Description
The mountune MRX Turbocharger Upgrade for the 2013-18 Focus ST offers greater power output with minimal increase in turbocharger lag, which greatly enhances the driving experience.
Tested and validated over thousands of miles for durability and performance, the mountune MRX Turbocharger Upgrade includes all required hardware, fittings and hoses. This upgrade does not require any fuel system upgrades and is compatible with both 91, 93, and 94 octane fuel. The mountune MRX Focus Turbocharger Upgrade has been developed for those that desire a fully engineered upgrade that provides an optimized power band. Unlike other upgrades that deliver just peak or high RPM power, the mountune MRX Turbocharger Upgrade offers performance throughout the entire power band ensuring a very responsive and drivable car. The MRX Turbocharger Upgrade is designed for those that are looking for well balanced yet extremely powerful performance derived from years of developing race winning Ford 4 cylinder turbocharged engines.
The standard BorgWarner K03 based turbocharger, as found on the Ford EcoBoost engine in the Focus ST, is a capable turbocharger with excellent response and power potential up to the low 300bhp range. For power outputs above that level, a larger turbocharger is required.
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 6258A for the foundation of the MRX kit. The EFR 6258A lends itself well to incredible response with virtually no lag while producing incredible power and a very drivable car. For those that wish to go further with slightly higher power levels, the MRX kit is available with the BorgWarner EFR 6758 or EFR 7163 Turbocharger, additional cost may apply.
