Injector selection questions
Injector selection questions I'll be putting a cam in my 2000 TA in the upcoming months and my stock injectors are already at 99% at WOT. Right now the car has LS6 intake, ported TB, LTs, and a Vig 3600. Based on my calculations at the FIC site, a 32lb injector would work, but 36lb would be better and give me more room for any future mods (e.g. small shot of nitrous). What injector would you all recommend w/o having to change out my fuel pump now? I inevitably seem to change rears once a year for one reason or another so I'd like to be able to put off doing the pump until I'm down there for another reason. Certainly, I'd change the pump before I did nitrous, but I don't see myself doing that for a long while anyway.
So, here are my real questions:
1) Are EV6 style injectors REALLY that much better than EV1? Am I going to see any difference on my ~400hp car and up until what rwhp value would LS2 injectors last me? Are they 32 or 34lb?
2) 42lb injectors come up on the classifieds all the time, is there any way I could run these without immediately doing a fuel pump or is that asking for trouble?
and finally 3) If I do run an EV1 style injector is there any particular difference among brands (Fast vs Racetronix vs Ford motorsports)?
Actually, I do kind of have a 4th question. I understand that the fuel pressure will change how much the injector flows. So a 42lb @ 43.5psi is about 50lb @ 60. Where does knowing this come into play? FIC's injector calculator tells me what injector I need at 43.5 and isn't that the standard that they are rated at?
Thanks for any input you all have!
