The HKS Camshaft 2202-RN130 is a high-performance intake camshaft designed for the Nissan RB26DETT engine, specifically optimized for motorsports and high-performance driving. It is a part of the HKS Step 2 camshaft series and is designed to provide significant improvements in engine power, especially in high RPM ranges.

Key Features:

• Camshaft Specifications:

  • Duration: 272°
  • Maximum Valve Lift: 10.2 mm
  • Valve Timing (using stock cam sprocket):
    • Open (BTDC): 30°
    • Close (ABDC): 90°
    • Lobe Center (ATDC): 120°
    • Total Cam Duration: 300° (at 0mm valve lift)
    • 1mm Valve Lift Duration: 236°

• Maximum RPM Range: 9500 RPM (depending on engine setup)

• Performance Enhancement:

  • Increased Airflow: The higher duration and valve lift improve airflow into the engine, enhancing combustion efficiency and power output.
  • Engine Efficiency: It is designed to optimize valve events, enabling quicker throttle response and higher power output, particularly at high RPMs.
  • Sports and Racing Use: Specifically designed for closed-circuit racing and high-performance applications, this camshaft is optimized for use in motorsport environments.

• Compatibility:

  • Engine Model: Nissan RB26DETT (used in R32, R33, and R34 Nissan Skyline GT-R models).
  • Valve Springs: Best paired with HKS Step 2 strengthened valve springs (HKS Part No. 22001-AN001) to handle the increased demands of high lift and RPM.

• Installation Considerations:

  • Valve Clearance Adjustment: Since the base circle diameter of the camshaft is smaller than stock, valve clearance adjustment is necessary.
  • Cylinder Head Modification: The cylinder head must be modified to ensure a 0.5-1.0mm clearance between the camshaft lobes and the cylinder head.
  • Tuning Required: Fine-tuning of the valve timing with either the stock or adjustable cam sprockets is recommended for optimal engine performance.

• Performance Benefits:

  • Increased Horsepower and Torque: The camshaft provides noticeable improvements in power, especially at higher RPM ranges, making it ideal for motorsport and high-performance applications.
  • Enhanced Throttle Response: Optimized valve timing leads to faster engine response, improving overall vehicle performance on the track.

• Durability and Reliability:

  • Manufactured by HKS, this camshaft is built from high-quality materials, ensuring long-lasting performance even in demanding motorsport environments.

Supporting Modifications and Requirements:

• Valve Springs: HKS Step 2 strengthened valve springs are required to safely handle the increased lift and high RPM range.
• Cylinder Head Modifications: Modifications are necessary to provide clearance for the camshaft lobes, ensuring smooth operation and avoiding damage to the engine components.
