bigger turbo, injectors, custom software, rods, pistons, FMIC, etc. etc. The funny part is that im still riding on stock wheels/suspension........ ok, its really not that funny. But my car is limping right now, I broke a bolt off that holds the wastegate on, I had to rig it for the time being. so one of these days I have to rip the exhaust mani out and take care of that....my car sounds like i went to ricer academy right now......
