Possible to swap M2 N55 into F21 M135i???
Hello,
I had the catastrophic oil starvation issue on my 2012 M135i so i'm looking for a rebuild. There might be possibility for getting an low mileage M2 N55 complete engine for similar price of a rebuild so I am considering the swap. I imagine will need the ECU / harness, downpipe might be different... But otherwise, might anyone have more information if there might be additional components that would hinder this idea? For example not sure if there is some additional oil cooling... Another issue for considering this is that it seems this problem with engines siezing is due to the stock oil pumps, so a solution is to add the components from S55 engine. However that involves adding 2 oil pumps and changing oil pan, so this adds a significant amount to the rebuild of an N55... |
