Torsion diff options for a live axle

[Sam_Q]

I am interested in getting a torsion type diff in my car, is there a center that fits into an available housing? Its for my sprinter but I am pretty grinder+welder happy so yeah I am flexable.

I think I could get the aftermarket true-trak for the Landcruisers/hylux? and put it into the crown housing but looks to be too heavy for me

Tarago YR22 F code diff 7 inch crown wheel, 1410 wide, have to change the position of the suspension mounting brackets to fit sprinter, than you can fit and torsion diff that is suited to supra of late model crown that has f code diff

[Sam_Q]

interesting, never heard of this conversion at all, would this be much stronger or heavier than standard? do you know the width of a spritner diff off-hand? whats the year of this tarago?

[Sam_Q]

hey this is still the same conversion that I mentioned at the start right? I am pretty sure I can use the housing out of one of the corona models also. Arnt they a bit on the heavy side?

Sam,

AE86 Sprinter diffs are 1410mm hub-hub wide. The T series (JDM) centres are 6.7"
There is a couple of early Hilux diffs - G series - 8" - that are the right width, but you have to move the mounts from your existing diff over to the hilux diffs as they are leaf spring rear end. you also have to convert from drum to disc. They are also very heavy, the axles are huge.

E and F Series diffs are smaller at 7.1 & 7.5" respectively. unless you are going forced induction I think a T series diff in an AE86 is fine.

You can buy an OBX torsen type diff for a T Series on ebay, I have no idea on how good they are though.

sam, its TorSen, which stands for Torque Sensing or something similar, not torsion. Torsion means twisting, and its what axles in cars with locked diffs do.

Why not a nice 2 way?

Have a look around, I'm pretty sure there are some Torsen type T-series centres available. Check the US trucking/race sites.

Otherwise the F series is a good option. Yes, it's heavier, but a whole lot stronger too.

Go the F-series, you wont break it, and they are still a lot lighter than a G-series

T diffs are for girls

[Sam_Q]

I really dont want the extra weight at this stage but we will see,

thanks for the tips anyway guys. I wanted a torsen (thanks shiny) because I didnt want a harsh engagement and I am under the impression its ideal for going quicker around a corner instead of drifting.

I have been looking into these for my 22. They apparently are a direct copy of quaife LSDs. From what i've read they are bad news if you own a honda (due to a lack of chamfer on the inner spline not allowing CV shafts to be removed) but are reasonable for other cars. There is also a site that details how disassemble and replace the cheap disc springs they come with. Once this is done and possibly with better quality bolts they can handle good power.

This is based on extensive google searching not personal experience. But when i have funds available i will be purchasing one.

The F-series is a good compromise for strength:weight. Torsen is, as you've heard, good for cornering, average for drifting. What engine/power/torque are you planning on running? that will very much affect whether you need to think beyond the wussy little T-series.

And I can get you an f-series tru-trac centre for ~$700

F series trutrac FTW

[Sam_Q]

right now i am undecided to run a boosted or unboosted 4age 20v, i am interested in one of these t series centers but i couldnt find one on ebay, any chance of helping me out on a link?

also guys how would a torsen feel different than a 2 way doing some hard cornering?

Well.... if retaining the OEM diff for mass... Cusco's RS is very smooth engagement do to the small springs on the assembly(shown in purple).... Look carefully at the photo below



NOTE!
Two basic types of limited slip differentials are available depending on how the initial torque is created.

--------------------------------------------------------------------------------


1. Type-RS
�@Low initial torque type using RS springs.
2. Type-MZ
�@Initial torque created by the cone plates.

NOTE!
Type RS for low initial torque.
With the Type RS, the initial torque is absorbed by the RS springs therefore the initial torque comes on gently compared to the Type MZ which comes on stronger as it uses cone plates and response of the LSD is better, as the friction is lower.

*Lower initial torque *Lower power loss *Reacts well to delicate pedal work *Durable and develops initial torque steadily
