4agte 160kw diff choise

[jontrueno]

hey,
i have a gte and was thinking about changing the diff from a zenki to something else,
i was told an F series from a tarago would be the go?
does anyone know if this is true?, if not what would be? how much? where can it be done in nsw?
cheers
Tim

Hey i got a tarago diff going in my 4agte best one as its same size doesnt need to be shortened and has lsd available, i got quoter 590 to swap all mounts over and do a basic inspection, this was from diff technics kogorah.

[af300e]

Ae86 diff 1410mm
YR20 diff 1450mm
MX13 diff 1425mm
MS112 diff 1450mm

Pretty sure that's right. Someone will correct it if i'm wrong. Pretty sure a tarago diff needs shortening if you want neg offset wheels.

MS112 is good as they are 5x114 pcd. Add a MS65 5 stud front conversion and your wheel options open right up (same stud pattern as fords for the last 25 years).

MX13s are 1410 wide, not 1425.

[steroidchickens]

F series is a great diff. but tarago is around 20mm wider each side.
you will have to get all the mounts changed from ae86 diff to F series.
can work out quite expansive to do it properly.

I'm doing a f series at the moment,I'm paying
yr 22 - $350 (some places asked over 600)
Lsd plus a bit of extra shimming- $250
converting mounts - $4-500
straightening the housing - $100
total $1200 with me removal and fitting.
on top of that I'm doing r31 rear disc setup
calipers,mounts,cables - $160 got ripped on these
new pads and discs $200ish
and still gotta sort out the hand brake cables too work
some things are mates rates but it starts too add up real quick,
the plus side is the axles and bearings are heaps bigger so
can take an absolute rapping.

I have a mx13 in my sprinter, I fitted the mounts etc myself. The mx13 housing alone is 14mm wider than the s series from the sprinter. I know this because I had to space the jig I made to accept the s series housing by 7mm each side before I cut the mounts off it.

I got hold of a T-18 diff and had a Borg Warner LSD set up for it in Rydalmere, at a place called Award Differentials. All up it set me back $1700 plus fitting and freight to Albury/Wodonga. it's a pretty good set up for getting sideways and straight line launches.

We're talking about the overall width of the diff mate. From outer hub to hub, it still measures 1410, give or take 5mm. I've already done 3 of these and just measured up my spare to confirm. The total width will depend on the thickness of the brake or drum setup you decide to put on it.

why not just use a R31 diff, mine cost $350 to convert the mounts, all I've got left to do is handbrake cables.

and the best bit is it comes with R31 rear disc brakes

[Big T]

^^^^ Because r31 diffs use a shitty cone type LSD which needs constant rebuilding to work well. It's been a while since i looked into it but i also recall one side of the diff being longer than the other, ie the hemisphere is offset and has one long, one short axle. Make sure they do the mounts properly for it if this is the case as you don't want a crooked tailshaft after its all bolted in.

A R31 lsd is about as gay as a stardard F series lsd. that's why i spooled mine.
and there ain't no off-centre diff here, mine sits dead centre.

[jontrueno]

So about that spare rear end you have Big T, is there a price on that?

[Big T]

Benno: Yeah mate, i know exactly what you mean... aftermarket centre FTW. Must be a Ford type diff that has the unequal length axles then... like i said, been a while since i looked at non-toyota diff conversions.

...86... : Spares are not for sale. I know i'll need them one day so I'm keeping em for a rainy day.

Eddie.

[jontrueno]

so what's the axle number on the compliance plate thingy that i should be looking for? so this mx13 rear is good for 160kw? and i have a zenki rear and my rims sit in just right under the guard, so this mx13 is exactly the same length so the rims will still fit exact same? and the mounts just need to be converted and handbrake cable taken care of then it was sweet?and is the mx13 5/4 stud? and does mx13 = f series?
thanks boys.

[af300e]

MX13 is not the same length as an ae86 s series, but it is very close (15mm longer at 1425 including brakes).
They are 4x114.3 pcd. Just look on the firewall, diff number will be something like F392. All the mounts are wrong, use your s series mounts, build a jug to keep them straight during welding and try not to put too much heat into it. Use st141 live axle backing plates, discs, calipers, hard brake line, handbrake cables (modified) and you'll need a ring on each side (approx 2.5-3 mm thick) to keep pressure on the bearings as the disc backing plate is thicker.
Then get an lsd into it and you are set.

For street use, can't go past a Tru-trak centre for it. Dirt cheap compared to clutch pack types and need very little servicing as they're a torsen centre.

af300e: We'll just agree to disagree :) I'm still measuring less than 1425 on all 3 of my diffs here. The one in my sprinter atm measures 1416 with disks + brembos. The 1410 i measured earlier was axle to axle without drums. Perhaps the difference is due to our brake setups. Either way, MX13 diffs are probably THE best doner diff in terms of weight, strength, stud pattern and width. Pity they're getting harder and harder to find these days.

[af300e]

I've had a truetrac set up in my banjo to go behind a gen3 3sgte (180kw). I haven't driven it yet, but I don't expect it to have any issues.
Eddie, I measured mine as 1295mm from face to face of the housing, 1415 from hub face to face and the discs (st141 rears) are 5 mm thick. That gives me 1425. I'm happy to disagree though. :)
Weight of the F series is excellent, I think i measured the housing including banjo as 45kg? I don't exaclty remember. Probably 6-8kg heavier than a T series but also twice as strong and definately lighter than g series. The axles make the t series ones look like toothpicks and they are 27 spline vs 23 spline.
Also, ADM t series axles are the same as s series except for the bearing size and overal length so the only benefit in an upgrade from s to t is the availability of limited slip centres. Basically, if you snap an s series axle, you'll snap a t series.

F series all the way.

[riceburner]

What lsd fits into tarago diffs, then.

Ive done alittle searching and I'm finding mixed responses.

[af300e]

Depends. I'm not 100% sure, but i believe that some taragos run an E series, whilst others run an F series.
F series will take an lsd from ma61 (for sure), 4runner front?, Altezza?.
E series lsd's are tricky, perhaps a rear centre from a GT4.

I can't guarantee any of these except the ma61 centre into a f series live axle, so do your research.
