Kelford Cams RB25DET NVCS R33 Camshafts
The RB25 VCT/NVCS engine was brought out in Nissan’s R33 Skyline AKA the “BOAT”. The range listed is designed for hydraulic lifter engines, however solid profiles are available on request. The low lift lobe designs on the A and A2 cams have proved very popular because there is no requirement for head clearancing.
IMPORTANT NOTE – Nissan RB camshafts have a drive fitted to the front of the exhaust camshaft. All Kelford camshafts are fitted with RB drive type 1 as pictured (see images). If you have a later model engine with drive type 2, please let us know this when you place your order and we will fit that type instead. Lead times may apply.
If you can’t find your perfect camshaft within the Kelford Cams Camshaft options, please contact us to discuss your requirements and the endless range of custom camshafts.
