Performance Cams for Nissan RB25 NEO
The Kelford Cams range of camshafts for Nissan RB25 NEO engines have been designed to work with the stock variable VCT intake cam.
This allows our customers to retain lower rpm torque where a large fixed timing cam is not required.
This catalogue range of cams features our drop in street profiles with no head clearancing required.
High lift and custom cams that retain the NVCS/VCT are available upon request.
If you can't find your perfect camshaft within our catalogue, designing custom profiles is our specialty! Simply order the custom camshaft and provide us all the details of your build. Confidential development for race teams is also available.
Note:Neo cams are fitted with the Yoke style trigger only. By default we fit the Yoke type, if you need the "Spline & half Moon style" type please let us know when ordering.
