GSC Power Division Billet S2 Exhaust Camshaft Nissan RB26DETT R32/R33 Skyline GT-R 1989-2002 | 7041S2EX

GSC builds this S2 exhaust camshaft specifically around the RB26DETT — not a generic profile adapted to fit, but developed considering the RB26's cylinder head flow, valvetrain geometry, rocker motion, and typical boost and fuel setups. That application-specific approach is what separates a real performance cam from a catalog part that happens to bolt in.

The cam is machined from forged billet barstock in-house, with a precision-ground lobe profile built for real-world power delivery and valvetrain stability at the RPM this engine is actually going to see. The S2 exhaust spec steps up duration and lift over stock, aimed at pulling more flow out of the cylinder on the exhaust stroke without giving up low-RPM manners.

Fitment: Nissan RB26DETT.
Note: Camshaft changes often require upgraded valve springs to maintain valve control at higher RPM and boost — confirm spring compatibility before ordering. ECU recalibration is also recommended after install to get the most out of the new profile and keep the engine running safely. This is the exhaust-side cam only — the intake cam is sold separately.
