KF_Colt Posted December 30, 2019 Share Posted December 30, 2019 (edited) Hey y'all, I have a 1981 280zx NA that I slapped a turbo and carb onto in a blow through setup. I'm using a Holley 350 street avenger with nitrophyl floats, main jet extensions, manual secondaries etc. My question is, I have a fuel pump that puts out 7 - 10 psi at 30 GPH, and a FPR that is not boost referenced from a Holley 12-803 that limits between 4 1/2 and 9 psi. Can I keep this fpr and not have to buy a new one? I'm absolutely fine with running more rich to sacrifice power but being safe. I haven't changed out the Jets at all and don't want to run it until I know the answer. Running about 6 - 7 psi of boost Edited December 30, 2019 by KF_Colt Quote Link to comment Share on other sites More sharing options...
