What is the difference between recirculation and atmospheric venting?

Recirculation vents boost pressure back into the intake system before the turbo, which is generally quieter and safer for airflow sensors. Atmospheric venting releases the pressure to the outside air, creating the audible 'pssh' sound often associated with performance turbochargers.

How do I change the venting configuration?

The valve comes with a set of blanking plugs. By strategically placing these plugs, you can switch the valve's operation between full recirculation, a 50/50 split, or full atmosphere venting to suit your preference.

Is this valve compatible with my stock turbo?

The GFB Hybrid TMS Dual Port valve is designed as a direct fit replacement for the factory blow-off valve on the specified Mazda and Nissan models. It is intended to work with the stock turbocharger system.

Product Details

This is the Go Fast Bits Hybrid TMS Dual Port valve, a direct-fit bolt-on replacement for your Mazda 3 (2007-2013), Mazda 6 MPS (2006-2007), CX-7 (2007-2012), or compatible Nissan Skylines. It's a diverter valve designed to manage boost pressure in turbocharged engines. The Hybrid valve is unique because it combines two venting outlets: one recirculates air back into the intake system, and the other releases it to the atmosphere. This setup is particularly useful for vehicles with sensitive airflow meters, as it helps prevent issues like backfiring or stalling while still allowing you to hear the characteristic blow-off sound.

What you get in the box are the valve itself and a set of blanking plugs. These plugs let you easily switch the valve's operation between full recirculation, a 50/50 split between recirculation and atmosphere, or full atmosphere venting. This adjustability means you can tailor the sound and performance to your preference. The TMS technology is also notable, as it's designed to help recover boost pressure up to 30% faster during gear shifts, potentially improving throttle response.
