Hello everyone! I am coming to you for advice regarding a 2002 Corolla S (5 speed) that I am going to look at today. I currently drive an 03 Civic and my wife has the 01 Corolla S (A/T). In purchasing this car, I am wondering what type of gains I can expect from the normal bolt-on stuff like Intake, Headers, Exhaust. Are the gains noticable? Also, I know there is a turbo kit out there for the 02 S (it's a TSI kit I believe), but does anyone have any experience with it? Are there any problems running that kit, and what type of psi can I run on stock internals? I looked in the stickie up top for a cat back exhaust, and none of the links there took me to a site that had one for an 02 S. Does anyone know of a brand? Thank you very much for giving any information you can.
