the m42 is a 1.8 liter and uses OBD-I while the m44 is a 1.9 liter and uses OBD-II. the hp ratings are the same but the m44 has a tad more torque. as far as those differences im not sure what else there is. __________________ Vince Carknard 1995 318ti Active Hellrot, 16" 5 spoke, "Fogged" airbox mod, Stromung exhaust, Bilstein Sports, BMW sport springs, 3.73lsd, others... |
