A/G-series diff compatibilty

[JustCallMeOrlando]

Alrighty, I'm back home and have checked it, A01A as I suspected.

[JustCallMeOrlando]

Perhaps C is the Torsen II diffs? That's clutching at straws, because Greg's car should be new enough to have a Torsen II.

[Sciflyer]

Also just to add further confusion, the number codes for the ratio's are different between models that use the same diff

eg, an A01A in a Supra is a different ratio to an A01A in a Soarer, even though they are otherwise the same

[whatthe?]

And I'd bet my left nut the both of those are different to the A01A in the GXE10 (not necessarily ratio, but definitely crown size)

theres some pics (hard to find) on sf.au showing a guy trying to squeeze a G ring on an A centre (or vice versa) and the shoulder mounting sizes/hub carrier size is not compatible, despite it being damn close.

exactly which A series that was i dont know

there is SO MUCH unreliable data on this it make a confusing issue even more unbarable

Another spanner here.

Dads old '98 Prado had an A01A diff stamped on the wall, but it also had an LSD OIL ONLY sticker on the rear diff. I also doubt a 2+ tonne Prado would run a 7.5" diff.

Machineable though?

[ed_jza80]

anything is machinable

also recall issues with PCD etc

[JustCallMeOrlando]

Any ideas what the thread was called? I'm looking now.

[Draven]

safest to assume that toyota made no 2 a-series diffs alike?

[JustCallMeOrlando]

It's pretty much looking that way. Ideally, I'd just get an auto TT diff, but I guess I just have to keep looking around for a cheapie.

[CrUZida]

Get a spare open centre diff, should be cheap enough, and pull it apart, start measuring.

Then post up thread so all can get confirmation.

[JustCallMeOrlando]

Cos I'm in a position financially to do that

[CrUZida]

Surely you can get a blown one cheap cheap ?

[JustCallMeOrlando]

They don't really blow though.

[ed_jza80]

i sold mine for $150

[JustCallMeOrlando]

What'd you pay for your Torsen out of interest? You can PM me if you want. I just need to gauge what a "fair" price is.

[ed_jza80]

bargain basement price - $400 complete with half shafts

$6-800 was about the norm when i was looking

[JustCallMeOrlando]

Were the half-shafts required?

[Sciflyer]

I have a 4.08 Torsen II centre out of god knows what in a JZA80 housing, in my Soarer

Only difference i found was the torsen II diff used axle stubs with slightly smaller driveshaft bolts, but they swapped out no problem

BTW, if youre prepared to wait, there are usually a few up for grabs on Yahoo.jp, which is where i got both of mine
