mountune Focus RS MRX Turbocharger Upgrade

Application 2016-2018 Focus RS

The mountune MRX Turbocharger Upgrade is engineered around the BorgWarner EFR turbocharger platform for seamless integration and excellent response and performance. Developed as a complete system with everything available from one source ensures the performance and quality you’ve come to expect from mountune. Because of the unique Low Inertia Gamma-Ti Turbine Wheel, power comes on strong with amazing response and virtually no turbo lag. Integrated recirculation valve ensures smooth drivability and throttle transition. We rely on the BorgWarner EFR 7163 for the foundation of the MRX kit. The EFR 7163 lends itself well to incredible response with virtually no lag while producing incredible power and a very drivable car.



Power Increase
Power and performance levels can vary depending on supporting upgrades such as engine, fuel system and fuel type. Installations using the standard fuel system will have power levels similar to the graph above. Additional fuel system upgrades including upgraded high pressure fuel pump, auxiliary fuel system, E85 fuel including modified engine for strength can achieve up to 550hp. Power levels will always vary from installation to installation depending on installed upgrades, dyno type and weather.
