sorry about that... just found my notes.
also, the AEM civic features a roller rocker conversion, which eliminates the VTEC function. this is due to less valvetrain friction and the fact that VTEC is useless in the realm of drag racing.
VTEC is great for fuel economy, when a loping idle and low rpm efficiency is important... but fuel economy is not of a concern on the race track.
thank god someone agrees with me! the other day i was argueing with some kid with a v-tec civic that if you want flat out performance, v-tec is just a fuel saver, but if you need a daily ride thats when its a performance upgrade. I think JUN also makes a similiar kit.
