Looking to mate a turbo II driveshaft to a RX8 transmission. Are the splines on the tailshaft the same on both transmissions? Positioning on the RX8 trans will be the same distance as the TII trans.

 

Are you sure the rx8 transmission is the same length as the turbo 2 trans?


I wouldnt bet on that, but its possible. As far as the spline goes. I dont know. Get the parts and find out. There are plkenty of driveshaft shops that can make you a driveshaft

 

the rx8 transmission is 3 inches shorter than the tII trans. That's not the problem. I'm moving everything back (motor/trans) 3 inches to line up the shifter in the correct spot. This would also line up the driveshaft to fit.

So I mated the TII driveshoft to the rx8 trans. Looks like it fits snug. I'm just looking for verification. I misplaced my calipers to check. I guess I could count the number of splines.

 

have fun sounds like a hell of a project

 

Isn't the RX-8 6-speed the same as the miata's? My guess would be that the TII will rip it to shreads.

 

It also has the same basic gear ratios except there is an extra gear thrown in the middle somewhere so theres not really much of an advantage.

 

Can I ask why you're doing this swap?
