My buddy just bought a 2004 Honda Civic Si (aka EP3) it has the K20a3 motor (the crappy 160hp VTEC Honda offered in the 02-05 Civic Si). But heres the kicker, hes already bought a used Jackson Racing Supercharger, an intake, race headers, and a catback.
Now normally I hate magazine racing but I know for a fact that he will destroy me. So my question is whats the best way to make enough power on my 02 WRX to atleast keep up with him? I am currently XPT Stage 2 with a 3" TBE, gutted UP, K&N Intake Filter. Is there any way I could make enough power with just a dyno tune?
