From what I understand Back Pressure is the #1 enemy of becoming more efficient on any given turbo setup. I was only considering the turbine size.. I'm sure the 4-5/8" V-band would considerably reduce Back Pressure on the PT7675 GT42 style.
Maybe the PT7685 GT42 style would be more appropriate on a 6.0 liter? ...And the PT7675 GT42 style on a 5.3?
