I bolting the turbo and move it to one side. Place a wad of cloth or paper towel deep down inside the collector behind where you drill the port for the thermocouple. 
You will need a cobalt drill bit and tap, both of which I have, and drill slowly and straight. 
The swarf will mostly fall outside but the push thru will drop a small amount inside which the wad is there to stop. 
Once drilled and tapped, vacuum out all the swarf then pull out the wad and bolt everything back together. 
Best gauges will cost a bit more and a stepper driven gauge is best for the response time. don't cheap out on one, it's really not worth it. 
I will email you a link for the Prosport gauges I got.
