What LSD do I have ?

I read lots of things and I am not sure to understand so:

here is a picture of the plate

I hope it's a torsen as I read this one is very good..or else I'll have to do some purchase

The "B" at the end of A02B means that the car was fitted with a factory Torsen LSD.

Cool

Thanks, I read lot s of thing for aftermarket LSD, and most of the time peoples told me to keep this one...

Bonus! Just checked mine and it's AO2B as well.

I'll have to check mine now!

if i have a supra with no lsd how do i find out what one i need, i have a 93 supra non turbo

A02B means:

A - Crown wheel size of 8"

02 - 3.769:1 diff ratio

B - Torsen LSD

but if i dont have a lsd on my supra will it still say on the plate a02b or the other one to let me know which one to buy, its a 93 non turbo auto

The plate code corresponds to what you have.

Most NA auto cars have the code A01A as they have the smaller casing (the first A represents this), the diff ratio of 4.083 (the 01 represents this) and an open diff (the last A represents this). If you were wanting to fit an LSD, the factory option which was available for the NA auto was a Torsen LSD with the 4.083:1 ratio. This would make your code A01B (optional on the prefacelift SZ).

The only NA which came with the 3.769:1 diff was the 6 speed SZ-R (facelift model).

basiclt if it ends in A its open if it ends in B it torsen lsd

basiclt if it ends in A its open if it ends in B it torsen lsd

Yep, further to that, if it says 01 then it is 4.083:1 diff ratio, if it says 02 then it is 3.769:1 and if it says 03 then it is 3.267:1.

If it starts with an A then it is small case (8" crown wheel size) and if it starts with B it is big case (8.7").

Rite were can i get a b casing

Stupid question then, what are the advantages of a big or small case?

Oooh I have a B03B! Thanks for the explanation

Mine is a j spec though with a B03B how does that work? Or does the U.K not stand for uk?

That information except U.K. spec came from here.

But there are some 'differences', more info here.

Don't forget A05B, which is a USDM 4.273 with Torsen LSD.

I have one.

What engine/transmission is with your AO5B?

Anyone with any other codes for the record?

My jspec TT is also a B03B with a V160 (6MT)

Are these J spec B03B's 3.266 or 3.133?

What engine/transmission is with your A05B?

W58, 5 speed manual.

I'm nearly sure thats the correct model number for the diff, it actually came from a USDM Lexus SC300 but the USDM NA Supra had the same diff for a couple of years.
