F20C

• Displacement: 1,997 cc (121.9 cu in)
• Compression: 11.7:1
• Bore: 87 mm (3.4 in)
• Stroke: 84 mm (3.3 in)
• Rod Length: 153 mm
• Rod/stroke ratio: 1.82
• Power:
  • JDM 250 PS (183.88 kW) @ 8,300rpm & 22.2kgm (217.71 Nm) @ 7,500 rpm
  • USDM 240 HP @ 8,300 rpm; 153 ft lb, 207 Nm @ 7,500 rpm
• Redline: 9000 rpm
• VTEC: 6100 rpm

The F20C was designed with high maximum rpm capability in mind, for increased power output; redline is at 9000 rpm, with VTEC engagement at 6000 rpm. Its relatively short stroke of 84mm results in a mean piston speed of 4965 ft/m, 56.42 mph or 25 m/s, higher than any other production car to date. Power output is 240 bhp (179 kW) at 8300 rpm in North America and Europe. The Japanese version, which has a higher compression ratio, is capable of 250 PS (247 bhp) at 8600 rpm. Honda's F20C Engine won a spot on Wards' 10 Best Engines List four times, in 2000, 2001, 2002 and 2003.

The engine displaces 1,997 cc (121.9 cu in), lending to the Honda S2000's name. This method of naming follows suit with the rest of the Honda S roadsters (i.e. Honda S500, S600, and S800).

Applications:

• 1999-2005 Honda S2000 (Japan)
• 2000-2003 Honda S2000 (F20C1) (North America)
• 1999–2009 Honda S2000 (United Kingdom, Europe, Australia)

The F20C produces the highest specific power output for any naturally aspirated 2.0L piston engine in a car priced under US$100,000, at 123.5 hp (92.1 kW) per liter, ahead of the SR16VE N1 found in the homologation version of JDM Nissan Pulsar producing 197 bhp (147 kW) for a specific power of 123.45 bhp (92.06 kW) per liter. The F20C held the record for producing the highest specific power output for any mass production naturally aspirated piston engine until Ferrari released the 458 Italia in 2010, which produces 124.5 HP/L.
