This is interesting :-) A UK turbo firm (Turbo Technics) has *apparently* 
been making a batch of rebuilt Jap Supra turbos,as there are now enough of 
them in the UK to warrant this move.I was *told* that they had tooled up 
to grind the replacement shafts in steel,which led me to believe that the 
ceramic OE turbos used a ceramic *shaft*.All this is hearsay,but it made 
me try and research ceramic turbo technology on the net,with little 
result. Are you saying the *shafts* are always made of steel?

Thanks for the reply.
