Nissan's own uprated water pump for the RB engine is designed to handle the high power, high performance demands of the N1 R32 GTR, which dominated so much of motorsports in the late 80's/early 90's. Known colloquially as the N1 water pump, it features a revised design to better handle extended periods at higher RPM. A revised impeller and backing plate reduce the chance of cavitation at high RPM, optimising your cooling system. A must-have if you regularly use your Skyline on track.
