The mountune m520 MRX upgrade replaces the OE turbocharger with a Borg Warner series larger frame unit to deliver incredible power output with minimal increase in turbocharger lag, greatly enhancing the driving experience.
Tested and validated over thousands of miles and countless hours on the dyno for durability and performance, the mountunem520 MRX turbocharger upgrade includes all required hardware, fittings and hoses needed for installation and is the perfect upgrade for customers already running either m400R or m400X.
Unlike other bolt on upgrades that deliver just peak or high RPM power, the m520 upgrade offers performance throughout the entire power band ensuring a very responsive and drivable car. The m520 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.
Engineered around the BorgWarner EFR turbocharger platform for seamless integration and excellent response and performance, the mountune m520 MRX upgrade has been developed as a complete system with everything available from one source, ensuring 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 whilst utilising the integrated recirculation valve ensures smooth drivability and throttle transition.
