v300

I had a custom T04S w/ .70 A/R built by XS engineering. Don't get me wrong... it was an awesome snail for the street but I would like a bit more on the upper end... without killing my tranny (but that is a good thing to worry about). Has anybody ever heard of salvaging parts of the T04S and fitting it with a Garrett T62-1? Supposedly I will retain the turbine side but the compressor housing will get replaced with a larger one. I will still be using .70 A/R... what do you guys think?
