If you’re looking to upgrade your Nissan 200SX S14 or S15 (1995-1998), the Go Fast Bits Mach 2 Bypass Valve is a must-have component for enhancing your turbo setup. This valve is designed specifically for turbocharged applications, offering a seamless bolt-on installation that requires no additional adapters or modifications to your vehicle. Just swap out your factory bypass valve, and you’re good to go!
The Mach 2 is engineered as a 100% recirculating valve, meaning it efficiently redirects boost back into the intake system without the loud venting noise. This is perfect for those who want to maintain a stealthy performance profile while still getting the most out of their setup. However, if you’re in the mood for some auditory excitement, you can easily convert it to a 100% atmospheric venting setup with an additional kit.
Factory bypass valves typically have two key limitations: they don’t open until a certain pressure is reached, which can hinder throttle response, and they can stall your engine if vented to atmosphere. The Mach 2 addresses these issues head-on. It can handle unlimited boost pressure—no turbo will ever produce enough to damage it—while the TMS technology ensures lightning-fast throttle response. Plus, with the atmospheric conversion kit, you can vent without the worry of engine stalling.
One Nissan 240SX S14 owner shared, “I installed the Mach 2 and immediately noticed a difference in throttle response. The installation was a breeze—just a simple swap. I went with the recirculating setup initially, and it’s super quiet. I’m thinking about adding the atmospheric conversion kit next for those track days!”
Upgrade your Nissan 200SX or 240SX with the Go Fast Bits Mach 2 Bypass Valve and experience the performance benefits that come from a well-designed, reliable component. Whether you’re hitting the streets or the track, this valve is a solid addition to your turbocharged setup.
