OEM FP would be sufficient.... and 20 psi on a vtec motor.... is not OEM specs. should not be either on a stock FPR when doing a frankenstein...--------------------------
LoL i dont know what he fuck i just typed. But What i ment was your FP should not have been at 20 psi the stock fuel pressure should be more then enough *but If it is was at 20 psi then yes.... like someone above me said change your FF before you buy and put on a adjustable FPR. I honestly would not waste my time of a AFPR on a stock motor.
35 to 40 is what a normal FPR would read with Vaccum
