hey, i jacked my 7 up the other day, and i don't know why , but i started her up, and but her in gear, had her idling in 1 with the rear wheels off the ground, only my rear left tire was spinning, but i was able to spin the other tire by hand ( not as easy as my left tire spins, but still turnable.

Oh BTW , i a 90 GXl, i wanted to put a tii rear end in because of the LSD, but my buddy told me it wouldn't fit, true or not, and hm... if not, what LSD should i get ????



thanks in advance

1 tire spins because either your car does not have an lsd or its worn out. A t2 rearend will work, but you need the entire drivetrain then.

or a modified driveline

modified driveline ????

i mean i have the only 7 around here lol , i have to explain to everybody that i don't have 4 cylinders, and then they always ask if my engine is broke, because it's only running on 2 cylinders Oo

Didnt s5 gxl come stock w/ lsd???

the s5 gxl didnt have an lsd, the miata torsen fits, form a 94+ model

to put the t2 stuff in you need the whole deal like the other guy mentioned

eh im sry my bad...

Wait so did s4 t2's come with LSD's?

mine damn sure has one...

Look for a tag on the drain bolt or fill bolt on the rear it will say "LSD" on the tag.



Another test: Jack it up and hold one tire still while you have a friend try to turn the other one, you should be fighting each other.



Another Test: Do a burnout and see if only 1 tire is peeling out.

jack up one side- see if you can turn the side thats off the ground- it shouldnt if its an LSD.

All S4 GXL's came with LSD (so did 86/87 sport models and GTU)

No S5 GXL's came with LSD (the GTU-S did)

All TII's came with LSD (S4 TII clutch type/ S5 had viscous)

damit lol, i need and want one :(

hm,.... if i wanna get a good lsd, where to go, what to buy ???



thanks fo all the replies

I would suggest looking for a 94+ Miata LSD since it is Torsen. Other than that you can use the LSD out of Series 4 GXL and GTU models. I belive that even FB/SA LSD's will bolt in.

OK I guess that sums it up, I guess I have one, I did a burnout a while back and only one wheel spun(one tire burnout). So cool thanks for the input. https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...IR#>/smile.png

hm.. i though if only one tire spins then you DON'T have an LSD

I thought It was that way.Hmmmmm.. Someone plz straiten us out.**** https://www.nopistons.com/forums/pub...#>/biggrin.png

If only 1 tire spun, then you either don't have an LSD or its broke.

if only one tire spins, no lsd



I'm slow.

the whole drive line from a 94+ miata will work in a s5??? because i need the damn drive shaft rear end and every thing haha... ****** swaps

But he said all s4 TII's came with lsd hmm mabe I should go look at that burnout mark again.

all turbo2's came lsd so if you have a turbo2 it is lsd and if only one tire is spinning you have a problem not a lack of an lsd haha so take a look at it and like jims said the easiest way is to check it and see if it says "lsd fluid only" ect

Cool thanks I guess Im gonna go try it.

All US spec TII's came with LSD. The S4's came with a clutch type LSD. When the LSD clutch packs wear out, it works like an open diff. It is very possible, even probable that your TII acts like an open diff.



Lastly two marks on the ground are not a clear cut indication whether a car has an open diff or not. I can leave two black marks on the ground and I have an open diff.

LOL!!! Hey your making things alot more diffcult, nah jk https://www.nopistons.com/forums/pub...R#>/tongue.png

still, what lsd to get if i wanna autocross / drift ???

I don't know if this will help, but my LSD didn't have any tab on it. The only difference I noticed was that on the casing, there were raised lettering, MO55 2 on the open diff, and MO55 1 on the LSD diff. When mounted on the vehicle, these markings are upside-down, I think on the passenger side of the diff casing.
