If you were to install one of these on a TT auto with open diff, would you need to install any method of diff cooling to go along with it? :conf:

 

I think if you did TRD would specify/supply a diff cooler but they don't. They do particular oil for it though see here

This the same thing????

 

TRD Limited Slip Differential for 1993-98 Supra TT Auto & All Supra N/A

ITEM # TR 41301-JS401

Upgrade your LSD with this piece from TRD. Does not include carrier bearings, those may be purchased seperately for about $40 each.

MSRP $875.00 Your Price $831.80

 

Just re-read the TRD website and this is what (I think) it says are the part numbers for each model, (see attached screen shot):

 

41301-JA800:

93-96 JZA80 TT 6spd Manual

 

41301-JS401:

97-98 JZA80 All models

93-96 JZA80 Auto (needs new drive shafts)

93-96 JZA80 NA (needs new drive shafts)

 

Is that how others read it?

Guys The A style diff is the small diff. Buy the TRD Auto diff from the USA. The B style is the large one,, so buy the 6 speed diff from the US.

All 6 speeds have B type except the VVTi which is A

All Auto's have the A type except the UK's which AFAIK are B type.

An open diff can be changed to LSD this way.

 

We can supply & fit these diffs a very reasonable rates :thumbs:

Manuals?? If so they may have used the facelift change over to install A diffs on the manuals.

is the open Diff the non LSD version like on my jap auto (1 wheel burnouts)

 

i have the uk lsd in now but it did not drop straight in, had to have a bracket moved from what i can remember it was about 1" or so too big.

 

confusing.

 

the powerhouse racing still use the stock lsd in there race car.

 

how much of an improvemen is going from a stock lsd car to a trd lsd

can you notice a big difference?

for what drag racing??

 

I like it but then I always loved MK2 Escorts with plate LSD's. There is less slip, but it makes the car a handful in the wet. In the dry in theory it has more traction, but it doesnt help on launches believe me.

No Cosmic, a TT Soarer with open diff to the TRD. Oh, and I have a direct comparison to the Torsen in the TT Supra. The TRD is better, simple as that, though of course the difference v Torsen is smaller than difference v an open diff.

 

Yes, there is a TRD diff for auto Supras/Soarers. My Soarer is an auto.

 

It is more snappy, I have not tried in proper wet weather, but in the damp I definately agree with Terry. Though as long as you bear it in mind, it is nothing to worry about.

 

 

i daily drive a BMW M3 (E36) and a BMW M5 (E39). They both have clutch type LSD (same type as TRD) which is 25% locking. And i obviously own a TT supra with the torsen... well... i *definately* like better the torsen in track curse. much more smooth when the traction is to the limit and the back begins to swing out. I rekon the BMW have slight better straight-line traction, but as soon as you encounter corners the supra end becomes much more predictable, i definately love the torsen :)
