Will any year Supra LSD swap into a 92?
Hey,
Ok, here is where you 4 wheeler guys can help me out with differentials and what not
I've got a 92 2wd 22re. Some of you may know about it, some not, but anyways, I'm using it as a drifting truck. I'm trying to learn on it. I am finding it a tad hard to learn on this open diff. that I have now. With a new built motor, no weight in the back end, and my set of roaster tires, I am able to get the thing to spin both tires no problem in most cases, but I'm having trouble getting it to spin both in other circumstances like when the tires get warm and sticky, a grippy asphalt, etc. So, my question is, is there and LSD's that swap right into my Toyota? What about from a Supra? I've heard somewhere that there is a Supra rear end that plops right in. Ya? Naw? If not, what else is there? I like to be able to find one at a junk yard, rather than buy new, or rebuild mine (if thats even possible). Sorry if I'm sounding stupid at all, but I'll admit, I don't know anything about diff's or gearing or any of that good stuff!
Thanks guys

I'm not going to weld it up. I don't like that idea and it's a crappy way to do it I think. I just don't know what my options are, I don't know anything about differentials.

supra lsd will only fit the v6 3rds, i have one in my 4runner wweld it up, or pony up $180 for a spool that does the exact same thing and another $200 for a shop to install it, since u are too classy for a welded diff.

^^ "too classy".... that was funny!
If you have a 7.5" rear you need the LSD out of a celica/supra mkII up to 1980 maybe till 1983. If you have a 8" rear you need the '84 and on unit.
Search LSD under my user name....I posted up all the info you need to decode the diffs from the factory model plate under the hoods of cars at the junkyard or search the celica supra forums.
I know yu can get a detroit tru-trac gear driven LSD for the 8" diffs. The aren't cheap though, plus you'll have set up costs. Also there are lockright lockers.
It all depends on what size rear diff you have.

Sounds like an LSD would be great for your application- if you tighten up the suspension enough, then both rear tires will have a close enough amount of traction available to them so that an LSD would be able to keep one tire from unloading. I wouldn't do a spool or a locker, as they both will eat tires and be less enjoyable to drive on the road than an LSD.
If you probably have a 7.5" rear end on your truck. If you pulled a 7.5 rear end from a earlier Supra, you might be able to make it work.

Shoot, I don't know 
Whatever comes stock on a 2WD 22RE, lol.
First off, I'll do the work myself. No shop fees. Second, are you being a dick for a reason?
Once again, I have no clue. 
You gotta remember that this is my daily driver, too. I don't think I would want, or like to drive a locker in the rear everywhere I go. I do alot of driving.
Thanks for the info!

Why are you "drifting" your daily driver? You are about to have a rolled and totalled daily driver....
My 2004 GTO isnt my daily driver, has a LSD stock, and about 380rwhp/400rwtq, and a M12 T56 tranny, yet you wont catch me doing any type of "drifting"

Not trying to sound like a dick, but whats your point? This is my daily driver, and is also my fun truck. Do I need to have a daily driver, and then another truck as a play toy? Sorry, but I don't understand where you're coming from.
Once again, no disrespect intended there.

Doing a quick search, I read through this thread:
https://www.yotatech.com/forums/f116...-5-diff-74181/
And this post is included in the thread, post #20:
Just to clear up some mis-information,
79-81 (MKI) supras had a 7.5" solid axle, optional LSD
82-86 (MKII) supras have a 7.5" IRS, lsd
82-86 celicas have a 6.7" open diff. ST, GT are straight axle, and GT-S is IRS, but both are 6.7".
86.5-92 (MKIII) supras have an 8" rear end. Turbos had an lsd, n/a had it a an option. The twin turbo R model had a torsen, the rest were clutch type.
93-02 (MKIV) had an 8.5" torsen lsd.
I may be reading it wrong, but to me, it doesn't look like any cars have a 7.5" rear end with LSD that isn't IFS, other than 79-81 that had the option. That seems like a fine window, and will be hard to come by...lol

On a side note, here is a very good link to a useful web blog about Toyota rear ends. Hopefully it's not a repost:
http://home.4x4wire.com/erik/diffs/#rear
Edit........more useful information
First you need to know what size axle housing you have... 7.5" or 8"
You can find out by looking on your vehicle data option sticker on the door jam. You'll be looking for something that looks like this: AO12
The letter "A" signifies the ring gear size.
The next two numbers "O1" signifies the gear ratio.
The last digit "2" signifies pinion bearing setup and LSD option.
In this case "AO12" signifies: 7.5" ring gear/axle housing, 3.30 gear ratio, 2 pinion setup.
The Axle spline count are also different between the two. 7.5" = 27 spline axles. 8" = 30 spline axles.
