Thanks Jame , as I suspected.
I have a T34 -48 turbonectics Comp -minor 2.122/major 3 inch-Turbine-minor 2.126/major-2.555 .
This is slightly bigger than your Garret T34, I would imagine that having a .48 turbine housing =small housing?
Why did you recommend a -31? or were the right question's not asked?
My Best.
