The damage on that compressor looks like static damage - rough handling while it was disassembled.
When you tear one up @ 60,000 rpm all of the blades eat it.
A cast compressor wheel is just fine. Millions of miles have been covered with cast wheels.
Atomization? LOL. That is the job of the compressor. On a draw through any carb works great. I always had great numbers from Quadrajet carbs. We used them because they were OEM on the GM vehicles, but I ran the Q-Jet on the dyno for everything. Easy to run the secondaries really rich. Once the fuel goes through that wheel @ 60k, it is atomized.
Should run good if you clean up the turbine discharge pipe & overhaul the turbocharger. If you have a decent 650 to 750 cfm carb of some type that will be fine.
With a target of 500 horsepower that would mean about 12psi of boost & 48 lbs per minute of airflow. That assumes an A/F ratio of 11.5:1, BSFC .5 & a .85 VE You will see a discharge temp of around 200f on a 100f day.
