Hybrid Dual Outlet Diverter / Blow-Off Valve for Nissan SR20DET Applications

GFB’s Hybrid Dual Outlet design was created to deliver blow-off sound without the drivability issues that can come with full atmosphere venting on many turbo setups. The T9204 uses staged dual-port venting so the recirculation outlet opens first, with the atmosphere outlet coming in as boost demand increases.

Configurable Venting Options

• Full recirculation for quiet, factory-style operation
• 50/50 venting for a balance of sound and drivability
• Full atmosphere venting for maximum blow-off sound

Staged Dual-Port Operation

By prioritising recirculation before venting to atmosphere, the Hybrid design helps maintain smoother airflow and more consistent behaviour during light throttle changes, while still delivering a strong blow-off sound when driven harder.

Built for Real-World Turbo Use

Designed as a straightforward upgrade path for compatible Nissan applications, the T9204 delivers flexible venting control in a compact, serviceable valve format.
