Hey all, just want to know what the base fuel pressure is at the fuel rail on a 4AGZE?
Also what would be a good pressure to set it to? as i have an adjustable fuel pressure regulator.

Cheers
Cam

Good pressure to set it to - The stock pressure. I dont know what that is though, someone else will fill you in on it. Approx 48psi is the norm for most cars (from memory) though. Only reason to change it is a) upwards for a last ditch attempt at getting more fuel if you're stretching to it, or b) downwards if you have big injectors in and dont want to tune it too far out with an s-afc.

standard pressure for a 4age bluetop is approximately 35PSI + or - a couple, not sure if it would be any different for a ZE though.

bluetop 2.55bar
redtop/ze - 2.9bar
