That's all I needed to know.
Upon further research, it's a T04b 57trim knockoff. It's actually a very solid "big shaft" design.
Downside? The wheel's diameter, from my experience, is ~.75mm too large/small, depending on the wheel used, which is very inconsistent. It should be a 1.0 a/r turbine and a .60 a/r compressor.

As of now there aren't any interchangeable turbine housings that i've found.
It should have a 2.07/2.36 inch turbine, which is quite funky.
