The GenV WG45 HyperGate45 external wastegate is a motorsport-proven, cost-effective external wastegate that boasts the highest flow rate for this type of gate. The GenV provides an extensive user configuration, world-leading extended thermal performance, fatigue resistance, and class-leading flow performance, resulting in optimal control and longevity.
The Turbosmart GenV external wastegate is a thorough reworking of a classic, and the only feature carried over from the Gen4 series is the mounting orientation. In-house CFD optimized and validated for maximum flow and thermal management, the GenV series has more features, options, and performance than any other similar gate.
It is a direct-fit upgrade for all Gen4 Turbosmart wastegates and features a unique collar locking system, variable actuator cap and base for easy 360-degree reference hose routing, a strap-type V-band clamp, optional liquid cooling, 1/8" NPT reference ports, and comes with a full range of available springs.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred upon import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Compatibility Check
Our entire product database is based on North American vehicles (USDM). Please check whether the item can be installed on a Japanese vehicle (JDM) 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 investigate for you.)
If you 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 in 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our warehouse in the United States. Unlike domestic delivery within Japan, international delivery takes approximately 7 to 14 days, so please order with sufficient time. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air freight. They will not be shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, 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 Japan, there may be shipping damage to the packing box or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for products with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Furthermore, regarding products sold through us, we will handle warranty-related matters "only through us." Please note that we do not provide support through other companies or distributors located within Japan.
