that's because you posted it in the wrong section.

that's a common thing. T28 wheels with T25 housings. I really don't see the point in doing such a thing, getting a straight T28 is better, but that's what some people do.

Now as for your turbo, looks to me like you have a T25. However I need to know the housing sizes and stuff...the turbine housing size is inside the turbine inlet.

Mike, I could be wrong, but I remember reading somewhere that a T28 is just a name for a T25/T3 hybrid turbo (probably T25 housing with T3 wheels, or T25 turbine with T3 compressor, I don't remember to be honest). It may have changed, but I remember reading that.
