This combination yields the same weight as an S14 engine from an E30 M3...."The person who suggested the above was a mr. stuart mchenry...sort of an E30 forum sifu in the states ...his dad pete mchenry of precision performance in winston-salem, N.C USA is supposedly one of THE gurus of BMW engine swaps....I suppose the nikasil problem is a bummer but wouldnt somthing like this give at least high 190+ bhp and 200+lb ft in STOCK form..... a bit of work on the intake (I have read here and elsewhere some intake swap is a possible upgrade*) + some mild cam  + ECU + etc etc should up the power and torque to well over 200+ range.....M52 is definitely a more modern and sophisticated altenrative to M30 and in the above suggested form will even be in four pot weight range..... have your cake and eat it too??*shrick intake gives 14bhp increase apparently</blockquote>
