I used a gear set from a '96 Miata and I noticed the following differences versus my stock '89 transmission:
-Second gear has two synchronizers
-The reverse gear has a helical cut
-Small casting differences in the bearing plate
-No gigantic weight on the output shaft
I used the front (bell), gear (middle), and rear (tail) housings from the RX-7 transmission. The bearing plate and everything else were from the Miata transmission.

I guess i just got the idea in my head to do the miata gears swap and wondered how much power i could throw at it (maybe around 350whp max?).

So, like most RX-7 issues, its usually the driver at fault.

That makes me not worry so much. I guess I could always do the TII trans. But as i said above ^^

So you think if i had the gears cryo treated id be ok even if i ran around 350whp? I mean I'm not gonna be tracking the car. Just spirited driving really.
