I just got a 2002 Wrx Impreza.. I got it completely Stock it has 120,000 mile on it. I just bought a cold air intake, from STP, I did the timing belt, and bought a 3 inch exhaust down pipe back. And I have me some sick snow tires from michellin. I want more HP and performace. I looking for a turbo upgrade. But I don't want to go to big where I'm running into engine problems.. I need help on which turbos are good upgrades since this is my first subaru. I plan on getting MSG ignition and possible a ecu or computer for turbo depending on what y'all say. Take into effect that this is my daily driver and I live in Mass and I need to Pass inspection. Thanks everyone for you help.. Cause I sure need it!
