Is there a lsd diff center available for the AE71 corolla? or do i have to change the diff in my 1984 AE71 wagon to a R31 diff or something?

cheers. :hmm: i have a standard 4age 20v silvertop to install soon. :S

The standard AE71 diff is a Borg-Warner unit, and to my knowledge there isn't an LSD centre available for that particular one. The simplest solution would be to switch to an AE86 T-series diff with the LSD centre, but you'd be looking at about $1,200-1,500 for a complete assembly in good condition. An R31 diff (also a Borg-Warner but a much larger one than the standard AE71 one) would seem like overkill with just a standard 20v. I think they're cheaper than the AE86 diff, but not by as much as you'd think, as the EA Falcon and VL & VN Commodores all use the same diff, so all the Falcon and Commodore owners want them as a bolt-in LSD for their vehicles.

cheers mate, thanks for the info. It seems like allot of money to go there :S

yea it depends how hard your going to be on the diff, a t series could work with an lsd but might snap axles, you could go f series to be sure

in my opinion a t-series would be more than strong enough to cope with the power of a standard 20V

 

t-series came in local t-18 models in 2 version kouki and zenki, kouki coming in the seies 2 t-18 has slighly stronger axels than the zenki, lsd centres are available for both.

 

the t-18 version of t-series came with drum brakes that with a freshen up will be good enough for most aplications. the jap spec disk brake t-series are much more expensive, the factory centres in them will probaly be warn, parts are harder to find for them etc..

A piano might fall on your head aswell but the chances of that happening are slim.

So what we've decided, is: T series diff, and avoid concert halls and any auditoriums of musical recitation where there may be a risk of piano strike.

Yep, that seems to be the general gist of things. Except you may want to avoid musical instrument suppliers as well, just to be safe. :S

Safe.... SAFE?!?!? are you crazy? those things are even heavier than pianos!

If you have the experience to drive a silvertop to its limit then i honestly believe the t series will not last...if your going to spend the bucks on the motor why not have a bulletproof diff

20v's arent that much more powerful than a 16v.

 

as said before.........theres more chance of a piano falling from the sky whilst playing fur elise magically and landing on his head. theres heaps of people drifting ae71's with just a welded locked diff... havent heard of any of them breaking, let alone a t-series

ok you will all mouth me, but my hilux diff build up is cheaper than most of you would expect,

 

complete diff from 4 runner $51

lsd center eBay score $200

4.3 ratio crown and pinion $100

r31 disk brakes $50

 

all i need now is a mate to do the mounts, get the axles machined down and ill do the brakes myself, this should be a $200 job MAX

That is a bargain.

 

As for the strength of the standard AE71 diff, my KE55 with 4A-GZE has gone okay with the same Borg-Warner diff in it. I did break my first, but that was cause I was trying to do a burnout and the torque made the axle tramp all over the place and broke the spider gears. I now have a diff from an auto KE55 (4.3:1 ratio instead of 4.111:1) which is welded and I haven't had any issues in the 18+ months or so that I've had it in there. And remember it's torque, not power that breaks diffs and transmissions. The 4A-GZE has 200Nm vs. the 145Nm of the standard 16v's and 160Nm of the 20v's. That's a significant difference.

I know a guy with a JDM 4age ke70 running a stock welded borg warner and he is skilled drifter, Torque snaps axles and breaks centres, But it depends whether your a clutch kicker or use the cars wieght.

hey mate put in an S series you will never look back ;)
