NoSweat is right. Basically if you want to go turbo you will have to keep boost levels really low in order to not blow up your engine. The gm supercharger puts out a low level of boost that is safe to use with a stock setup. The reason I went the supercharger route is its a gm product that has been tested and has been proven to work. Plus gm will service the supercharger. On the other hand a custom turbo may give you better overall performance but there is no telling what its going to do to your engine.
By the way Nosweat I like your car. I wish I had the quad 4. That is a really sweet setup you have.
