Boost Response & Backpressure VS Turbine Dia and Housing AR

Guys got a bit of query regarding turbine selection for a turbo, i will use something similar to what i am looking at at the moment for my combo, 355ci V8 with a 80mm Comp Wheel T4 Rear S400 Borg Warner.
What difference in boost response and pre turbine back pressure would there between the following two turbine combos.
92mm Turbine Wheel in a 1.10 T4 Housing Vs a 87mm Turbine Wheel in a 1.25 T4 Housing ?
What i am interested in, does the housing AR effect boost response and or back pressure more or less than the turbine wheel size ?
