Well first off I took the bracket out with the turbo so I could take care of this bolt on the bench. Ultimately after about a week of PB blasting it took a 7/16" Allen socket, 3/8 to 1/2" converter, a 1/2" drive 2' long breaker bar, consistent tapping from a hammer to keep all that in the head of the bolt, a pipe wrench on the outside of the bolt and two men combined 350+lbs to break the sucker off of there. That was our last ditch effort before trying to torch the thing off and salvage the bracket. Honestly I'm surprised we didn't crack the nut from its welds when it broke loose.
