Honda F22B6 specs: 2.2L (131.6 ci) 4-cylinder, 85 x 95 mm (3.3465 x 3.7402 in) bore and stroke, 8.8:1 compression. Rated 140 hp, 1995–1997.
The Honda F22B6 is undersquare — the 3.7402" stroke exceeds the 3.3465" bore by 10.5% — a layout that trades peak RPM for leverage and torque low in the range. The 3.7402" stroke puts mean piston speed at 4,000 ft/min around 6,400 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 32.9 ci (539 cc).
8.8:1 is low by modern standards and generally happy on regular pump fuel.
It is one of 10 engines in the F-series family, the smallest at 131.6 ci. 3 factory variants share these dimensions, rated at 140 hp across 1995–1997.
