    I believe that is true. All the 2.4 911 70.4mm crankshafts (T, E, S and RS) were forged and counterweighted....no difference at all.
    This is what my engine has.

    The earlier T engines had non-counterweighted and cast crankshafts I've read.

    You lost me at those non-Beru plug wires.

    Nice motor. Solid numbers. Enjoy!
