the first vtec engines in america were the 91 nsx's followed by the 93 preludes, then the GSR's in the 3rd gens i believe. you guys are hearing your secondary runners opening. vtec on sohc engines is very minimal... even on a stock h22... all you really hear is the runners opening at 4800 then at 5100 when the vtec cam lobe enables there is the power increase. vtec is not like a turbo or anything. do some reading in the high performacne section on vtec. it is not a save all power feature, expecialy for the sohc engines.

oh and vtec engages at 5150rpms on a h22, and somewhere around 5.5-6 for b16's and b18's i beleive. s2k's are also about 6k rpms.
