Put it this way had I bought a J&S when I installed my turbo I'd probably still be on my stock motor....two sides to that, I'd still be on a stock motor and would have a little fatter wallet and I would still be on my stock motor and probably would feel as safe running 20pounds of boost....I say get one its money well spent.
