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

[The Witzl]

the AE95 are the same splined axels as the kouki (ie tough as guts) AE86 but the spline length makes them unusable

I'm going to refute the above statement - There is no such thing as a "tough as guts" T series diff or axle.

Compare the kouki(??) T series axles to that of an F series or G series - you will see

[takai]

Also, its not the spline length which makes them less usable, its the fact that they are 4x100 not 4x114.3

hahah very funny karl
its the toughest t series there is though.

and takai point taken.
is there no way to change it?

Sorry dudes! I mixed up the rare/common ratio bit. Will edit my post to correct it.

The Aussie build MS55 and MS65 had Holden diffs, not Borg Warner. Holden actually built them for AMI under contract. They were a 3.9 ratio course spine diff and still had "Holden" stamped into various parts. Basically the same assembly as HT Holden except for ratio. Any Holden banjo centre will fit as long as you use course spline star gears. These are the models that have the much sort after front hubs for the Supra five stud conversion.

Never seen a Crown with a Borg Warner diff??

BTW AMI stands for Australian Motor Industry they assembled some Crowns, Coronas and Corollas. They even assembled Rover vehicles.

They pretty much took a good car and ruined it "for Australian conditions".

Cheers,
Shane.

Hi,

Looks good, but isn't your "ratios" column incorrectly labelled. This looks to be part of the diff code and not the ratio. For example, the RA25 GT diff code is "5F2-F313", which (IIRC) makes it a 7.5inch 2-pinion LSD with a ratio of 3.909. Also, the RA25 GT has drum brakes on the rear.

MA45 - T series. MA46/7 - F series

MX10, MX12 were E series. MX22 auto is E312.

MS65 had Borg Warner diffs. AMI built MS55s had Borg Warners too.

Pretty sure most/all those early Corollas (KE1x, KE2x) have U series diffs in them. After that they had Borg Warners or U series depending on whether they were made in Japan or AMI.

RT81 had a Borg Warner or S series diff depending on whether they were made here or in Japan.

done..........

89 Tarago with the F282 is a YR22.

Hen

yeh i found your post in the "f series diff ratio availability" thread. thats were that came from

changes made there also....

[SeptemberSquall]

<1973 TA22 manual had 4.1:1, D series 6.67" rear end
>=1973 TA22 manual had 4.1:1, T series 6.7" rear end

4.3:1 T differential was available in TA23 auto as an option only.

Every australian TE72 liftback (T-18) I've seen is 3.9:1.

[Garth AE86]

theres the answer i wanted
cheers mate (+rep 4 u)

if u can break a T series with 67 fly wheel kw then i wouldn't call them strong at all !

Props for putting this info together mate ur gunna help out alot of ppl !

[ed]

that a and b series stuff is incorrect

a series is 200mm crown wheel, b series is 220mm

im not sure how those numbers got so popular, or what they actually refer to!!

[The Witzl]

the ratio / sizing info brettles here has been referring to is the chart available from the Toysport website.

Unfortunately this information doesnt hold for the "new style" gearbox / diff codes that Toyota has been using since the early 90's.... this includes the A series diffs now used in the Hilux and Supra.

Basically - if it's 1990 or newer, disregard the chart above


Now, some use[less] info from Teh Witzl!

# RN2* Hilux = 1370mm width, will measure drum size tonight
# RN4*/YN4* Hilux = 1410mm width, unsure of drum size (i think 8"?)
# UZS131 Crown = G series, IRS, G474 code iirc, non-LSD
# AE71/KE70 = ghey bog warmer, 1410mm width, p00
# TE72 (aka T18) = T sereies, 3.9:1 ratio, open centre, 1410mm width


*****NOTE: AE71/KE70 driveline is BOLT IN replaceable with TE72 T-series gear (you need TE72 gbox, tailshaft and diff)

[brett_celicacoupe]

can anyone tell me the presise width of the MS112 diff.

so far ive read of 3 different disk-to-disk widths

need to know if width will come close to the RA40 width.
