Mazda F2T specs: 2.2L (133 ci) 4-cylinder, 86 x 94 mm (3.3858 x 3.7008 in) bore and stroke, 7.8:1 compression. Rated 145 hp, 1988–1992. Used in the Mazda 626.
The Mazda 133ci (F2T) is undersquare — the 3.7008" stroke exceeds the 3.3858" bore by 8.5% — a layout that trades peak RPM for leverage and torque low in the range. The 3.7008" 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. Each of the 4 cylinders displaces 33.3 ci (545 cc).
7.8:1 is low by modern standards and generally happy on regular pump fuel.
