wont get a lot of fans anywhere with body mods....drastisc i shoudl say. do a manual swap first before all if you want power. from there like veryone else said...turbo, swap, head work. what do you mean by serious power? 14.5 is fun.....15.0 is fun. 13.0 makes you cocky.....12 makes you basically invisible on the road...more cocky...11 gets you no girlfriends since you "spend so much time on your car and not me"
