The factory water pump included with Nissan RB20 / RB25 / RB26 engines is not designed for racing applications. By removing the factory pump, which easily cavitates at high RPM, and installing this EWP Electric Water Pump kit, you can achieve highly precise control over coolant flow rates.

Compatibility:
  • RB25 engine
  • RB26 engine
The kit includes everything necessary to install the electric water pump.
  • Aluminum water pump delete plate
  • Billet aluminum -16AN thermostat outlet
  • Water pump gasket
  • EWP150 electric water pump
  • EWP electric pump controller (optional). A standalone unit that does not require computer-based pump control.
    Since this controller is powered directly from the battery, it allows for control of the water pump and fan even while the engine is off.


Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

Checking Compatibility
Our entire product database is based on North American vehicles (USDM), so please verify compatibility with your Japanese vehicle (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our top page, it does not necessarily guarantee that they will fit Japanese models without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.

○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual cost for large items such as body parts. In such instances, we will contact you individually via email.

Generally, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm the estimated delivery time. Note that all products are transported by air; sea freight is not used.

○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural review documents or similar certifications for this purpose. Therefore, all parts are sold for use on "circuits, private property, and off-road" use only; installation and use are at your own risk.

○ Regarding Warranty
Please check the contents immediately upon arrival of your order. Since all products are shipped internationally from outside Japan, there is a possibility that packaging or products may sustain shipping damage. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defects, or incorrect items if you notify us within 7 days of receipt. Furthermore, for products sold through our company, warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan for these matters.
