GFB Hybrid Dual Port Blow Off Valve Nissan Silvia/180SX (S13) / 300ZX (Z32) / Pulsar GTiR (N14) 35mm/30mm

GFB Hybrid Dual Port Blow Off Valve - Nissan Silvia/180SX (S13) / 300ZX (Z32) / Pulsar GTiR (N14) - 35mm/30mm

GFB built its reputation on the original Hybrid, the world's first dual port blow off valve, and this updated version brings the same staged venting design back into production. Perfect for the Nissan Silvia, 180SX, 300ZX and Pulsar GTiR, it lets you dial in full recirculation, full atmosphere venting, or a 50/50 blend to suit your MAF setup and how loud you want it.

This listing covers the Nissan Silvia S13 and 180SX S13 (SR20DET), the Nissan 300ZX Z32 (VG30DETT), and the Nissan Pulsar GTiR N14 (SR20DET), fitted with the 35mm/30mm dual port valve body. SKU T9235.

Note: 300ZX Z32 applications require two valves per car. Pulsar GTiR N14 owners need the softer spring (part 6116) fitted for the valve to open correctly, or alternatively the vacuum hose can be teed into all four individual throttle bodies instead of a single point.
