Our Single Stage Boost Control (SSBC) kit consists of three components that allow for single-stage boost control. This kit includes an electric delay relay timer, one electric switching valve, one mechanical regulator valve, and illustrated instructions. When used together, these three parts provide the end user with one stage of mechanical boost control based on a timed delay relay switch. This single stage of boost control can be activated via a transbrake button or clutch switch and is compatible with almost any external wastegate that has two air ports. This Single Stage Boost Control (SSBC) kit has been successfully campaigned on numerous championship-winning turbocharged vehicles over the past decade.
Need additional stages of boost control? This kit can be customized to accommodate additional stages of boost control to suit your application.
Before Placing Your Order
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay 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.
〇 Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before placing your order. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle; 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 products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products 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 payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. In rare cases, there may be a significant difference 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 by email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please place your order with enough time to spare. If you are in a hurry, please inquire about delivery times in advance. Note that all products are transported by air freight; they are never shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength study documents or similar for that purpose. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside of Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, all warranty-related matters will be handled "exclusively through us." Please note that we do not handle matters through other companies or distributors located within Japan.
