You seem to have gotten the cart in front of the horse. Modification components should be carefully chosen to complement the build you desire, if not you may be disappointed.
The GT35 is a big turbo and big turbos trade top end for lag. The headers will help reduce the lag. Garrett's are not designed for 930's, take Dave's advice and call Chris as he has the parts you will need to adapt it to fit/work.
Leaving off the trubo bracket will stress out the headers and everything else holding this 30 pound lump bouncing in the air. The OEM bracket also locates the turbo properly so that everything else attached to the turbo also fits. If everything will be custom then that no longer matters.
Have the WUR rebuilt and made adjustable before you add the mods. The fuel curve needs to support and complement the new power curve.
TiAL wasegates are artwork. If your OEM WG is original and never rebuilt I would replace it. If it has been rebuilt and works well then add the 1bar spring for a $400 savings. I don't like boost controllers personally, especially with CIS. There is no reason to adjust boost up or down, that is what your right foot is for. Just leave it up and tune the engine to safely run it that way. CIS is not a dynamic system, you adjust it for a specific boost level, it will not compensate for "banzai runs".
965's are great cars that respond well to mods. Take your time with it and the end result will be an enjoyable car that runs smooth as stock and goes like stink!
