It has been done already and I contemplated the idea of this few nyears ago. Audi FWD 01E gearboxes are dirt cheap here, you can get one for 150-250 euros. My friend has old Beetle with Audi 4.2 V8 and o1E gearbox (mid-engine), he developed a paddle shift system based on arduino for that too.
Yes, in my research I saw you pop up on a few various threads/forums in regards to this. You say it has been done already. Can you point to a thread Peep? Wondering how to work around "The problem with the 968 trans is the input shaft. No one makes one that mounts to the Porsche splines coupler." As Timm points out, have a custom input shaft made up.
Over the years I have heard of Boxster/Cayman transmissions making their way into 944 cars...
Believe the 6-speeds in those are 01E derivatives, no?
Be WAY easier to make a custom driveshaft coupler than f***ing with making an input shaft.
Take a 944 driveshaft coupler, chop off the 944 trans side, weld on the hub of an 01E-type clutch disk on a lathe to make it centered...bolt it up.
So converting an 01E with readily available SMG parts should be the way forward...spending $20k-50k on a gearbox is "nucking futs"...unless you're so far into the car like Tony is/was that it's sort of a drop in the bucket.

Not sure a welded coupler could hold up to Patrick's immense power and torque?
Looks like the Motorwerks Racing guys use a boxter transmission in their car? It looks pretty similar to google images of the G86/00. But a quick search didn't turn up any dog gear sets for the boxter tranny...so maybe not much help.
stock one seems to be doing OK, and the "clamps" are attached to the splined body by a few little spot welds.
wish i had a better picture handy...
but, even a billet one-off coupler adapter from 944 driveshaft to audi-01E transmission would be a s***load cheaper than making a new input/main shaft...
even if you have to buy the broach tooling for the splines.
Yeah, I'm familiar with the stock coupler. Those spot welds aren't holding the torque though. But I guess welded coupler could be done right and hold a lot of torque...I don't really have any experience with that kind of welding...just brainstorming.
I agree on the billet coupler though. It seems a custom coupler will be needed anyway...because swapping the dog gears into the 968 box doesn't solve the problem as the dog gears come with the audi input shaft. So no matter what box is chosen, you either need a new coupler, or the new input shaft needs to be made to suit the stock coupler.
I wonder if it's feasible to lob the splined end off the 968 input shaft, and weld it to the audi input shaft with a collar?
I wanted to do this a while back and started the project but never finished it.
I did have the coupler designed though by a good friend who is a engineer.
We have done all the test pieces to ensure precise fit and its ready to be produced.
We got a few quotes from some companies capable to produce the coupler but the cheapest was still pretty expensive at around 400 euros.
If any of you knows someone that can produce it at a reasonable price i am more than happy to share the CAD files.
Also i have an idea who might be able to help with the gear selector.
It is the mechanics and pneumatics of the paddle shifter for 01E. Controlled by arduino.
Patrick, the guy who made the conversion is Andres Ringo, he is by the name of Joujaam here. He made the conversion for his 944 bodied track car that has 3.0 engine and 01E 6spd gearbox. AFAIK he made the coupler, that is by far the easiest way.
To me 400Euros is cheap for a bespoke part like that if it was made correctly.
Peep, I don't see Joujaam much these days. Didn't know he had a 944 track car either. Do you have a link to any info on that car/build? I'd be interested in what else would be needed apart from the coupler. I wonder what other parts have to be redesigned to line up the axles and mount the box.
