As far as i know there is not a T6 1.0 A/R housing. There is a T6 1.10 A/R housing for the 96x88 wheel.
Wheel sizes as follows:
96x88
87x80
83x75
Should be one of those. Can you measure the turbine wheel, that would be a better way to tell. Turbine wheel size effects the piston ring size on turbine side.
I bought it from. Guy on powerstroke nation that bought it from another Guy on powerstroke nation, when I asked the original owner of it he said it was a s475/83 with a t6 flange I'm assuming that means its a 75mm compressor and a 83mm turbine .
I can measure it later if I need to? Do I just measure the outside of the turbine wheel?
