you can use the header from the gst/gsx, but you will not be able to run the t3/t4. its too big and will hit your a/c. you'll have to use a 16G turbo, which is just as good, if not better than the t3/t4. its smaller, allowing it to spool up a bit quicker, and its durability has been long proven. you will also need to get the oil feed fitting welded to oil pan. any good welding shop can easily do this. also youll have to get the e-manage tuned. find a good car shop with a dyno to do this. hardest part, if you buy a kit, is taking off the front bumper, but from there on out, its (with a kit) a bolt on job. you didnt say if its auto, manual. also you need bigger tires. 225's should work. there are so many more things you can do, but you better have a big budget.
