Message :::if you know that my turbo is dead, skip this part:::
For anyone who doesn't know what's going on with my Z, I swapped
over the GT2530's, boosted twice (~17psi), and it wouldn't boost over
~2psi after that (click my profile and see posts in the general forum to
see my previous post for more details). I got the engine out last
weekend, took the downpipes and intake piping off to inspect the
turbos... here's the stuff I don't recall.

:::new information:::
The drivers side turbo is blown, no doubt in my mind. Too much shaft
play, and the bearings are loud, but it still spins relatively freely. Would
one blown turbo cause a condition where it would only get 2psi?
Obviously, boost pressure is collectively measured at the intake plenum,
but I don't remember the symptoms when I had to replace a single dead
turbo last time.

About a year ago, I replaced the passenger side turbo due to the exact
same thing. However, as stated, I don't remember if this caused low
boost or if it still boosted freely (I know it scraped the inner housings, I
could hear that).

:::cliff notes:::
So the question is, can a single blown turbo result in less than 2psi of
boost even if the other turbo is still good?

I just want to know if I should keep searching for a reason that it's
underboosting or if the turbo is it. TIA.
