According to some literature on the internet, one of the differences between the Jap spec JZA80 twin turbo (MK IV) and the UK version is that the former has ceramic turbine rotors and the latter steel, but no explanation of reasons is given.
At a guess steel sounds stronger, and ceramic perhaps better for high temperatures and avoiding corrosion, but I'm curious......?

Ceramic turbine rotors weigh less than steel ones, so they spin up faster, thus reducing turbo lag. A friend of mine has a Skyline GTR34, which has two ceramic turbos and no lag whatsoever....

Andy, thanks!
Certainly I do not have much lag; the car is perhaps a little (relatively!) sluggish for a second or so from a dead stand but then it is automatic - that is, no clutch to drop in to jackrabbit, to the detriment of the works!
Cheers, Tomo
