The shift in sizes are one factor but on top of those that A/R is going to make for some slow spooling from what I know. Calculating turbo flow and efficiency aren't my thing though so a second and third opinion would be a good idea. The CT-26 A/R is about .49 though.... it the inducer and exducer were the same size as the CT-26's it would already be a lot slower spooling.... more power potential with the larger wheels, but with the time it's going to take to reach its potential will you be past redline?
