Building on the hugely popular Fiesta ST MR230 upgrade kit - which maximised the reliable and safe performance output of the 1.6-litre EcoBoost whilst retaining the standard turbocharger, the MR265 turns things up a few clicks on the performance dial! The MR265 builds upon the hardware found in the MR230 upgrade and in addition adds; a new hybrid turbocharger, high-flow rear intake pipework, silicone hoses and a larger intercooler, all fully optimised by the MR265 calibration, which is installed via our mTune handset.
Maintaining the modular approach where possible, all previously released kit hardware is retained, with the exception of the intercooler. At these higher power and torque outputs, particularly under sustained use, our original intercooler could not match the performance of our full-height variant. Whilst peak power and torque figures may not be achieved - certainly in warmer climates and / or under sustained use, the MR265 upgrade will still be available to MP/MT215 and MR230 owners that have already purchased our original intercooler, at a reduced cost - check out the matrix below for the various MR265 pricing options.
So how does MR265 stack up against our Ford-endorsed MP215 upgrade and our smile-inducing MR230? Well, it packs an additional 50Nm of torque over MP215 and 30Nm above MR230, whilst power is 50PS up when compared to MP215 and 35PS over MR230. There's no doubting that the additional performance is hugely impressive; maintaining and combining impressive turbo response and silky-smooth drivability, with a relentless wall of torque that's mated in harmony with a top end that just wants to just keep revving!

N.B. Prices do not include installation.
At the heart of the MR265 upgrade is the hybrid turbocharger which has been developed by the mountune engineering team and is produced for us by the team at Owen Developments.
The standard unit was at its maximum safe operating limit around 230PS so the turbo has been substantially re-worked to provide the uprated, reliable boost (see what we did there?) in performance required for MR265. Incorporated in the costs of all of the upgrade versions is also a new oil feed, required gaskets, studs and nuts, meaning the only thing the end-user requires is an oil and filter change - this must be performed after the new turbo has been installed and before the engine is run.
Once the final components arrive with us in stock, MR265 will be made immediately available (excluding the USA), so stay tuned to our social channels to be the first to know when you can take the next step in realising your Fiesta ST's full potential!
The rear high-flow intake pipework and our larger intercooler will also be made available to purchase separately.
