M44 into M42

[1991 E30 M42]

I have M44 .50 over pistons, connecting rods, and crank shaft than I want to put into an M42 block, but I dont know if it would work. Has anyone ever done this? Im pretty sure it should work, but I think the M44 has a longer stroke.

yes that will work just fine and make decent power as well.

What is the displacement of the M44 and the 2.1 liter configuration. They are both in the E36 318is. What are the bores and strokes involved? I thought the M44 was simply OBDII.

The M44 from factory has a 1mm larger bore than the M42
