5150 S58 3.4L 2000HP Turnkey Engine

The Complete S58 Build — Without the Guesswork

Building a high-horsepower S58 isn't simply about buying expensive parts. It requires finding the right combination of parts, the knowledge and experience to build them correctly, BMW fluent machinists who understand the S58 platform, and the proper machining equipment to perform the work to the correct specifications.

That's exactly what we've simplified.

Instead of spending weeks searching for individual parts, comparing combinations, finding a qualified BMW machinist, locating the right machines, and worrying about whether everything will work together, simply click one button and let us handle the entire build.

Send us your S58 engine core and we'll take care of the disassembly, inspection, machining, assembly, and performance upgrades. Within our normal 4–6 week turnaround, you'll have a fully built, 2,000HP-capable S58 back at your door.

These engines have been tested and proven in demanding applications, including high-performance street cars, track cars, drift cars, and full drag-race builds.

Every 5150 S58 engine begins with a complete disassembly and detailed inspection of the customer-supplied engine core. Our technicians then fully machine, prepare, and assemble the engine using proven high-performance components.

Every detail is addressed from the oil pan to the valve cover. Gaskets, seals, fasteners, and critical components are replaced or upgraded as needed to create a complete, high-performance package engineered for serious horsepower and boost.
