Stroker M20 Engines for Open Classes

When the rules open up, so do the possibilities. Our stroker M20 builds provide significant increases in torque, mid-range power, and overall drivability, ideal for endurance series or open-class racing where displacement, compression, and cam profiles can be optimized. If you want the strongest possible package within your class regulations, we’ll design the formula to match.

A Formula Built for Your Ruleset

Every racing series has different limits, and BimmerHeads ensures you get the most engine possible within those boundaries. We work directly with you to define the build spec that meets the rules of your class—no guesswork, no compromises.

Complete Crate Engines: Tested, Run-In, and Ready to Install

All BimmerHeads M20 race engines are available as turn-key crate motors:

• Fully assembled by experienced race engine builders
• Run-in and tested on our engine stand for compression, leak down, and oiling verification
• Shipped ready to install on a pallet to your shop or picked up directly from our facility

You get an engine you can trust: broken in, proven, and ready for competition.
