mountune Fiesta ST MRX Turbocharger Upgrade

2364-TU-AA

Application
Fiesta ST 2014-2018

The Mountune MRX Turbocharger Upgrade for the 2014-18 Fiesta 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 along with engine calibration for a range of power levels and fuel types. This upgrade does not require any fuel system upgrades and is compatible with both 91, 93, and 94 octane fuel. The Fiesta MRX 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 offers performance throughout the entire power band ensuring a very responsive and drivable car. The Mountune 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 Fiesta ST MRX Turbocharger Upgrade is engineered around a genuine Garrett GT2554R core that features a custom engineered 11-blade billet compressor wheel and matching 3" inlet ant-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.

Love Love LOVE IT! August 1, 2017
Reviewer: Sergio Lopes from Hilmar, CA United States  
Install was mostly straight forward. There were no instructions but there working on them. The power curve is so much better. Before was all balls on the bottom end and fell flat on top. Now there's nothing special in first then it comes alive in second and doesn't stop. Had some torque limiting issues at first and some octane problems (my end) but randy has been patient with me (love u) lol. All and all the product and service has been great.

MRX and Randy July 1, 2017
Reviewer: Eddie  
The mrx trully is a great turbo. Pulls when I want it to and saves gas on the lower rpms. And there is still room to grow. (Currently 300hp 288tq  93oct not final revision)

Randy as a tuner is trully a genius. He takes his time to get everything diled in perfectly and takes no shortcuts.

This turbo and expecially the tune is definidently a steal.

Getting real May 15, 2017
Reviewer: GARY CARNES from Hermosa Beach, CA United States  
We ran into a few bumps along the way, but Mountune helped me get things tuned and dialed in. Excellent customer service and a great product. The car pulls so much differently than the stock car but in a good way. You still get that nice punch of torque, however now you can find it throughout. When the stock turbo would start to run out of breath around 5000 rpms , the MRX pulls all the way to 7000 rpms! Still running 91 octane and getting things dialed in but my 2 week impression is "yes it's worth it"
