Improving camshaft profile is one of the most effective ways to unlock additional response and power from the RB26DETT without requiring extensive supporting modifications. The Tomei Poncam Camshaft Set (part number TA301A-NS05C) features a 262° duration and 9.15 mm lift on both intake and exhaust, offering a balanced upgrade for the Nissan Skyline R32 GT-R, R33 GT-R, and Stagea C34 260RS.
Designed as a bolt-on friendly performance camshaft, the Poncam profile delivers noticeable gains in mid-range torque and top-end power while maintaining a stable idle and good drivability. Valve timing is pre-set for straightforward installation, and the relatively moderate 9.15 mm lift allows the cams to work with the factory valve springs in many applications. This makes the set particularly well suited to vehicles running stock or mildly upgraded turbos where improved airflow and sharper throttle response are the primary goals.
The Tomei Poncam represents a practical first step into performance camshafts for RB26 owners who want measurable results without moving to more aggressive, high-maintenance profiles. At Terra Firma Automotive, we supply this genuine Tomei 262-9.15 Camshaft Set as a proven upgrade for R32, R33, and Stagea 260RS builds. Whether you are refreshing a tired factory setup or pairing the cams with supporting bolt-ons, these Japanese-engineered camshafts provide a reliable path to improved engine character and performance. Choose Terra Firma Automotive for authentic Tomei components trusted by RB26 enthusiasts.

Strict phase angle tolerances minimize the risk of valve timing issues and ensures each valve opens and closes precisely. Tomei research showed that some camshafts from other manufacturers had more than 5 degrees difference in the phase angle! This makes it near impossible to achieve the correct valve timing.
