I realize this is something that has probably been beaten to death 9 different ways on this forum but I’m having trouble figuring out what transaxle numbers I could use to find a relatively easy swap candidate for my 1977 4spd 924. It’s going to be used for street/daily driving.

What I know so far:

1. My car is non-turbo with rear drums, my understanding is that I currently have the transmission and torque tube with the 20mm input shaft so so the torque tube would have to be changed along with the transmission. Stock motor is staying in the car for now.

2. I’ll have to figure out a new shifter linkage and hydraulic clutch etc.

3. Suspension will have to be updated to 944 stuff/disk brakes all around.

4. Current numbers that were on the table for transaxles that are possible are:

Audi numbers 016, 01x, 01E (depending on year as apparently they change to AWD gearing at some point.) it’s been mentioned in my research that 1st is relatively short in some of these but again this is a street only car.

I’d like to buy the transaxle and suspension parts a la carte as I don’t really have the space for an entire donor 944 (which would probably be more ideal, I know).

Getting sidetracked from the original goal of this post though, are there any other transaxle numbers that I’m missing, any pros or cons of the ones I’ve listed? Any other work involved that I may have over looked?

The goal is to get a decent transmission swapped in and drivable before I start working towards an engine swap (I’m eyeing the 1.8t since it’s a somewhat commonplace swap).

I appreciate the help in advance and again I’m sorry if this is beating a dead horse.

Unless you really just want to build a car you would be better off with the much more refined 924S or 944 and then change the motor. There is an outfit in Georgia that makes 1.8t conversion parts that make it much easier.

What your looking to do could get pretty complicated. I'd find a 944 for the rear suspension and brakes. The front can also be used, but requires fabricating brackets for the 944 anti-roll bar. The only transmission that would do you any good and fits is the 016/9 5 speed with its 4.11 ratio from 1981 and up as it has the 20mm shaft. The 78 4 speed has a 3.88 rear axle ratio rather than 3.60 in the '77 and the 79 and 80 have a Porsche transmission requiring a different torque tube and torsion bar carrier to hold it. The 931 has a 25mm shaft and and transmission also requires changing the TB carrier. Audi trans have a simple linkage, the Porsche ones much more complex and parts more difficult to find and can get expensive.

Good Luck

So basically you want to change everything except the body?

Probably cheaper to buy another car..

Why a 1.8T?

I don’t really get the whole 1.8T thing..
Their head is cool, just had one in my hands the other day.. Their manifold/turbo is rediculous.. Was just playing with one..

Yeah their easy to get a little more power out of, but it’s not that much, and I wouldn’t think it would be worth swapping for..

IDK.. It doesn’t tickle my fancy..

A wet shot of NOS should work just like on a carbureted engine I would think..

See if you can find any local speed/performance shop to do it, or atleast make sure it is tuned correctly..

Bet you could have it all done even with some pro help for under $1,000..
And in like 1 day..

So I actually ended up finding and buying a clapped out 944 as fastEddie and mikejinco suggested, $500 and it’s a blank canvas, I’ve decided I’m going to leave the 924 alone other than maintenance and safety changes since it’s already a good car.

Think I decided I’d feel better about starting with a blank canvas than changing something that already works like both of you already pointed out. I’ll probably still do the supercharger upgrade when that comes out though too
