From sideways drifts to leisurely drives, the BMW M20 engine delivers. When you fit it to your car, it can cruise smoothly on the open road, plus it can power past slower cars when you choose to overtake them. It was introduced by BMW in 1977 and has a belt-driven SOHC design with 12 valves. Production of this engine ended in 1993 as the BMW M50 engine started to take over, with its four valves per cylinder. As it was produced over so many years, it has been fitted to various cars and comes in different variations. The cars include BMW's E12, E28, and E34 of the 5-Series, and the E21 and E30 of the 3-Series. They range from 2.0-liter engines up to 2.7-liter engines. At the upper end of the scale the BMW M20 engine produces up to 170 brake horsepower and up to 177 lbs. per foot of torque. With four models of the M20 engine to choose from, there is a vast inventory of the BMW engine available on eBay.Shop the extensive inventory of motors, parts, accessories, and complete engines for BMW!
