Apex 693 Report post Posted May 7, 2008 What’s the difference between a motronic head and a non motronic head? Sorry to Hijack but im building a plan and was just wondering the difference. Quote Share this post Link to post Share on other sites
Jeddy 0 Report post Posted May 7, 2008 What’s the difference between a motronic head and a non motronic head? Sorry to Hijack but im building a plan and was just wondering the difference.All m20 325i's are motronic. My understanding is there isn't any but maybe wrong. I think with m20b20's they used the same 731 head when they switched from Jetronic to motronic.Apex are you going 2.5 or 2.7? Quote Share this post Link to post Share on other sites

I was just wondering what the differences were on Facelift models mechanicals. Quote Share this post Link to post Share on other sites
tire 10 Report post Posted May 7, 2008 Don't quote me on this but... The facelift ones have motronic 1.3 whereas the pre f/ls are 1.0? Oh look what i just found on wikipedia: "he German version of the M20B25 produced 170 hp with a catalytic converter and 171 without. It featured "885" head with larger ports and valves, 84 mm (3.3 in) bore, and 75 mm (3 in) stroke. Most significantly it had redesigned pistons and combustion chambers for better power, more resistance to detonation and higher thermodynamic efficiency. It was equipped with Bosch Motronic 1.1/1.3 Adaptive fuel injection. With a minor modification that adjusts the idle speed of a cold engine, the 325i fulfills Euro 2 emission requirements in Germany, resulting in a lower tax compared to Euro 1 (as of 2005)." So 1.1 for the pre f/ls, 1.3 for the f/l. Quote Share this post Link to post Share on other sites

Its very useful.Either head should be fine. Are you chipping or ms/linking for ecu? Edited May 7, 2008 by jeddy Quote Share this post Link to post Share on other sites
antony 0 Report post Posted May 7, 2008 Is exactly what I'm doing. Can answer questions, but start a new thread, as it is completely off topic Good luck finding what your after, shouldn't have much trouble finding a m20b25 head. If you decide on a m50b25, get non-vanos one from an e34. Quote Share this post Link to post Share on other sites
