Fuel question

[Project D]

I have finally got most of my engine planned out. I will be running the stock T25 turbo with an HKS actuator and FMIC. Other than that, I am running a tubular manifold, turbo back exhaust, Apexi power intake, and some pulleys (shouldn't effect power too much). For fuel, I want to a walbro fuel pump and SAFC. Will I need to run 555cc injectors? I don't think I need to since I am keeping the car at 12 PSI but any experience is appreciated. Thanks in advance.

with the stock turbo maxed out, the stock 370's are at their limit bt dont need to necesarily changed out.
