I believe that the best help I, or anyone, can offer is to tell you to use the search feature on this site. Spend some real time looking at the builds you want to emulate, and do a lot of research.
I will say that milzy motorsports has a lot of good reviews from people here. I have never dealt with them myself, but they offer the parts you desire.

Tuning will be key. Learn about hp tuners. Or hire someone who can tune it for you.
It all comes down to money. Modding isn't cheap. Do you have fat stacks of cash you want to drop on this car? Turbos and tranny swaps aren't cheap. Most start with smaller stuff, and work up to a bigger project after learning more about the car and what's available, and what their skill levels are.
I will say "Welcome to the forums" and wish you luck in your search.
