Engine Variants
Honda F20C (Original)
The F20C is a high‑revving, naturally aspirated 2.0‑liter (1,997 cc) inline‑4 engine with a dual overhead cam (DOHC), 16‑valve design and Honda’s VTEC variable valve timing system, developed specifically for the Honda S2000. It features an 87 mm bore and 84 mm stroke with a compression ratio of around 11.0:1 or 11.7:1 that produces approximately 237–247 hp (177–184 kW) at around 8,300–8,600 rpm and about 208–218 Nm (153–161 lb‑ft) of torque at around 7,500 rpm. The engine is known for its exceptionally high redline of 8,800–9,000 rpm, lightweight aluminum block and head with fiber‑reinforced cylinder liners, and a 6‑speed manual transmission, making it one of the most celebrated naturally aspirated four‑cylinder engines of its time.
Honda F22C1 (Later Version)
The F22C1 is an evolution of the F20C that features an increased displacement of 2.2 liters achieved by lengthening the stroke to 90.7 mm while retaining the same 87 mm bore. This version maintains the DOHC 16‑valve VTEC architecture and uses an aluminum block and head, but it is tuned for stronger mid‑range performance with an output of about 237–240 hp at 7,800 rpm and enhanced torque of around 220 Nm (162 lb‑ft) at roughly 6,500–6,800 rpm. The longer stroke results in a reduced redline of around 8,000–8,200 rpm and a slightly revised compression ratio near 11.1:1.
