why not rebuild the t25?
rebuildkit-100
t3/t25 compressor hosuign adapter-60
60trim compressor wheel-40 or less used
t3 60 trim compressor housing-20-60

so for under 300 you would have a custom t28 with sleeve bearings so you could rebuild it whenever you want. sound slike a sweet deal to me.

(edit) woops! didnt see you got it fixed, oh well
