i have a 98 gtp with 49,000 miles on it and is totally stock, perfomace wise n e ways. i would like to get some more power out of it but i am really tight on cash because i am in school. i was wondering what would be the best way to get the most power for 500 bucks. i do plan on camming it at some point and obviously a smaller pulley along with all of the supporting mods so what we be a good way to start?
