Would 30/lbrs be ok or to much?

Heres the combo

Gt40 Iron Heads
E-Cam with 1.7 RR - 526/526 lift
TF Street Heat Intake
73mm Mass Air
65mm Throttle Body
AFPR
255/lph Fuel Pump
Complete Exhuast


Now, I know 24/lbers would be the best, But I plan on eventually running most likely Nitrous. Or if I could afford it instead an A-Trim/Sc Trim or Novi 1000 with around 6-8 psi with a FMU.

30's are fine. They will also allow for future upgrades. Do yourself a favor, buy an adjustable fuel pressure regulator and gauge. That way you can dile things in a little better.

i would say stick with the 24#ers, they should be fine with nitrous, u can turn up the pressure when using nitrous. and u might need even bigger injectors for a supercharger but maybe not

From what I understand, if you are planning future mods, you could go even higher, up to 38lb without problems. The 30's would be fine, with no cold startup problems. Rick Anderson or Anderson Motosport advises that nothing short of 36lb injectors be used, because it precludes the changing of injectors with every mod you make, and is still great for the street.

The 30lbers will be fine but depending on how long you got till you might get the blower or nitrous I would go 24's...just upgrade later...

Lets put it this way you dont have to have the 30# but if you are sure you will go to 400 hp then why not? If not stay with the 24# injectors as they will be plenty without power adders or more cubes!
