Injector advice
I am working on a 1999 FRC project, need input on what size injector to get/which would be best. The mods to the car are as follows
COMP XR269 CAM
Bassani Longtubes
Bassani X pipe with high flow cats
Ti exhaust
Verman Intake
I have stock injectors which i doubt would cut it, I also have a set of simens 60lb injectors which i assume would be way overkill.

Try this calculator . . . .

But, remember these calculators use a fuel rail pressure of 43.5 lbs as a standard rate for calculations and your car has a fuel rail pressure of 58 lbs. If the calculator says you need a 36 lb injector you really only need about a 30 lb injector. Until you're over 500 crank horse power (approx 425 RWHP) your stock injectors will probably be fine. I think some people are running even more than that on stock injectors.

My tuner told me that stock 1999-2000 injectors are 24lb and they can't handle any power, but 2001-2004 and i think 1997-1998 all have 28lb injectors, and the 28lbs will allow you to make more power without maxing out the injectors. I changed mine when I installed my LS6 Intake and Vararam.
