  Genuine OEM JDM Nissan SR20DET Variable Timing Control (VTC) Solenoid Valve Assembly — Part # 23796-1N51A

  One of the most highly sought-after genuine OEM engine components in the SR20 community — the factory VTC solenoid valve for the SR20DET Black Top engine. This is the genuine Nissan solenoid that controls oil pressure to the VTC (Variable Timing Control) cam gear, advancing and retarding intake camshaft timing for optimal power delivery across the RPM range. Sourced from authorized Nissan dealer stock — not a reproduction, not a copy.

  ⚠️ Engine Variant Note — Black Top SR20DET Only: This VTC solenoid is specific to the Black Top SR20DET (S14 and S15). The Red Top SR20DET (S13) uses a different VTC solenoid. Always confirm your engine variant before ordering. This part is also recommended for replacement during camshaft upgrades or engine rebuilds.

  Why buy genuine? Aftermarket VTC solenoids for the SR20DET are widely available but consistently criticized in the SR20 community — incorrect oil flow rates, wrong solenoid resistance, and materials that degrade quickly under sustained boost. The genuine Nissan solenoid is the only unit calibrated to the SR20DET's exact oil pressure and timing advance specifications. For a road car, a track build, or a full engine rebuild, the genuine part is always the correct choice.

  When you need this part:

  • VTC solenoid failed — no camshaft advance at high RPM
  • Ticking or rattling from the VTC gear area at idle or light throttle
  • Engine rebuild — always replace the VTC solenoid with new
  • Camshaft upgrade — replace solenoid to ensure proper oil control with new cams
  • Timing-related fault codes or rough power delivery across the RPM range
