So the turbo i swapped over has quickly (like within 30 miles) developed a loud siren noise, much louder than the one I had one before, and it'll do it when not under load, ie giving it a rev in neutral.
Pulls ok, haven't noticed any blue smoke.
Likely to be completely knackered? Or live with it until I source another and build up the energy to swap a turbo ...
Its running 25ish psi btw

Pipe may have slipped of the inlet? I'd suggest get under, give it a few rev's and find where the sound is coming from?

its holding boost ok though, and the noise goes up and down with the revs, not the boost.
I.e. if you let off the boost drops almost instantly, but the siren sound winds down

my "siren" goes after like 4/5 psi, then comes back on when i shift down etc...

question is though, have i knackered by asking too much boost of it in such a small amount of time, or was it knackered anywho and i've brought it to the forefront.
didn't start off noisy, but hasn't taken long to sound fecked.
looking at rover 1.8t turbos, but they're kinda hard to get hold of tbh, and the one off the landrover has a ridiculous exhaust angle thing going on, can't see it ever going on an xud easily

I doubt you have broken it in such a short time, a good one will hold 30psi for a while. do you know any history of it? Like has it sat around in a garage for a while?
What turbo is on the rover?

Its been sat around for a while in a garage, can't remember what it was off ...
rover has the gt2052s i think, but i've been asking around for a while now and they either don't come up or are snapped up real quick, on the rover only came on the zt and 75's models which are probably now dwindling in numbers... need to find out what else has them on as standard, maybe some saab 93's?

If it sounds like a police siren then that points towards it having a bent blade on the compressor normally 
Unless there is a lot of play in the shaft and its catching the housing maybe?
