Here are the pics of the turbos.
There is absolutly nothing wrong with them, and were removed for new garrett ones to be installed.
The care has always been run with air filters on so, there is no damage to the compressor blades, just could do with a good clean.
These are the Ball bearing units. Im not too sure what model they came off, as they were picked up some time ago by a mechanic.
They did not blow any smoke what so ever, and were never over boosted. They were simply used to run in a new motor till they were to be replaced.
These units were never fitted to a skyline so there are no lines to include with it.... sorry
If you need any more info, happy to help.
Thanks
