Injector size?
I am getting parts together to do my build while I am deployed to Iraq and noticed that I have forgot to get an injector upgrade.. I am clueless as to what size I should get and tried to search it but was unable to come up with much. The following mods are what I plan on doing:
TSP Ls6 stg 1 heads
ms4 cam
lg motorsports street version lt's no cats (already installed)
halltech cai(already installed)
slp loudmouth exhaust(already installed)
and probably a nitro dave nitrous plate kit.
ls6 intake
spec stg 3+ clutch(bought today for a great price at mvp motorsports)
I am looking to make 600hp at the most on the spray and think I will see around 430hp or so on the mods above and maybe shoot a 100-150hp shot on top of it.
So the question is, what should I do for fuel upgrades? I have looked at the racetronix kit for the fuel pump upgrade, is this a good kit to go with for that? What size injectors will i need? Anything else that I should look for on this build? Thanks for any help guys

I wouldnt go 30's you will probably be over 80%. 42's can be found pretty cheap. Also remember that these are rated at 43.5 psi. Our systems run 60 psi of fuel pressure and therefore 42 will flow more like a 50 lb injector at 60 psi. you should be able to get a set of lucas or ford injectors for under $300.

Is it just a 125 with everything else being stock or is it H/C/125 dry kit?
42# or 60# will be fine Im sure....60# will definantly give your more room to grow though

I will be doing a wet shot only like 100 or 150 at the most.. So would the 30#'s be fine or should I just go ahead and do the #42's just for room to grow. about where do the 30#'s run out of room?
