Doesn't the S54 also have an Aluminum block? No. That's why I'm interested in the physical differences between them and peripherals like girdles and how the mains are secured (2 bolt, cross bolted, etc).
Or is is the crank itself? Are there significant differences between the M54 and S54 cranks besides stroke? Journal sizes, counterweights, overall weight...
Anyone ever put the rotating assemblies on a scale?

I'm just curious... it seems like there could be so much potential but much like a viable end user flashable tuning solution there's nothing out there.

Also, Rob: I see we're pretty much around the block from each other. Are there any BMW meets in the Mid-A coming up? I'd like to head to VIR at some point this year.
I'm no S54 guru, there are many other E46F forum members way smarter than me on that subject, but to the very best of my knowledge it's a cast iron block, not an aluminum alloy like the M54 motor.

As to VIR: The May 12-13 SCCA Double MARRS (Mid Atlantic Road Racing Series) Race #2&3 (VIR), well I'll be in Hawaii on my Honeymoon.
