They're both Corollas, the AE9x was made from 87-92, and the AE11x was made from 95-02 so I think that's what we need?

And about now is when I'm mad that my car is RHD haha

wow thats exactly what i was looking for, so let me be extremely redundant, since I don't have an account with gt4 atm.. Use the ae92 rack but what tie rods exactly need to be used? thats kinda exciting news especially if a steering rack is going anyways..

Any idea if an AE95 has the same mounting/ratio as an AE92?

Steering is more direct it seems. I may try the AE92 rack like stated above with an MRS electric power steering pump next.

Is there anywehere a writeup for depowering a rack. Very interesting. So if I depower an AE92 rack then I can put this on it? Any thoughts?

Look at their electric power steering. And what a good price for a universal kit.

Thanks for the link. The only issue I have with actually electronic power steering is the wifes old G6. It had little to no road feel with its electronic assisted power steering. Will have to do more research on this though. Would be a much cleaner install than trying to run an MRs electric pump.

If it fits then yes you could depower it and get the reduced lock to lock. I pulled alot of my info from a miata write up but I never got around to doing one for ours. Its pretty much the same thing. The torsen bar I had an offroad shop local to me replace it. They only charged 40 bucks if I remember correctly. Just beware... Its great on the highway but a bit heavy around 30mph and really heavy at a stand still. Other downside is I noticed the car "follows" the road more. Any kind of crack or line in the road it will try to torque on you.

My objective is to simlify steering in my rally car. Get rid of expencive high pressure hoses an noisy pump. This electric setup has been used in rally extencively over last 5-7 years. MK2mania and others simplyfied the electronic part of it so it can be retrofited to anything with a non hydraulic rack.

Ok so exactly which AE92 rack is needed? Because there are apparently 7 different AE92 racks and I need to know which once to order.

After looking at the EPC, it is true that there are at least 8 different part numbers listed for the AE92. The part numbers vary based on whether the car was made in Japan or North America. What it really boils down to now is that half the part numbers appear to be no longer available from Toyota and the other half of the part numbers have been substituted by just one part number that is currently available, 44250-12231-84. (available as a reman for $235.32 at Titus-Will Toyota)

Ok gotcha, do you happen to have the number for a RHD rack?

There are 4 different numbers for JDM right hand drive AE92 steering racks. You'll have to narrow these down as none of them would be available from US dealers.
44250-12200
44250-12201(substitute for 12200)
44250-12210
44250-12211(Substitute for 12210)

In Australia, i think power steering was an option on AE92s.
So there are both powered and non-powered racks here.

ok so this thread has interested me and this is what ive found.

ae92's have the same power steering rack except for the gts and apparently the gtz. the gts has a variable ratio steering rack that runs off a vac line and the gtz (rhd) seems to have a better lock to lock ratio. info can be found to TN here.

AE92 GT-S P/S rack: 3,25 turns lock-to-lock
AE92 GT-Z P/S rack: 2.5 turns lock-to-lock
Might be nice to save this topic for future reference?

http://www.toyotanation.com/forum/134-6 ... racks.html

so whats up with all of this 1.6 lock to lock stuff? if its out there id like to try it out but from what ive found it doesnt look like the ae92's had a 1.6 lock to lock steering rack :( .... ill do some research on the ae11X's later

im trying to understand why you guys wanna change the rack?
sure less turns lock to lock but how is that useful on a street car?
i always thought the biggest issue with any gt four was not enough lock?
only benefit i can see is for motorkana or maybe rally
