Secondly, what do you mean in bold?

Lastly, yes, lay a bead where the flapper shaft exits the turbine housing while the flapper is closed. Then just make a WG feed port in the manifold or turbine housing.

The... ATS-V and CTS-V turbos have the same design. The turbos part numbers are interchangeable. The bolt pattern on these does not match the bolt pattern on the LGX motor although they are very close.

Vacum operated WG stay open until you start the motor and are prone to failing. In fact these rattle like a mofo. Here is a link to better describe the differences . I want my WG to open when boost hits.
