    VXR/Zlet fuel rail

    ive got both the Z20let and VXR fuel rails and it looks like the fuel pressure regulators are the same.

    Both have these numbers on; 90411542

    can anyone confirm thats the fuel pressure regulator?

    Depends on what state of tune you want Lee - If you are not going for big power (280bhp plus) then either would be fine.

    As long as your map is set up with the regulator you are going to use then there are no problems.

    The Z-LET is 3.5 bar and the other 3.0 bar
    Tell me what you've done, not what you're going to!

    Going for (Hopfully) the magic 300 bhp.

    Full spec should be:

    One of my FMIC
    Precat replacement pipe
    Sport cat
    Blueflame exhaust system
    1.9 TD airbox (Deristricted)
    VXR inj
    VXR AFM
    Sports cam


    Hoping that that lot with a remap would see 300bhp
