Not knowing too much about N/A mods, but from what I've seen the best bolt-on N/A mods on a 2GNT will run you is into the mid 15's and the highest trap around 90-91mph. I think Todd (VX100) has run the highest trap speed for a 2GNT N/A at 91mph...correct me if I'm wrong. Comparing that to the latest edition of SCC with the RSXs on the cover, where they posted a bone stock RSX TYPE-S as running 15.0 at 94mph, you might be hard-pressed in beating him if it is a Type-S.
I'd say if you want to go for the best-bang-for-the buck route and something that can easily be installed in one sitting, go with a ZEX kit. One of my good friends had one on his '98 GS, before he bought a STAR kit, and I believe he could've easily been in the mid to high 14's. I think the kit goes for around $580, and can easily be installed in any driveway on any afternoon. The ZEX kit comes with its own fuel management which is another benefit. The whole time my friend was on the bottle the A/F never went lean, so it lives up to the hype.
Just be sure and go sleeper with the kit and route the line to the back side of the intake piping and covered with some black tape or wire covering. No doubt you'll smoke him then and he'll be scratching his head wondering what 'type-s' really stands for
