Selecting the "right" injector
To the tuners and builders, yes I've done my research and check out the inject. calculator. But still don't seem to understand it, So my question is which injectors do you recommend for my build. I've had guys tell me different setups from 32# up to 42# injectors. I have the following setup in my Chevelle swap.
5.7 Ls1
Cam comp xer281hr-12
Intake 232/.595
Ex 234/ .598
112 LSA
Springs and titanium retainers to match
241 heads light port and polish job
Light milling of heads. I think .07 or .007? One of the two.
LS1 intake
GTO Ls1 cable TB (plan on porting)
98 vette MAF (I wanna upgrade if possible)
As of right now I have a 97/98 fuel rail (outlet and inlet on rail) but can get aftermarket if needed.
Also I'm gonna purchase a spectra fuel inj. Oem spec fuel tank from rockauto I hope the fuel pump that comes with it will work for my setup.
Thanks any and all advice welcome

The factory LS1 injectors were 28.8LB/hr @ 58psi (4bar).
If you got say 32# injectors, they would be rated at 43.5psi; and you would be running them at 58psi....so they would actually flow 36.95LB/hr...which is plenty for that engine. I would most certainly not go above 36# @ 43.5psi rated injectors on that engine.

If you are sticking Naturally aspirated I would grab some 32# or 36#, certainly no larger unless you plan to do forced induction.

***Off topic but I also need to get a Map sensor. Which one do you guys recommend? part #'s?
Thanks
