I'm not really sure if that will work or not, but the real question is is your t25 in good enough shape to justify spending $250 on it. No shaft play, good seals, etc.
Really by swapping a different housing on a t25 doesnt turn it into a t28. T25s use journal bushings while t28 are ball bearing. And supposing that you did swap to a higher flowing turbine housing you would still have the weak t25 compressor wheel. You will be limited to a max boost pressure of around 19lbs. Anything higher than that and you will most likely see the compressor wheel explode, which I would love to see but Im sure you wouldnt.
Just save your money and buy a real T28 or a gt2871r.
