I Have been doing research for the past month on adding a turbo or a supercharger to my 2.0 (should have gotten a 1.8T). I have talked to people who have the supercharger, and they all say that a stock 1.8 whoops on them. Has anyone put the aftermarket turbo on their 2.0? I've seen places that the stage 2 gives you 200 hp. Any real life advice would be a great help.
