Note: The optimum mounting and placement of your new PW39 wastegate will be determined by your manifold

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 PW39 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.

clamps. Route all vacuum hoses away from high heat sources such as the turbine housing and exhaust
manifold.

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.
