Honda F20C engine

The Honda F20C and F22C engine is unrelated to the F-series found in the Honda Accord. It shares many properties with the K-series, and it is said (but yet unconfirmed) that the cylinder heads from the K-series and the F20C S2000 engine are interchangeable. It is the only Honda engine that is designed to sit longitudinally for rear wheel drive.

The F20C was designed with high maximum RPM in mind, for increased power output; redline is at 8900RPM, with VTEC engagement at 6000RPM. Power output is 240hp (179kW) at 8300RPM.

The F20C's bore is 87 mm and stroke is 84 mm.

Applications:

* 2000-2003 Honda S2000 (USA)

* 2000- Honda S2000 (Rest of world)

F22C1

The F20C was stroked (to 90.7 mm) to bring displacement to 2.2 L for the US market. Redline was reduced to 8000RPM; power output is claimed to be identical to the F20C, although dynamometer sessions indicate it is higher.
