Vortex your looking at roughly around the $7000 mark, not intercooled, last time i checked. Its shit all power compared to that of a turbo running off unused exhaust gases. Also, boost on a vortex supercharger is extremely limited, and to up the boost, would involve buying a bigger supercharger in some cases. However vortex build some very reliable and safe kits for the b18c, b16a. Talk to capa performance, they know everything about them.

The turbo setup should be good. For around 4-7psi. Anything above, and it could be causing problems. A good friend of mine has a turbo teg, just like yours. Has been running 5psi, and driving it quite hard for a few months now. No problems what so ever. But he spent quite a bit on tuning.
