pressure should be 43.5PSI.... i think they didn't go to like 55psi until 2000?

flow..... 19lb/hr minimum

i have a newer FPR i can put in, what LB/hr would that make them at 55psi?

edit: i need to know if these can be made to work for a 3500 engine, or if i should buy new injectors?

here you go all your injector info needs.

it would make them 22psi which is what the 2000+ ones are.

[hookdonspeed]

is that enough for a 3500 or should i upgrade them?

[robertisaar]

should be, assuming you don't go absolutely nuts with it. stock, fine

[mr.rogers]

are the 2000 + injectors better quality? the one i had from a 99 were big and ugly, i got a new rail and injectors from an 01 ga the other day and they look completely different.

[robertisaar]

they are different, but better quality? i don't know about that, they're newer, and designed for higher pressure, if that means anything for you. i believe they use different connectors for electrical as well...

im staying stock for now, im turboing next summer, but i was planing on a new set of injectors when that time comes.
