F20C

The F20C was designed with high maximum rpm in mind, for increased power output; redline is at 9000 rpm, with VTEC engagement at 6000 rpm. Power output is at 8300 rpm in North America and Europe. The Japanese version, which has a higher compression ratio, is capable of at 8600 rpm. Honda's F20C Engine won a spot on Wards' 10 Best Engines List four times, in 2000, 2001, 2002 and 2003.

F22C1

In 2004, Honda produced a stroked version of the F20C, increasing displacement by to . Dubbed the F22C1, it was originally designed for the North American market being introduced for the 2004 model year. Rated torque increased from at 7500 rpm for the F20C to at 6200 rpm for the F22C. The redline was reduced from 9000 rpm to 8000 rpm, mandated by the longer travel distance of the pistons. Peak horsepower output is rated identical to the F20C.

The F22C1 was used exclusively in the North American market for 2004 and 2005 with the F20C being used in all other markets. Despite the displacement increase, the car to which the F22C1 is mated retains the name of Honda S2000. In 2006, the engine fully replaced F20 engines in the Japanese market as well which resulted in a drop in rated power output from to due to compression being reduced from 11.7:1 to 11.0:1. The UK, European, and Australian markets are currently the only areas in which the S2000 retains the F20C.
