Welcome! As your seen it’s been done but rarely as it’s not the lost cost effective for HP swap. The one done was built by numerous shops, but is possible. Not sure how open Dave and Kassel are about sharing their journey for free. I’m sure you could work something out asking them. As far as s52 parts being harder to find I don’t think that’s true. You can still find just about everything for that motor off any parts website and/or dealer. Hell BMW will still sell you new heads. A side swap I should have looked into more but needed my car back was an M54B30. There are very complete DIY for e30 platform with a much lower entry cost than n52 or S52.
