I was thinking about getting an RX-8, and I was wondering how much power potential they have. I know they're about 240 at the crank from the factory, but how much can its power be raised while sticking to natural aspiration and bolt-ons. Also, how do you tune an n/a car anyway? For instance, if I took my rx-8 and got a full catless exhaust, would I take it to a shop and get its air-fuel ratio tuned with a piggyback like you would a turbo, or do you go about it differently? Sorry for being so clueless, I dont have much knowledge on rotarys or building fast n/a cars.
