Now I been thinking about a twincharged grand prix and just looking for any information anyone has. I would prefer information thats useful and not information like. "Don't do it its not worth it." or "Stupid idea" I don't care if you don't like that idea I am just throwing the idea around. Also, how dependable would a ebay turbo kit be.

there are a couple I looked at.

Again helpful information not shi*ty info.

Also, I was thinking if I were to do this I would go back to stock pulley size for the Supercharger and run low boost on the turbo at least until i know what compression is running at and scan for KR. I heard of a guy doing this around my area unfortunately he moved on to bigger and better things and sold all of his stuff. I suppose if you guys don't have any information I could find him and ask him a few questions. Figured it would be easier to stop in here.
