i asked my mech. about what it would take b/c i thought about it for a while and off the top of my head it was a new throttle body, exhaust, fan and the list goes on...its about 3000 in parts, in addition to labor then you have the engine....if you were really that serious about adding major Hp you should think about a supercharger in addition to the chips and maybe a new exhaust and cold air intake...all of that would still be less than a new or used engine
