Possible Injector upgrade for sr red top? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ive noticed lately my injectors are are getting really loud. I THINK there may be a 255lph pump in the car, which Ive heard shortens injector life span on the OEM 370cc's. So my question is, can I upgrade to a slightly higher cc injector, even though my engine is a basicly stock setup? the only real aftermarket engine parts are the FMIC, BOV, Boost controller, and possibly an upgraded pump. And for those of you who are fuel delivery guru's, how can I truly tell my pumps a walboro 255? Am I going to have to rip the sucker out and read the engraving on it?
