If I am not mistaken, fuel pressure on a stock b18c1 is between 40-44 psi. You can probably bump that up without having too much trouble. Do you have an A/F ratio gauge yet? If not, you maybe want to invest in one. JMO!
i have the GSR head (ported & polished) on a LS block...last time i checked not even two weeks now..
my fuel pressure was 47psi...
i am takin for a 500 mile ride, them i will check the plugs and see if i am running rich or lean///
An air fuel gauge could mean the life of your motor, I don't think your going to be running to lean but running rich isn't exactly good either. I would infest in a step up on injectors too if you have the pressure you might as well follow up on some volume.
