Some of you may have seen the first supercharged b16a project. See here

I've since supercharged a Honda B18c and a B20/Vtec.

Check out my supercharged B20/Vtec build at NZHondas.com

The build was done on a stock bottom end B20B mated to a stock B16a2 head using stock headers and exhuast etc. The only change was the injectors from stock 240cc to Mitsubishi 450cc blue-tops.
The gains that were made are the bare minimum due to the restrictions from using the factory equipment . . . not a bad gain for doing it on the cheap

Here's the dyno results showing the comparison between the stock B20/Vtec with no S/C and with the S/C
