i wouldn't even supercharge an nsx, the car has high compression and is meant to go all motor. any form of forced induction is stupid.
if you have an nsx and you are worried about getting more power then you are crazy.
Then I guess my 600 crank hp NSX makes me several levels beyond crazy.
There are several options for bumping up the power on an NSX. Obvioulsy, you can spray. That is the cheapest solution, but is limited in that you can only run the N2O for a few seconds.
Turbocharging is a popular option (and the one I chose). Corkey Bell makes a TT kit based on the little Aerodyne turbos. They will get you 260-380 hp at the wheels is set up correctly. They spool up pretty fast. The kit is about $10K. I use a completely custom turbo set up with Motec engine management.
Comptech makes a Whipple-based supercharger kit that sells for about $0K and gives you 340-360 hp at the wheels.
Mark Basch is about to release a Paxton Novi based kit that will sell for less than $6K and gives 360-400 hp at the wheels. Unless you are looking for gobs of power, I think this is the way to go. You can see it at

Lastly, Gruppe M makes an Eaton based blower kit that costs about $10K and makes power somewhere between the CT kit and the Bell kit.
