Wastegates

A wastegate is essential for regulating boost pressure in turbocharged engines, diverting exhaust flow away from the turbine to prevent overboost. Our collection includes both internal and external wastegates from leading manufacturers, offering solutions for everything from mild street setups to all-out race builds.

  • Internal wastegates – Integrated into the turbocharger housing and actuated by a rod-style actuator. Simple and compact, ideal for OEM-style replacements or moderate boost levels.
  • External wastegates – Mounted on the exhaust manifold or up-pipe, with a separate dump tube. Provide superior boost control, faster spool, and higher flow capacity for high-performance applications.
  • Sizing and spring options – Choose valve diameter (common sizes like 38mm or 44mm) based on horsepower targets, and select spring pressure to set minimum boost without an electronic controller.

When selecting a wastegate, consider your target boost level, turbo size, and manifold design. A properly sized wastegate stabilizes boost, reduces lag, and protects the engine from excessive pressure. Browse our selection below to find the right fit for your build.
