About $15k worth of upgrades and likely less reliability than a great F/I kit that will get you more for less.
300 NA HP can be achieved on the S2000 with a 2.4L stroker kit, ITBS, full exhaust (including header), head work, cams, engine management (not in the form of Emanage, but an AEM EMS) and ONE HELL OF A TUNE. None of these parts individually will increase power dramatically. You cant just throw in cams and expect 15hp or throw on an exhaust and expect even 5hp.
It is very expensive and not very reliable due to the sensitivity of the ITBS. ITBS will not significantly increase HP and TQ alone, but will improve throttle response and compliment the stroker kit nicely. An upgraded clutch and lightened flywheel will not do anything for performance in terms of power, but will lower the rotational mass and improve throttle response (noticeably while rev matching during a down shift).

And do us all a favor. USE THE SEARCH FUNCTION! It works very well and 99.9% of the time you will find what you are looking for.

On my previous setup I was making ~270 at the crank with only bolt-ons and tune. Intake, throttle body, cam gears, header, high flow cat, exhaust and tune.
With Toda Spec A2 cams and better intake you could surely make 270-275.
From there you can do a custom intake manifold or ITBs and head work. 300 crank HP is achievable. 300 WHP is another league though...
One guy on here in addition to gzod (although he looks about maxed out) may get pretty close, his motor is being built now.

That's 300 (nearly) HP to the hubs not the wheels.

There isn't a terrible difference between power at the hubs and power at the wheels. A negligible amount at most. Probably 7-10hp depending on unsprung weight. Part of that difference can even be attributed to traction and other variables that make a dynojet less accurate.
I dynod on a pak and a jet and got 30 hp difference.

Stroking the motor past 2.4L I think really changes the character of the motor. It's not just going to be more of the same which is what you get from most NA mods such as header exhaust head work etc. You will be dramatically shifting your power band down and reducing your redline (if you want to maintain any semblance of reliability). I'm not saying it's a bad thing to stroke, just that it's different from trying to create a more perfect F20C or F22C.

i 'm thinking of doing a engine swap: f20c to a acura nsx motor. i've seen on a dyno,the nsx motor put down stock 240 whp& 180 ftlbs of torque. the torque stayed at 180 from2 grand to redline. and the sound was music to the ears. this combo would make for a interesting S. otherwise ,big bucks to hit 300 whp with a n/a f20c.

Iv'e seen some crazy swaps, it shouldn't be any worse than some that iv'e seen. my god if someone can cram a 350 small block in a miata, i think a v6 should be doable in a S. HEY S2KRAZY2, have you boosted your s yet? last time we talked @ deals gap, you were going to go f/i.
