Curious about welding your wastegate directly to the turbine housing? Check out how one of our clients tackled the job!

Welding an external wastegate (WG) directly to the turbine housing offers several benefits, particularly for performance enthusiasts and those looking to optimize their turbocharged engine setups. Here are some of the key advantages:

1. Improved Boost Control: Directly welding the wastegate to the turbine housing can lead to more precise and responsive boost control. This setup minimizes the distance exhaust gases need to travel before being vented, allowing for quicker adjustments to the turbo’s boost levels.

2. Enhanced Turbo Response: By improving the efficiency of exhaust gas flow through the wastegate, you can reduce turbo lag. This results in a quicker spool-up time, meaning the turbo reaches its effective boost range faster, enhancing overall acceleration and performance.

3. Reduced Backpressure: This configuration can help reduce backpressure in the exhaust system. Lower backpressure means the turbocharger can operate more efficiently, potentially improving engine performance and reducing the risk of turbo-related wear over time.

4. Simplified Plumbing: Welding the wastegate directly to the turbine housing simplifies the turbo system’s plumbing. This can make the installation cleaner and reduce the potential for leaks or failures at connection points.

5. Customization and Space Management: For vehicles with limited space or for those seeking a custom turbo setup, welding the wastegate directly to the turbine housing offers greater flexibility in component placement. This can be particularly beneficial in custom builds or when retrofitting larger turbochargers into compact engine bays.

6. Potential Cost Savings: While not always the case, this approach can sometimes reduce the need for additional piping, flanges, and fittings, potentially lowering the overall cost of the turbo system setup.

******It’s important to note that while there are benefits, the decision to weld an external wastegate directly to the turbine housing should be made with consideration of the specific engine and turbo setup. It’s often recommended to consult with a professional or someone experienced in turbocharger installations to ensure that this modification is suitable and will achieve the desired performance improvements without compromising reliability.
