GSC P-D Nissan Skyline R32/R33 RB26DETT R15 Camshafts 276/278 Billet (Requires Head Modification)

These GSC Power Division R15 camshafts are built for the Nissan Skyline R32 and R33 models equipped with the RB26DETT engine. They are designed to significantly increase airflow into and out of your engine's cylinders, which is crucial for making more power, especially when you're pushing your RB26DETT beyond its stock capabilities. The R15 profile offers a 276-degree intake duration and a 278-degree exhaust duration, providing a noticeable bump in performance for street or track use.

Constructed from solid billet material, these camshafts are well-built to handle the increased stress and higher RPMs often associated with modified RB26DETT engines. The billet construction ensures durability and stability, allowing for precise valve timing. It's important to note that installing these camshafts requires modifications to the cylinder head to accommodate the new lift and duration profiles. This is a common step when upgrading to performance camshafts to unlock their full potential. Proper valve springs and retainers are also recommended to match the camshaft's specifications and prevent valve float at higher engine speeds.

When considering a camshaft upgrade like the GSC R15, it's essential to have a plan for tuning your engine management system. The increased airflow will require adjustments to fuel and ignition timing to optimize performance and ensure the engine runs smoothly and safely. This camshaft set is a popular choice for enthusiasts looking to extract more power from their RB26DETT engine, whether for spirited driving or competitive use. Please be aware that these camshafts are not CARB approved and cannot be shipped to California.
