PW46 Water-Cooled External Wastegate Installation Instructions:
- The PW46 wastegate is compatible with Tials 44MM wastegate weld flange, for a trouble free bolt on replacement.
- Be sure to install the valve seat into the body of the wastegate before final installation.
- Tighten the supplied bolts to 85-90 inch /lbs (9.6 – 10.2 Newton meters).
- In order to assure proper boost control, your PW46 water-cooled wastegate needs to be mounted at a smooth transitional angle with the exhaust flow. 90° mounting onto exhaust tubing is NOT recommended. Refer to diagrams below.
- Inlet and Outlet flanges are constructed of, 304 stainless steel and are compatible with most stainless steel and mild steel welding rod material.
- It is recommended to secure all vacuum and or boost control hoses securely with zip ties or cushioned clamps. Route all vacuum hoses away from high heat sources such as the turbine housing and exhaust manifold.
- Your PW46 wastegate includes two hose barb banjo assemblies and one pressure port cap. Allowing you to install the lower hose barb banjo assembly in one of two locations, depending on your wastegate mounting position.
- Allow for cool airflow around the top billet wastegate cover.
- Use caution when working on a hot engine. Wastegate and turbocharger components are EXTREMELY HOT and can cause severe burns.
- Wastegate outlet can be routed back into the exhaust system or vented to atmosphere. Note that venting to atmosphere only applies to OFF ROAD VEHICLES. Venting wastegate exhaust to atmosphere may be ILLEGAL and considered to be emissions related tampering under applicable laws, rules and regulations.
The PTE PW46 water-cooled external wastegate is designed to be a direct fit replacement for other units on the market and is compatible with most aftermarket manual or electronic boost controllers for ease of use.
As an added bonus, all 46mm Precision Turbo PW46 wastegates are warranted to be free from manufacturer's defect for a period of 12 months or 12,000 miles!

WARNING!
- Fitting a heavier wastegate actuator spring may cause a higher than expected increase in boost pressure.
- Use of a turbocharger speed sensor is a good idea if you plan to run very high boost levels
