The Kelford Cams RB25DET Camshaft range offers three camshaft profile options each offering a unique throttle response, power improvements and level of modification. This range is to suit the RB25DET VCT/NVCS (non-neo, hydraulic) engines released in the turbo Nissan Skyline R33.
IMPORTANT NOTE – Nissan RB camshafts have a drive fitted to the front of the exhaust camshaft. All Kelford RB camshafts are fitted with the spline and half moon type. If you have a later model engine with the yoke shaped type, please let us know this when you place your order and we will fit that type instead. Lead times may apply.
