:slap: This might be a dum question but I have compare the 04 & 06 S2K, find there is no difference on HP nor Torque, can anyone give me lil idea y Honda change it to 2.2 from 2.0, also is the engine no. still the same F20C? alsoooo, does the Hard top fit onto 04's as well?
The Diffrence~ The first S2000s (2000 to 2003 models) came equipped with a 2.0 L (1997 cc) F20C inline 4 cylinder engine producing 240 hp (179 kW) at 8,300 rpm and 153 ft·lb (208 Nm) of torque at 7,500 rpm, though the Japanese models were quoted with additional 10 hp due to a small difference in engine compression ratio. Because of its high-revving nature (9,000 rpm redline for the 2000 to 2003 models and 8,200 rpm for the 2004 model onwards), it is one of the few naturally-aspirated engines to produce over 100 hp/L. The compact and lightweight engine, mounted entirely behind the front axle, allowed the S2000 to obtain a good front/rear weight balance and low rotational inertia for improved handling. Following criticism about a lack of low-down torque, Honda introduced a variant of the F20C engine to the North American market in 2004. Designated the F22C1, the stroke of the motor was lengthened, increasing the displacement to 2.2 L. As a result, the redline was reduced to 8,000 rpm (mandated by the longer travel distance of the pistons). Peak torque was increased by 6%, and the F22C1 was quoted by Honda as having more torque at lower rpm than the F20C, although officially the power output remains the same between the two engines. Initially, the F22C1 was intended only for the North American market, but it was also introduced to Japan in 2006. At the same time as introducing the F22C1, Honda also changed the transmission gear ratios, by shortening the first four gears and lengthening the last two. Another change was the inclusion of a clutch release delay valve to improve drivetrain longevity by reducing shock loads.
