IIRC there is no way to increase the fuel pressure on the DBW cars as they use a returnless system and no FPR. Here is the system from Ct-engineering for 06+, so they have a solution. It says something about a new ACM and re-flash needed.

If you are ready to transform your S2000, the CT-Engineering After-cooled Supercharger kit is a great start. This supercharger kit utilizes the benefits of a centrifugal supercharger, and is designed to match the factory power characteristics of the high revving Honda 2.2L power plant. The CT Engineering after-cooled Supercharger kit will add more power to your S2000 at the higher RPM's, keeping the car drivable in traffic & day-to-day driving; but throttle the engine to redline & you'll feel the burst of acceleration from the additional 70-80 horsepower at the rear wheels.

This simple bolt on kit utilizes a very efficient gear driven centrifugal supercharger. Included in the kit is everything you'll need to transform your S2000 into a Boxster killer, with 310-320 horsepower at the crank. The kit is CARB legal and includes the blower unit, after-cooler, after-cooler radiator, water pump, all mounting brackets, computer system upgrades (including the new CT Engineering ACM Unit, and Hondata ECU Re-Flash), air box, all hoses, and a new drive belt. Cooler housing is designed with popular blow-off valve bolt pattern on by-pass valve outlet, for those who want to run higher than standard boost levels. Note: Warranty is void w/ higher than standard boost level, and electronics will need to be replaced with a programmable ECU.

This kit is designed so that it can be removed without any modifications to the factory components.
