Hell this is nice, just add one Supra LSD and you have a stronger diff ,with 4 pinion gears, than virtually ANYBODY and a full range ring and pinions from 3.73 to 5.37 for CHEEP.

Drilled for US XR4Ti bolt circle or 2wd Cosworth bolt circles.
Assistance available in hooking up your propshaft...






Hope this helps...

I have one fitted in a car thats being built now ,will be some time before i can give you the SP tho .
Not sure about cheap but certainly in the right ball park to be worth considering .

10.5" Jag Diffs are cheap as chips & very very strong.
My 3.54 power loc was Ł20 (swopped for some Tesco Wine) reconned for Ł400 & has completed 9 years without prob. Will take 800+FT-LB.

Is it possible to change the jag diff to a 3.9 ratio?
Cheers Rich

Depends who you go through really.

I had asked in the past and it was far cheaper than a Gripper for example.

I'm sure it will be a good diff, I'm just not the sort of person that wants to be a guinea pig and wouldn't advise anyone else to be either unless there is a good reason to be.

Ł880 Retail for a plated diff with Cintered plates is an absolute Bargain even at retail money . Their 7" versions are well proven in Caterhams and the 7.5" i have is well built and can be pre-loaded to my requirements ,they fucked up by not letting me test this in a racecar before releasing ,instead choosing a trackday outlet for it instead ,fools ,lol .

Hi Pete.

I'm still on the T5 with the Quaife big tooth kit, still working ok, must be around 560lb/ft and 670 brake now. Oh, and it's now done about 10k miles since I fitted it in 2004

Cheers,

Ade.

I guess if you look at it like that then yeh its a cracking deal. There aren't many Caterhams with 500+hp though !

Come to think of it isn't rammer rainbird running one in the Escort now ?

interesting about the supra diffs

janvanv

Hey madmen, I'm the guy that is doing the Supra diff kit.
The idea was that I wanted to do several things at once since our US market cars never had the option of a LSD and Cossie diffs are still only 2 pinion design and no easy method here in the US to up-rate the VC like you can there.
So I wanted:
a) Easy availability
b) big increase in strength with 4 pinion LSD
c) wide choice of ratios
d) easy install

The MkIII, MA70 Supra diff meets all these demands with a wide margin.
Those Supras, while not my cuppa tea stress the diff two ways: big 3,0 liter turbo does make some poop, that's stress, plus it is a real pig weighing in at maybe 3500lbs, and weight is stress also.
Drift-looonies claim they make 700bhp in those motors easily and report no problem with the unit, sounds good to me.
Granted it weighs about 17 lbs more than US market Xratty (Xr4ti) open 7.5 diff but anything bigger and stronger is going to weigh more.

It's 40mm narrower than a Ford 7.5" diff and its inner CV bolt up is BIG making the adaptor rings easyand as Kevin "the Bronze" mentioned I make the adaptors ready for 2wd M10 bolts or the US (and 4x4) so called 100mm CVs with the M8 bolts as well.

Toyota trucks are extreeeeeemly popular here for playing in the deserts or as rock-crawlers in the mountains with big tires so there is an enormous range of alternate ratios if the standard ratios don't suit you.
Guys I know in the diff business say the bearings are the size of US Ford 8.8" diffs and very strong.
Standard ratios HERE are:
Early turbo manual box: 3,9:1
Later turbo manual box: 3.73:1
All years turbo autotragic box: 4,3:1
All years non turbo with "touring package"...4.3:1

But there are endless choices since Toyota used the 8" in a lot of vehicles including some of their vans in 3.73 or 4.3, in pick-ups at 3,9 and 4,1 and 4.56
And the prices for new range from 155-225 USD for new crown wheel and pinion sets.
Crazy!
Hooking up the propshaft is easy enough with weld in yokes and a nice flange for the companion flange that use a BIG Spicer 1310 u-joint.

The kit is USD300 and the propshaft parts are about another 100 US.


I've seen MkIII Supra diffs go for 50 squids there in UK.

If you're interested, the e-mail above does work or better is the same janvanvurpa but at gmail dot com rather than the old F4.ca addy.
There is the phone too but you guys better not call at 0430 like one guy did.
We're 9 hours behind you guys so 7PM would be NOON here.

NOTE: If you find yourself at the breakers with tools in hand to pull one, save the 12 nuts for the Supra inner CVs, they're some reduced hex fine thread Japanese thread ( I believe it's M10 x 1.25 with 14mm hex, you'll have no joy searching for the 14 hex.)
Also save the propshaft to companion flange bolts, this time they're nice shouldered M10x 1, nice fasteners so save them.

You high HP boys that want to really launch hard would be well advised to consider doing as Ford did in Motorsport as carefully described in the old "How to Prepare the Sierra for Motorsport" book regarding using a solid spacer between the pinion bearings rather than the OEM collapsible spacer. The pinion tends to "screw in" when you pound the pedal down and "un-screw' when you let off, and repeated heavy applications of the "full wellie" tends to pound the collapsible spacer and it shortens and you loose the correct pre-load for the pinion's taper roller bearings---and failure is the end result.
Pretty damn hard to collapse a solid steel sleeve.
Kits are available for the Toyota 8" unit for $18-25....but anybody with a lathe could make a spacer in a few minutes....
That's the only complaint I've been able to find on the Toyota diff but in truth it applies to all pinion set ups with the bulgie type collapsible spacer (as we see, Ford says do it on their own units)


Note! 4x4 boys can find 3,9 front diffs easy enough, now you can have an unbreakable rear diff with same ratio...

Oh and I should mention, I haven't gotten any emails so look at the email addy above, and I'll check and see if I have some old email addy in the user area and change it.

Updated email from dead account from years ago! When did I sign up here, last century?
Also cleared out PM box but boys, email is better, phone the best.

Sorry to say, but I bought Supra diff from this man and when we checked the diff, the pinion was broken. The diff was stated to be in exellent condition

janvanv

Hejsan, det verkar som det är lite problem dĺ och dĺ med email.

Du kan oxo Google ''JVAB Imports'' och där finns ett email adress som vidare skickas till gmail adressen.
