Powering some of BMW’s most iconic M cars, this 3.2-liter S54B32 inline-six engine and matching ZF six-speed manual transmission were removed from a 2006 BMW Z4 M Roadster. Renowned for its high-revving performance and motorsport-inspired engineering, the S54 features a robust cast-iron block, aluminum cylinder head, dual overhead camshafts, individual throttle bodies, and BMW’s advanced double-VANOS variable valve timing system.

Included with the package is the matching ZF six-speed manual gearbox complete with its shifter assembly, along with a Siemens engine control module (ECU), wiring harness, dual exhaust manifolds, and various ancillary components. Whether for a restoration, engine swap, or performance build, this complete S54 drivetrain package offers an opportunity to own one of BMW M’s most celebrated naturally aspirated powerplants.
