GFB T9300 SXV Mini Recirculating Bypass Diverter Valve

The GFB T9300 SXV Mini is a high-performance recirculating bypass valve (diverter valve) engineered to replace weak, failure-prone OEM plastic bypass valves on turbocharged vehicles. Built by Go Fast Bits — a proudly Australian manufacturer operating under ISO 9001 quality standards — the SXV Mini delivers superior reliability, boost retention, and throttle response in a compact form factor.

Unlike a standard OEM bypass/diverter valve, which remains open until it needs to close (increasing turbo lag), the SXV operates on a closed-until-needed principle. By only venting boost pressure when necessary, the SXV eliminates the lag penalty imposed by the factory valve and delivers the sharpest throttle response your turbo system is capable of producing.

Why Replace Your OEM Diverter Valve?

Factory plastic bypass valves are notorious for cracked housings and diaphragm failures that result in significant boost loss and degraded performance. A leaking OEM valve can also cause turbo overspeeding, accelerating wear or even causing turbo damage. The T9300 SXV Mini uses uncompromising materials and construction to ensure all boost reaches the engine efficiently.

Key Features:

• CNC-machined billet aluminium and brass construction for long-lasting durability
• Anodised finish for corrosion resistance and clean aesthetics
• 25mm inlet and outlet connections for straightforward hose integration
• 5mm vacuum hose nipple, rotatable to 4 positions for flexible installation
• 100% recirculating (plumb-back) design — maintains factory ECU compatibility and emissions compliance
• Adjustable spring pre-load to match your vehicle's idle vacuum signal
• Holds unlimited boost pressure — no rebuild kits ever needed
• Backed by GFB's lifetime warranty

The T9300 SXV Mini is ideal for integrating a diverter valve into a turbo system that didn't previously have one, or as a compact OEM replacement. Whether you're running a stock tune or a modified build, the SXV Mini is engineered to keep up.
