Oil only? Or water cooling too...
I bought a godspeed chinacharger...
and I bought a Tial 38mm MV-S water cooled external wastegate.
I want to keep my street car simple...so should I:
A: Use the water cooling on only my wastegate?
2: Use the water cooling on both my turbo and my wastegate?
D: Run strictly oil cooling to just my turbo, and say "cooling? We don't need to stinking cooling!" on the wastegate?

What color wastegate did you get? If you do not run water to it the chances are very high that it changes colors from the heat very quickly. I would honestly just run water to the turbo and waste gate. It is only 2 extra lines and not that hard to do.

That's what I thought too, but also because the wastegate is higher than the turbo. I know the water line is pressurized, but it's better in my mind to flow with gravity, not against.

You actually want to flow against gravity with water cooling lines. Garrett put out some tech data a few years ago about this topic. Apparently they got the best results by having the center housing slightly off axis by like 10-15* or something. Then feed the water into the lower port and out the higher port. Since heat rises, it helps the water get the heat away from the turbo more effectively. This is of course an ideal scenario, in real life, on a street car, I seriously doubt it matters.

Comes off the thermostat tube (WP outlet). The lower one ("mixing manifold") is the water pump inlet.
Bottom to top for flow when adding heat. Look up "convection." Way back when, some cars skipped the water pump and all water flow was done this way (bottom to top in the engine, top to bottom in the radiator).
