Anyone ever adapt a Corvette transaxle to a 944/928?

Quaifes are cheap compared to the cost of fabrication.
928 automatics also have a separate tranny and diff, but the manuals are true transaxles.

Z06 units are one piece but the trans is in front of the diff where our cars have the diff in front of the trans. You would need to reshape the metal under the back seat to fit around the trans. Then fab up trans mounts, etc.

So a "transaxle" is the gearbox, differential, and drive axle as a single unit. Which is the weak link on the 944? Is it sufficient to fit a high-quality LSD, or are other parts prone to failure under the strain of a more powerful engine?

I'd be worried about the trans not being able to take the power, but not before the axles. But, what kind of power would you need to make, to necessitate a corvette or built trans?

I dont get it. Unless youre downright abusing the hell out of your transmission, then there should be no need for something like this.
A 951 LSD is for the most part pretty damn indestrucable for the power that 95% of 951s even put out.
Why try and reinvent the wheel, when theres nothing wrong with it at all?

corvettes up until recently put out 500hp max...(you will not find a ZR1 tranny for some time)...considering that one of our users here has gotten over 600HP at the wheels on his 951 and is still using the stock turbo gearbox, i would say its pretty tough.

I suppose those 1000hp twin turbo Vettes, or the 1200hp camaro running T56's local to me are mythical as well.....
Yes, it's doable, Steve Rea has done it to his car which runs enduro's (NASA events I believe?) west coast:

You can see the tube work if you look closely used to mount the C5 rear crossmember and suspension.

Guess my blown gearbox was a fluke? Or Tifo's on his NA? Or Dmoffitt's on his turbo? Or the variety of other ones?

Yes, some people break the 944NA transaxle but you can install 944S2 transaxles as stronger replacements. Adding an LSD is not cheap but a different transaxle would be a huge, expensive project that would cost 10x more. Besides the cost of the new transaxle and perhaps LSD, and the basic fabrication you have to deal with:
custom torque tube
custom axles
fuel cell
speedo drive
