    Supertech valve train upgrade questions?

    I have searched and read every past post on the Supertech valve springs and the kit that is for a VW VR-6-R32-24V
    Supertech will sell the sets or A la Cart individual pieces,
    The question is do you use the spacer that comes with the set that the VW uses or not?

    Is everyone still pleased with the set up?
    I only want to turn 8600-8700 rpms max with the Rotax ECU

    thanks,

    I dont believe you use the spacer but it would be good for some one to confirm.

    No spacer is used on the 4-tec.

    Correct, just the outer and inner spring and the retainer. No other fillers/spacers needed.

    I think they make a dedicated set for the 4tec, super tech does not recommend using the vw spring and retainer. I believe they will coil bind with a high lift cam hotbird just went through this problem

    springs will NOT bind. The retainter will bottom out on the seal *with a high lift cam*.
