would anyone know how to adjust fuel pressure? im looking to gain 30% over stock. worst case scenario i would have to replace injectors and possibly pistons, but i am tearing it down this spring anyways and building bottom to top. im just testing the waters...any other bolt-on suggestions besides turbo and nitrous? after the build im going turbo.....thanks guys!!

Upping fuel pressure is usually a bad Idea to try and get more fuel into the engine. The injectors will have a harder time opening and may even deliver less fuel than the injector at stock fuel pressure setting.

The rite thing to do is go bigger injector and tune.

I wrote this thing if you want to take a look.

:woohoo:

Any way if you want to raise fuel pressure get an fmu or adjustable fuel pressure regulator.
