Trying to determine if the M54B25 is different between 3's and 5's. The reason I am asking is that I may be in need of a decent long block for a 2003 525i. In discussing this with LKQ parts they list THAT car on a separate line than a 2001 325i. I am aware of what is hung on the engine is different between these two cars, but I am ONLY interested in the bare long block, not a dressed engine.
Harness and oil pan need to be swapped to the application. Longblock is the same.
