Honda F22C1 specs: 2.2L (132 ci) 4-cylinder, 87 x 90.7 mm (3.4252 x 3.5709 in) bore and stroke, 11.1:1 compression. Rated 237-240 hp, 2004–2009.
The Honda F22C1 is close to square: 3.4252" bore against 3.5709" stroke, within 4.1%, which splits the difference between a high-revving layout and a torque layout. The 3.5709" stroke puts mean piston speed at 4,000 ft/min around 6,700 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 33.0 ci (541 cc).
11.1:1 on aluminum heads is high enough that pump premium or better is normally required.
6 factory variants share these dimensions, rated from 237 to 240 hp across 2004–2009.
