Yo honestly swap that ish, seriously and basically you sound like you don't know much - asking questions like this one, so i don't think your mechanically inclined but can be. I say you just learn as much as you can about a different motor set up, about weight reduction, bolt-ons, and how they work so then you won't ask these questions and you can determine on your own, because on here some people tell you if you don't know, but sometimes they laugh at you in the sense of pity when you don't know. So you should basically read about stuff you may be interested in and make your decision about what your gonna do to get your car going fast or faster..
