Before reinstalling the turbo housing, drill and tap a hole in the rear outlet of the exhaust manifold (arrow). Stuff a rag in the exhaust port before drilling to catch the metal particles, and thoroughly clean the port with a vacuum to ensure these particles don't damage the rest of the system. This hole will be the location for the pyrometer sending unit, which is included with the PowerPack kit.
