i started to explain the whole i-vtec thing to my friend, because he just got me confused with exhaust overlap, vtec on intake cam or exhaust and i dont know a lot about the k20a3. but i remember this really good post a couple months ago, with EVERYTHING you would ever want to know about the k20 engines.

i searched for it, but nothing came up. the title was something like "what is i-vtec"

or just "i-vtec?"

 

never mind, i found it.

it didnt answer all too much.

now i have a couple of retarded questions.

being as that the k20a3 only has VTC on the intake cam, is it the same with the vtec, or is that both cams?

does the k20a2 have vtc on both cams, im assuming its a yes.

and what about the k20a? same as k20a2, just a port and polish, high compression pistons, and a more agressive cam profile?

 

yes the k20a2 has vtc on both cams

k20a3 only has vtc on the intake side
