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.

ct26 is crap nomatter what they do with it.

for starters the turbine exducer is 52mm in a ct26, its only 50mm in a ct20b (smaller is better here for spoolup)

the standard ct20b compressor inducer is 48mm, the largest one they can fit in the ct26 is a 46mm t04e wheel (up from the standard 42mm)

compared to a ct20b the best you can achieve with a ct26 is same max hp at a higher boost level, with an extra 1000rpm of low boost threshhold and laggy throttle response
