ct26 turbine wheels, JDM ceramic versus USDM steel, differences? Are they noticeable or negligible? Options

[Darkchylde]

Soooooooo, I have had to send my 26 out to be rebuilt and in the process have found that the turbine wheels need to be changed. The shop that has the turbo says that they can't get the JDM ceramic wheels so they will have to use steel ones.

1) how will this affect my spool time/ Lag? (new to forced induction, understand the basics but am still a little fuzzy on the intricacies)

2) anyone know where to get the ceramic wheels?

3) any one have a JDM importers # or a 26 or 20b they can spare?

Thanks for your input and assistance all.

i vividly remember the limited days i had with a ct20b, i'd go around a corner from really low revs and if i had my foot anywhere past half way, once the tacho needle moved past 2800 the engine would just suddenly go mental and the rear wheels would slide sideways, but it was really nice to drive too in low revs, totally effortless.

then this ct26 (jdm ceramic)/t04e-46 i had after that, everything was smooth but gutless down low, there was never enough boost to even try to go fast until 3500, and then at 4000 it made a very smooth linear transition into power, didnt make good power until 5000 and then between 5000 and 7000 it totally haulled ass, but its hard to compare the top end because the ct20b plateaus at 6000, but its very quick anyways at those revs
