I'd say about as much as the N/A RX-7 transmission. That is, not too much. I've seen both transmissions completely disassembled and I didn't see anything that would indicate the Miata gear set is any stronger or weaker. That's not to say there aren't any differences. 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.
