I had a new Turbo installed... And made a discovery

[ynot]

Well in the next month or so I'll have some answers too these would it be tunable and work fine questions. My hybrid 561/551(off a volvo) turbo build is done, it's actually been sitting in my basement for the last month waiting to be installed.

If ya get a chance can you get the casing numbers of the exhaust side and the compressor side of the 551 there installing for ya??

Cause I'm not sure if something got lost in translation on the one they built for me cause the way I understood it they were gonna machine the 561 housings to fit the bigger wheels but from the looks of it they slapped the compressor housing off the 551 on it, which is noticably bigger then my current 561 and only machined the exhaust side cause it's got the same casting number on it as my current 561.
