4x4 LSD's, are they true LSD's

[Shakotan_Aaron]

if you can get a proper aftermarket mechanical lsd. mucking around with stock LSDs is for smucks/tight arses IMO.

best thing i ever did to my previous drift car was go from a stock lsd to a 2way kazz. shimming a stock lsd will only last for a limited time from reports, if your car is going to see a lot of skids rather then just a pose mobil then spend the cash and not have to worry about it for ages.

Car is an 1983 ADM AE86.
Engine is currently a standard 3UZ but will be worked 3UZ and running nitrous, possible tt or sc at later date
Tyres are either 8" wide what ever I can find for drift or 10" wide slicks for drags.

I have never seen a de-dion setup before and I'm not sure how it will work with out using coilovers on an AE86, plus the effort to make this may be about the same as installing the S13 rear cradle making rear strut towers and using all the hardware available to that.

But that said I'm going to look into it and see what it will take.

3UZ.. i vote G series.. even if you have to upgrade the LSD later to something better than stock, the extra torque and future plans warrant (imo) the extra strength of the G series...

[PRIMRK]

Yeh prob should have mentioned a bit more info at the start about my application, sorry guys.

3UZ with slicks - yeah I think G series with an aftermarket centre would be your longest wearing option. Won't be cheap, but will be reliable and predictable. For your application I would anticipate that a torsen centre won't suit.

De-dion looks like an interesting way to keep your unsprung weight down. Adjustable springs aren't hard to install onto a solid diff (same effort for de-dion it would seem) and would be worth doing also.

adapting a IRS set-up isnt all that easy and maybe difficult from a engineering point of veiw. also with 300kw + a s13 rear end is probably getting towards its limits. you would be better with a GTR rear.

for drags you probably want a solid rear end so you have zero camber change.

[PRIMRK]

So are there any after market LSD's for a G series diff? I've had a look at air lockers and the eaton lockers but would much rather a proper LSD.

[PRIMRK]

If I pop down to the drags it will just be for shits and giggles against mates cars, the GTR rear end would be a lil too wide, or at least that's what I would expect, I'm goin to an import meet tonight so ill take a tape with me an measure the track of any cars there with IRS.

[Shakotan_Aaron]

im not 100% of the difference between G-series IRS>live. i know the IRS version has a grove for the clips for the axles but this probably wont effect live axles?

mx83, jzx90, jzx100, mz20, ma/jza70 maybe jzz30?

brands available include TRD, Kazz, Cusco, OS-giken, ORC, ATS, Tomie

[o_man_ra23]

Looks like the LSD 150 series from Cusco might fit. Check to see if the 86-93 Town Ace has a solid G series (xR30, xR36 series)

EDIT: check on these forums for adapting an IRS centre into a non-IRS housing. It isn't too hard at all.

[PRIMRK]

Well as far as I understand centre from the IRS from the land cruiser is a direct fit up so it shouldn't be an issue...

for g series here's a few options

I would say there is a sh!t load more work to get an IRS in than convert to a de-dion, and then it's still an overly fussy Nissan rear-end (or expensive custom double A-arm).

If your intended use is Drag / Drift, a de-dion would still be my suggestion.
The AE86 has proved itself a good drifter with a live axle, a de-dion will not alter this but will improve the weight issue of a heavy G-series live axle.
The de-dion has the advantage also of being able to add camber and toe to the rear, and if you are clever enough, I'm sure you could make this adjustable, which come time for the drags set it back to 0° for max contact patch.

A 3UZ will be awesome I bet.
And if you are contemplating TT / SC / Nitrous (all of which aren't cheap + the 3UZ itself) then don't be so tight on a decent diff/suspension setup.
A well setup AE86 with a stock 3UZ will be a lot more fun than a poorly setup AE86 with a big HP 3UZ.

Quoted for truth.

[PRIMRK]

Yeah I wont argue with that.

I've never seen a de-dion rear end before and I'm not sure how/where to go with it to start...For now I may just get the G series from the hiace and install it so I can use it while researching/making a de-dion.

May have to make up a new thread on de-dion rear ends to pool some info.
