Ford 2.3 EcoBoost High Performance Package specs: 138 ci (2.3L) 4-cylinder, 3.444 x 3.70 in (87.5 x 94 mm) bore and stroke. Rated 330 hp, 2020–2023.
The Ford 2.3 EcoBoost High Performance Package is undersquare — the 3.7" stroke exceeds the 3.444" bore by 6.9% — a layout that trades peak RPM for leverage and torque low in the range. The 3.7" stroke puts mean piston speed at 4,000 ft/min around 6,500 RPM, which is where a production bottom end is generally considered at its limit. A rod ratio of 1.589 is in the range most production engines fall in. Each of the 4 cylinders displaces 34.5 ci (565 cc).
It is one of 5 engines in the Ford 138ci family, all of them 138 ci — the differences between them are in compression, heads and rating, not displacement. 4 factory variants share these dimensions, rated at 330 hp across 2020–2023.
