Need opinion on Delta Air Compressor model 66-240 and Air-Tools

I bought a Delta Machines

Here are the specs from the manual

Model: 66-240 HorsePower: 2.5 Max, 2.0 Operating Voltage/Herz/Phase: 115V / 60Hz / 1 Min Branch Circuit: 15 Amp Air Tank: 4.5 Gallons CFM @ 90 PSIG: 5.2

It's an oil-lubed motor.

Anyone know if the motor cylinder wall is Cast Iron?

What size and CFM rated Impact Wrench should I get that would allow for intermittent use to change tires on my car?
