Please explain how a GT turbo is superior.. and please don't come out with any 'faster spool' crap..

Tried and tested?? Compared to what..?
The GT32 has a wider range, slightly larger compressor side than the step down TO4B based comp wheel in the T34. The turbine wheel is slightly larger, and has two options of turbine a/r, 0.69 or .78, and the output flange flange can be opened up from 2.5" to 2.8" if nesseccary. It has a standard T3 manifold flange.
Then there is the off the shelf option of having the GT 76mm compressor wheel fitted to the same housing, with potential for 520bhp and all cheaper brand new than the cost you see most T34's second hand..
