Car: '11 335i xDrive
Default Is it possible to swap 2015 N55 into a 2011 N55 - 12-31-2018, 11:12 AM

My '11 335i xDrive N55 crapped out (build date 7/2010). Assuming an N55 block is an N55 block, I purchased a low mileage used N55 from a donor 2015 335i xDrive (build date after 1/2012). I've been advised to return it due to incompatibility of the hpfp fuel pumps and the challenges presented in retrofitting fuel pumps.

Retrofitting my hpfp into the newer motor involves changing the vacuum pump as well. The big question is the difference in the chain tensioner used. I really cannot afford to screw this up. Any help is appreciated.

Mike
