I am putting an Ls1 in a 300zx. I have set the car up to run on two stock 300zx fuel pumps. The ls1 from what I have read needs to operate at 57 psi of fuel pressure with the stock injectors. The problem I have is that my stock 300zx fuel pumps don’t like that high fuel pressure and screaming at me for it. My question then is, if I go to a bigger injector how do I know what to set my fuel regulator at? Is there a formula for this?
