I have a 2002 WRX wagon that I purchased a couple months back with 190k miles. I love the car but the engine has some miles on it and I'm wondering which direction I should head in. Will I be wasting money by purchasing a larger turbo with the accessories needed to run it? I really don't have the money to buy a new block but I don't want to throw my money out the window if I buy a turbo and my engine craps out on me either. Could someone please give me some suggestions on what I can do to get a little more HP (50-75) out of my car but still maintaining driveability as it's my daily driver.
