Installation Tips
Overview
When building a K24Z motor, such as those in the 9th Gen Civic Si or TSX, to produce high power and rpm over 8000, the factory oiling system becomes inefficient and problematic due to the balance shafts used by the OEM oil pump. The most common and cost-effective solution for this is to swap in an Acura RSX Type-S PRB oil pump to eliminate the balance shafts and improve oil delivery.

- Oil Pump Block-Off Plate

- (3) Stainless Steel Socket Head Cap Screw Bolts

Before You Order
〇 Regarding Import Duties
At Shaftoya, we pay the import duties incurred during customs clearance on our end, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm whether or not these parts can be installed on Japanese domestic market (JDM) vehicles before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and model using the tabs on our homepage, this does not guarantee that the product will fit Japanese-spec models without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before placing your order.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when 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 shipping cost for large items such as body parts. In such cases, we will contact you individually via email.
All products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork for these systems. Therefore, all parts are sold for "circuit use, private land, or off-road use only," and installation and usage are at your own risk.
○ Regarding Warranty
Please inspect your items immediately upon arrival. As all products are shipped internationally, there is a possibility of damage to packaging boxes or the products themselves during transit. We will provide returns, refunds, or exchanges only if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
