They both are the N55B30A variant. I know the M235i N55 has the forged crankshaft. Can I use an M235i N55 instead of a 335i N55 as a replacement and how much more work would it be to get it working?

Funny enough i spun a rod bearing on my M235I N55 a couple weeks ago, so much for forged internals...
One of the shops i called when inquiring about sourcing an engine told me that the N55 from a 335i would be a swap option and "should drop right in" mind you only one shop told me that of the 4-5 i called in my area.
I know the Xdrive N55s have different oil pans than non Xdrive N55s. so be careful with that.
Do we know if the S55 oil pump is compatible with the N55 Xdrive oil pan? S55 oil pan apparently doesnt fit on my N55 due to said Xdrive
