JTJA / JTJB 1.6 EcoBoost — the engine behind the Fiesta ST180

The Fiesta ST180 became one of Ford's most celebrated compact performance cars by combining low weight, sharp chassis tuning and a 1.6-litre turbocharged EcoBoost four-cylinder producing 182 PS.

The JTJA and JTJB engine codes identify the 1,596 cc ST-specification EcoBoost used in the Mk7 Fiesta ST. Ford's own parts catalogue groups both codes together at 134 kW / 182 HP, confirming them as members of the same ST engine application.

Unlike the larger Focus ST engines, the Fiesta's appeal came from a smaller, lighter package. The turbocharged Sigma-based EcoBoost engine gave the car strong mid-range performance while retaining the agile character that made the ST180 particularly popular with UK enthusiasts.

This GasketKeys piece recreates the engine's head-gasket geometry as a compact stainless-steel tribute to one of the defining affordable hot hatches of the 2010s.

Engineering & Craftsmanship

• Industrial Grade Build: Precision laser-cut from premium 304 stainless steel with a durable brushed-metal finish.
• Protective Frame: Presented inside a 3.3 mm CNC-machined PLY frame for protection and presentation.
• Technical Precision: Cylinder bores, coolant passages and major gasket features are digitally mapped from the original gasket geometry.
• Letterbox Friendly: The slim under-5 mm packaging format keeps UK delivery practical.

These construction details follow the supplied GasketKeys framework.

A subtle Fiesta ST memento

The ST180 has an unusually strong owner identity for a relatively modern Ford.

Rather than another large ST badge or logo, the gasket keychain represents the engineering underneath the car. To someone who knows the Fiesta ST, the four-cylinder gasket pattern is a subtle reference to the JTJA/JTJB engine that made the car what it is.

For current owners, former owners, tuned-car enthusiasts or someone restoring one of these cars, it works well as a compact engineering memento.
