to be honest....vtec is only good if you're not turbo'd. cause once you smack a turbo onto a car, then wether or not its vtec, the turbo is gonna give most of the power anyway. vtec only gives maybe another 50 hp..give or take. but i plan on goin all motor so i'm gonna need the vtec. but overall, vtec really doesn't matter that much when boosted, but it does give you a LITTLE bit more power.
