Higher-duration camshafts are a proven way to unlock additional top-end power and airflow on a built RB26DETT. The Tomei Procam Intake Camshaft (part number TA301C-NS05C) features a 272° duration and 10.25 mm lift, offering a more aggressive profile suited to higher-output Nissan Skyline R32, R33, and R34 GT-R builds as well as the Stagea C34 260RS.
As part of Tomei’s Procam series, this intake cam is designed with an optimized VALC profile that improves valve opening velocity and overall area under the lift curve, supporting greater airflow and power potential at higher engine speeds. The 10.25 mm lift and 272° duration place it firmly in the performance category, making it appropriate for engines that already have supporting modifications such as upgraded valve springs, stronger valvetrain components, and appropriate tuning. It is intended for builders seeking measurable gains beyond mild bolt-on camshafts.
This intake-side-only cam allows staged upgrades or pairing with a matching exhaust profile. At Terra Firma Automotive, we supply this genuine Tomei Procam 272-10.25 Intake Camshaft as a serious performance component for RB26DETT engines. Whether you are assembling a high-power street car or a track-focused build, this Japanese-engineered camshaft provides the lift and duration needed to support elevated performance levels.
