there is A LOT you can do to boost hp... intake and exhaust are 2 of the most common and the easiest... and easiest to find for most cars.you can also add headers, cam, cam gears, pulley kits, intake manifold, throttle body, upgrade your ignition, port and polish your head...like i said... there are a lot of ways to add power... and you dont have to dish out 3k for a turbo
