CX-7 with a rebuilt engine, good idea?

I’ll definitely do that, thanks for the advice. I have a mechanic I trust in a local garage, would he have the equipement for that test or do I need to go to mazda for that?
Also is there any way to find out the condition of the turbo? Cause I hear it’s about 5k to have it changed if it lets go.
I’ve already asked the guy to get an inspection at mazda, is there anything else I should ask him to do?
