAD program in my head visualizes as much of the intact 944 drivetrain and rear suspension and FACTORY mounting points for above being carefully aligned and fastened to as much of the original Corrado unit body as possible... and 944 front suspension and steering 75mm further forward to match the Corrado wheelbase

then you could "subtract" stock sheet metal wherever possible as you tied it all together with cage and tube frame... in front use as much 944 suspension and steering as you can... so your finished from front to rear... chassis would-could-should be all lined up to 944 factory specs +75mm of added wheelbase

... but then if you want to be able to change spark plugs with the engine still in the car... :bump:

Thanks Henka -

I was thinking the torsion bars would go for sure...

have a complete QSW rear assembly in stock... (1986 b2 Passat Syncro Wagon)

also will have a 944 ('85) stored in the garage soon for reference... promised my friend it would not have a Corrado body on it when he comes to fetch it in the spring

will do lots of measuring and sketching to try and determine best path... with a degree of difficulty in line with my limited (but improving) design and fab skills...

Just dawned on me that maybe the 944 trailing arms might possible swap into a QSW... possible path to wind up with a 5 x 112 bolt pattern on my other project...
