Rick,
You might think about upgrading the transmission to a Boxster/Cayman 6 speed. It's not as hard as it looks.
Right now, with the 901, you have a 215MM clutch disk. With a boxster/cayman 6 speed, you would have a 240MM clutch. I used a Speck Engineering 944 Turbo pressure plate and a Boxster/Cayman spring centered racing clutch disk. You would have to make an adapter plate and a flywheel. If I remember correctly, you used a 901 flywheel bolted to the auto trans pressure plate for the 928. You might do the same thing with the 6-speed.
You need to put in a starter mount, but I already have that, and the trans mount, engineered. You lose the speedo drive, but that is solved with a GPS driven speedo. And you have to completely redesign the muffler setup. The 6 speed is longer and only leaves room for a crossover pipe behind it. Mufflers are too fat.
Axles are not an issue. I have a set that is a bolt in.
Let me know if you want any detailed pictures.
