You have a great point that it isn't exactly cheap, so my goal is to try to figure out the required P/Ns and create a reference so we have all something to refer to if we want to do this mod.
The easy part seems to be the M3 steering rack assembly, as this can be gotten for a reasonable price off a salvage or ebay M3 partout.
What I am more curious about is the 1M power steering pump. Since 1M production numbers are quite low and it was only used on the 1M (as far as we know), the pump would be the expensive part as it would be sourced directly from OEM.
Aside from the pump, what is actually required for this swap? Hope we can try to piece together a reference guide.
I've pulled up the RealOEM parts diagrams, and see that the pump itself has pulleys and such, other parts around it. I wonder if we only require the pump itself, and can swap the pulley and other parts from the original 335is N54 pump.
If not, I don't see it being too much of an extra expense, but would be nice to figure out more.
