With the way that the crack is running along the heat effected zone of the weld it will spread once you start to grind into it. That is the reason for drilling the hole so the crack does not run. Once the root and hot pass are ran you can do some overlay with mig if you want to build up wall thickness in that area. If you chose this route let me know and I will tell ya what mig wire you need.

Correct - InSane and Ryan.
Brains - the next thing I would try is the gussets and/or stitch welding on the cracking areas with the proper prep.
If I can ask, are you MIG or TIG welding it?

Yeah brains that is prob going to be your best fix. I am pretty sure that it was the welding wire they were using if the new welds are not breaking. Because there is no way in hell a weld cracks like that on the heat effected zone. Only way to be 100% sure is to get whats called a PMI test on the mat and the weld its self. That checks the property of metel there is IE nickel, chrome, zinc etc. and tell weather its 302,304,308 or 316

He has poured more money into that turbo from QMP trying to make it work correctly and never been successful. I am sure if he could go back in time he would change his decision to have bought the QMP turbo in the first place
