Just a minor correction for the USDM 1998 NA, the torsen lsd was standard in 1998.

World's First Naturally Aspirated MKIV on E85:
from feb 97 on the v161 was in all jdm sz-r's along with the torsen but as for the usdm dunno
The thing I have learned is that the JDM supra's were very personalized depending on owner. Meaning All options were on the table when you brought it from the dealer. The biggests thing I see is the brakes, transmission & lsd's.
Mines E-JZA80-ALFSF (6MT)
and its a 96, and the only SZ-R's with 6psd I've seen are from 96+, before 96 I've only seen 5spd

I believe the SZ-R was only available from 96 onwards, prior to that the model was just an SZ.

First off ... depending on which chassis you are talking about, the 'meaning' of the codes changed. To keep things simple for sake of explaining, let's compare the diffs in the MK3 (G Series) and the MK4 (A or B series) as they have been called ...
Old school example: G285 ... The G described the housing (size of ring gear and solid or ind axle), the next 2 digits told you the gear ratio: i.e. 28x = 4.30 gear ... and the last digits told you whether you had open diff or limited slip ... if the last digit was a 2 or a 4, it was open diff, if it was a 3 or a 5 it was LSD, and there is a universal chart that list all the combinations ...
The newer axle codes aren't universal between chassis ... i.e. an A01A in a Supra is going to be different from an A01A from a GS300 (except for one thing) ... so lets explain the newer codes ...
Let's look at a USDM MK4 Supra TT Auto:
A01D 'should' be the axle code
The A means it is the standard diff for the chassis (B would mean it is the optional diff if available)
01 is the gear ratio, but the difference is the 01 is chassis and market specific now.
The last letter D means it is a full 2 way torsen LSD
C = supposed to mean 1.5 way torsen LSD (I have yet to see one)
B = supposedly is only a 1way torsen LSD (every JDM LSD diff I have seen has this code)
A = Open Diff
Now take the 94 USDM MK4 Supra TT with the optional 6spd V160 and it's axle code 'should' be...
B = The optional diff for that chassis
07 = gear ratio 3.133 (specific to the USDM Supra)
D = 2 way torsen LSD
In other words the B diff now doesn't always mean it's a 220mm ring gear .... just go look up the current trucks from Toyota and you'll see what I mean!
I've also personally seen a B03B diff from a JDM Chaser, and it had the housing of a 200mm ring gear ....
It just requires a 'different' way to think about what the codes represent, and what makes it more complicated is, you can't just go by the axle code anymore ... you have to at least know what market and chassis it came from, I.E. JDM JZX100 B03B for example ...
In the USDM Supras ... the ratios are supposed to be:
01 = 3.769 (TT Auto)
02 = 4.272 (N/A Auto, N/A 5MT)
07 = 3.133 (TT 6MT)
This information wasn't easy for me to compile ... and I don't guarantee its accuracy, however I have more hours talking on the phone with importers, service depts, friends, jdm import shops, and last and not least toyotareference.com which shows what is 'supposed' to be available for the chassis than I care to admit to bring this information to the community.
89 Supra (2JZ-GTE VVT-i)
94 Supra TT
99 Aristo (2JZ-GTE V160)
07 Tundra CrewMax
This was further complicated by accidental coincidences, such as my own beater Tundra's A01A diff code matching the open 4.083:1 200mm ring gear description perfectly, albeit in a live axle configuration. That led me to believe it was universal and not platform-specific. Thanks for the clarification!
We're all human, no need to be smarmy about it. I wasn't wrong, I was just working with conflicting information and there was no clarity on the fact that the codes are platform-specific. That changes everything, obviously.
I'll clean up my posts in this thread with the new information when I have the time to give it the attention and diligence it deserves.
SZ 93.5-2002.7, 5-spd & Auto---- 4.083:1 (LSD optional) small diff, small flange, Code A01A (LSD A01B)
SZ-R 94.5-96.5, 5-spd---- 4.083:1, LSD standard, small diff, small flange, Code A01B
SZ-R 96.5-2002.7 V161 6-spd---- 3.769:1, LSD standard, small diff, big flange Code A02B
RZ & RZ-S 93.5-95.5, V160-6 spd---- 3.266:1, LSD standard, big diff, big flange, cooling 'ears' on diff cover Code B03B
GZ 93.5-96.5, Auto---- 3.769:1, LSD standard, small diff, big flange, Code A02B
RZ & RZ-S 93.5-2002.7, Auto---- 3.769:1, (LSD optional) small diff, big flange, Code A02A (LSD A02B)
RZ & RZ-S 95.5-97.8, V160-6spd---- 3.266:1, LSD standard, small diff, big flange Code A03B
RZ & RZ-S 97.8-2002.7, V161-6spd (2JZGTE vvti)---- 3.266:1, LSD standard, small diff, big flange Code A03B
To make things easier for you I've changed/added all the above with the correct info so you can just copy paste it in.
B03B is the only JDM diff ever released with the 'cooling ears'
European-delievered TT 6-spds (and autos) with an OEM external differential coolers did have the 'cooling ears'
The info above should answer most of your notes/more info needed section.

Does anyone know if the LSD diff out of an auto TT will swap into the pumpkin from a 1995 na auto? The 93-95 na's and TT autos had the same beefy axles and the part numbers for the TRD LSD for the na mkiv and TT auto are the same thats why i'm asking.
