There are many routes you can go to get what you want.
As far as the turbo goes... The GTP38R is a drop in turbo that will works great. If you are looking to expand your options, you can get a T4 style turbo and setup.
There really is no need to get a different intercooler. The stock one works just fine.
Any 4" exhaust system will work great for you. We carry Diamond Eye and MBRP.
As for injectors... We carry Full Force injectors and we have a lot of happy customers running them. You can go with stage 1's or stage 2's to get where you want. Stage 2's will open the doors for more power later if you want it.
We have a few different options for tuning. You can get a chip(F5 or F6), or you can get one of our Infinity programmers. The Infinity will do all you need and more. It will tune, monitor, datalog, read/clear DTC's, play media, test(buzz, cylinder contribution, glow plug, KOEO/KOER), and more. You can check out all of our options HERE
We can get you setup with a package deal including all of the products you listed too if you want.
