Mercedes-Benz M102.983 2.3-16 Cosworth Engine W201 190E 16V OEM Used

Overview

The Mercedes-Benz M102.983 engine is a 2.3-liter inline-four powerplant developed in collaboration with Cosworth for the high-performance Mercedes-Benz 190E 2.3-16. This engine played a key role in Mercedes-Benz motorsport history during the 1980s and became one of the most recognizable performance engines used in the W201 platform.

The engine is based on the M102 series but features a specialized dual overhead camshaft (DOHC) cylinder head engineered by Cosworth. This advanced cylinder head introduced four valves per cylinder, creating a total of 16 valves, which significantly improved airflow and engine performance compared to the standard eight-valve versions of the M102 engine family.

With a displacement of 2299cc (2.3 liters), the M102.983 engine was designed to operate at higher RPM levels while maintaining durability. The improved cylinder head design and revised internal components allowed the engine to produce approximately 167 horsepower and 162 lb-ft of torque in production form.

This engine became famous through the Mercedes-Benz 190E 2.3-16, a performance sedan developed partly to compete with BMW’s M3 in touring car racing. Because of its motorsport heritage and limited production numbers, the M102.983 engine remains highly sought after by collectors and enthusiasts restoring classic Mercedes performance cars.

This listing is for a used OEM M102.983 Cosworth engine, making it suitable for restoration projects, engine replacements, or performance builds involving the classic 190E 2.3-16 platform.
