Managed to remove the compressor housing. There was some red sealant between the plate and the housing. I wonder if I should use sealant at assembly as well?
Despite all my efforts turbo housing was stuck and I really began to worry that even if I get it moving I'll damage the blades. Luckily I remembered that I have cheap android/pc borescope kit somewhere. Finally I got a good use for it.
Despite some marks on blades I believe this turbo will have some track time
