MIG will work, pending the skill level. With a MIG process, you have a chance of some spatter inside the runners and if any of it comes loose, you may very well take the turbo out. TIG may be a better option if available as the material is very thin. Use SS wire and be sure to "gusset" the connection.

Take your time and reduce the heat as the flange may warp.
