T series diff...

....again!
ok.. i bet a few ppl have looked at doing diff swaps into their AE86 before so they might be able to throw me some idea's.
i dont want a hilux as its too heavy.
basically i am able to get a TRD AE86 lsd for cheap enough to make it worth while.. but i have no rear end to bolt it into and no gear sets to bolt it onto!
i was thinking about fitting the T18 diff into the 86, fitting the LSD into this. and then before it goes into the car.. modifying the drums to disk brakes...
this is just one idea...
anyone else got any others?

How much power is it going to have to hold?
Might be better off with an F series rather than the T series.
From what I've heard around here, for an F series rear end, you'll be looking for MS112, RT14x, or Corona MkII rear end.

its behind a mildly modded 4age so not a lot of power.
it will be driven hard tho, few track days, drifts that sort of thing.
F series.. they come in an LSD and live axle?

Yes, there are F series live axles which will accept an F series LSD centre. It's probably overkill for a puny 4A though! 
A T18 diff is probably the go; chances are it will either bolt right in or be fairly close. Get your measuring tape out and go nuts!

Yeah, stick with the T series. No point in going to all the trouble fitting an F series if it's just a 4A-GE.

Most (if not all) F series live rear ends here in Australia are single spinners. You can make an MA61 F series LSD fit. There are a couple of other aftermarket LSD options available (TRD - looks to be discontiniued on their catalogue, TruTrac Torsen - there were some pics of this only a week or 2 ago).
That said for your 4AGE, I'd honestly have thought the T series would be adequate. A friend of mine runs a T series LSD in his 4AGE KE25 track car. No problems after 2 years.
Important: Make sure you baffle the innards so oil doesn't slosh away under hard cornering - this kills the bearings and after one track day, it'll be moaning like a two dollar whore.

I haven't done it but I'd imagine it would be very easy - a simple matter of modifying some backing plates. I think "ddeane" has done this to a Corona Mk2 diff - the same principles apply. He has written a nice article - it is in the tech sections.

I know there's a difference in the actual T series axles, there was early and late. Later ones were upgraded by a millimetre or so from what i can see in the pictures.
http://www.club4ag.com/faq%20and%20tech_pages/FAQ. html
But knowing toyota the T-18 one will have probably been carried over to the AE86, hence why it was uprated later in the model run. If you are getting the T-18 diff, grab the rear section of the tail shaft too, as the S-series diff has a shorter snout and the tailshaft is too long.
I've got another idea, apparently MA45 F-series disc brake rear end bolts into a AE86. But being rare in Australia why not convert a RA60 F-series live axle to disc. Since you are planing to adapt discs to a axle. Then the trutrac lsd goes in and you also get to select any one of the mental hilux ratios availble.
5.1:1 LSD with 7.5 inch ring gear.
But this is just an idea as i've never measured anything up myself. Anyone care to do the sums on this? It's rainy in melbourne at the moment and i don't feel like lying in puddles.

Live-axle RA60's have T series diffs. F series is only found in IRS RA65's.

MA45 = M-EU, T series, Disc brake rear
MA46 = 4M-EU, F series, Disc brake rear, LSD VERY RARE
MA47 = 5M-E, USA only, F series, Disc brake rear, LSD standard (was option not to have it apparently LSD on snow/ice is a bit too much fun over there) Leather interior, Digital tuner radio, EQ and AMP, optional sports pack with firmer suspension, front and rear spoilers, inch lower... ohhh ohhhhh ohhhh.... i need some quite time alone...........
Ahhhhhhh
Yes i would like an MA47!

T series is a direct bolt up, there are many options for disc brakes which will fit, most vehicles that have the same PCD and rear discs can be adapted, obviously some are easier than others. some axles will not suit the LSD as they are too long to fit all the way into the housing with the LSD centre.
