if thats the case, why when me and my buddy way2low punched it in a 2nd gear roll at the same rpm, i shifted a good second before my buddy did? same car almost same mods, except i have 4.77 gears, and we did switch cars and punched it at the same rpm and again he had to shift (in my car) way before I did (in his car).... hmmm 
You have shorter gearing. Cars 101. The gears will bring the engine to redline sooner at speed, but natural revving, as jfw calls it, is different - its effected by the mass of parts connecting to the engine.

Im sorry OP shouldve specified he was looking for something to improve nuetral revving. I was under the assumption that he wanted something to help his car rev up faster more freely while in gear.

Gears aren't going to make the car rev any faster, just move faster. Plus, I think 4.77 is a bit too high for the AP2, maybe the 4.57s.

than what exactly are the gears doing? its allowing the engine to rev more freely by giving a mechanical advantage. just move faster = quicker reving engine.....

Thanks BlownAP, Im glad someone doesnt think my statement wasnt complete fubar.
The enging does make it to the redline faster, at a lower speed. There are valid reasons to go gears, but reving faster is one of the downside of gears, not an advantage. Reving faster is more about throttle response.
BTW gears are the best Bang For The Buck mod you can do on the S2000.

The gears aren't allowing the engine to rev more freely. The gears move the wheels at a certain ratio to engine speed. When you change to more aggresive gearing, like 4.77 from stock, you change the speed ratio between engine and wheel rpms. I think you're confusing free-revving related to weight and inertia with speed-revving related to ratio.
if the OP wants an engine that is just going to free- rev easier than you are right, gear are not going to do it, the light flywheel and also lighter pulleys will, if he wants a car that is going to rev easier while in-gear. driving.... than 4.77's will do that.
the OP needs to specify his question.....

I would think that a lightweight flywheel would allow the engine speed to fall quicker when between gears so that you can engage the next gear sooner (at the correct engine RPM matching the drivetrain rotation). A lighter flywheel would also allow for faster rev-matching (quicker throttle response).
I get the impression when you guys say 'free-revving' that someone's just sitting in their car in a parking lot revving it up to 6 grand going "damn, that's a great mod... look how fast I can hit the rev limiter in neutral"
