The mountune m285/m310 power upgrade utilises our extensively proven MRX Turbocharger Upgrade and offers Mk7 Fiesta ST owners greater power output with minimal increase in turbocharger lag, which greatly enhances the driving experience.

The m285 MRX turbocharger upgrade includes all required hardware, fittings and hoses along with our performance engine calibration and has been developed as a more than worthy successor to the much heralded MR265 upgrade and also provides a higher-output option for owners that have yet to upgrade their turbo.

Unlike other upgrades that deliver just peak or high RPM power, the m310 MRX Turbocharger offers performance throughout the entire power band ensuring a very responsive and drivable car. 

The MRX Turbocharger at the heart of the m310 upgrade is engineered around a genuine Garrett GT2554R core that features a custom engineered 11-blade billet compressor wheel and matching 3" inlet anti-surge compressor housing for incredible response and power. Developed as a complete system with everything available from one source ensures the performance and quality you’ve come to expect from mountune.
