Diff Conversion for AE71

heya guys, new to this site and to corolla's or toyota's in general for that matter
I'm about to stick a 4AGZE into my AE71 daily driver
but the diff is getting a little noisy so I figure I may as well upgrade the diff before doing the conversion
are there any straight bolt up diffs for an AE71 station wagon that are stronger than standard? .... if not, what's the easiest diff conversion that will handle a 'spiritedly' driven stock 4AGZE?
thanks in advance
Dave

AE86 will bolt in and if you find the right one you'll get rear discs and an lsd. good diff's as long as you're not going insane with horsepower. don't know about Aussie but they're fairly hard to find in nz and fairly expensive when you do find them

Few minor points I thought I might add:
AE71 wagon/panel van has got leaf springs at the back, therefore an AE86 rear end WON'T bolt in! Good news is that leaf springs make siff conversions generally pretty easy...
T-type (ae86) LSD's are generally unreasonably overpriced, hard to find and weak as piss anyway. Leave them for those that insist on them...
I'd suggest you start looking at diff conversions, which can mean anything from Hilux, Bogwarmer(commodore/falcon/R31 skyline), Nissan stuff (there's a few options there) or whatever else takes your fancy!
I guess the most relevant question to ask is, how much can you afford to spend

mrshin is right no sprinter diff would fit. I have an AE71 and I put in a Panel van diff, its normally heaps stronger than the factory glass one and its also a 4.1 instead of a 3.9 ratio by memory. You can get the right tailshaft to suit, I just had the joke machined as it was pretty close.

I am going to see how I go with just doing the disposable gearbox method. T50s are so easy to change (relativly speaking) and pretty cheap too so I think I will break a few before I think about doing somehting about it.

Just suggesting that you might want to do something about it FIRST. Yes, T50s are easy to change, but once you break a few, you'll have all the little I-love-Toyota gimps after you with fangs out Besides, it'll cost just as much to do something about it NOW as it will LATER

yeah their a bit funny like that! I sure am glad they dont mind too much about the standard AE71 diffs of else I would be in their black book! I will need number 6 soon...
I have a spare T50 I bought for $50 I will see how long I can run with my current one and my spare then I will consider my options. As far I know the only option is a Supra box with a very dodjy dellows kit, not something I really want to do.
mrshin do you think its possible to make a T50 last if theres no clutch dumps in an 86 with a 4AGTE making over 150Kw?

Well, I had a 4AG that was, at the time, only making 140 at the wheels, and I'd been trying to treat the box with reasonable kindness, but it only took a few weeks for all the teeth to disappear off of 2nd gear. As for using a W box, that's what I'm doing. I'm using the DellHousing(!), and after much brutal agression, have pretty much worked out all the issues with the bugger of a thing, including discovering one advantage - I can mount my starter on the intake side! Whereabouts you live? Mines out on the floor at the moment, you're welcome to come take a look sometime..

mine broke after about 2weeks with locked centre and a 4age infront of it. if you keep it a single spinner it shouldnt brake dont quote me on that tho.
