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. This engine, unlike most F-series engines, has two counter-rotating overhead cams, a VTEC system for both the intake and exhaust camshaft, carbon-fiber reinforced cylinder liners, moly-coated piston skirts for reduced friction, and uses a cam chain insted of a rubber belt. It is the only Honda engine that is designed to sit longitudinally for rear wheel drive, with exceptions to the Acura Vigor G25A1(92-94) and the Acura TL G25A4(96-98). Even though these are branded Acura, Honda manufactured them in Japan for the North American market. These engines were longitudinally mounted even though they were front wheel drive vehicles. The transmissions were effectively folded in half, so to speak, and the differential was mounted on the left/drivers side of the car.

The F20C was designed with high maximum RPM in mind, for increased power output; redline is at 8900 rpm, with VTEC engagement at 6000 rpm. Power output is 240 hp ECE (176 kW) at 8300 rpm in Europe or 240 hp SAE (179 kW) at 8300 rpm in North America. The Japanese version, which has a higher compression ratio, is capable of 250 hp JIS (184 kW) at 8300 rpm. Honda's F20C Engine won a spot on Ward's 10 Best Engines List two times, in 2000 and 2001.

The engine displaces 1997 cubic centimeters, lending to the Honda S2000's name (1997 rounded to 2000). This method of naming follows suit with the rest of the Honda S-series.

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

 

In 2003, Honda produced a stroked (to 90.7 mm) version of the F20C, increasing displacement by 160 cc to (nominally) 2.2 L. Dubbed F22C1, it was originally designed for the North American market, and introduced for the 2004 model year. Rated torque increased from 153 lb

 

Where was that copied from Wampa?

Ant, great info, thanks. Id love another S2000 with ITB's and some other bits. Looks like a great job there. If im ever in the area id love to pop in. Will be in the Evo though

Mark, the Comptech is aftercooled so it should be fine and no real need for WI.

I think if I were going Comptech, id drop the aftercooler in favour of Aquamist. You then get the cooling and extra power, but dont get the pressure drop of the aftercooler system, which robs a psi or 2 of boost.

The G25 was used to power the SSM, before they thoght better of it.

It's a pity they ditched that layout - it would have been superb for SH-AWD in the Legend. Watch the ASCC!

 

I sometimes visualise Nick as this character for some reason

Sorry But WTF Are You Talking About

 

I shipped my ITR short block over to Laskey for a full build a while ago. You can get the shipping done for between

 

Mikey, Don't bother building the engine unless you are going to race you car or track it "alot".
For a supercharger application on a std pully (even an upgraded smaller pully) you wont be putting that much stress on the engine, all you need at most would be a 2mm cometic head gasket with a decent MAP from a decent tuner.
