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.

LONG story short it is in but the waste gate is not returning to the full closed position. The actuator rod is to long, the steel of the plate to move the position of the actuator is too thin and keeps flexing. So while I had it in I bent the bracket that the actuator sits on (or so I thought), during that time I got incredible boost (compared to the 26) at about 50% of the Turbos max output according to my boost gauge. That output @ 50% was about 10-11 psi. Spool up was very smooth and quick, torque steer is off the map though (need an LSD, Be calling you soon Culp). Since then though the steel of the bracket and or it's holding plate has had a chance to relax again, sooooooooooooo... ...Tomorrow is another day. Tomorrow I will be either re-bending the rod to the specifications in how to, altering the bracket to allow for the rod length, or cutting and welding the rod to the proper length of I believe it is 7 3/8.

I have pictures and such but I refuse to post them until I am finished (it's bad luck IMO). I should be completely finished with the gremlins tomorrow.
