hi guys...need some opinion here..
i got an escort cosworth that has been fitted with 803 green injector, -31 actuator, and fuel pump. I'm gonna up the boost to approx 1,3bar (19psi).
Do you think I need to change the standard 3,5 Bar fuel pressure regulator into a 4 BAR? Or just use the standard 3,5Bar?
Thank's guys...
