WHY Comptech Supercharger
The other thing you have to realise about the SC is that it's not about setting the lowest 1/4 time, or dragging every bass thumping rice burning 4 banger on steroids off the road. If you want that, there are much better ways of achieving it and they don't start with a $32K S.
Nitrous is great, but only for a short spurt of drag racing. Turbo's are great, but you've gotta do a lot of plumbing all about your engine bay, and then you got to address lag, but not over run the turbo, yadda yadda yadda.
The absolute beauty of the Comptech kit is that it really is a bolt-on (and bolt off when you are selling your S) kit, that delivers a great, and yet managable amount of power, all day, everyday, with out negatively affecting the drivability of the car (just put a wooden block under the accelerator when you give the significant other the keys
).
It's fairly apparent that one thing a lot of less experienced motorists don't understand is balance. Some times more isn't better, and most isn't best.

nwk00,
I saw the Top Fuel car last time I was out in Japan nearly a year ago. At that time they were doing 380ps. I've read that they were doing well beyond this number in some magazine a while back. I'm sure they are probably closer to 500ps by now, but I just threw the 400ps number out as an approx.

Ben, yes there is a intercooler, it would obviously be custome built probably using an Apexi core. As for booost, that would be determined later but probably around 4-5 PSI. As for gauges, I'm trying to stay away from any cockpit gauges as not to 'announce the presence'. I appreciate your input on this. I am, however, not sure that you currently appreciate my mechanics competence. They are currently talking with GM (General Motors) about the turbo kits they fabricated for the Sunfire/Cavalier which was at the last SEMA show. They have done many custom set ups over the past several years. However, the biggest problem I feel with the turbo (after everyone's input) is the engine in the S2000. I just don't think I have the faith in it to turbocharge it. If I do anything, I'll think I'll go with the Comptech kit.
Thanks VA S2K, wow lots of data. Is a clutch upgrade recommended in addition to the headers and exhaust?

$4900.00 for a centrifical supercharger and all the testing that has gone into it to ensure reliability of the motor and still produce at least a 35 percent horsepower gain , is a pretty good price. Nitros is a fad which is impractical for normal street applications. It does produce massive gains but at the cost of abrupt power response well above normal cylinder pressure and durability problems. Reputable turbo packages still have problems with non-linear power delivery (alias; turbo lag), which is not condusive to good low end response. Double this with a nitros system and your looking for on-off performance. Most young tuners do not take in conisderation the enormous cylinder pressures there dealing with. Bottom ends, con rods, pistons, valve trains need to be strengthen to accommidate these increased pressures. Things you have to consider when selecting the latter. It's a risky proposition for a automobile running 11:0.1 compression. Most turbos have to produce enormous pressure to equal a supercharger in low end response and overall performance gains. This has been an inherent problem for decades. Bottom line yep, 4900.00 is well worth the investment and piece of mind.

The mods I have made are all about trying to get a bit better throttle response and low end power (without losing on the top), so this particular change may be counter to my efforts.

5200 rpms?!? did you look at the dyno printout? There is power from 3500 and up. By 5000 there are ~25 hp and ~20ftlbs gains.

COOL!
