So I want to build a N/A single. im going to use the d16y7 block, and the y5 head, the vtec-e. I want to get a cam and do some head work, for a hair more power. but anything i look up, only has shit for the y8. i know the vtec timing is off cuz the y8 is 8 to 16 valve vs. the y5, 12 to 16. is there that much of a difference for the type of cam? if so, please inform me.
