The HKS Step 1 Camshaft 2202-RN124 is a high-performance camshaft specifically designed for the Nissan RB26DETT engine, commonly found in Nissan Skyline GT-R models (R32, R33, and R34). This camshaft enhances engine performance by optimizing intake valve timing and lift characteristics, contributing to increased power and efficiency. It is ideal for enthusiasts looking to boost engine output without extensive modifications to the valve timing system.

Key Features:

• Camshaft Specifications:

  • Duration: 264 degrees
  • Maximum Valve Lift: 8.7 mm
  • Valve Timing (using stock cam sprocket):
    • Open (BTDC): 26 degrees
    • Close (ABDC): 86 degrees
    • Top (ATDC): 110 degrees
    • Total Duration: 292 degrees
  • Intended Position: Intake
  • Base Radius: 32 mm

• Performance Enhancement:

  • Optimized Airflow: The camshaft’s 264° duration and 8.7mm valve lift are designed to improve airflow, allowing for more efficient combustion and increased power.
  • Increased Power and Torque: The higher profile camshaft is intended to enhance engine output, especially at higher RPM ranges, while maintaining good drivability for street use.

• Compatibility:

  • Specifically tailored for the Nissan RB26DETT engine, ensuring perfect fitment with the factory valve train components.
  • Compatible with stock or lightly modified cylinder heads, making it an easy bolt-on upgrade for tuning enthusiasts.

• CAD-Designed for Performance: HKS camshafts are designed using advanced CAD (Computer-Aided Design) technology to optimize torque and horsepower across the broadest possible power band, ensuring the best performance gains.

Material and Construction:

• Billet Core Construction: HKS camshafts are machined from new billet cores made of high nickel content iron alloy, which ensures a strong and durable camshaft capable of withstanding high-performance applications. This billet construction provides superior quality compared to OEM camshafts.
