Changing Injectors

[justin911]

hey peoples

ive got some s15 480cc injectors for my r33 gtst. They came already installed in a r33 fuel rail and are aparantly only 6 months old so i think there in good condition. anyways Is there someway i can clean them myself at home while there installed in the fuel rail (which isnt in the car) ?? Is there anything i should do to them before i install them ??

once the fuel rail is installed, are the values below correct to work out the injector correction / latency to enter on the pfc ??

stock rb25 - 370cc / 0.528msec

s15 - 448cc / 0.584msec

370 / 448 = 0.82 * 100 = 82.5

0.584 - 0.528 = 0.056

??

Oh yeah i've also got a sard adjustable FPR setup, will i need to do anything with that when i put the new injectors in ?? like disconnect it or kick it something ?? Im going to be driving to the tuners straight after there installed but is there anything else i should do or know so i dont blow the ol girl up ??

thanks

just keep the fpr in there, make sure the pressure in the rail is ok and there shoudnt be any probs at all, if you read r33paul power fc faq it will tell you bout how you might have to adjust the inj value slightly and tell your tuner the value.
