I gave it a real good hit with both WD40 and freeze-n-release. (give the bolt a good 15 second hit of freeze-n-release before you hit it). Used some decent socket on it, breaker bar, lent some pressure on it till it cracked. Few pulled the studs from the turbo, but nothing broke.
Expect the rear heat shielding to cut you up a bit though, right PITA...
