T Series Diffs- Info Reqd
|

Been looking at obtaining a T series for my AE-86. To cut a long story short, I can get:
RA-60, T-18 shape? drum brake, T312 (3.909:1, 2 pinion) 1425mm face to face (I think)
MA-45? DISC BRAKE! T312, also 1425mm face to face.
Current diff- S314, 1405mm face to face.
I was told the T-18 diff is bolt in. This is what I can find. Does anyone know if the disc brake diff will bolt in? Any ideas if the driveshaft will fit?

Sorry, I'm a little slow tonight, can you spell this out for me?
The disc brake diff & driveshaft are off a MA-45. Is it going to fit?

not sure about the ma45, the mounting points may be different for the trailing arms and stuff.
I know for sure that the t18 bolts in.

MA45 is an F-series isn't it? You'll need to swap your mounting points from your current rear end onto the MA45 one.
Some info in here may help. Or it may not... 
It's about getting a bigger diff to replace a live-rear T-series...

Nope. MA-45 with T series diff. and I SAW the (I think it was) 4M when I checked the compliance plate. Used to have a W50 in it, only someone had already taken it.

wraith i would just go with the t18 diff. Its much cheaper and theres no fucking around needed to get it in. Everything bolts up!
Then all you need is a nice 2nd hand 2way lsd.
have fun

OK, heres the go-
I want discs. The MA-45 diff APPEARS to have the mounts in the same place, he wants $150 for it. I measured the track, seems to be about 20mm wider, not a problem for me. Have a friend who can weld, so I might buy it anyway. I don't have a T-18 diff at my disposal- the next best thing is the RA-60 diff. Which probably will have the same problems, right? Tell me what you want off the MA-45 and I'll see if its there. Be aware it's been sitting around for about a year. Replies will be required tonight sometime though..... PLEASE!!!!

the MA45 diff mounting points are marginally wider than the AE86/TE71, but it's the panhard rod that causes the problem as the diff will be offset to the drivers side. the axle splines are the same as the TE71/early AE86, as are the heads. the axles are marginally longer than the TE/AE unit(7mm- ish).the driveshaft flange is the same as a TT132/141 Corona and depending on the age of the T-50 this is the drivehaft to use without getting one made.

Interesting you mention the panhard offset, as I've lowered the vehicle an inch or so, which SHOULD push it passenger way a little bit. I sourced a T series tailshaft today & intend to try fit the diff soon, as my S series shat a bearing around 250kms from home- gotta love RAC roadside assist. I'll keep you posted as how bad it goes.

Or discs for that matter. I'm going to modify my existing panhard (read- cut & weld a bit in), is this a really bad idea? It'll be tempory until I get an adjustable rod.

wraith, why don't you make your top mount adjustable by way of a plate either side and a series of holes. that way you could change the ride height and just shift the top panhard bolt a hole either direction to get the diff centred.

The alternative option was to drill a second hole in the top mount, sort of like what you suggest. I don't know how much pressure the panhard will produce on the bracket, I wouldn't want to break something on the chassis. I'll go and have another look in a sec. Any which way, I'm going to fit this bitch.

Just finished mounting this thing, very tired  . Everything lines up except the panhard (cut, going to weld a sleeve on it to make it.... 37mm longer, or something). T series driveshaft fits nice. Bled brakes. Getting rubber on 16" tomorrow, as 13's won't clear calipers. Fabricating handbrake thingy as stocker won't work (read- welding both thingys together). Brakes seem to work. Might make a bit of a walkthrough titled "how to fit a nonstandard T series diff to an AE-86- No mechanical experience required." Or not. Will now go sleep.
