Raptor might be able to help you with their supercharger kit. Be prepared to spend some $$$ iirc there kits for the previous Gen legacy were around $4k, and added 70 ish whp.
AVO made a turbo kit previously but I've not heard much about it.
If money isn't a factor for you, save your money and get a turbo car. You'll be happier in the long run with your mods and their effectiveness.
