BMW S14 2.3L Engine with Getrag 265 5-Speed Gearbox – E30 M3 (1989)

Available here is a BMW S14 2.3-liter inline-four engine paired with a Getrag 265 five-speed manual gearbox, both reportedly removed from a 1989 BMW E30 M3 showing approximately 102k miles. This powertrain was acquired by the seller around five years ago and remains a well-preserved example of BMW’s most iconic M-series drivetrain.

The S14—developed for the legendary E30 M3—features a cast-iron block, a 16-valve aluminum cylinder head, and dual overhead camshafts, topped with the distinctive black crinkle-finished “BMW M Power” intake plenum. It retains its Bosch Motronic engine management system, wiring harness, and exhaust manifold, making it an ideal candidate for an authentic restoration or period-correct performance project.

The Getrag 265 gearbox, renowned for its strength and precision, remains mated to a clutch and flywheel assembly and includes a partial shifter linkage. Together, this combination delivers the engaging and mechanical driving experience that defines the original M3.
