But we can let you know when it's back in.
These cams were engineered as Unlimited-Series professional racing camshafts, built for Subaru engines producing extreme horsepower levels. Designed for full competition use, these camshafts maximize engine breathing by aggressively optimizing valve timing and lift, significantly increasing airflow, improving high-RPM efficiency, and supporting power levels far beyond what factory or conventional performance cams can achieve. They also feature dual lobe centerlines on both the intake and exhaust valves, enhancing flow characteristics and delivering maximum performance in high-boost, high-RPM environments.
We will optimize this camshaft to your specific racing needs, whether you compete in rally, time attack, endurance racing, or drag racing, ensuring the profile is tailored precisely to your powerband and competitive demands.
Upgraded valve springs are required, and the CJM Race Series Spring Package is strongly recommended to maintain precise valve control and reliability at elevated RPM and boost levels.
Break-In: A proper camshaft break-in procedure using high-zinc oil is mandatory to ensure long-term durability and optimal performance.
Professional Installation: Installation must be performed by an experienced race engine builder familiar with Subaru timing systems and AVCS calibration.
Fitment: These camshafts require adjustable cam sprockets on both the intake and exhaust, and the engine must be precisely timed to ensure safe and reliable operation.
