The 2014-2019 Fiesta ST is one of the best bang-for-your buck performance hatches available today. With a nimble, well-balanced chassis and potent 1.6T EcoBoost engine, this little Ford already punches above its weight. But there’s so much more potential waiting to be harnessed.

 Having identified the size of the stock turbine housing and internal wastegate as the main restrictions, we set about developing a big-turbo set-up from scratch. Although hybrid units are available for the 1.6T EcoBoost, we firmly believe that a big turbo is the better performance option. It was essential that the package delivered more power, but without the high boost levels and associated stress of a hard-worked hybrid. As with any PERON product, the watchwords were Performance, Drivability and Durability.


Developed by our in-house technical partners, Nortech Performance and beautifully crafted from T304 stainless steel, this robotically TIG-welded component features a CNC-machined billet merge collector, along with optimised primary dimensions and CNC Nortech signature head flange. Not only does this bespoke manifold optimise exhaust gas flow, it also looks like a work of art.


Included with the package is a PERON high-flow de-cat downpipe. Manufactured from T304 stainless steel, including flanges, flexible section and lambda bosses, this robotic TIG-welded component has been specifically designed for use with the Garrett turbocharger. Please note: this item is designed for off-road use only. We are currently working on a sports cat downpipe solution that will be available in March.

A little difficult for DIY guys but man this kit truly is perfect for the car couldn’t ask for any better quality. Spool is awesome and man the power is there.

True work of art

Everything in this kit is beautiful. Almost a shame to hide it in the engine bay! The manifold is amazing. The turbo means business. I have had this kit installed for a few months now and it absolutely rips, especially over 4000rpms. It has made 394whp and 358wtq and has been 11.73 @ 119.9mph in the 1/4 mile. It will spin the tires at 60mph! It works great on a stock engine but will truly be a force with a better engine. Can't wait to turn the boost up and let it fly!
