MKII Corona DIff Advice

[OMR510]

I am able to get a MKII Corona diff for my AE86 fairly cheap and locally and I need some advice.

I know its an F series and the width is the same as my T series and ithas bigger drums ?

Firstly I have read they are bolt in no mods needed for an AE86, is this correct or do the spring seats and control arm brackets need to be re-located ?

Also the propshaft flange will it fit the T series prop shaft ??

Will the T series tailshaft fit or do I need a custom one for it ?

The same seller has a Torsen style LSD for it as well he wants to sell.

Pros and cons of the torsen in relation to drifting as I have a Kaaz 2way in my Tseries and I am quite happy with the way it works.

Also I have used the search option both here and on Google before someone decides to point out the obvious
but it must be the way I look for stuff as all I find is a lot of dead threads with no real helpful advice.

So your help will be much appreciated so I can decide whether or to buy this diff and use it.

Thanks Keith

The F series will not bolt up to a AE86 platform. You will need to have mounts changed over....

You will need another or modified tailshaft.

Double check it's an F series too. Alot of the MK2's were actually E seires

torsen lsd's are crap for drifting.

I've got a kaaz in my f series and its really good, taken awhile to break in though.

Care to elaborate on this statement? Explain why a geared LSD is "crap for drifting"?

[Jip86]

The term Torsen comes from TORque-SENsing. It's designed to apply equal pressure to both wheels in a straight line and direct torque to the outside wheel in a turn. They require some kind of force acting against both wheels in order to work properly, though. A lightly loaded inside wheel in a turn still has some force working against it, which allows the torsen to work as designed. But, if you lift that inside wheel completely, the torsen is out of it's element and will actually spin that lifted wheel just like an open diff. Torsen diffs continually vary the load from one wheel to the other to promote the most grip. It makes them unpredictable.

They do design Torsens with a pre-load built into them to get rid of the wheel in the air problem. I have found them to be a great LSD option that has virtually no wear (as long as you change out the oil regularly). The times it has been on the skidpan, the lsd performed flawlessly. My previous diff had a TRD 2 way and I find the torsen very similar, if not smoother in operation. That said, I don't take my car drifting every weekend so perhaps other people have differing opinions.

What car and diff Eddie?

[Big T]

Car is an ae86 with a mk2 F-series. The car previously had a jdm T-series with a TRD 2 way.

I have had no experience with Torsen diffs, but if Lindsay is right with this description, they sound absolutly terrible.......
