    Used RS Piston Dilemma- engine gurus please help

    I have the opportunity to buy a set of five, yes only five 90mm domed Mahle pistons with valve notches. I am assuming that these are the factory RS 2.7 pistons.
    I can get them cheap - is there any point in buying 5? Will I ever be able to buy a single?
    I can also get a set of good 90mm Nickie's cylinders from a CIS car. What are they worth and are they compatible with the RS pistons or J&E's?

    Im pretty inexperianced, so any help is appreciated.

    Also, is there any market for stray 2.0 liter and 2.2 liter "S" pistons and cylinders?

    If it was me I would go for the Nickies and JE's.(actually I did for my 2.8 S motor) This way you can run your compession up to 9.8:1 on single plugs as opposed to the RS pistons that are only 8.5:1.

    Nickies usually run about $2800 for a new set. JE's run about $1000.

    The RS sets are good call if your main focus is longevity and if you want to use regular gasoline.

    Price check:
    You can get a new set of Euro RS P+C's from Dart Auto for $1800.

    They had some scuffing on the skirts. Otherwise seemed fine with some carbon buildup on the crowns.
    I just hate to see them get pitched.
