Hello peeps, just wondering I drive an 89 5spd turbo mk3 and the diff is gone, ran low gear oil for a long time til i fryed it. My question is can i run a diff from a 1991 automatic mk3 turbo, any one know what the gearing difference is and will it fit my 89? thanks :1zhelp: cheers.........

You can check using the search button on here, but I think they both have the 3.73 gears in them. I'll probably ended up being banned for giving you the wrong info, but that's my answer and I'm sticking to it. There may be a difference in the early 89 and late 89's but I know you can use the one you're talking about. Good luck
I think this would also qualify as a techincal question, which means this is in the wrong section. You'd have a better chance of getting it answered if you post it in the right section.

I think the problem would be a diferent amount of teeth between the diffs. I may be wrong though. If they are the same ratio I don't think it will be a problem. If they are diferent you might need to have a custom driveshaft made.
i believe your diff is 3.73 dunno with out your axle vin code toysport tells more on axle codes!
Auto though haves 4.30 because the final gear on an auto is .65 the manuel is around .75 or .78 on final gear.
So the auto 4.30 is good for drag racing and stop go driving non daily driver clutch set ups. delivery jobs etc..
it sucks though on gas milage & top end performance you will rev a lot higher doesnt matter really if you have a 8k reving engine like a 1jz but on 7m you will rev around 3300 rpms going 70mph in 5th on a r154 with a auto 4.30 lsd.

The weirdest hardest to get rear diff is the group A mkiii the race ones for toyota they had 3.20 perfect for v160 6 speeds but they made less then 10 of those diffs in the world.

if you're referring to mkiiitech, try actually READING the information there....
Auto, 5-speed, same diff.
87-88 Turbo is 3.91:1
89-92 Turbo is 3.73:1
N/A is 4.30:1

Sport package N/A's always had a 4.3 lsd.
NO turbo cars came with 4.3's. At least not in the US.

I thought the turbo charged automatics come with 4.30 LSD
or should have come with them the automatic should drop the hp so much they went with the weaker diff.
I know manuel turbo comes LSD for sure.

The first page bud.
He was talking about a turbo auto diff and you started talking about auto's with 4.3 diffs.

sooooo, exactly where is my info wrong? sounds lke you're confused...torsen = helical style LSD. clutch pack = clutch-pack style LSD. where's the problem?
MA70 NEVER got a torsen LSD. they were clutch-pack only.
Durr... ^Same thing I was going to say 
. No where in there did it say MA70 and Torsen in the same sentence .

My bad
I have been mislead by a lot of people telling me the torsen is the clutch type on ebay and other places there is no mistake on the thread.
torsen ='s helical ='s worm gear ='s pinion lsd.
I have always been mislead to believe that tosen ='s clutch lsd
what ever you do dont get the clutch lsd and when you see oem 4.1 jdm torsen on ebay it is the clutch and not helical/pinion/wormgear
please accept my apology
