Boxster parts

[djjohnj]

I am not as concerned with the sanctioning bodies rules at the moment. I am just trying to understand the interchangability of parts.

So will the 6 speed bolt up to a 2.5 without too much work? If so what else needs to be changed? Are gears readily available for the 5 speed?

To the best of my knowledge, the only interchangable parts between the 996 and 986 are the front bumper, and interior (dash, seats, radio, etc.).
The electronics, engine, some suspension, and everything mechanical is different between the two.

Good question. I'm not sure if it bolts straight up or if some form of adapter plate and different mounts would be needed. My hunch is it should be quite possible to put the 6-speed from the S into a base boxster, however it will be much easier to source an LSD for the base boxster tranny. There is an active group of racers that are developing a Spec Boxster series -- I think you should call the shop that is leading the effort as they will have the best intel on racing parts for base boxsters.

the six speed from an S will bolt right up, BUT the half-shafts will not attatch to it. the inner CV joints on the 'S' model are larger. one would either have to replace the inner CV joints OR replace the output flanges at the tranny.
