e30ftw 403 Report post Posted January 6, 2010 They're 17.5lbs. No gains on a stock motor what so ever. Quote Share this post Link to post Share on other sites

e30ftw 403 Report post Posted January 6, 2010 Yeah the difference is barely anything. Sometimes even decrease with the m30 AFM. Look around at it, alot of people say it's a waste of time. Quote Share this post Link to post Share on other sites
djs325 0 Report post Posted January 6, 2010 Easiest swap is either the M42B18 (318is) or M30B35 (535i) injectors, same size, same resistance, but higher flow, drop straight in, will need a tune though. Quote Share this post Link to post Share on other sites

turboprop 0 Report post Posted January 9, 2010 M50 injectors have a different spray pattern, 4 pintel, which atomizes the fuel better. Quote Share this post Link to post Share on other sites
pureboiracer 0 Report post Posted January 20, 2010 so say extractors, cia, cam and chip was already done, would m50 injectors help? Quote Share this post Link to post Share on other sites
e30ftw 403 Report post Posted January 20, 2010 depends what injectors the chip was tuned to be used with? Quote Share this post Link to post Share on other sites
