Camshaft selection has a direct effect on how an RB20DE(T) delivers power and response. The Tomei Procam Camshaft Set (part number TA301A-NS07A) is a matched intake and exhaust pair designed for the Nissan RB20DE(T), featuring a 272° duration and 10.25 mm lift solid profile intended for higher-output applications.
Tomei’s VALC profile (Velocity, Acceleration, Lift, Control) is engineered to open the valves more effectively and increase the area under the lift curve relative to many conventional designs of similar duration. This supports improved airflow and stronger power potential while managing valve acceleration and closing rates to help limit unnecessary valvetrain stress when properly supported. As a solid-profile set, these cams are suited to performance builds where precise valve control and increased lift are priorities.
These Procam 272-10.25 shafts are a capable upgrade for RB20DE(T) engines seeking noticeable mid-to-high RPM gains. Supporting valvetrain components and professional engine management tuning are typically required to realize the full benefit and maintain reliability. At Terra Firma Automotive, we supply this genuine Tomei Procam Camshaft Set as a serious performance option for RB20 builds. Choose Terra Firma Automotive for authentic Japanese camshafts that support capable, high-output RB20DE(T) engines.
