That's not so much a turbo characteristic rather than an engine\calibration issue...
GT series turbos from 15-25 frame use vastly the same bearings... Any GT series turbo is unreliable if badly mapped or tuned even from the factory... Look at the BMW GT2256v and GT2360v, all in massively High demand, always going wrong, nothing to do with the turbo... It's more the fact the engine is badly designed and likes to drop chunks of swirl flap into the exhaust... Unsurprisingly writing off the turbo...
If cared for the GT series are reliable, hardy turbos, however they are susceptible to abuse and as such will fail if pushed... They will seem like they love 35psi of boost for 30 seconds and make that pressure, then suddenly shit themselves... All because someone got carried away with the boost controller... A T2 or TD04 will just turn into a hairdryer and become so inefficient they just carry on making the shit performance they always did!!
