My car is 92 Honda civic si sedan with a B16A2 conversion out of a 97 EK Vti-R.

I bought like this and there is a water temperature gauge inside. everytime when i drive a lot the temperature on the gauge is about 95'C (degree). i think this is too hot. but for the water temp on the original speedo, it's sitting normal and also there is no smoke or vapor from the engine.

is the conversion usually come with the B16A radiator or still using the original EG one?
How can i check..........is the water temp guage problem or it's overheating...........?

confusing..........., thx guys!!
