With these 2 turbos having the same size exhaust wheels/housings, am i correct to assume spooling would be the same, just the 83 inducer would just move more air?

An 83 mm wheel will have more mass than the 75 mm wheel will . It will spool slower now in a compound setup with the proper fueling setup it probably won't really be noticed.

The 83 will also likely have a larger exducer supporting what badbowtie stated.
