My GT2560 is the same, the triangular bolt sequence is rotated about 60 degrees over a standard turbo. My solution was to cut the pipe from turbo to intercooler, rotate bottom half and join back together with radiator pipe from a digger.Cheers.
I want to vomit everytime I see that compressor outlet pipe.
My uprated turbo has a 3 bolt outlet flange, but it's slightly offset to the standard holes.
