Did some Googling and couldn't find an answer, so if you could. I'm finally looking to start dropping coin on parts and I'm curious if say, a gt2252, gt2554 and gt2560 are interchangeable. From pictures it appears that the exhaust turbine or flange is shorter or longer depending on the size of the turbine, but without dimensions I can't be certain. thanks!
