Tufy you are awesome. what about a stocker but getting it cryogenicly treated? a friend with a 600whp rsx had his STOCK tranny done and its holding the power fine. i know all transmissions are different but that seems like a good testament for cryogenics.

Hi itchy,

given that I'm in the same boat, could you please ask who and where makes this cryogenic treatment ?

Thank you

it was a local shop that did it for him here. but there are plenty of online cryo shops. i found that one but im sure theres more.

WTF are you guys doing to break these?!!!

I haven't heard of anyone breaking the trans from too much power.
Or the rear diff for that matter....

To answer your original question, there is only 1 stock trans available for the AWD Celica that has different gear ratios.
It's the homologation version found in the ST185s.
All the ST165s, all the ST205s, and the regular ST185s all have the same gear ratios IIRC.
And while the homologation version has different ratios [1,2 and the final drive only] the output from the T case for the propellor shaft is the same as all the others.
The rear diff from them has the same ratio as the others as well.

Front/rear split should be the same, unless the viscous coupling for the center diff is damaged. It's actually an open diff, but the viscous coupling attached to it makes it act like a LSD, except for some early 87 ST165s that had a pushbutton center diff.

Yes, I saw...

and I found one near where I live !!

Too much torque... not power...

[alltracman78]

Ah

Since the 3SGTE is a torquey engine anyways, and since torque is what breaks things, it was implied.
I guess I should have phrased it better.

How much are you running through it?

Seriously,

you can make a 700awhp at 9000 rpms engine with 550 Nm torque, and not have any transmission problem, and have a way lower power, but 650 Nm at 4500 rpm, and have BIG transmission problems...

[alltracman78]

650 NM is 480 lb/ft?

I know a couple of guys that run rallys with their Celicas.
One has right about 600 lb/ft.
The only thing he's broken is his rear diff, and that's because he welded it.

Dunno :shrug:
I'm not trying to be an ass, I've just never seen someone break these.
I hope you sort it out.

And I hope you're right !!!

PS: rallying on an off-road surface is not going to be so hard for a gearbox, even with 600lb/ft...

hey guys

i have a celica gt-four st205... like the other 2 .. tufy and wolf... but i only have about 450 wheel hp.... i broke my gearbox really bad... so bad that you could put it in any gear and it wouldnt move at all.

front diff was missing teeth and crown and pinnon was stuffed. was told gearbox was screwed, i now have a 2nd gearbox from another st205... what should i do to make my new 2nd hand gearbox stronger? i race at the track with my st205.. cheers

and this thread just died? nooooooooooo. these engines can be rebuilt to support more than 800 WHP don't even argue with me on that. I'm sure the dogbox is what people usually use. I'll have to research why fensport thinks that it cannot handle daily driven duties.

[Mstoochn]

the stock E154-F isn't really that strong... it depends how you drive it, and if your using a launch controller than ya that trans is goingto get raped, first the rear diff will start to warp then the fluid in the tranny will burn and there goes your trans.

if you want to end this post do your research, get a damn bias rear diff out of any of the caldina's and grab the awd trans out of it as well

you cant say a trans can hold X power, its all about how you drive, my 5s-gte is only sitting @ 20psi on an E153 and i've already destroyed first gear prior to using my EMS's onboard launch control and im NOT that wild of a driver. (445whp)

[6gtfour]

i think tufy had a special gear set installed i'm sure i read that somewhere. im not sure but i think he ended up using the dogbox eventually. I wish I had more information on what the outcome really was.
