The F20C and F22C1 were inline-4 engines produced by Honda for use in the Honda S2000. They are one of the few Honda 4-cylinder automobile engines that are designed to sit longitudinally for rear wheel drive. These engines are related to the F-series engines found in the mid-1990s Honda Accord and Prelude. [1]

This engine was a radical departure from previous F engines, and only shared basic dimensions such as bore spacing. It was designed specifically for the Honda S2000 and shares some engineering with the Honda K engine. A long-stroke F22C1 variant was also produced.

Let’s compare the F22C and F20C, and find out the main dif ferences. Honda engineers installed a new 90.7 mm stroke crankshaft, 149.65 mm long rods and 29 mm high pistons into the F22C cylinder block.

Apr 26, 2023 · The most significant change is a new engine, the F22C1, with 2.2 liters of displacement. The F22C1 has a 90.7 mm longer stroke, reconfigured camshafts, a higher 11.1:1 compression ratio, and...

Dec 1, 2021 · By reconfiguring the F22C's camshafts, Honda now delivered a motor that maintained 240 hp, but at a lower 7,800 rpm, matched with a 10 percent torque boost when cruising from 2,500 rpm onwards (topping out at 162 lb-ft at 6,500 rpm)

Used solely in Honda's S2000, the F20C/F22C is an engineering marvel. This engine is, horsepower per litre, the most powerful engine offered in any production vehicle for the USDM.

Jul 24, 2015 · The Honda F20C and the F22C were the engines chosen to propel the AP1 and AP2 S2000 roadsters (respectively) that were released in celebration of Honda Motor Corporation’s 50th Anniversary. These engines featured a staggering 9,000 RPM redline, VTEC, roller bearing cam followers, chain driven cams and the highest mean piston speed of any ...

Jan 22, 2008 · Both engines have been shown to respond equally well to forced induction from what I've seen. F22 has more natural midrange potential with the torque boost from the longer stroke. I guess it really boils down to the character you want in your car: peaky or mid-ranged.
