anyone know anything about crower stage 3's? i just got a new set of crower stage 3's and the crower valve springs and retainers from a freind and was wondering what all else needed to be done to run these well. I have a B16a2 with I/H/E, what other upgrades would be recomended to run these cams? i know they are pretty agressive, crower recomends ecu modification and a vtec controler, what do you guys think? are they ok to run on an otherwise stock b16a2?
