35-38mm WasteGate Flange

The 35-38mm WasteGate Flange is a precision engineered component designed for turbocharged and supercharged engine builders seeking reliable wastegate installation. This flange serves as the critical mounting interface between your turbocharger's exhaust housing and external wastegate actuator, making it essential for boost control systems on high-performance vehicles. Whether you're tuning a street car, building a track engine, or restoring a modified platform, a quality wastegate flange ensures proper exhaust gas bypass and consistent boost regulation.

Constructed from durable stainless steel and measuring 0.375 inches thick, this flange provides robust support for high-temperature exhaust environments while resisting thermal stress and corrosion. The 8mm x 1.25 female thread design accommodates standard wastegate actuator rod connections, allowing seamless integration with popular wastegate models including Tial, Deltagate, Evolution, and Turbosmart 35-38mm units. The stainless material finish maintains structural integrity under sustained heat cycles, critical for applications running elevated boost pressures or extended track sessions.

This wastegate flange benefits engine builders, turbo shops, and performance enthusiasts installing external wastegate systems on 35-38mm turbine housings. Compatible with multiple wastegate brands, it provides a standardized mounting solution that simplifies fabrication and reduces custom welding requirements. Proper wastegate flange installation directly impacts boost control response, preventing overboost conditions and protecting engine internals—making this component a non-negotiable element of any serious forced-induction build.
