To build the perfect turbocharger you must understand the desires of the customer and understand the dynamics of the engine itself.
The 1.6 EcoBoost motor has no better home than Pumaspeed, with 20+ years experience, race engines being built every week to power levels of over 450bhp you couldn't be in better hands.

The X57 series of turbochargers have been designed from the ground up with a no compromise attitude. They feature the very latest spec genuine K04 / K16 Motorsport internals and state of the art billet 7 blade CNC compressor wheels. The exhaust housing has even been manufactured from one of the most advanced materials, D5B Niresist, which is used on the bomb proof Garrett turbo Range so these are true high spec units.  These turbos have been testing on road and track since late 2018 and have easily proven themselves durable and without compromise on power, reliability and especially response.

Fully Cast in the UK and hand finished with all Genuine High Grade K04/16 components these Custom Made units come fully guaranteed to blow the competition away.

For the very best in performance for the ST180 1.6 EcoBoost there is only one number you need to remember,


The X57 was designed to be made is a few different internal sizes to suit various power requirements. The 2 sizes Pumaspeed have chosen work to give that perfect balance between spool and power depending on how far you fuel system and engine internls will allow you to push. Please select the unit that most suits your application and hardware already fitted to the vehicle. We are constantly listening to the customer and if demand is high enough we could even re-cast the exhaust housing to add flow but this would make the turbo too laggy for road useage.

Turbo and Power Sizing Made Easy.
To run the power below reliably please ensure your cars build specification is close to the Pumaspeed Recommendations below.
A fully Forged and Linered Block ( Pumaspeed Blue Top Engine ) is not essential,  415 bhp has been achieved on a totally Stock motor in the UK and 410 whp on USA spec Fiesta ST. However for repeated track and motorsport use above 380bhp ( U.K. bhp rating ) the limits of the stock Rod and Piston combination is very questionable, so we do advise these are swapped for engine longevity.
