GFB Deceptor Pro II Electronic Blow Off Valve - Nissan Silvia/180SX (S13) 300ZX (Z32) Pulsar GTiR (N14) - 35mm/30mm
GFB has taken the guesswork out of blow off valve tuning with the Deceptor Pro II, a genuine step up for anyone running a Nissan Silvia, 180SX, 300ZX or Pulsar GTiR. Instead of committing to one fixed venting bias, you get an in-cabin controller that lets you dial the sound and response from near silent through to full atmospheric blow off, all on the fly.
This listing covers the Nissan Silvia S13 and 180SX S13 (SR20DET), 300ZX Z32 (VG30DETT) and Pulsar GTiR N14 (SR20DET), with the valve featuring a 35mm/30mm porting configuration designed to bolt into most factory locations.
Important: the 300ZX Z32 twin turbo requires two valves per vehicle. The Pulsar GTiR N14 requires the softer spring (part #6116) fitted, or alternatively the vacuum hose teed into all four individual throttle bodies, otherwise the valve will not open correctly.
Key Features
- Electronic, remote proportional venting bias and volume control
- Backlit in-car controller dial
- Adjustable end point to set maximum atmospheric vent bias
- High-torque geared electric motor with sealed ball-bearing gear train
- Revised porting for improved flow
- Compact design suits most factory valve locations
- Supplied with all wiring and hardware required for installation
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please ensure your vehicle's year, chassis, and engine configuration are confirmed before ordering.
