Z32 is the same size as the 33 and the filter boltholes are in the exact same place. Q45 is 10mm bigger. Can't recall what each max out at, but the Q45 is used for bigger power figures where the Z32 would be maxed.
You can either get a custom intake pipe made, or easiest solution is to use a 80>70mm reducer silicon pipe. You'll need to get a filter to fit the Q45 afm too.
