However, none are readily available on the market for S2000's.

Most are centrifugal blowers..... more revs -> more boost.
Thats whys they developed the Twin Screw type. Max boost pressure @ 2500-2800rpm. Also can be intercooled. Much more reliable and hassle free than turbo if your looking to add another 100-150bhp.
