The RA301A-NS05G is a high-performance camshaft set designed specifically for the Nissan Skyline GT-R models BNR32 and BCNR33, equipped with the RB26DETT engine. This camshaft set is tailored to enhance the engine's overall performance by optimizing the valve timing, allowing for greater airflow, higher RPM capabilities, and more aggressive tuning.

Key Features:

• Camshaft Specifications:

  • Duration: 282° (Intake and Exhaust)
  • Valve Lift: 10.80mm (solid at cam), 10.42mm (intake valve), 10.35mm (exhaust valve)
  • Lobe Center: 110° (Intake), 115° (Exhaust)

• Compatibility:

  • Designed for Nissan Skyline GT-R BNR32/BCNR33 models with the RB26DETT engine.

• Performance Benefits:

  • Increases the engine’s ability to intake air and exhaust gases efficiently, contributing to an overall increase in horsepower and torque, especially at higher RPMs.

• Load Specifications:

  • Set Load: 24.0 kgf ±7%
  • Lift Load: 77.2 kgf ±7%

• Dimensions:

  • Normal Height: 44.0mm
  • Set Length (In): 37.7mm
  • Exhaust Lift Length: 27.2mm
  • Compressed Height: 26.1mm

• Cam Timing:

  • Intake (BTDC): 32.0°
  • Exhaust (ABDC): 70.0°
  • This results in improved engine performance, particularly in high-performance setups or tuning where airflow optimization is essential.

• Additional Considerations:

  • The camshaft set requires specific valve springs to handle the increased load and high-performance nature of the cam profile.
  • The set should be installed with caution, ensuring that valve clearance is thoroughly checked before installation, as variations in the cylinder head manufacturing may lead to cam lobe interference.
