Aisin RB26DETT N1 Water Pump to suit Nissan Skyline R32 GTR, R33 GTR & R34 GTR - RB26DETT N1.
The N1 water pump is designed to minimise cavitation produced through sustained high engine revolution. This doesn't make the pump superior to the regular Nissan item, simply that it is more suited to a race/track oriented vehicle.
