BimmerFest BMW Forumturbo mb | BimmerFest BMW Forum&#;&#;Yes, the crank in the M engine is forged, and the bock is iron. The M compression ratio is quite high (.:) so a proper turbocharger installation will require the use of lower pistons, to reduce the C/R, unless you stick to a low boost. I have heard that supercharging the M has been more successful - don't know why, I would have
