924 / 944 transaxle

[Razor944]

Hey i am thinking about buying an 1980 924 turbo as a parts car for my 944. Just for mainly interior and a little other stuff. I was curious as to if the transaxle in the 924 turbo was better than in the 1984 n/a 944. Does anyone know. Tell me what you think.

From what i've heard the 924 turbo trannies are friggin bulletproof, depending on 4 or 5spd... not that 84 944's have many problems either.

its a 5 speed

the '80 924T trans is exactly the same as the early 944. the only difference is the final drive is 3.89 for the turbo rather than 4.11 in the 944. so you're going to have taller gears. they are both pretty tough.

I think the 80 931 trans mounts a little differently. The one thing I hate about mine is the huge ratio difference between every gear. I have heard they are pretty tough though.

I´m not completely sure about it. But I believe that the 924 turbo 5 speed trans is no the same than the 944 na.
The 924 turbo is weaker than the 944 na.

[nickd]

nope, they're the same audi 5spd. the 924na used a similar unit with slightly weaker internals. the turbo uses the same 944 parts (or the 944 one uses the same turbo parts...). the '80 turbo used a porsche made box that is troublesome.

Did you refer to the housing ?

I have a 924 turbo and I asked to renegade about a v8 kit for this car but tthey told me that I will need to upgrade to a 944 trans or better 944 trans because the 924 turbo have a very weak trans.

[nickd]

ah sorry, i was getting my years mixed up. the 81-82 trans are the same as the 944's except for the final drive. the '80 is the finicky porsche box that often has synchro problems. this must be what renegade is warning you to avoid, unless they don't know one from the other...

anyway, i wouldn't suggest using the '80 turbo gearbox. it's going to be alot more grief than any 944 box. you might want to pass on this parts car if using the gearbox is a prime motivation.

heck.. i just want the interior.. rack and pinion.. seats.. few other choice things and to sell the parts and make some cash.. i was just seeing if the turbo transaxle was worth changing out.. but i guess not.

[Eduardo Castrejón Elbjorn]

mine is 81

I need to research about it.

Maybe, renegade don´t have adapter for the 924 trans (vw engine).

I will research in the pet

[Eduardo Castrejón Elbjorn]

I supose that if are the same trans, then we only need to change the clutch housing and will be the same as the 944 ?

Please somebody let us know if this trans are or not the same ?

[nickd]

yes, the torque tube is also the same. the bellhousings are where the differences begin.

Alright razor...I told you to check the specs..... a 1980 924 turbo puts out 150 hp at 5500 rpms....a 944 n/a early 85 (my car) puts out 150 hp at 5500 rpms...humm..................

[Eduardo Castrejón Elbjorn]

I believe that the 924 turbo puts out 170 at 5500 rpm ?

[jlamont]

The early Euro 924 Turbo has 170bhp (up to '81). Series 2 has 177bhp.

[Eduardo Castrejón Elbjorn]

I supose that the gearbox have casting numbers ?
Can somebody please post the casting numbers of the 924 turbo trans. because if is the same trans in my car than the 944 I will do the lt1 conversion
Please let me know
