Nissan 370Z Forum - View Single Post - Running higher Fuel Pressure than OEM Spec

tnt0823 · 05-26-2016, 06:29 PM

Hello
I did a few search on the subject but couldn't find a definite answer.
Base on FSM, ~51psi is the OEM spec for fuel pressure at the rails.
Im going to be running around 58 psi from my current pump+filter setup to the fuel rail, would this cause any problems?
I know running the engine rich will shorten the life of Cat and emission component, but wouldn't the ECM compensate for the addition fuel from higher pressure?
Just trying to avoid adding FPR and fuel return system, since i have no plan for FI or making much more power in the future.
Any help is appreciated.
