HKS Nissan S13 SR20DET 256 Intake Camshaft 1989-1994

The HKS 256 Intake Camshaft upgrades the Nissan S13 SR20DET engine in 1989-1994 Silvia and 180SX models. This high-angle cam delivers increased valve duration for better mid-to-high RPM power and throttle response. Pair it with matching valve springs for full potential in tuned builds.

Key Features

  • 256 Degree Duration: Extends intake valve timing to pull in more air at high RPM for stronger top-end power gains
  • 11.15mm Lift: Raises intake valves higher to improve airflow volume without excessive stress on valvetrain
  • High-Strength Steel Construction: Heat-treated and precision-ground for durability under boost and high revs
  • Direct Bolt-On Fit: Matches factory journal sizes for seamless installation on SR20DET Blacktop engines
  • Optimized Profile: Balances power delivery with drivability for street and track use

Product Notes

  • Valve spring upgrade recommended for revs over 8500 RPM to prevent coil bind
  • Verify piston-to-valve clearance before full assembly
  • Store in dry conditions to maintain surface finish

Installation Notes

  • Professional installation recommended.
  • Set intake valve lash to 0.22-0.28mm cold after install
  • Requires cam timing adjustment using HKS specs or degree wheel
