   Good luck man, I couldnt find ring gap for love nor money. In the end I had no option but to just put them in and hope for the best.

   Piston ring gap should be between 0.25mm min. to 0.45mm max.

    piston ring will depend very much on type of piston and spec of engine
    n/a will be less gap than a s/c or turbo engine and forged pistons will ahve different gap than cast pistons
    I certainly would not run a gap as close as the minimum gap suggested by paulogt.
    even the maximium is close for a boosted car making big numbers
    and also top ring could be different than second and oil control ring--ask your piston maker--and tell them what you are doing
