you can use a crx si and it will run good the integra has a higher redline and alittle more aggressive fuel maps. if i had a zc i'd carb it but's me lol.

one of the best mods you can do is the crx/civic si final drive in your zc tranny it will make the gears really close(not extreame) then do the i/h/e, also get a b series tb sence it's bigger.

 

a b series tb will bolt up? how much to they run? any moding?

and i am using my hr trani for now till i get some cash! the trani has a new cluthc so .... ill deal for now! thanks
