Engine Specs - S54 Rod Bearings - Wiki-DIY shows much greater rod bearing clearance than you have but tighter clearance shouldn't negatively affect oil pressure. OEM BMW S54 rod bearings are assymmetrical...I think blue ones on top of rod and red on bottom?
First is the S54 oil filter housing which bolts up the the M54 block with no problems and clears the intake manifold with ease. The first picture shows the housing and the P/S pump mounted. The P/S pump can be as complicated as you make it. VAC Motorsports sells the spacers you need to make the pulley line up perfect.

- The s54 cluser temp gauge runs a little over half way. Obviously my car does not over heat, only explanation I have for this is the s54 wants to run a little cooler than the m54 so the operating range on the clusters is slightly different (by probably a few degrees).

S54 OFH -> M54 again - but new questions - E46 Fanatics Forum
All of those considerations point to B30 swap over S54 swap. I'd originally planned on an S54 swap when I bought my car, but the daily driver aspect especially has pointed me towards the B30 instead, as maintenance costs are much higher for the S54 in addition to having fewer opportunities to make use of the extra power. I may end up supercharging the B30 down the road, and even then it would ...
