The box has had steel synchs and the Albins short 3-6 gears installed. I added a G50 diff with GT parts and changed out the stub axels. Also added a transmission cooler provisions to use my existing system. To use the 6-speed box in an early Boxster, I had to get some new trans mounts, some Boxster S rear uprights, and some Boxster S axles.

In between the two will be a new AASCO flywheel and Tilton 7.25" twin disc metallic clutch unit.
