turbos are like tv's or any other consumer product. each individual company does not make their own parts. its far too expensive.
there are only a few parent companies making the CHRA's & turbines and then companies assemble the bits and pieces to form a product. metal is metal all over the world so the housings are easy to make anywhere by anyone. its simple casting. and with 5axis milling becoming soo abundant... anyone can make a make a billet compressor wheel. there are home desktop mills able to carve compresor wheels availble for less than a few thousand dollars.
so just like sony, panasonic, magnasonic, samsung, sorny, magnetbox, etc... they all have the same guts inside. heck even your apple iPhone isnt made by apple. this is just how consumerism works. even a big companies like Blouch use Garret CHRA's and turbines...
the problem with cheap chinese turbos in this case is the finishing. while the metal and castings are the same everywhere, there could be bits of casting flashing left on the inside ready to destroy your turbo. making a chinese turbo good is a simple process of disassembling the turbo, cleaning up any poor manufacturing. while it is apart you could even change a wheel or two if you feel like it.
