Could You.....

Dr.Boost's thread What ever you do, don't.... got me thinking.....

could the rear transaxle in a 924/944 be locked in either 4th, or 5th gear, and then a driveshaft added to a more conventional engine/trans combination?

Im sure you could, but can't think of a reason why you would.

I would either adapt the motor of choice to the stock torque tube and transaxle, which is done quite often as the face of the torque tube has a 4-bolt flange that is easily adapted to bellhousings of your choice.

Or

Pull the box and torque tube completely and replace it with a transmission, driveshaft and rear diff bolted to the axles (the CV joints use the same bolt pattern as most VW's, and Porsches, so adaptation wouldn't be too difficult)

You could also make it so you could only swap between Fourth and Fifth (Direct drive and overdrive)and then use a regular transmission and use it like an auxiliary overdrive unit or a two-speed rearend in a big truck.

This was kind of my thought.... call it short track, or long track gearing

If the chassis is decent, a BEAMS and a 6 speed can be had for about $1300 - add mounts, and you'd be in a 200hp 160#/ft in a 2600(+ or -)lbs Poryota 924

A few fine examples... near me....

much less than a grand

The trans is an Audi 016 with a different kind of input shaft. I'm not sure that you would want to do heavy torque multiplication upstream of the trans.

However, if you put the "splitter" transmission upstream of the 016 instead of using the 016 for that, it might live, or at least not die so easily.

Or you could leave it as is and put a motorcycle engine and transmission in front of it. Fourth or fifth for the highway, reverse when you need it, and for the short autocross courses toss it in second or third and shift with the bike trans.
