Raise wrist pins allow you to run a longer rod. the wrist pin is physically higher up on the piston, sometimes into the oil ring. ---

talk to hycomp on here he had that pretty serious allmotor setup with the itbs. im pretty sure he tuned it himself on the street and was able to go pretty fast. he would know best imo itbs are a pain in the ass unless your trying to make some serious hp. but even then they still arent necessary. vinny made like 250+ i think on a reg manifold no itbs. once your getting into over 200whp na. thats some loot not to mention your gonna wanna be on racegas. now we are talking streetability but to answer your question TWM makes some sick ones i woudl look into them if you want some. they are all pretty $ especially for the gains you may or may not get ---
