Please note: All camshafts must be installed by a professional engine builder, using the provided camshaft specification sheet. The builder is responsible for verifying piston-to-valve clearance and setting engine timing according to the cam card specifications, not the factory settings.
For over 15 years, our 5150 Turbo camshafts have proven their reliability and performance in both our vehicles and our customers’ builds. Through extensive testing and comparison, we’ve fine-tuned these cam options to ensure you get the best results in high-performance applications. All our cams are brand new—no core exchanges or re-grinds necessary, providing an easy upgrade path for BMW M20 turbo builds.
Cam Options and Recommendations
The STREET / DRIFT option exhibits impressive versatility, catering effectively to street driving, circuit racing, time attack, and mild drift applications. It delivers quick spooling and enhanced throttle response for both ON & OFF throttle driving styles. This camshaft is frequently favored for vehicles producing horsepower ranging from 450HP to 800HP. We strongly recommend using a high-performance valve spring kit with this option.
For the most extreme performance requirements, the DRAG RACE option comes into play. Designed for cars producing 900+HP and equipped with high boost, this camshaft is tailored for aggressive driving, drag strips, big turbos, and high RPMs. The power band is shifted to mid and high RPMs, although it sacrifices a little spooling. This cam requires a high performance valve spring kit.
If you aim to increase RPMs to 8500-9500, the solution is in transitioning to solid lifters. Don't hesitate to discuss your engine build with our experienced advisors at Sales@5150autosport.com
