If it's your first boosted car/first skyline, I'd recommend just learning to drive it as is standard. Take it to track days and skid pan days and just have fun and learn the car. If it's a GTSt, just remember even if it's only making 140rwkw completely stock, boost + inexperience is enough to spit you out into a tree or someone else and kill you. If it's not your first turboed car, then go nuts lol Btw congrats on choosing the 33. By far my favourite of the skyline family and I'm on to my 4th one now
