So I have a 87 t2, and I was considering rebuilding my lsd.

from http://www.mazdatrix.com/G8LSD.HTM I noticed they sell 2 types of clutch lsd rebuild kits for turbo differentials.

One just uses 4 clutches that toal a lil more than 200 after tax.

The other lsd uses 2 inner and 6 outter clutches which adds up almost 400 dollars.

Do I have this right? One CLSD uses 8 total clutches and the other uses 4?

Which is better, the one with more clutches , right?

Where can I get new bearings for my diff, besides the dealer

 

You need all of them, 12 in total. Look in the FSM.

 

holy **** your better off just getting a kaazz LSD if thats the case

 

$566 for plates or $1093 for the Kaaz...

IMO unless you're making a lot of power or you're a drift dork, an FD Torsen diff for a couple of hundred bucks is a way better idea for a street TII.

 

^ Agreed. Torsens are so much more practical in daily aplications and most race scenarios minus drifting and drag racing.

 

Drifting isn't racing...

 

Agreed. Drifting is Figure Skating in cars.

What tests have you done to know your LSD is shot?

 

Im in so-cal and I'll sell you a torsen for $225

 

I just installed a Kaaz 1.5 way and it was around $850 to my door from Kaazusa. I don't think I would recommend it for alot of people for street use. Even after doing the break in procedure and driving around town for the last couple of days the clunking, groaning, snaps, pops can get a little annoying going slow around tight turns or even just backing up and parking. I don't mind it though, but I do have to relearn how to drive this thing.

 

They DO have figure skating as an Olympic event...
So you're saying it can't be a competitive sport?

Sorry, I just couldn't resist.

dont they make a kaazz rear for street use thats supposed to be not as loud and more streetable?

 

So a fd lsd would fit in my s5 vert turbo? Thanks

 

if you have a TII rearend installed.

 

i always thought that the 87 TII diff was the strongest out of a the gens

 

There is usually no need to buy all the clutches. The FSM has the procedure to tear apart the diff, as well as tolerances for the plates, clutches, and washers.
Mazdatrix, Mazda Motorsports, or any dealer can get you the bearings.

 

Start from the beginning........are you just getting an urge to rebuild your diff, or is it worn out? S4 TII diff's are some of the best around, and depending on the mileage, how it's been driven, maintaned, etc, it may not need rebuilding and you could put that money somewhere else in your car.

Sometimes if it does need to be rebuilt, one or two discs may do the trick, you have to remove the parts, measure, and order new ones accordingly.

I have seen plenty of people think they have problems with there LSD's when the case was only wrong fluid was used. Sometimes a good quality friction modifier can help a clutch type LSD with some high quality fluid.

 

The S4 (not just 87) diff is the strongest, but that doesn't make it the best. The FD Torsen diff has the best action for a street car, and unless you have a high-powered engine and like doing clutch dumps (i.e. drag racing) you're not going to break it. Plus they're cheaper than a rebuild.

 

Just to add, different types of differentials (S4 = clutch-type, S5 = viscous, S6-S8 & JDM Infini S5 = Torsen) put the power to the ground different ways. If you're only going in a straight-line, the clutch-type will be the most beneficial, but if you're going around a corner, and your wheels never leave the ground, the torsen generally provides the smoothest delivery throughout the corner as you put your foot down.

 

would a torsen be an upgrade from a s4 t2 clutch type for a drifter?

 

No, drifting set-ups benefit more from a clutch-type than a torsen, but you can drift with a torsen as well, it's just easier to get the back out under power with a clutch-type.

 

Wow, this diff rebuild is costing a lot. Ive seen other cars' lsd rebuilds and it costs a lot less, but I guess they use less clutches, and probably arent as good of a design.
