Overview

The GFB Mach 2 is a 100% recirculating diverter valve designed for quicker boost response and dependable boost holding.
Show original supplier description
The GFB Mach 2 is a 100% recirculating diverter valve that serves as a simple and essential modification for enhancing turbo performance. This Mach 2 valve is configured as a bypass, or plumb-back, unit, making it a direct factory replacement. The valve features a pressure-balanced design that allows it to hold unlimited boost, meaning it can withstand any pressure a turbo could produce without risk of damage. Unlike some factory bypass valves that are designed to open at a certain pressure to protect the engine, the Mach 2 is optimized for performance and throttle response. The Mach 2 is available in a range of universal and bolt-on kits for many popular turbo models. Simply remove the factory bypass valve and replace it with the Mach 2 for a straightforward upgrade. The T9102 Mach 2 TMS Recirculating Diverter Valve is specifically designed to fit a variety of turbocharged vehicles, including the Nissan Skyline R31 GTS-Turbo (RB20DET, 89-93), R32 GTS-t (RB20DET, 89-93), R33 GTS-t (RB25DET, 1993-1998), and R34 GT-T (RB25DET, 98-06). It also fits various Mazda models such as the 3 MPS BK (MZR L3-VDT, 06-09) and BL (MZR L3-VDT, 09-13), 6 MPS GG (MZR L3-VDT, 05-on), and CX7 (All 2.3 MZR L3-VDT, 06-on). Additionally, it is compatible with Mitsubishi Eclipse 1G (4G63t, 1990-1994) and Galant VR4 (E38A-E39A 4G63, 90-93).
