I own a 05 forester. My engine died and I replaced it with wrx STi engine. Im here in hopes that maybe I can get some guidance as to what should I do next. I know it needs to be tuned. I am a complete noob. Is there an ECU that I can buy to help me tune it? Also I need a new set of wheels and tires. Would a wider tire help. I want to make my car perform like those rally cars. Or as close to it. Its my everyday car but I want it to be just as bad donkey as there rest on this forum. thank you.
