The HKS RB26 V-CAM System Step 1 is an intake cam upgrade designed for the Nissan Skyline GT-R (89-02). This system modifies the intake cam side of the RB26DETT engine to incorporate variable valve timing, enhancing overall performance. With a cam duration of 248 degrees, it offers a balanced approach that improves power delivery across a broad RPM range. The variable timing feature allows for increased low-end torque and high-RPM power, making it suitable for both street and circuit use. Constructed with precision engineering, this cam system aims to optimize airflow and combustion efficiency, resulting in better acceleration and overtaking capabilities without sacrificing reliability.

Designed specifically for 1989 to 2002 Nissan Skyline GT-R models, this V-CAM system is a direct upgrade for the intake side of the RB26DETT engine. It is ideal for enthusiasts seeking improved throttle response and increased power at various RPM levels. The system does not include a Valcon controller, allowing for customizable tuning based on individual preferences or existing setups. Installation is a bolt-on process for experienced technicians familiar with the RB26 engine. This kit provides a performance-focused enhancement suitable for street driving, track days, or competitive racing, delivering noticeable gains in power and drivability.

Overview

The intake cam side of the RB26DETT is changed to allow variable valve timing. The cam has duration of 248 degrees which seem a little conservative. However, with the variable timing, power increases can be found at low or high RPM.Whether you are looking to find some time on the circuit through improve acceleration out of lower speed corners, or simply want something which can overtake with ease on the street, the HKS V Cam System provides good power from low RPM reducing the necessity for excessive gear changes. This especially noticeable when going from vacuum to boost to give the feeling of increased displacement.Improved valve timing will allow for more complete combustion leading to improved fuel efficiency and cleaner exhaust emissions. HKS V CAM System is compatible with the stock pistons. When using with the thinner head gaskets or modified cylinder head, the clearance between valve and piston may be insufficient.Exhaust cam should be selected dependent on turbo choice. Recommended: GT-SS-256 degrees, GT2530-264 degrees

NOTE: Compatible the stock piston. Surface polishing on the cylinder or using a thin gasket may cause insufficient clearance between the valve and the piston.

  • Do not use this product if the bottom of the cylinder head or the upper side of the engine block has already been modified so an adequate valve recess cannot be maintained.
  • Additional oil piping is required in order to install this kit.
  • This kit does not include the camshaft for the exhaust side.
  • It’s recommended to upgrade the factory oil pump to the large capacity type.
  • Sparate purchase of the F-CON V Pro3.4 or Valcon type RB control device is needed.
