    Im thinking of making an upgrade to my R56S wngine with forged pistons. Seems that the piston rings are in bad shape (consuming too much oil) so i probably have to open the engine and replace them, but once i do so why not put forged pistons in there. Friends have advised me for those two brands, Mahle and CPS but i have no idea which of the two is best! Any help on this and where from can i get them as cheap as possible?

    The Mahle are the better of the two!! When you figure that most endure racing/ GT track/ ect in the Eu are running the Mahle Piston... go with them.

    Just me.................................

    I don't think you can wrong with either choice. Personally, I went with pistons sourced from Revolution MINI Works on my rebuild.

    You need to figure out the reason the rings / pistons failed before buying a new set.

    The bore may not be in spec anymore. Don't buy parts until you know why they failed and what the true measurement is.
