Wastegates – External & Internal Turbo Boost Control Valves

Wastegates – Essential Components for Turbo Boost Control

Wastegates are critical for regulating turbocharger boost pressure and ensuring your engine operates safely and efficiently. By controlling the flow of exhaust gases to the turbo, they prevent over-boosting, maintain stable pressure, and protect your engine from damage. Whether you need an external wastegate for a custom turbo kit or an internal wastegate actuator for an OEM-style setup, we have the right solution for your build.

Why Upgrading Your Wastegate Matters

In high-performance and motorsport applications, factory-installed wastegates are often insufficient for handling increased boost levels. Upgrading to a precision-engineered performance wastegate delivers multiple benefits:

• Accurate boost control for consistent turbo performance.
• Prevents overboosting, protecting your engine and turbocharger.
• Motorsport-ready durability designed to withstand extreme exhaust temperatures and pressures.
• Customizable setups with interchangeable springs and adjustable actuators.

Types of Wastegates

• External Wastegates – Mounted on the exhaust manifold or turbo manifold, designed for precise control in high-boost setups.
• Internal Wastegates – Integrated into the turbo housing, ideal for OEM-style or bolt-on turbo upgrades.
• Wastegate Actuators – Control internal wastegate operation, available in adjustable and fixed-pressure variants.
• Water-Cooled Wastegates – Designed for extreme racing conditions where additional cooling is required.

Applications

• Custom turbocharger builds
• Big turbo upgrades
• Street performance tuning
• Motorsport: drag racing, drift, time attack, and endurance builds

Choosing the Right Wastegate Size

The correct wastegate size depends on your engine, turbo, and boost targets:

• 38mm Wastegates – Ideal for small to medium turbo setups.
• 44mm / 45mm Wastegates – A versatile size for most performance builds.
• 50mm+ Wastegates – Recommended for large turbochargers and extreme boost applications.

Installation Tips

For maximum efficiency and reliability:

• Use high-quality turbo gaskets and mounting flanges for a leak-free seal.
• Ensure wastegate placement allows optimal exhaust gas flow.
• Match the wastegate spring rating to your target boost pressure.
• For high-power builds, consider pairing with an electronic boost controller for even finer control.
