Hehehe.
I think it may be a bit earlier - I assume the bore of the motor will be increased, therefore the head of the piston will be slightly larger, weigh a little bit more, and therefore have more momentum which prevents it revving quite as high? Dunno, just guessing here.
Bit off topic but ....
Ever heard of Conrod Straight at Bathurst (Mount Panorama raceway) in Australia? Really long straight coming down a big mountain...one guess how that got it's name.

The F20C was designed with high maximum rpm in mind, for increased power output; redline is at 9000 rpm, with VTEC engagement at 6000 rpm. Power output is 240 bhp (179 kW) at 8300 rpm in North America and Europe. The Japanese version, which has a higher compression ratio, is capable of 250 PS (247 bhp) at 8600 rpm. Honda's F20C Engine won a spot on Wards' 10 Best Engines List four times, in 2000, 2001, 2002 and 2003.
The engine displaces 1,997 cc (121.9 cu in), lending to the Honda S2000's name. This method of naming follows suit with the rest of the Honda S roadsters (ie. Honda S500, S600, and S800).
The F20C's bore is 87 mm (3.4 in) and stroke is 84 mm (3.3 in).
Applications:
* 1999-2003 Honda S2000 (North America)
* 1999-2005 Honda S2000 (Japan)
* 1999-present Honda S2000 (United Kingdom, Europe, Australia)
The F20C produces the highest specific power for any naturally aspirated piston engine in a car worth less than US$100,000, at 120 bhp (89 kW) per liter, ahead of the 1.6 L (98 cu in) Honda B16B engine found in the 1996-2000 Honda Civic Type R producing 185 bhp (138 kW) for a specific power of 115.8 bhp (86.4 kW) per liter.
In 2004, Honda produced a stroked 90.7 mm (3.57 in) version of the F20C, increasing displacement by 160 cc (9.8 cu in) to 2,157 cc (131.6 cu in). Dubbed the F22C1, it was originally designed for the North American market being introduced for the 2004 model year. Rated torque increased from 153 ft

I have the 04-05 F20c engine, and had the F22c engine ... I understand what's the hype of the 9000rpm ... as well as the newly designed F22c, because the F22c really is a better engine.
Put together the two ... the 04 - 05 F20c engine really is the best I think. I love it ...

Don't forget the AP2 also has shorter gears for 1 through 4, which by themselves roughly mimic shorter final drives.
Throw a 4.70 on the rear end of an AP1 engine and you get redline shift speeds that are very close to stock AP2 redline shift speeds. With both engines, you're getting ~240 HP at redline. So for redline runs, you can basically expect AP2 setups to perform like AP1 cars with 4.70 gears through the first four gears. The AP2 has slightly more torque and slightly less RPM, the AP1 has slightly less torque and slightly more RPM. Total power to the wheels available at any given speed should be roughly the same.
But the AP2 can still gear down to those taller fifth and sixth gears, so you get all the acceleration of an AP1 with a 4.70 along with highway cruising that is even more relaxed than an AP1 with the stock 4.10.
In short, the AP2 offers the best of both worlds. I know it is thrilling to listen to that 9K AP1 redline, but the AP2 is a better setup in terms of performance and comfort.
