I run a 318i and I was actually wondering if there was any way to rebuild the block with higher compression parts to make more power. I've got what I think is the m10 Single cam unit engine and I'm thinking about swapping for the l6. However if I can find some ways to make my engine perform better while I have it, that'd be awsome.

Also, does anyone know if its the same L6 in the 525 series? Because I found one of those at a junkyard that I was considering. Anyhow, I gotta run. lunch is over.
