LSD for T-series axle
|

I believe that a TA22 Celica from the factory uses a T series rear end. Can anyone confirm this?
If this is in fact the case, will a T series limited slip differential centre fit the standard differential housing?
It seems these differentials are common in JDM AE86 rear ends.

Yes, TA22 had the T series. Very few did have the D series, check your compliance plate. You will most likely have a number like T312 with the T relating to the series.
AE86 T series will fit the standard housing. Only thing is that the shafts need about 5 mm cut off each end to give enough clearance for the LSD.
Cheers,
Simon

My compliance plate does not specify a transaxle/differential code. It's a 12/71 compliance, so one of the earliest TA22s to land here. Is there a correllation between build date and differential type ~ ie. earlier cars with D-type?

Paint will be finished over the next few weeks.
After that I've got to handle the suspension refit too. I can see budgetary constraints being more limiting than time constraints there, as I need about $1K of new parts.
Then comes rego.

on my '75 22, the trans/axle code is T50 T292 0-4.
don't know if this will be much help, but it is a later build TA22.

Yes the earlier TA22's had the D series diff, so chances are you have one.

Is there any way to tell the difference between D and T diffenentials when installed?
What level of interchangability could I expect between the differentials? A smaller R&P size for the D diff would I presume require unique driveshafts, but presumably the tailshaft flange is the same. The hubs should be interchangable. The housing, if not the same, should share layouts with the T housing.
Surely I could just swap out the D diff for a T diff, yes?

I think you will find that the D and T series hosuings are not the same. Measure the PCD of the bolt holes from your current diff centre and then go and measure one at a wreckers and see if it the same. Check one that has T*** on the compliance plate.
Worst case, buy a T series from an early TA22. they are cheap as.

I have an ra23 T series diff you can have if you want to pull it out of the car!

This was sort of the way I was heading. The tailshaft flange will be the same I presume.

the T292 diff was used all the way through to the end of the RA40's and possibly into the ra60's aswell... Ive had 78 and 81 ra40's and 76 ra23 and a mate has a 74 ta22 all with t292's. As far as im aware, the standard ratios are 4.1 for manual and 3.7 for auto.. tho that may not be entirely accurate. I will be checking one from a 5 speed RA40.
Where would I be able to get the LSD centre readily?? I would like to get it from as far north along the east coast as possible.

TA22 and RA23 auto's came with a 3.9:1 ratio; not sure about later models.

The driveshaft flanges on RA diffs are slightly different to TA diffs, check this before you get too far - take your tailshaft to check the donor diff.
