The way i normally tell if a turbo is good/bad is i try to move the turbine blades back and forth to see if there is play. (some is ok). Next i spin the turbine wheel to see if it spins freely, if it does then its usually in pretty good condition, otherwise it might need a rebuild.
Hope this helps !
