RE: What size Injectors Do I use ?
i bought and installed one. works great, costs less than a BBK unit and does the same thing and i think they flow a little better. just a turn of an allen wrench and you can adjust pressure, you MUST get a small gauge with it too (buy a gauge kirban combo on ebay for 80 bucks) fuel pressure regulator is a must.

nice heads teal..
I'm running 9lbs of boost and using 42# .
The only thing with that size injector is the computer has a hard time controlling them so you need to do a dyno tune for best performance.

that depends on if you use an fmu.......I use 42's and a sfmu but 42's work great on 10 spi bad thing when going to 42's is idle issue so a chip is a must!......if you want no issues then the 30-36# pound ones with a fmu this will work with no chip but one is need to fine tune your set up and get the most out of it and be safe as well
the kirban unit is one of the best..there like 65.00 new....

I dont know if you guys know this but stock 19lb injectors on a stang will support 6lbs of boost. Its easy to figure out the rest. I'd say either 24lb or 30lb injectors. Anything higher is overkill. 42lb injectors support 700hp, I doubt you'll be making that kind of power, because your more than likely to crack your block if you tried.

Did you use that link I sent you? I estimated 350hp with 10# boost and got 30# injectors you would need. How much HP do you estimate you have? Be honest now.
Notch4949, a 700hp engine with the same amount of boost would need 55# injectors.......according to that handy calculator I posted earlier.

I run 30 lbs injectors with 55 lbs of fuel pressure. No problems here. Just make sure you have enough pump to get the fuel to the injectors. Your motor will only use the fuel it needs.
