BMW S14 Engine, Getrag 5-Speed Transmission & Complete Parts Package
Offered for sale is a BMW S14 2.3-liter inline-four engine paired with a Getrag five-speed manual transmission, removed from a 1989 BMW E30 M3. This package represents one of BMW Motorsport’s most iconic powertrains, renowned for its high-revving nature, robust engineering, and racing pedigree.
The engine reportedly underwent a complete rebuild before the seller’s acquisition in late 2022, including block machining, internal component replacement, and cylinder head reconditioning. It comes accompanied by an extensive selection of ancillary components, making it an ideal turnkey package for an E30 M3 restoration, motorsport project, or period-correct BMW swap.
