Produced from 1990 to 1996, the BMW M50 engine is a straight-six, double overhead camshaft with four valves per cylinder. You can find this engine for a few different BMW models through the large inventory on eBay. The M50 series saw use in the E34 luxury car and the E36 compact executive car. A higher-performance version of the M50, called the S50, was also used in the E36 M3 and the Z3 roadster. Using an iron engine block with an alloy cylinder head, the iron is inexpensive and strong, while the alloy heads are lightweight and durable. As a DOHC engine, there are two camshafts inside of the cylinder head. One camshaft operates the intake valves and one camshaft operates the exhaust valve. The dual design allows for improved airflow into the engine at higher engine speeds, which improves the performance and efficiency of the engine. Overall, there are five generations of the M50 and three generations of the S50 engine that have seen use in BMWs.
