Default Injector question

I have a 96 trans am and I swap out the lt1 for a 5.3 lm7 and I am putting a 76mm turbo in it. What size injector size so indeed maybe a 42lbs or 80lbs? And what is a good brand with injector data?

We would need alot more info to say exactly what injector, but its not just the injector. Youd also need a good fuel pump. We have all the racetronix from 255 (600rwhp) to the single 340 (about 800) to twin 255s etc. Youll need a good pump. After that even a 60lb injector would be fine if you are using an adj fuel pressure regulator. We carry MANY brands.
If you want to shoot me an email we can go over everything youre looking for and an your build, we can get you everything you need!!

I have a single 340 fuel pump to install. So I should go with 60lb injectors? What is a good brand to get that has a data sheet for I can input the info for the hp tuners and for the fuel Regulator all I have is the corvette fuel filter with the built in regulator. I think it is set for 58 psi. Should I stay with that or think about an adjustable fuel pressure regulator?

what fuel will you be using and what is your power goal?

you can work backwards from there to calculate flow requirements.

i would switch out that corvette regulator for either the stock truck rail type regulator or boost ref'd regulator.

My power goal is around 500-600 and it is in my trans am so the truck style intake and fuel rails won't fit. What is a good brand for adjustable regulator for boost?
