Si i-vtec works the same as SOHCvtec??
ok i've been wondering this for a while now, and i know the k20a in the civic SI has the i-vtec system and i read up on it and from what i know the only vtec part of it is on the intake cams and not the exhaust cams. And I know that the SOHC VTEC motors vtec only activates the intake valves rather than both. so in a sense the si i-VTEC works just like the sohc vtec, at least for the vtec part of the whole matter. correct me if im wrong, I just want to know if what im inferring is right or wrong. thanks. all feedback welcomed.

Re: Si i-vtec works the same as SOHCvtec?? (notec oldhatch)
its not even vtec at all. I refer to it as "fake" vtec because it only has 2 lobes. The only "real" vtec is the k20a2 (rsx type-s) and the k24a2 (TSX). When i say "real" vtec i am talking about how the original vtec work on the old models.
