The HKS Camshaft 2202-RN126 is a high-performance intake camshaft designed for the Nissan RB26DETT engine, commonly found in the Nissan Skyline GT-R models (R32, R33, and R34). This camshaft aims to enhance engine performance by optimizing valve timing and lift characteristics, contributing to increased power and efficiency.​

Key Features:

• Camshaft Specifications:

  • Duration: 272 degrees​
  • Maximum Valve Lift: 8.7 mm​
  • Valve Timing (using stock cam sprocket):
    • Open (BTDC): 30 degrees
    • Close (ABDC): 90 degrees
    • Top (ATDC): 120 degrees
    • Total Duration: 300 degrees

• Performance Enhancement:

  • Optimized Airflow: The 272° duration and 8.7 mm valve lift are designed to enhance airflow into the engine, improving combustion efficiency and increasing power output, especially at higher RPM ranges.​
  • High-RPM Performance: Designed to support engine speeds up to approximately 8,000 RPM, this camshaft is suitable for high-performance applications requiring robust valve timing.
• Compatibility:
  • Vehicle Fitment: Compatible with Nissan Skyline GT-R models equipped with the RB26DETT engine.
  • Valve Train Components: This camshaft is designed for use with factory valve springs. However, due to its high-performance profile, the use of HKS high-performance valve springs is recommended to ensure optimal performance and reliability.

• Installation Considerations:

  • Direct Replacement: Designed as a direct replacement for the stock camshaft, facilitating straightforward installation without the need for extensive modifications.​
  • Supporting Modifications: For optimal performance, especially at higher RPMs, pairing this camshaft with supporting modifications such as upgraded valve springs, retainers, and ECU tuning is advisable.​

Benefits:

• Enhanced Power Output: Improved valve timing and lift characteristics contribute to increased engine power, particularly beneficial for high-performance and racing applications.​
• Improved Throttle Response: Optimized valve events lead to better throttle response and acceleration.​
• High-RPM Capability: Designed to support higher engine speeds, making it suitable for performance enthusiasts seeking enhanced high-RPM capabilities.

USAGE CONDITIONS:

•  This camshaft must be used with the factory valve springs. 
• Maximum Capable Engine RPM (less than the stock rev. limiter) : Approximately 8,000rpm 
•  Tappet Clearance 
  • Cold State (20±5℃): 0.45±0.02mm 
  • Warm State (Reference):  0.51±0.02mm
