What Injector size to use with 185HP LS/VTEC ?

I have a 1995 Integra with a LS/VTEC engine with about 175 HP and doing some mods that would probably take me up to about 180 - 185 HP.

I currently use a set of 270cc fuel injectors.

Are these adequate for my application ?

If not, what size should I get - 310/320cc, etc ?

you dont need more then that until you add forced induction, then youll go big.

I have always heard that the 240s are good up to around 200 hp and then you want the 270s. 250 hp you would run 310s and anything more and you are running boost... :)
