Toyota diffs. All data being collated onto one table. Specs/input needed (RWD)

i think it's only the earliest model, but my mx22 ratio is E072

[RT104GT]

From some hulks today

Crown F292 7.5 4.100 2 open

Celica RA40 T292 6.7 4.100 2 open.

Cresida E302 3.727 2 open

T18 had a 3.727 also T diff

Just measured the width of my live axle Borg Warner RT142 Corona Avante. I got 1430mm measured from the mounting face of the disc. Looks like she will cop a G series

[Dimitri]

lite aces are E code and as much as ive seen 282.

jap 86s are t282/283 ( lsd less common than is widely thought) same ratio autos and manuals.

[Robbman]

does anyone happen to know if lsd centres can be swapped from a g series supra diff to the hilux g series diff

craig

Yes they can.

Not exactly true, due to different bearing sizes, you cannot directly swap a 4-pinion carrier into a 2-pinion G series solid rear housing, not to mention the gear set issues. The 4-pinion G series LSD carriers from an IRS are a direct swap ONLY if you have the 87 and later reinforced solid rear diff (4-pinion). In general, this diff was used on 22RTE and V6 4WD models, but there are always exceptions...

The middle carrier in this picture is the 4-pinion reinforced carrier, the one on the left is the 2-pinion solid rear G series carrier

That said, Precision Gear makes a master installation kit that includes bearings that will allow you to install a 4-pinion carrier into a 2-pinion housing and also use 2-pinion gear sets... but that's not really a good idea. Your money would be better spent finding a 4-pinion housing

[RT104GT]

I once had an AE-71 wagon. Leaf sprung, drum braked S seies in a 3.909 ratio. I fitted an MA-45 T series diff to my AE-86, also a 3.909 ratio. In the paddock I have a Corona RT-142 IRS diff housing, F series, which I am 99.995% certain is ALSO a 3.909, will check this in the next week. Have a manual SA-63 and auto RA-60, both T series, both 3.909 (sigh). Am soon to aquire a 4.1:1 ratio from an auto RA-40. T series. And I ripped a centre from a Cressida which I swear is a T series, 3.707 ratio. No idea if it was auto or manual.

cheers

Yeah well Toyota served the masses didn't they 3.909 like assholes everyone had one.

Not so bad in traffic pretty OK on the 60 mph speed limits of the day.


3.727 in the TE series was the other standard.

Non standard are the 4.100 & more so the 4.111 (GT's).

Why 4.111 fast off mark and high top speed.



Good overtaking in 3rd to 7000 rpm 150 kph
4th to 7000 rpm 190 kph.
T/S in 5th at 6800 rpm (zero % efficiency a.k.a. FLAT OUT) 220+ on an 18rg with 4.111 and 14 inch wheels.


Wagons and utes 4.375.


Rest unsure.

Nissan nused lots of 3.700 but not so Toyota for some reason.

[brett_celicacoupe]

Non standard are the 4.100 & more so the 4.111 (GT's).

not even steven,

all (read nearly all) the aus delivered TA22s, RA23's, RA28's, RA40's and even MA61's a 4.1:1

i also sigted a 92' model 2wd hilux the other day that are G292 (4.1)

Whats the go with E series differentials? I poked my head under a few taragos at a wrecker and the centre casings look pretty big on them and some had reasonable ratios too and discs I think.

Has anyone ever used them in a performance application?

[Norbie]

Very difficult to find aftermarket centres for them and there weren't many OEM E-series LSD's (I've never seen one), so they kinda suck for performance applications unless you're happy to weld it up or leave it as a single-spinner.

F series is a much better option if you want access to aftermarket goodies.

[sv_i]

ahhh gotcha.

was just thinking aloud, cheers for that.

[sv_i]

next question:

what sort of differential is in a Toyota 60 series Landcruiser.

My question is because, would this: http://cgi.ebay.com.au/Toyota-60-ser...QQcmdZViewItem

fit into my shortened Hiace Van diff (assuming G series).

[Norbie]

No, Cruisers use some monster diff which is way bigger than the G series. It's 9 3/4" or something crazy like that.

[sv_i]

bum. Cheers for that.

Brett,
Good work so far on the diff doc.
Is there an update coming soon?

Norbie,

Do I need a password?

I've been adding more stuff to my own site.
As you've already seen, I've tried to list the diff for each model.
I've also been making a list of crown and pinion part numbers.
Feel free to copy what you want.

I'm only halfway through typing in the info I've got but I've already covered most of the cars we actually care about (only just started on JDM Corolla, to be followed by Corona).
Australian cars assembled by AMI often have Borg Warner diffs that start with the code AM (eg AM70).
Mitch asked Borg Warner if we can still buy an LSD for these and they said the LSD's are well and truly out of production.

There is a story in "The Long Run" (history of Toyota in Australia) about how the Holden diff found its way underneath the AMI assembled MS65.
I will dig it out and post it when I find it.

One thing to be aware of, it was mostly (but not only) GT models that had LSD. but even there it was only optional.
For some countries like the UK, the RWD Celica always had LSD on the GT models, while for other countries it was a rarely used option.

A *general* rule is that an 18R-G/GE/GEU/GU engine will usually have an F series LSD (eg RT104 Corona, RA2#/3#/4# Celica).

Somebody asked if the RA35 has discs.
No Celica A2#/3# ever had rear discs.
That had to wait until the 4#.

Another useful little rule I've found is that a Celica/Supra/Carina 4# always has solid axles, while a Celica/Supra/Carina 5# has IRS.
