KKK16 has integrated exhaust collector in to the turbine housing... So it's pretty obvious I cannot drill in it... It's too small and too risky that could result with buying another turbine...
I have bigger EGT (thick one) from VEMS shop...
The picture isn't so clear...

I'd put the hole in at the point where the wastegate T's off from the housing. After pulling the turbo out of the turbine housing of course.
Can you mark it on the picture?
