I have a blown T25 and I do not want to reuse the compressor wheel because it was left to scrape the housing...
I would LOVE to upgrade to an S15 GT28R but unfortunately, at this time, I do not have the cash to spend on the necessary upgrades to support that (injectors, tune, etc.) on top of the cash I have already poured in recently.

An option that looks enticing, but I am not finding too much definitive information on is:
Rebuilding my stock S13 T25 with a G-POP kit.
Buying a GT2560R 0.60 A/R compressor housing and wheel and adding it onto the stock T25 being as the hot side is the same anyways.
(I am aware of balancing issues and blah blah. Do not really care as it will not be on the car for too long..)

I would rather do this then source a used T28. 1) It gives me the experience of rebuilding a turbo. And 2) I have a nice rebuilt turbo that will give my S13 a small kick in the ass..

Will this work just fine? Will I need a tune (don't really think so. Yeah, it'd be nice/ great but is ot necessary? Only ~30hp increase)
