Hey, my friend and I are looking at buying an 04-05 WRX for him. I own an 02 WRX COBB stage 2 tuned. He has gone for rides and driven my car before, and we both agree we want to get more out of his car. He has owned and driven with 300whp before so this goal is not unreasonable or out of nowhere. Eventually I would like to hit somewhere around that mark with my car as well. Here are our questions-
1)we are having a hard time finding any cars with low mileage! We are strongly considering doing a full build just to start out with low mileage. We are wondering if this is a good/bad idea and why? We are planning on doing a big turbo, fmic, etc. so maybe a build would be smart/necessary to hit 300whp and high boost as it is? You tell us!
2)outside of pistons, rods, bigger injectors, and fuel pump, what would we have to replace in the engine for a full (and safe) engine build? Also what parts (if any) other than up pipe, down pipe, headers, exhaust, turbo, fmic, ewg, boost controller, intake, and engine components would we need to upgrade to reach this goal?
3)how much can we expect this complete build to cost? We plan on installing any parts we are able to ourselves, but include in that cost estimate installation of the parts we can't do ourselves, a protune, and whatever else we are forgetting to mention. Thanks!
