The problem with that is some of that stuff is specifically made for Buicks. Intercoolers are general application, you just need to make sure they physically fit on your car. Turbos as always are general application, unless they have a specific, non T based flange. Not to bust your balls or anything, just wanted to clear that up. None (or very little) of that kind of stuff designed for the GNX will work. Now, electronics, anything motor related besides mounts, manifolds, heads, etc should all work no problem.
T: Take the stock headers and try and flip them forward, see what you run into clearance issues with. I'd bet you're either going to have to run some funky piping or relocate some accesories to make it work, but I don't know for sure. Either way, can't hurt to try!
