Brian Crower Mazda MZR Stage 3 Camshafts - Race Spec

If you're building a Mazda MZR engine for serious track use or drag racing, the Brian Crower Stage 3 Race Spec camshafts are a key component to unlock its full potential. These aren't your everyday street cams; they're designed to make significant power when the engine is spinning at higher RPMs, making them ideal for dedicated race applications where you're pushing the limits. They work by changing how long and when your engine's valves open and close, allowing for a much larger volume of air and fuel to enter the cylinders and exhaust gases to exit, especially at high engine speeds.

Brian Crower is known for making well-built valvetrain components, and these Stage 3 cams are no exception. They feature a more aggressive lobe profile compared to milder cams, which is what allows for that improved airflow at higher RPMs. This means you'll feel a noticeable difference in acceleration and overall power output once the engine gets into its powerband. Because these are race-specific, you can expect them to be optimized for peak performance in a competition environment. They are designed to work with upgraded valve springs and retainers, which are often necessary to handle the increased valve lift and higher engine speeds associated with these camshafts. Installation will require careful attention to timing and potentially adjustments to your engine's tuning to get the most out of them.

Keep in mind that these camshafts are not CARB approved and cannot be shipped to California. For a dedicated race build, these Stage 3 cams from Brian Crower offer a substantial step up in performance, especially when paired with other supporting modifications. Ensure you consult with your engine builder or tuner to confirm compatibility with your specific setup and to dial in the optimal settings for your MZR engine.
