Yeah, I'm working through that issue now. Its so hard to find a trans with the short 5th and LSD that it might be worth it to throw a spare in for now and then fix this one later. Its definately hard to find these things around Texas so I think the prices Im seeing are a little inflated. I have a line on two right now, one in Houston (out of an 84) and the other in Alvarado (out of an 87). The one in Houston is cheaper but a little older and neither have a short 5th or LSD.

Anyone know if the 5th gear out of a turbo trans will fit in a NA trans? The 87-88 5th gear is the same ratio as the desirable short 5th and they have a bunch of those parts down in Houston. Do we even use 5th gear at Eagles Canyon?

Hey Jason,
the fifth gear from a turbo trans is a direct swap to an NA box. It's not hard to do but i have had trouble getting the gear off the main shaft some times. Usually it will slip right off. There's a good write up on how to do it on the 944 spec forum in the tech articles section. And i'd bet we willl be in fifth at the end of the straight between turns six and seven and maybe between five and six.

Well, right now I am on hold. I had ordered some parts last Friday that would let me finish putting in my usednew gearbox but the order was saved as a quote so it never shipped. Basically Im a gasket kit away from being able to install it so I can load up and goto the track. I likely wont be able to do the track day so right now Im planning on being at the track sometime late Friday afternoon. Im still uncertain on this gearbox since I havent actually moved the car under its own power with it so can somebody bring a spare gearbox just in case? Its been offored by several people, just want to make sure somebody will have one. Hopefully I wont need it.
