From the factory an engine is usually equipped with a camshaft that sacrifices low-end torque and top end power to focus on smooth idle and fuel economy, neither of which are a primary concern in high performance or race applications. Upgrading your camshaft is the single most effective way to change how your engine behaves throughout the RPM range. The camshaft controls the duration, lift, and overlap of the intake and exhaust valves opening.

Tomei Type R camshafts were designed due to popular demand from end users who are looking at upgrading the performance potential of their GT-R while staying within the limits of recent street legal requirements.

Recent laws on emissions and exhaust noise was made stricter in Japan so to have a quieter car by running smaller exhaust systems raises the exhaust back pressure which greatly reduces the response and hinder performance. Tomei engineers then designed these Type R camshafts to suit the needs of those who need to keep such setup and benefit with performance gains.

Tomei Camshafts undergo a vigorous research and development process to maximize horsepower and reliability. All Tomei Camshafts are CNC machined to guarantee a precise fit and proper valve lift/duration.
