The HKS Camshaft 2202-RN128 is part of HKS’s performance camshaft series specifically designed for the Nissan RB26DETT engine found in the Nissan Skyline GT-R (R32, R33, R34). This camshaft is part of the HKS Step 2 series, intended for high-performance and racing applications.

Product Features:

• Camshaft Specifications:
  • Duration: 264°
  • Maximum Valve Lift: 10.0 mm
  • Recommended Valve Springs: HKS Step 2 Reinforced Valve Springs (Part No. 22001-AN001)
  • RPM Range: Max RPM around 9,200 for optimal performance (may vary based on other modifications)
• Performance Features:
  • The camshaft’s design enhances the intake air flow, increasing engine performance by optimizing valve timing for greater power output.
  • It is designed for high-revving engines and is suitable for use in closed-circuit (track) motorsports, offering significant performance increases during racing scenarios.
  • The camshaft has been developed with increased valve lift and timing compared to the stock camshaft, resulting in better intake and exhaust flow, crucial for performance enhancements.
• Installation Requirements:
  • Cylinder Head Modifications: The cylinder head must be modified to ensure a 0.5–1.0mm clearance between the camshaft and the cylinder head.
  • Valve Clearance Adjustment: Requires adjustment due to the smaller cam base circle compared to stock parts. This ensures proper valve clearance and avoids interference between the valve and piston.
  • Usage of HKS Reinforced Valve Springs: To handle the increased lift and duration effectively, HKS Step 2 reinforced valve springs are required.
• Maximum Valve Lift and Timing Details:
  • Open Timing (BTDC): 26°
  • Close Timing (ABDC): 86°
  • Lobe Center (ATDC): 120°
  • Total Duration (0mm Lift): 292°
  • Total Duration (1mm Lift): 228°
• Engine Compatibility:
  • Designed specifically for the Nissan RB26DETT engine, including models from the Skyline GT-R R32, R33, and R34.

Additional Information:

• Valve Timing Settings: The camshaft provides the best performance when used with factory cam gears, although adjusting the valve timing can lead to even more noticeable performance gains, especially in motorsport settings.
• Important Considerations: Due to the high lift and duration, this camshaft is not recommended for everyday street use unless supporting modifications (such as reinforced valve springs and ECU tuning) are applied. Engine conditions and modifications can affect the final performance gains.

Usage Notes:

• Performance Usage: The camshaft is primarily designed for closed-circuit racing, such as sports driving or competitive motorsport events.
• Regular Maintenance: Proper maintenance, such as regular oil changes and monitoring of temperature and oil pressure, is crucial to maintaining the engine's performance when using this camshaft.

The 2202-RN128 is engineered to provide noticeable improvements in high-RPM performance, throttle response, and overall engine output, making it a suitable choice for motorsport enthusiasts or those looking to push their RB26DETT engine to higher performance levels.
