Alright here is the latest brain storm hopefully it has been done. A stock wrx injectors flow at about 275cc a stock sti injector flows at about 565cc. If you are running the '02 to '03 model of WRX what would be the complication of going to a the STI pink injectors and saving a bundle from buying the RC injectors and not wanting to modify my stock injectors or even have a reason for 850cc modified injectors in the first place (rc engineering helped me decide to go with a much smalller plan) my second question is (i've asked this before) How big is to big? With a 550 Walbaro, the afore mentioned injectors, a bov, gutted exhaust and a cold air intake how big of a turbo could I safely bolt on or should I stay stock and just turn it up tell detination and then back off a little bit?

stock injectors flow about 440cc..you could go with any vf series turbo and be safe..injectors are a must if you go with any turbo upgrade unless you plan to use 12-13psi or less
