    What would it take to beat an EP3 Hatch

    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?

    At XPT stage2 you are strong enough to take him HARD from a dig still. Everything I hear about the XPT states it is nearly as strong as a protuned cobb stage2 map.

    From a roll though, you will probably need a bigger turbo. The EP3 Si with just bolt on's is good for trap times in the 96/97 range so with that blower he is probably in STI trapspeed area.

    If you run him in your current condition go from a dig or very low roll and you should take him. If you want to take him from a higher roll, get a larger turbo.

    To be honest with you I had an 03 EP3 si with header, intake and catback and don't get me wrong it was fun to drive but after having a stage 2 wrx I really doubt even with the SC he will destroy you. I think it might be a good race. From a dig you will kill him. From a roll it will be close maybe (you still coming out on top). Now if it was a rsx-s SC it might be a different story because he would be starting with 200-210hp not 163hp.
