I just purchased a used T3 from a nissan 300zx off of ebay. How would I go about testing the condition of the turbo? The turbo looks fine, should i test anything else on it? Thanks for any input.

 

is there any play in the shaft? that's about the only test.

 

no shaft play.
How freely should the wheel spin tho?

 

if it's lubed, it should spin freely.

 

hrmm... Mine spins surely. But not very very freely. There is some friction. Is that bad?

 

does the friction feel rough or do you mean it just doesn't keep on spinnnig freely for a while? Try squirting some oil through it, and spin it. If there's oil coming out teh wheels then your turbo is gone... needs a rebuild.

 

well, i haven't put the turbo in my car yet. Still sittin in a box in my garage. I was just playing around with it earlier. But yeah, when i try to spin it, theres just a little friction. BTW, where do i exactly squirt the oil?
