    Default FPR - 4agze same as 4age??

    Hey Guys,

    Just wondering if these two engines share the same Fuel Pressure Regulator, because my fuel pressure is decreasing when the car is revved and I think my FPR is fucked...

    everything is hooked up correctly, 100% sure about that...
    I've been told that the FPR's aren't the same but I could use a 4age one just to quickly test and find out whether my one is stuffed

    Yeah, you could. Just make sure no boost is used though (ie unplug s/c)

    Also by correct, the brown/red vsv is connected correctly right?

    From what I recall, surprisingly, the GE FPR is set to a slightly higher pressure than GZE.
