Yeah, I knew powertech was good, but as far as I've heard (and this was from one of the manufacturers of after-market turbo kits), the Spec V's engine does not respond very reliably to turbocharging. When it is turbocharged, the boost is usually very low (5 to 8 psi) and produces roughly about 75 - 100 extra wheel horsepower. However, the engine does not react well to early turbocharging and so Area 51, for instance, has yanked the kit it was supposed to release for the Spec V. Since 2003 there are about 3 places that you can go to for your forced induction needs: Travis, SSR, and Power Tech Imports.
