    What part does what?

    Thought this may be a good idea for others as well, to explain what certain things on the z20let engine do. I'm sure people will know what some bits do, but not others.. so may be a worthwhile thread!

    so would be good to list the number, and then the part name, then its function, and then people can add or ammend what others put, sort of in this style:

    Image Number 1
    1: Part Name
    2: Function
    3: Anything else?

    p.s hope members dont mind me using their pics

    and if anyones got anymore time etc to pick any other parts, may also be useful:







    Regal Phase 3.5,VXR Turbo,VXR AFM,VXR Injectors,Courtenay FMIC,Dbilias Flowmaster,Regal Precat,Miltek exhaust,Lightened Flywheel,Uprated Clutch,Denso Plugs,Veccy Pipe,Eibachs,308mm Discs

    14 - This is the start of the turbo.

    15 - This is an aftermarket dumpvalve, just below the hose.

    16 - The spark plugs are under this cover

    17 - This is an aftermarket airfilter, but this is where the normal air filter sits
