So I feel like I'm spooling slow - GT2860RS

Replace/weld up the pipe, get that coolant line fastened to something, and enjoy.
Here's the bad news: In order to make boost with that large of a leak, you've probably been running the turbo way past its max RPM. The turbo may start passing a little oil, and it may have a little more shaft play than normal. Keep an eye out for these things.
Stupid. Best Fix would be to Just put the hole in the nice groove and jbweld it in place. That's where it wants to go so let it go there.
