I've seen people say that the needle doesn't move until 210F-220F. Basically you're already in trouble by the time it starts to move.
I do believe the stock thermo is 170F/76C, Billion High Flow is 149F/65C, Nismo is 144F/62.
Note that even though the Billion has a higher opening temp, it will allow more flow to the radiator than stock or Nismo.
