how much power can the NA tranny take?
I don't know mazda's ways, however most of the time, the only differences are gear ratios and what not like that....
why is the driveshaft different? I've never seen a turbo2 engine in person, so that might have been a pretty self apparent question once you see one, lol
what are the rear end ratios?
Suggestions on the best combination for acceleration? top speed? overall drive ability?

I'm just starting the processes of learning, so I apologize for the dumb questions.
