    Piston/Cyl ID Help

    Can someone tell me what type pistons and cylinders these are, taken from a 1965 911, previously rebuilt by PO. The photo of cylinder with 6 in triangle followed by 30- 0 is not the cylinder from which the piston shown was taken (this cylinder has the most clear marking). Thanks in advance for any help!

    Looks like a normal 2.0 piston. Cast iron cylinder with height group 6.

    Thanks Gled49 -- so the PCs are original to the engine? Mahle? And the 4+ marking on the piston signifies what? (Other pistons have other designations.) Thanks again for the help!

    Those are 2.0T pistons & cylinders, so are not original to your 65 engine.
    The "4+" is a Kolbenschmidt casting reference.
