Question about Turbo Sizing

Are the values given for the compressor and turbine sizes the Inducer or the exducer values? I am trying to recreate the measurements of a turbo I want to run on my current engine but I am unsure of which the given values are. If they are exducer values they are waaay too small for most performance applications.

The numbers are the outer diameter of the compressor and turbine wheels. The turbos will get a redesign soon-ish.
