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 don't know, Someone will try and correct me here but I was running 17psi on the ct26/t04e and it was like the ct20b at 14psi in the top end, it was like not having a turbo at all in the low end.

It barely felt like I had 230hp at the engine

THE CT27 isn't the ct26 u keep saying ct26 the one thing the ct27 has is the ct26 hosing that its when your celica can beat one of atsracing mr2 u can talk all the crap in the world about a ct27 but i dont think that will ever happen i dont even think they have a mr2 up there runnin anything under 450 rwhp go check out these links on youtube this is matt's car from atsracing http://youtu.be/0Imf2NiB1xI.........and thats why u blow up turbos not because there crap because the ct26 is a good turbo but because u ride around on 17psi u are killing that turbo it is a stock turbo not after market it wasn't made to be beat up like that and if your car was stock with no upgrades you are making the turbo do all of the work

when you own a gt4 or a 3s-gte car with the weight of a gt4 you'll reconsider the ct26. ct26 only feels good to you because even 200hp in a fwd na celica makes it go fast.

the ct26 blew its oil seals long before i boosted it to 17. 17psi is fine on a t04e rebuild, thats how the ats turbo makes its power you think they mess around with stock boost? they wont barely see 190hp at the wheels buddy let alone 450 or whatever you claim.

the ct20b ceramic turbine shattered at stock boost - 13psi.

i already posted what i know, 53mm t04e wheel is the biggest u should get in a ct26, even look on the ATS website they say the same thing themselves, their CT27 is exactly the same as the turbo I had, unless they also do something with the exhaust wheel but as i already pointed out, the ct26 exhaust wheel is 2mm oversized as it is, they cant go with a smaller wheel they can only replace it with a steel wheel which provides better durability, mine remained ceramic.
