stock rail pressure for most hondas ranges from 41-48psi, get it in there and you should be good.

How much power are you trying to make? What kind of fuel management? You might want 60 psi. You might want 38. Your fuel pressure is going to be different depending on how much power you are trying to get out of you 450 cc injectors.

at this time 5psi boost, but changing the head gasket and arp studs ill try 8psi of boost, just wondering how much press i can set on the fuel rail with the hack vafc and 450 cc injectors for a good work of the fuel pump and injectors.
