    Just to add, the exhaust cam gear is different on the 2.0l engine. It runs at 102 degrees designated A102.
    So similar to the A100 cam gear that is on the 215hp cars.

      The 320is has the same cams as a standard M3, actually everything is the same apart from a shortened crank.
      The pistons and rods are different as well.

      Matt, PM sent. I apprecitate your offer. I'd love to take you up on it but I don't think I'll be able to make it up to you anytime soon. Unfortunately, due to work commitments it may be several months. I am very interested however.

        OK, To clear things up, according to ETK the pistons, Crank and Rods are different, the cams and valves are the same as an early M3.
        Suffice to say, dont trust what people tell you, go look yourself!
