Looking for a r33 gtr upgrade path!
 

This is my first skyline. I have around 60k miles on it I am looking at getting around 500-550 awhp. My car is completely stock. What will I need and what are my 1/4 mile times be around, if that is even possible to tell. Any help would be good. And I also take constructive advice also. Please tell me what will I need and where are good places to get them. I live in the United States. By the way my car is a 1995 R33 GTR. I just got it around 6 months ago.
