Default fuel pressure requlator questions....

Does anyone know the fuel rail pressure for a 98 2.5RS?
Does anyone know the fuel rail pressure for a 93 1.8L?

Does anyone know what happens when the warlboro fuel pump is run full on all the time with the 1.8L fuel pressure regulator on the 2.5RS motor.

I broke the 2.5RS pressure regulator sense port....

you really dont need a walboro fuel pump if your running an n/a 2.5, that may be overkill.

what is the problem your having?

do you want fuel pressure at idle?

well the walboro is in the tank now......

I haven't tried to start it yet. But before I do I want to know what to expect in terms of fuel pressures. I specifically would like to know if I should order another 2.5 pressure regulator.

It's all a bit up in the air really because I am running the 1.8ECU (auto) and its fuel maps. But we all know that by messing with the regulator and injector size I can probably acheive the bulk of the fuel mix compenstation without relying completely on the final closed loop 02 sensor compensation stage.

In any case it's good to know what is what re the pressure regulators.
