Hi guys I have a question about the things I can do to my car . Ok , so I have a 2002 Subaru Impreza base model non turbo , with a 2.5 ltr engine . I was thinking if I were to add a turbo and an exhuast system to the car will it be able to sound like a wrx or an sti , or do I have to do something else , Also can I mod the car to the point were my horsepower will be around 600 . Please help me , thank you
