-Imported MA61's come with 3.73 diffs (F303).
-My GA61 came with T312 (3.9), but I've never seen a GA61 with a 3.73 diff.
-Automatic aus-spec MA61's came with 4.1 LSD (F293)
-If a GA61 with a 4.3 LSD it would definetly be F283 not F285.

so that means i have a 4.10 diff ratio so if i got a smaller diff ratio (ie 3.5) would that mean i would get greater top or bottom end speed?

All auto MX73s have 4.1:1 Non LSD (F292)
I believe the manuals would have had 3.9 or 3.73, but there were none brought to Australia, so forget that.

Ok that the ratios , but are all the housings , bearing etc all the same ? Is there a long / short nose carrier difference are are they all the same length externally . Are all ten nut / bolt housings . Is there any markings on the crown wheel / pinion to say what the gearing is ie:12/49 etc .

ok, just to throw a curve ball, many years ago {20}I brought a disc brake rear end for a rally car and it was supposed to out of a RA28 GT.It uses 7,5" crown wheel and pinion and all the spares i needed came from mk11 coronas except wheel bearings as they where then deemed enourmous.After ditching the shell and keeping the diff I have found out that the disc's are the same as AE86 as are the wheel bearings and the calipers are similar to AE86 however the axles look like 9" ford they are that large.
As i am travelling thru Europe at the moment and the diff is stored in a 40 container I have no way of helping with this puzzle by confirming anything, however the diff housing has now been converted to AE86 and I believe that the original housing may have fitted an AE86 with no trouble, I cut the original brackets off to fit KE35 with 2TG,when the housing was measured for fitment to AE86 it was within 4mm of T series housing width.
handbrake cable attachment to caliper from what I can remember are the same as AE86.I have fitted TRD lsd and 4.777:1 ratio to it.

squeak,
The RA28 GT did have an F series (7.5inch) rear end, optionally fitted with an LSD. And, as the RA23/28 and AE86 have similar rear track dimensions, that length axle will always fit a AE86. After all, Aus spec RA23/28 and Sprinter all had T series rear ends.

You are talking overseas / JDM models here, correct ? The RA40GT and the TE71 Levin/Sprinter/Trueno (delete what ever is not applicable.)
The RA28 GT (with or without LSD) F series rear end was drum braked.

Yo, im reading that the RA65 celica has a F372 diff, or possibly an F302 ?? i keep hearing that the MA61 LSD will fit the celica, but will both the F313 and the F283 fit ? or will more/most/all the F series diffs fit ???? just needed to know, as i read heaps about F and G series lsd diffs, but most of the time they dont have codes so i kind of thought they might all be interchangeable with in the same series.. correct ?
peace yall

All F series diffs are interchangeable. You can put an MA61 LSD in a Celica IF the Celica has an F series diff to begin with (eg RA65).

Jzx90 MarkII 1jz-gte, Non-LSD .... trying to find out what diff's are compatible and would bolt straight up.
Soarer is apparently same (Jzz30) but Jza70 Supra is not apparently.
Does any1 have info on the diffs for these cars?

A JXZ90 will likely have an A series diff, same as JZZ30 and NA JZA80. JZA70 has a G series diff, as do all MkIII Supra's.
I've heard the A series (new coding scheme) is the same as the G series (old coding scheme) but I don't know anyone who has confirmed this first-hand.

I can confirm this, as a mate of mine took an A series LSD from his JZZ30 soarer as it was rather worn and replaced the centre with a normal Clutch LSD from an MA70, it fit straight in
obviously the casings are different

Do a MS55 have a F-Diff? cant find any id-plate.
Is it possible to put a F-diff in a E-house if you change the size of the bearings and washer? or is the crownwheel simply to big for the housing?

So ok..
question i have is ... the stock diff is an open one, as it spins one wheel on corners.
Without going over the top, what G series cars came with LSD's.
Obviously the manual Soarers Jzz30's do, but finding one of those factory is rare.
What G-series car stock come with lsd's etc....

And...
Does the Factory LSD centre from that diff, fit into my open diff and make it LSD ?
I heard LSD factory diff's had different shaft lengths, where open wheel diff's had equal length ones.

Mk3 Supra and later model Hilux's are the most common source.

"LSD" only applies to the diff centre, that's the only part that changes. There are no shafts in a diff centre.

The secret is to look at the build plate, which is usually rivetted to the firewall under the bonnet. If the axle code ends with a 3, 5 or 9, it came with an LSD from the factory.
All Hilux's have a G series rear diff, and LSD has been optional for at least a couple of decades. There's no way to spot which ones have an LSD fitted without checking the build plate.

no, johnny. the housings are different sizes sorry, tried it already. if you were were a good machinist or wanted to pay lots of money, you could make it fit, otherwise change the whole diff.
what do you want a diff change for? If you haven't already, then test the diff you have first. there's no point changing the diff if it doesn't need to be, coz all your doing is adding un-necessary rotating mass to your driveline as well as sprung weight to your suspension, which hurts your power and handling.

The E-diff wasn't for the MS55, it's for my TA47 with 3T-GTE.
I think i will go for a MA61 rear end if i dont find anything better.(some other YR2* that not have this E-serie diff
