👉 The only M50/M52/S50/S52 complete kit backed by a U.S.-based BMW race shop and in-house machining.
For over 40 years, VAC Motorsports has been the trusted name in BMW performance--delivering championship-winning engines, precision machine work, and American-made components to enthusiasts and racers worldwide. Our legacy is built on innovation and trust: innovation in designing solutions that push BMW engines beyond their limits, and trust earned by building motors that withstand the harshest racing conditions.
This BMW E34 and E36 M50-family engine build kit reflects that legacy. More than just a collection of parts, it's a carefully engineered system designed to transform your M50, M52, S50, or S52 engine into a track-proven powerhouse. Whether you're chasing serious horsepower for your street-driven E36 M3, preparing an E34 drift car for boost abuse, or building an endurance-ready E36 track machine, VAC delivers the ultimate foundation.
Unlike generic packages, VAC's kit combines decades of experience, in-house CNC machining, and real motorsport results. Before your kit leaves our facility, an experienced advisor will consult with you on piston specifications, compression ratio, and intended use--street, drift, drag, or endurance. That personalized guidance, backed by four decades of racing pedigree, is the VAC difference.
