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.

dude u have no idea what you are talkin about they dont just switch out parts they redo the whole turbo what part dont u understand they dont use nothin from the ct26 but the hosing the ct20b and the ct27 are all most the the same the ct27 hp is maxed out stock with no upgraded wasted gate at 350hp thats just bolting it on to your stock set up with no up graded internals and a stock wasted gate now think if u have a 50mm wasted gate upgrade the internals the down pipe has nothin to do with nothing but use a brek down pipe upgrade your injectors u will see 700hp i dont know how yall do it over there but we dont just ride turbos we redo the whole engine like i said u are making the turbo do all the work if u have stock internals and I DONT HAVE A CT26 i have a CT20B caldina 3sgte st215 the whole engine not just the turbo around here we pay to play ill go to ats right now and buy one of there 2.2 stroker kits and it will be faster than your gt4 i go to ats alot i know what there cars can do ive seen them in person and if that turbo sucks so much i guess not bad because they have cars out the zoo sittin out there shop they couldn't even get me in last week to do my exhaust oh and by the way they use a 46 trim wheel not a 50 whatever u keep tryin to say OH and the ct20b shattered at 13 psi thats bull crap because my ct20b is runnin 15 psi all day and i have someone on here that can back me up with that....ask easternpiro1 hes runnin the same engine i am

what are you on about?

yes the t04e wheel comes with 2 options a 46 trim and a 50 trim, 50 trim is the one i had, it's 46mm inducer, the compressor housing is machined to accept the larger wheel. the stock ct26 compressor wheel only has a 42mm inducer. for comparison the stock ct20b has a 48mm inducer, so both the 46 and the 50 trim upgrades flow less than a ct20b.

sound like you need to go here and learn what trim and inducer and exducer means before you run your mouth.

as taken from atsracing.net

Finally a 300rwhp CT26 upgrade. So different from other CT26 upgrades we had to call it the CT27. ATS Racing machines not only the compressor side of the turbocharger to fit a T04E compressor wheel, but also performs CNC operations on the exhaust housing that are dyno proven to increase flow.

I wasn't aware of of any machining to the exhaust side, but the turbine wheel has a 52mm exducer, it's already oversized, it's only 50mm in the ct20b.

and you make no sense about flowing 350hp into stock pistons and fuel, as for one even the upgraded t04e wheel is slightly smaller than the standard ct20b compressor, so it's flowing less air at the same boost, and two didn't you know the st205 has 540cc injectors and is mapped to 18psi? ofcourse you didn't.

and yeah the turbo does do most all of the work on a low compression turbo engine, go take your turbo off and go for a drive and you'll see.

also your logic fails, you have a st215 swap and run 15psi and haven't had a problem yet, i have a genuine st205 and somehow your swapped celica has something to do with the condition of my former oem turbo?
