Sorry, Steeeeelies, this should explain it for you (Goat has)...

kicker, not sure as yet but thank-you. I'll see what is in there now and then try and figure out what I need using mathematics.

Don't expect an answer immediately/in the next year.

It's the ratio.

A01B = 3.916 ratio Torsen LSD

A02B = 4.083 ratio Torsen LSD

That's according the the UK IS200 owners club, there's also a 4.3 found in some Altezzas, A03B I believe.

The B on the end means it's got an LSD center, if it ends in A it's an open centre.

Toyota changed to the stupid fuckin' convention of calling every diff "A" something instead of T, F, etc.

 

I think the confusion can be that some "G" series diffs are called A as well.

 

But I think only the Gita wagon or something like that came with G series? Or none at all of the altezzas?

 

But some other cars have a "G" that starts with "A"

I've seen an Altezza diff swapped into both the older IRS housing and older live axle with no issues.

If you get an Altezza LSD theres prettty much 100% chance it's an F series.

 

then if it's a G series torsen you can sell it on for big bucks haha. So cant go wrong.

Yeah Celsiors and Hiluxs etc diff codes are all A0xx now too, but the numbers coencide with different ratios depending on vehicle models, and seemingly no reference to size, so a A01B tezza and A01B Hilux is completely different. Stupid system.
