I'm sure someone did this before, I want to do it to mine, but for the front, Mazdatrix's web site said :

"Does fit all 13B, hardened multi-window bearing, set screw retention. Bearing clearance must be checked/modified if using this with any RX-7 13B shaft."

Anybody know why is that? The reason I ask is I thought the stationary bearing is the same size for all 13b ?

and for the rear I searched and found some topic saying that the rear's oil galley(the hole?) does not line up correctly and need to dremel it to fit?



Thx

 

So, I have RX8 gears and they installed without any problems. My oil gallery did have to be modified to line up correctly, but I know a guy's who didn't have to be modified. Not confirmed but we think this was because his was a 6 port hi power bearing and mine might have been a 4 port low power front gear.

 

oh I see

Im going to get it and compare(measure) it just to be sure. if anything I just grab my dremel tool and grind that sucker out.

thx
