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.

In my opinion to best use a CT26/T04e-46 hybrid turbo you need a 3s-gte stroked to 2.2 thats still capable of revving to 7000.

In that case a ct20b would be no good since it would plateau alot earlier than 6000 and drop off by 7000, but the ct26 rear housing since it contains a larger exhaust wheel would help solve that.

But then you could make a CT26 rear housing/CT20b front housing hybrid which could be even better than machining a ct26 for a t04e-46 wheel since the ct20b already has a 48mm.

Or possibly even a CT20b rear housing and CT26/T04e-46 front housing for supercharger like performance on a 2L
