GTR34

Hey I was wondering if my mustang makes more than 800 hp (just saying cause mine is stock right now) does it need the drag tires or can I leave the drift tires on. Also I was planning to twin turbo it with 2 83mm turbo but Idk if that is too much. I would appreciate it if someone can give me feedback on how to make my foxbody faster and if I need to put on those big tires
