Default I couldn't get my calipers to fit in far enough to measure past the machined step, but here goes

Inlet id ~ 1.9", machined out to 1.975" to accept intake pipe.
outlet id ~ 1.435" machined out to 1.748" to accept compressor hsg.

I ended up sticking a spoon in the inlets, marking the spoon where it stopped at the machined lip and measured that distance across the spoon.
