    turns out the pistons in S65 are cast aluminum just like S54 and S85; see pg 49 of the BMW after sales training on the e90 M3
    it's also interesting how they use a normal oil pressure VANOS system instead of high pressure on S54 and S85.
    also keep in mind the MSS70 on the Z4M has 64million CPS in it's DME where MSS54 was 25 m.
    My contribution of some relevant M trivia

    Site won't let me post the link. You will have to google it. it's over at e90fanatics as a PDF.
    over 110 pages long; good reading.
    It is titled "Aftersales Training - Product Information. E92 M3 Complete vehicle"

    I think the pistons are cast aluminum. Rods and crank are forged, I'll update.

    that's why I posted. S65 pistons are cast, the crank and rods are forged just like the other M engines

    not just M engines either...
    yeah, my S54, M54, and M42 all benefit from forged internals. good stuff!

    S54 engine accolades

    This was a great read. I really appreciate the time you took to put this together. It has been a great resource for research I'm conducting prior to an e46 purchase.

    Hoping to contribute, I found this write up by the American Iron and Steel Institute, which highlights several different engines (circa 2004), and on page 5 they talk about the S54.

    I cant post links yet, otherwise id share. If you google "The World's Top 10 Best Engines Use Steel", it is the 1st link to the pdf.

    I do appreciate it greatly.
    For those interested, here is the link: The World's Top 10 Best Engines Use Steel. (This is specific to the point in time which it was developed. Therefore, some of the world's favorites were not in production at this point, which means to you that they are not listed (ie 2JZ, SR20DET to name a few).

    Wow, lots of errors on the S54
    - pics of valvetronic?
    - bucket tappets from the M54?
    - forged AL pistons?
    wrongo!
    makes me wonder about the info on the other engines.
    I liked reading the article though.
    Thanks for posting
