This is pump fits R32,R33,R34 RB26DETT and R33 R34 RB25DET engines.
This is not the factory RB26 or RB25 water pump, this is the N1 water pump found on the R34 GTR N1 Engines.
The N1 water pumps have a 6 blade impeller. The blades are much larger than the OEM water pump blades. This aides in coolant flow, and eliminates cavitation at higher RPMs.
This water pump is great for those that need of better coolant flow. Perfect for Drifting or everyday street driving.
