Brian Crower Mazda MZR Stage 2+ Camshafts - Modified Engine Spec

These Brian Crower Stage 2+ camshafts are built with a specific lobe profile for modified Mazda MZR engines, meaning they're designed to work best when other engine components have been upgraded. The camshafts themselves are made from a solid billet steel, which is a strong foundation for the precise grinding that gives them their unique lift and duration characteristics. This isn't just a mild bump in performance; this is a significant change aimed at maximizing airflow through the engine, especially at higher RPMs. You'll notice a difference in how the engine breathes and pulls when you're pushing it.

Brian Crower is known for making well-built valvetrain components, and these camshafts are no exception. They're ground to exacting specifications to ensure they perform as intended and are durable enough for the demands of a modified engine. Because these are a Stage 2+ grind, they are intended for engines that have seen other modifications, such as upgraded intake and exhaust systems, and potentially other internal work. They are designed to work together with these other components to unlock more power. You'll want to make sure your engine's tuning is adjusted to take full advantage of the improved airflow these cams provide.

When installing these camshafts, it's important to follow the manufacturer's recommended procedures. This often involves checking valve spring requirements, as more aggressive camshaft profiles may need stiffer springs to prevent valve float at higher engine speeds. While these are a direct replacement for your stock camshafts in terms of fitment, the overall engine setup needs to be considered to get the most out of them. Remember, these camshafts are not CARB approved and cannot be shipped to California.
