ISR Performance OE Replacement Water Pump - Nissan RB25/26

Finding a factory water pump for an RB engine has become harder and more expensive every year. The ISR Performance OE replacement water pump for the Nissan RB25DET and RB26DETT is a direct replacement built to OE specification, so you can service the cooling system on an R32, R33 or R34 Skyline or an RB swapped 240SX without chasing JDM parts.

What it is

• OE replacement water pump for RB25DET and RB26DETT only
• Built to the same specification as the factory pump
• Not an OEM Nissan part; an OE replacement alternative
• Designed exactly like the factory pump, with no paper gasket

Sealing note

Like the original Nissan pump, this one seals with silicone gasket maker rather than a gasket. Silicone gasket maker is required to complete installation, so have a tube on hand before you start.

Performance

The pump performs just as well as the original at a fraction of the cost of a dealer part. For a cooling system refresh alongside a timing belt job, it is the practical way to replace a tired pump on a street or swap RB.

Fitment

Nissan RB25DET and RB26DETT engines in the R32, R33 and R34 Skyline, and RB25 or RB26 swaps in the 240SX. Does not fit other RB variants.
