T2 rear diff in a FD, who's doing it?....
I had a Kaaz that I was planning on putting in but plans have changed so I was talking to some friends and they are recommending maybe I should try using the T2 rear because they bolt right in, its a clutch type diff, and is a little cheaper which is always a bonus. My question is who here is using this setup and what kind of results are you seeing, in terms of driveability, for the draggers out there how are they holding up to really hard launches and 60' times. Also does anyone know if it is a true 1.5 lsd or what. Any info is much appreciated so thanks in advance!!

Hehe...did the 1st one years ago
Open up the FD diff and replace it with a 87-88 Turbo II diff using FD bearings and spacers. It should drop right in with no complications.
Wish I had done mine last year before I split the casing like an eggshell. But was done after replacing the casing and it's been together for a year now with many drag launches.
Good Luck

A little off topic, but what kind of torque numbers does anyone think (or know) these differentials can handle?

It is VERY easy to install , if its new , you should buy new bearings and have them pressed on , bolt on the ring gear which fits exactly then put in the assembly with the spacers and the bearing caps just as it came out , there isn't any need to set backlash with shimms even . I did mine and the hardest thing for me was removing and replacing the diff ,since I don't have a lift at home , also the correct torque specs for the bolts are important , I couldn't find it so I just checked the bolt ratings and general torquing figures for such bolts .

>does this maintain the FD ring and pinion or do you have to switch to T2 r&p?<
YES, you reuse the the FD ring and pinion. TurboII pinion is much longer.
Only thing being replaced is the actual diff. Either replace or reuse(if good) the FD bearings on it. There's some difference between the TurboII and FD bearings.
The pinion is left alone.......Loosen and remove the bearing caps (mark the bearing caps, spacers and bearing races so everything goes back to original place). Pull the FD diff out....remove bearings from FD diff if good.... if not replace. Dop in TurboII diff with FD ring/ bearings....bearings caps.....reseal it and back in the car..

This sounds like a step backwards for FD owners...
The stock clutch-type LSD on the Zenki FC's do not last very long. Typically, the clutch plates wear out within 30k to 50k miles! Most of the stock LSD'd out there are very worn out and don't even work. There are lots of nice aftermarket alternatives out there, so why not use them? KAAZ, Cusco, OS Giken all makes very nice units...

Sorry....but if maintained they outlast the car itself.
The FC diff in my FD actually has over 80k miles and it works like a charm
1.49 60ft's on Et streets or 1.58 60ft on Nittos.....can't ask for better.

I've been in several Zenki FC's that had an average of 50k to 60k miles, and all of them had failing LSD's. I guess the ones I've been in are a little more abused.

Ted...very possible.
My Turbo II received its fair share of abuse and the diff was original......ring and pinion was a different case
The aftermarket does offer nice units mainly with abuse in mind !!!!....like you mentioned.

So what about buying a old one from a junk yard and replacing the clutchs? Are there any real good aftermarket clutchs for it or are you just screwed when they wear out?
Also, does the car feel any different with that diff in there?
