Need help here, what would be the best fuel pressure setting on a high compression motor with a upgraded fuel system, pump, injectors, filter, etc. The motor is N\A, D16Z6 block, with a D16Y8 head.

Thanx for the help ahead of time.

Assuming you have a fuel pressure regulator and a fuel pressure guage, the next item you need is a air/fuel ratio guage. Even an in expensive one (about $40) will get you in the correct ball park for fuel pressure to get the correct fuel mixture for your engine.

On my D15A3, I had to reduce my fuel pressure when I went to larger Integra injectors and then increase my fuel pressure when I added a larger throttlebody. The idea is to keep your engine at the correct mixture of about 14:1.

no more than 50 psi i would think so... a stock d-series motor is i think around 32-38 psi stock.
