no it is no a ceramic i did not know they even made them any more and i have been playing with turbos for a long time. no the 61 is a gn turbo from the early mid 90s when they came out with good ones for gns. the 74 i bought when my 72 was bad to replace the 72. i bought the 61 to stick on the ty when the 72 was bad to find out if it was the turbo smoking and not the motor. i had done many "smoke" fixes like intake gaskets and such and it was still smoking so i picked up the 61 from a friend and tried that and the smoke went away. that is the only miles i have on it is is from sitting in my garage with no down pipe on to make sure it did not smoke. the 74 i had on my last motor in the ty when i melted 2 pistons i took it off and went to a 57 and a smaller build. i want to try and get 500 to the wheels with a smaller build this time, see if maybe i can hold it together without so much flow going on. like stock heads, smaller turbo, stock manifolds, smaller ic. little to no play in both. but like i said they are as is i dont know if either are perfect inside and you can never know with any used turbo unless they are sent out and check out.
