I am getting ready to do a mild HCI on my car. Planning GT40P heads, Cobra intake, And maybe a E303 cam or a Trick Flow Stage 1. I know I will need to upgrade to at least 24lb injectors. So I have 2 questions. First if I go larger then 24's and my engine does not really need them will it hurt. One of these days I would like some boost or NOS and I would have to upgrade again. I wonder if I could just get away with 30's or 39's? Second I have a chance to get a set of Rochester 24lb injectors that have the 6hole spray nozel. Fully reconditioned with a lifetime warentee. Does anyone have any experiance with these injectors? Are they any good? I can get the whole set for $100. What do you guys think.
