Installation Manual 

Elevate the performance and reliability of your Nissan RZ34 VR30DDTT with the HKS SUPER SQV4 (Sequential Blow-Off Valve). This advanced blow-off valve system features a unique two-stage sequential valve structure, utilizing primary and secondary valves to ensure optimal pressure management across a wide range of boost levels. Designed for precision and performance, the SUPER SQV4 enhances charge response, reduces turbo lag, and protects your turbos from unnecessary load.

Key Features:

• Advanced Sequential Valve Structure: The HKS SUPER SQV4 employs a two-stage sequential valve design, offering superior control of pressure throughout the entire boost range. This differential pressure control system allows the valve to operate effectively from low to high boost, ensuring smooth and consistent performance under all driving conditions.

• Relief-Less Operation System: Unlike conventional blow-off valves, the SUPER SQV4 suppresses relief during high boost scenarios, maximizing charge response and maintaining boost pressure during repeated throttle ON/OFF cycles. This design minimizes turbo lag and enhances overall throttle response, making your vehicle feel more connected and responsive.

• Dual Blow-Off Valves for VR30DDTT: The SUPER SQV4 kit features blow-off valves on both banks of the twin-turbo VR30DDTT engine. This setup quickly releases unnecessary boost pressure from each turbocharger, reducing strain and improving the longevity of your turbos, especially during aggressive driving and track use.

• Reinforced Silicone Hoses: The hoses between the turbochargers and the intercooler are upgraded to dedicated 4-ply silicone hoses specifically designed for the SQV4. These reinforced hoses provide superior durability and resistance to pressure, ensuring reliable performance under high boost conditions.

• Engine Bay Aesthetics: All components, except for the SQV4 main body, are finished in black, creating a sleek and integrated look that highlights the distinct appearance of the SQV4 blow-off valve in your engine bay.

• Custom-Molded Return Hose: The return hose is crafted from a dedicated molded silicone material, designed to fit perfectly within the engine bay, providing a clean and professional installation that complements the overall aesthetic of your vehicle.
