Ummm, 2005's are AP-2's.

I think he is in Japan and the 2005's were still 2.0 liter 9K engines, I think but with the AP2 chassis.

I live in Hong Kong, but yes you are correct my s2000 is imported from Japan... so 2005 (my friends) and 2004 (my car) are both 2.0L 9k engline with AP2 chassis...

Yes I have been driving them back and forth the same road... all 4 different s2000 including mine...

I ran a 13.4 on my first run, and he ran a 13.8. They were both fairly new at the time though. We switched drivers, and he outran me in my own STI. Due to age of the vehicles though, this may not apply. Best advice above, dyno runs on same dyno back to back, or race on a closed course.

I guess this could be true too, but would u think the valve adjustment will make up the difference?

You could try it, along with a full tune up. All these cars are completely bone stock right? No exhaust,intake, or any other even mild modifications right? No additional weight from removal or addition of items? All cars replaced with the same exact OEM parts (exhaust, plugs, air filter ect ect. Too many factors to come up with an answer really.

Like I said before, every car is slightly different coming out of the factory. Some are a little faster, some are a little slower. That might be the case, as vehicles are not exactly alike when built, but due to age, it could be as simple as a tune up, or heck, maybe your valves, ect ect.

Yea these s2000 are mostly stock aside from rim, tires and suspension... except mine has just installed an exhaust recently but even before or after it still feels slower than others
