I have a SR20(JDM) with GA 1.6 pump. I have an Aeromotive FPR and would like some recomendations as to what pressure to run.

Mods are: 2" exhaust, JDM factory Headers, CAI, MSD 6 with Blaster SS, Unorthodox 4 Piece

I have alot of traffic here in Trinidad so how low could I run on these days and what should I run on Track days?
Thanks

The GA16 and stock SR20 pumps are the same. Atleast here in the states. Set the fuel pressure to 44 psi with the vacume line off the FPR. That should be fine for everything.

I have a jdm 1994 s14 sr20det with newly fitted fpr sard. I am asuming 44 psi is standard.

it also has exhaust, intercoller, manifold, hks acuator. I want to increase the boost to 1bar or 14psi. so how would this affect the fuel pressure. also dose any one know what the standard boost is for an sr20det. I think might have been increased before i bought it. afraid to drive it with out getting the setting right for the boost. I have it set at 44psi.
