Purpose and compatibility

The presented turbocharger has been designed specifically for the sporty versions of Ford vehicles with the 1.5 ST engine, used in the Fiesta Mk8 and Puma Mk4 generations. This ensures compatibility with the factory manifold, oil and coolant lines, and boost pressure control, minimizing the risk of installation issues. Its original Ford origin means that the geometry of the impeller, housing, and flow channels has been matched to the specific characteristics of the 1.5 ST engine, providing appropriate dynamics at low and medium RPMs and stable boost pressure under higher loads.

Construction and performance parameters

The turbocharger belongs to the Turbochargers and parts group, meaning it is an integral part of the forced induction system responsible for increasing the amount of air supplied to the cylinders. The construction includes a hot side (exhaust) and a cold side (intake), connected by a common shaft mounted on precision bearings. This solution allows for:

• achieving higher torque across a wide engine speed range,
• efficient acceleration without noticeable throttle lag,
• maintaining stable engine operating parameters during dynamic driving. By using an original turbocharger, compatibility with the factory engine control unit software is maintained, which limits the need for additional calibration after replacement.

Benefits of using an original Ford turbocharger

Choosing an original component with the Ford logo primarily ensures a perfect fit for the specific 1.5 ST engine configuration. In practice, this means:

• correct positioning of oil, coolant, and intake line connections,
• maintaining the factory boost characteristics without unwanted engine stress,
• easier diagnostics and future service, thanks to compliance with manufacturer documentation. The used OEM component is an attractive cost-effective solution while maintaining factory specifications, which is important both for post-accident repairs and for replacing a worn turbocharger in a daily-driven car.

Condition, identification, and selection

The product has assigned manufacturer markings and interchangeable numbers, which facilitates clear identification and selection for a specific engine version. It is worth comparing the markings with the removed turbocharger or vehicle documentation to confirm full installation compatibility. For additional verification, you can use the vehicle's VIN and manufacturer catalogs to confirm whether a given 1.5 ST engine configuration in a Fiesta Mk8 or Puma Mk4 uses this specific type of turbocharger.
