would be fun to build a M30 with S38B38 crank and some bigger bore pistons with decent CR, 280 odd cam, proper exhaust etc etc. Would do that before swapping a 3.2L M50 even if it cost more.89 E30 325is Lachs Silber - currently M20B31, M20B33 in the works, stroked to the hilt...

You have fun with that $1000 crankshaft in that $300 motor. I'd probably go for the full S38 before I did that.
I think it was a feeble attempt at humor (point being that the M30 is the bigger motor)paint sucksComment
