hi guys i have a b16 powered crx. i was thinking of spending some money on a few upgrades. i searched a bunch. im gunna get an intake mani of some sort, prolly skunk2 or edelbrock. also a cold air intake, probably aem hybrid. if i buy a intake manifold, it doesnt have to be port matched? i know my tb will have to be bored, but to what size? also, do i have to buy a gasket(s)? i have a dc 4 2 1 header already, anything else needed for these upgrades? tahnks
