Application 2016-2018 Focus RS
The mountune MRX Turbocharger Upgrade for the 2016-2018 Focus RS offers incredible power output with minimal increase in turbocharger lag, which greatly enhances the driving experience.
Tested and validated over thousands of miles and countless hours on the dyno for durability and performance, the mountune MRX Turbocharger Upgrade includes all required hardware, fittings and hoses needed for a complete installation. This upgrade does not require any fuel system upgrades and is compatible with both 91, 93, and 94 octane fuel. However vehicle fuel system upgrades along with internal engine upgrades will allow you to reach the maximum potential of this kit at over 550hp.
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 bolt on 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 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 IncreasePower 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.

mountune MRX Turbocharger Upgrade Q &A
1. Does the stock clutch handle the power?
The turbo upgrade was tested on a car with the standard clutch and there were no signs of
slipping during the 10,000 mile test cycle. Driving style and use would also have an effect on
the clutch life and performance.
2. Will the stock transmission be OK with the turbo kit?
The turbo upgrade was tested on a car with the standard transmission and there were no
signs of any issues during the 10,000 mile test cycle. Driving style and use would also have
an effect on the life of the transmission.
3. Can I use my original or other aftermarket intake?
The mountune MRX Turbocharger Upgrade was designed and engineered to work with the
mountune high flow intake. However other intake options may be compatible with some slight
modifications to the intake hose assembly or the intake itself.
4. Does the mountune MRX Turbocharger Upgrade have a C.A.R.B. EO?
The mountune MRX Turbocharger upgrade does not have a C.A.R.B. EO and therefore is for
motorsport use only.
5. I already have a BorgWarner EFR Turbocharger. Can I just buy the base components?
The BorgWarner EFR Turbocharger included in the mountune MRX Turbocharger upgrade
has been configured by our engineers with the correct fittings along with unique wastegate
mounting solution. Additionally, we have pre-adjusted the wastegate tension to ensure
reliable performance within the parameters we have tested. To ensure the upgrade's
performance we do not offer the kit without the turbocharger.
6. Are there options for larger or different turbochargers?
The mountune MRX Turbocharger upgrade has been configured to offer well balanced
drivability for a front wheel drive platform coupled with extreme performance using the BorgWarner EFR 7163 turbocharger.
7. Can I use my existing downpipe or another manufactures downpipe?
The size and exit angle of the exhaust flange on the larger turbocharger requires a downpipe
to meet the specific requirements of the BorgWarner EFR 7163 series Turbocharger. The
mountune downpipe for the MRX upgrade has been engineered to fit within the space
constraints while offering maximum flow and secure installation. Therefore it is advisable to
use the mountune downpipe option.
8. Is custom tuning available?
Not from Mountune but we can refer you to a competent tuner.
9. Will this turbo kit void my warranty?
Due to the nature of motorsport and racing product usage the Mountune MRX turbo upgrade is not covered by the original factory Ford warranty.
