Show original supplier description
The MODE Auto Concepts Mach 2 TMS is a 100% recirculating diverter valve engineered for enhanced boost response and improved throttle control. Its pressure-balanced design ensures it can effectively hold unlimited boost, meaning no turbo could produce enough pressure to damage it. This Mach 2 diverter valve is configured as a fully recirculating (bypass, plumb-back) unit, serving as a direct replacement for your stock bypass valve. It's ideal for enthusiasts seeking performance gains without the audible blow-off valve sound, maintaining a 'sleeper' profile. Unlike many factory bypass valves that are designed to open above a certain pressure to protect the engine, the Mach 2 is optimized for both boost holding capability and throttle response. The valve features a 35mm inlet and a 30mm outlet. It is constructed from aluminum and weighs 0.56 kg, with dimensions of 5.4 x 19.5 cm. The Mach 2 is designed as a direct bolt-on, requiring no additional adapters, parts, or vehicle modifications for installation. Simply remove the factory bypass valve and install the Mach 2 in its place. This specific model, T9135, is designed to fit the MY97-98 Subaru WRX/STi. It also suits various Nissan models including the GTi-R N14 SR20DET (1990-1995), 300ZX Z32 VG30DETT (89-97), 180SX S13 2.0 SR20DET, and Silvia S13 2.0 SR20DET (88-94).
