What are the non-genuine N55 CHRAs and compressor housings like?

Eg. Dinan, VTT Stg1, Kinugawa and a handful more.

Are they a copy of the genuine BorgWarner item with the same style twin seals, bearing dimensions etc. or are they an adapted MHI-style TD05 or something?

This is not a debate on performance or differences (if any) between the wheels. This is SOLELY a question about the bearings, seals and compressor housings.
