BMW M10 2.0L Engine with Kugelfischer Mechanical Fuel Injection – 1972 BMW 2002 Block / Rebuilt by Catalpa Street Garage
Offered for sale is a BMW M10 2.0-liter inline-four engine featuring a Kugelfischer mechanical fuel injection system, built by Catalpa Street Garage of Santa Cruz, California in 2010. This engine combines the proven reliability of the original BMW 2002 M10 block with a later-model 121 cylinder head, delivering both authenticity and upgraded performance potential.
The M10 engine, originally designed in the late 1950s by Alex von Falkenhausen, became the foundation for BMW’s motorsport success and later evolved into the legendary turbocharged units that powered Formula 1 cars in the 1980s. Known for its cast-iron strength and lightweight SOHC aluminum head, the M10 remains a favorite among vintage BMW enthusiasts and restorers.
This particular engine was acquired from Bring a Trailer (BaT) in 2022 and presents in excellent cosmetic and mechanical condition. It includes a Kugelfischer mechanical fuel injection system, silver powder-coated intake manifold and valve cover, and all major accessories needed for installation or restoration use.

Why This Engine Stands Out:
The BMW M10 is the heart of BMW’s classic era — simple, durable, and race-proven. This specific unit has been professionally rebuilt and enhanced with a Kugelfischer injection system, offering period-correct performance and reliability for vintage BMW projects. Its complete setup, from intake to oil sump, makes it an ideal choice for a BMW 2002 restoration, a retro-mod build, or a collector’s display piece.
Engines built to this standard rarely surface on the market, especially with documented provenance and professional craftsmanship.
