I don't know guys, but on both my K27 7006 and 7200 turbos (the 7200 I just put new seals and bushings in), and my old 3LDZ I can say that these things spin freely but won't keep spinning on the bench top for any length of time after giving them a good finger tweak. Too much clearence between the shaft and the bushings without the oil pressure and resultant film to float the shaft off the bushing = static friction drag. That's benchtop, but it doesn't mean the turbo is not "spinning freely" when in the car doing it's thing.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
