Would anyone like to offer an opinion on whether the pictures of my turbo show that it has been ungraded to metal turbines or not.

I have tried the magnet approach. I found that neither set of fins seemed to be metal, or at least not a magnetic metal. I thought I had read somewhere that the metal fins are an alloy or such like and therefore the magnet approach isn't going to work.

Thanks for the suggestion though.

They are ceramic they have the standard turbine multi hex nut.

They should be steel wheels with the Tri nut. Not all metal wheels are magnetic

The "steel" wheel turbos are not magnetic.

To the best of my knowledge they are actually some form of iconel alloy, so the magnet doesnt work.

It looks like the nut found on the standard shaft of the ceramic turbines, I dont know why it would have been reused so my guess would be they are ceramic (but then again, theres a 50% chance they could be 'steel').

Get them checked out by a turbo specialist, its the only way you will be 100% sure. One thing I can tell you is the previous owner liked running octane booster :)
