What size injectors should I get to see the max potential of my evolll turbo considering I only have a rewired 190lph fuel pump? I already know that i'm going to have to get an safc to control the larger injectors.

I am pretty sure 550's will be enough for anything you might be able to do with the evo3, at least I think. But I know for a fact that 650's are more than enough for it.

650's

How many psi's can the evolll efficiently push with the 650's?

Psi is not the right way to determine when you will max out injectors. Pressure = heat, airflow = power.

You need to look at airflow numbers to determine if your injectors can max out a turbo. The EVO III at it's peak is said to push 44lbs/min, although I doubt any of us will get there.

Kevin's website has a spreadsheet for calculating the max flow rate of any injector. www.posracing.net .

I am running 19psi on 650's, reaching a peak airflow of 33.8lbs/min on a cool night and have no problems.
