    Wossner 85mm "S" pistons and Biral cylinders

    I have a new set of 85mm Wossner 911S pistons and (6) 84mm biral cylinders that will need to be bored to match. The pistons come with pins and retainers and the skirts have an anti friction coating from Wossner.
    Bought for a project that went another direction. $1200 for everything plus shipping and pp fees.

    Any idea what the compression ratio would be with a 2.4 crank?

    It would probably be around 10.5:1 but you could lower it by using a thicker cylinder base shim.
