Hi there ive got a 328 e46 on a 1999 t plate with the m52 engine. it is totally standard and done 90000 miles. im interested in either turbo or superchargeing it. and just wondering which would be best/easiest? also what would have to be done to the ECU ( ive herd you can just disconnect the air mass meter!?) would the standard injectors be ok? any help would be great thanks.
