i was wondering how much horsepower i'd be pushing in my N/A if i got a mild street port, ported my intake, ported my upper and lower manifold, ported my exhaust got a racing beat exhaust system and upgraded injectors? any ideas would be great i think this is the way i am going to go! thanks. oh and what about race rotors??

 

You wouldn't need the larger injectors for the NA. You have a S4 motor, so i'm guessing around 160 to the wheels.

 

the n/a rx-7 comes stock with 146 right? well the car right now is lower than that unless you maintained everything really really good, so with a street port and all those other ports, i would think more around 180...

 

is it 146 to flywheel stock? or wheels? (I'm thinking FW)
