Have some turbo questions....
Clearly my engine is not running at its potential, i haven’t run it hard because there is no heater so the windows are always foggy and there is no power steering.

Has great power till about 21 or 2200 rpm, makes about 17lbs of boost in that range and before. Maybe it makes more boost and more power at higher rpm, I don’t know because I’ve only driven it on side streets and the foggy window provlem.

I looked in the cold side of the turbo and the blades are full of nicks, the outer edge appears to be worn, it’s dirty and there is some play side to side. I haven’t looked at the hot side yet.

Should I rebuild this turbo with a new shaft and wheels?
Is the core usually rebuildable?
Should I buy a new center section already assembled?
Or is the condition Normal for used and should I just run it like it is?

Another thing, how hard is it to remove the injectors and what does it cost for new seals etc, if I do that?
I have the $900 OTC diesel injector tester, I was considering pulling the injectors to check the condition while I have the engine out. Does anyone know if the Cummins injector will screw into he OTC tester without an adapter? I only used it once on some injectors from a sailboat, unsure of what engine was in the sailboat,
