Dumb turbo form factor question
 

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!
