F20C & F22C - Honda S2000 Head Gasket Keychain

This stainless-steel head gasket keychain celebrates Honda’s legendary S2000 engine family: the 2.0-litre F20C and the later 2.2-litre F22C/F22C1. The F20C is correctly known for its 9,000 rpm redline/fuel-cut character—a defining feature of the original AP1 S2000.j

Engine Identity

Manufacturer: Honda Motor Co., Ltd.
Engine codes: F20C; F22C; F22C1.
Configuration: Longitudinal, naturally aspirated, water-cooled inline-four petrol engine.
Cylinder count: Four cylinders; DOHC, 16 valves, VTEC.
Displacement: F20C: 1,997 cc / 2.0 litres; F22C/F22C1: 2,157 cc / 2.2 litres.
Production period: 1999–2009.
Original application: Honda developed these engines specifically for the rear-wheel-drive Honda S2000.

Honda’s original April 1999 S2000 technical release identifies the F20C as a longitudinal water-cooled inline-four with a 1,997 cc capacity, DOHC valve gear and a chain-and-gear-driven camshaft system. The related F22C retained the 87.0 mm bore but used a longer 90.7 mm stroke to raise capacity to 2,157 cc.

Vehicle Compatibility Matrix

Engine	Vehicle	Chassis / market	Years fitted	Factory context
F20C	Honda S2000	AP1, Japan	1999–2005	250 PS at 8,300 rpm in the original Japanese-market specification.
F20C	Honda S2000	AP1, North America	2000–2003	2.0-litre S2000 engine, rated at 240 hp for this market.
F20C	Honda S2000	AP1 and AP2, UK, Europe and Australia	1999–2009	The 2.0-litre F20C remained the engine supplied to these markets.
F22C1	Honda S2000	AP2, North America	2004–2009	Longer-stroke 2.2-litre variant developed to improve torque.
F22C	Honda S2000	AP2, Japan	2006–2009	Japanese-market 2.2-litre development of the F20C.

The F20C/F22C keychain is intended for S2000 enthusiasts rather than as a claim that every engine code used an identical service gasket. Confirm your engine code and market if you are buying it as a vehicle-specific keepsake.

Why This Engine Matters

The F20C made the S2000 exceptional by delivering 250 PS from 1,997 cc in Japanese specification—125 PS per litre—without turbocharging or supercharging. Its 9,000 rpm redline/fuel-cut point, 8,300 rpm peak-power speed and naturally aspirated VTEC power delivery made it one of the era’s defining Japanese performance engines.

The later F22C/F22C1 increased stroke from 84.0 mm to 90.7 mm, prioritising a broader torque curve while preserving the S2000’s high-revving identity. This is why the F20C is usually associated with the sharper, 9,000 rpm AP1 experience, while the F22C is associated with the later, more torque-focused AP2.

FAQ

Is this keychain for the Honda S2000 F20C?

Yes. This design celebrates the Honda F20C, the 1,997 cc, four-cylinder DOHC VTEC engine fitted to the original AP1 Honda S2000.

Did the F20C really rev to 9,000 rpm?

Yes. The F20C is correctly associated with a 9,000 rpm redline/fuel-cut point; peak power in the original Japanese-market S2000 was produced at 8,300 rpm.

What is the difference between the F20C and F22C?

The F22C/F22C1 uses the same 87.0 mm bore as the F20C but increases stroke from 84.0 mm to 90.7 mm, raising capacity from 1,997 cc to 2,157 cc and delivering more mid-range torque.

Is this a functional engine head gasket?

No. This is a decorative stainless-steel keychain inspired by the Honda F20C/F22C head-gasket profile; it is not a replacement engine component.
