in the R&C forum they speculated that the lower gearing in the 04 (2ndary reduction gear) equates to about a 4.3 in a 00-03 s2k.

my guess is that with a 4.44 js swap an 02-03 can hang right there with an 04 if not get ahead of it, from a dead stop that is.

I'm going to take the 04 and my car out for some interval testing tomorrow in various gears. That will also be part of the article at vtec.net
Hey UL, as long as you've got the car do they allow you to reconfigure anything at all? Like the front end alignment? As part of your official TOV testing it would be nice to hear your impressions of the impact of a bit more aggressive set up since it's such a minor thing to do.

Not really supposed to do that stuff since it would make the car non-representative of production models. I've got to give the car back soon anyways and won't have time for an objective handling comparison before then (read no more auto-x available in time).

On the gearing, according to the numbers the 04 is geared about 3.7% shorter in the first 4 gears. That would to about a 4.25 gear on the 00-03. The reason it feels even shorter is the reduced redline. Frankly, I think the car would be better with taller gears, or at least the same gears as the 00. As is, the car lights up the tires in first very easily and will get really sideways on a hard 1-2 shift.

If you have an AP1 car and have driven the AP2, you know the power is there. If you have not spent a good amount of time in either one, you hardly know the difference or need to speak endlessly about it. Not trying to be a fist, it's just that damn... This thread is wearing thin. Notice how Shawn's typos grow as the replies continue... I mean, are some of us arbitrarily trying to bate him? Let's enjoy folks. The dyno is an A vs B deal, end transmission!!!!!

I drive my 02 most of the time, I run synthetic, only use BP 93 Octane.. yada yada yada... As soon as I released the clutch on the 04, I knew... Much hotter S2000 set-up, the car is faster... We haven't even made it past the "green engines" stage. The car has a lot more "getty up". On an easy U-turn the car was shredding tire in the rear, this is defnitley a new S2000. Also, a lot of F20's lost their lives for the the F22, after driving I think current F20's would be proud of their martyrs. No I am not selling my 02, but honestly... I think it's the lack power I prefer, the ease of which I can hang the F20C in all levels of RPM without all hell breaking loose=MAJOR DRIVING FUN. With the exception of my miss-shift around 600 miles when popping the cherry, I never hit my rev limiter until I chased an M3 through some extremely tight twisties. The F22c does not drive quite like this, it wants to run to redline. Different car. I bashed the rev limiter 3 times when I drove it, the same happened when I drove the 03 Civic Si which cuts at like ~7300rpm. "Not" speeding will be much more of a hassle in the new car.

But hey, I love the opposite about my 1986 VF500F Interceptor, the bike revs to 12,500RPM, but it's a relaxed and flexible rev to redline. You can hang it up anywhere and it loves it, simialr to F20C. The F22C is a get on or get off type of feel, much more of the traditional American type sports car. I've rode both the 700&1000cc versions of my bike, much faster but just not for "me", I'm on the lookout for the old 400cc monster(you know the one). If the AP2 car is not better than the original, it's production is moot. Can't we all just rev along...?

Gosh I guess this is a dumbed down, softened s2000.....Can't really argue the numbers.

Something seems a little fishy with the dyno numbers. Why is the MY04 only losing 2.5 ft lbs(158.5) of torque from the claimed (162) from Honda. But the MY00-03 is losing 19.6 ft lbs (138.4) of torque from the claimed (158) Honda. I understand that you lose some when seeing it at the wheels, but why would one (MY00-03) lose soooooo much more than the other (MY04)? Shouldn't they both lose about the same percentage of torque?

I'm going to ignore the numbers for a second here and pose this to you:

The 2.2L is unique to the North American market correct? ie: The European and Japanese versions still keep the 2.0L?

If that's true then:

Why the hell would Honda release a car to a foreign country with so much more power than its domestic version? Japan is one of the centres for automotive technology and performance. With all the other companies sending "watered down" versions to North America, why would Honda go against that and send the big performer away to somewhere else and not keep it for themselves? It doesn't make sense.

Just a thought
