Of course it will, even standard brakes are fine..
How hard you brake is dependant on how fast you are going, not how much power you have, also no matter how much power you have your top speed is still limited by your gearing..
So basically if you find your brakes burning out because you are going too fast, and stopping too quickly repeatedly, then upgrade. Otherwise there is no reason you can't run 500kws and stock brakes, which on a skyline are pretty good from the factory..But yeah it is dependant on your driving not your power
