ok iv been looking around on here yeah im new sorry
but im trying to do a vr6 swap on either a 924/931
or a 944, preferably a 944 but either way,

i see that the 931 bellhousing is the same as a audi
umm 016 i gues, and 034 motorsports makes that adapter,

ok now will the 931 bellhousing bolt up to a 944 torque tube,
or can i make one by welding them together or something

i dont car about making mounts i can do some welding, not worried about that

i have a 500+ hp VRT im accumulating parts for
i plan to make around 700 whp.
mayble like 400 just playing around

but i need some info on the bellhousing #'s

dont know that much about the 924's

im a vw tech and i have a 944S2,
im a BIG VR6 fan i already built a 400 whp jetta lol and it was fun as hell
but i want a rwd VRT

thanks for any help guys

The 924/944/968 torque tubes all have the same bolt pattern and inside bore size.

[dabeetereater]

ok cool

so the 931 bellhousing is the same as a audi

but what code is it,
so i can call 034 motorsports and find out if their adapter will work and what flywheel i might be able to use,

[fiat22turbo]

what code are you looking for?

http://en.wikipedia.org/wiki/Porsche_924

"The original design used an Audi-sourced four-speed manual transmission for the 924 mated to VW's EA831 2.0 L I4 engine, previously used in the Audi 100 and Volkswagen LT van and producing 95 hp (71 kW) in North American trim"

i want to know the code off the 931 bellhousing

if i read right its 016

and if its the same 016 bellhousing as a audi then i can use the 034 motorsports adapters and bolt up a vr6 right into a 944, minus some mounts and all the other good sutff

but i also need to know weither the 931 clutch is a push or pull ?

that is gonna be the determining part

im trying to talk to the guy who did the 20v 7A N/A motor in the 944 to find out what he did

[alexvex]

Why not use the 931 bellhousing/clutch/slave/etc and have the 931 flywheel machined to bolt to the vr6? I think that is the way i'm going to go with a audi v8 in a 931. Shouldn't cost more than ~$150 at a machine shop.

Yes, it is an 016 and it is a hydraulic pull type from an early 911SC. The standard 924 is a cable-driven push type taken from the Audi 100LS.

Personally given the rarity of a 931, I'd find a 924 bell housing and adapt an external slave cylinder to it.

Either way you'll have to have a clutch/flywheel customized to work with the VR6.

is a regular 924 bellhousing the same as a 931, besides the hydraulic clutch part

cause all i have to do, i already found a flywheel to work and a clutch but its a push clutch,

so if a 924 bellhousing is a 016 also it will work just fine i dont mind a cable clutch i would acutally prefer it,


but if they are both the exact same otherwise i will get one of those
i found one on ebay for cheap but i was not sure if they are thesame

[fiat22turbo]

Okay, now slow down and go read the FAQ or even the Wikipedia article on the 924 and 924 turbo.

Major differences:

Cable clutch versus hydraulic (944 hydraulics)

Starter mounts in opposite directions (turbo mounts from the firewall side, non-turbo mounts from the engine side)

flywheels are different (turbo is slightly larger, includes a location for the ignition pickup on the series-2 924 turbo as well as mounting for the 911/944 clutch setup)

Clutch/pressure plate are different (944/911 pieces)

Torque tubes are different (turbo has a larger 944 tube and spline)

Either way, they mount to the engine the same way and they mount to the torque tube the same way which is really all that matters to you.

The key is mating the torque tube to the transaxle being used in the car. The 924 non-turbo torque tube is strong enough to around 250hp, maybe a little more depending on how hard you drive it. The 944/924 turbo has a larger diameter shaft and will support much higher power outputs and abuse.

However, depending on which transaxle used there are different lengths. The Porsche 915 transaxle aka "snailshell" (dogleg shift pattern for 1st gear) has a shorter tube than the later Audi 016 transaxle used in the 931 and 944, etc.

So if you convert your 944 S2 then you should be good to go aside from converting to a cable clutch. If you find an older and lighter 924 or even an early 944 to convert then you may have to swap some parts around depending on the year involved.

ok i see,

im trying to put it in a 87 944T car

so i might try have have to make the 931 housing work,

although the adapter plate i need and the starter and flywheel

the starter bolts from the motor side.
so that might be a problem with the 931 housing


hmm i might just need topick up both and see what i can make of either of them

[alexvex]

what's wrong with the 951 engine? I'd just stick with that.

[dabeetereater]

cause i have a 3.0 vr6 with a T67 turbo big valve head
that will make over 600 easy with the right tuning

[dabeetereater]

this was on 15 lbs not running very good

and without the bvh

[FSMITH010]

any updates?

[beario]

did you make an adapter for this in the end or give up...
