LSD Gearbox?

[AceSniper]

haha you will needa do some testing or look in the axle hole as I think things are abit over the place in this post, As my car is currently runing a box off a 96 s/s no lsd, if anything its a factory option, its more likley people who payed xtra for s/s would also get the lsd

[sergei]

BZ-R gearbox has TORSEN lsd. We had it apart and unit is not sealed (as in: there are holes for oil to get into). Viscous units are sealed (e.g. center diff on ST185/ST205). Also torsen LSD behaves like an open diff when 1 wheel is in air. While viscous is resisting with one wheel in the air (Proved by trying to turn one front wheel in the air GT4 with all other on the ground - it resists, a lot. Also if handbrake is on and car (ST205 gearbox) is in air, in gear it will try to stall if clutch is released) .

ok torsen

BUT i am 110% certain that ss = lsd in the ae111s

have looked into that quite deeply wiht model numbers and trans codes etc

[sergei]

Can some one confirm that with SS BZG you cannot get only 1 wheel spin?
I'll go arround the yard at work, and see if we have any manual BZG with SS...

[Mr Revhead]

also check the trans codes

and i reread my thread here:

and reminded my self, that facelift ae111 bzg 6 speeds (ie all manual ones) are open. same diff as the 5 speed xz etc.

so....
ae111 5 speed + s/s = lsd
ae111 5 speed + non s/s = open
ae111 6 speed bzr = s/s and lsd.
ae111 6 speed bzg = s/s and non lsd
ae111 bzv and bzr = s/s and lsd

:/
if that was the case tho
like 70% of c56 gearbox's would be lsd

if only they were that easy to come by

[Mr Revhead]

well the c56 is in the late ae101 including wagons and sedans etc, and the ae111 5 speeds, also including wagons etc. the only ones with LSD are some preface lift ae111 bzgs

[4000GT]

I brought a BZR 6 speed box... no LSD in it of any kind.

[sergei]

so it was not BZR box, and you got ripped off. Thats assuming that you tried to skid and could make only 1 wheel spin...

[4000GT]

Yup possible. I had the box open, no LSD, no need to try skids.

[Crampy]

I've got an AE111 BZ-G Trueno with S/S. It definitely doesn't have an LSD. I know cause it liked to spin a wheel at the drags

[Crampy]

Oh and it's only 5 speed, not 6 speed.

[Mr Revhead]

whats the full trans code.

[IH8TEC]

this could go on forever i have a s/c mr2 lsd gearbox though

[Mr Revhead]

nah its already been explained

the only doubt i hav is weather they are viscous or helical.
coz they act like a viscous...

[Crampy]

My trans code is C56-04C.

It's on a 1995 Trueno BZ-G.

It's not an lsd.

[Mr Revhead]

c=LSD

if it hasnt got an lsd now, the box has been changed

[AceSniper]

yea keep note that the cars not new so you never know if the box has been changed... if CircuitLevin was from a bzr it may have been changed at some point.

And I can count atleast 4 people that have had a ae111 lsd box apart that all say its a helical and iv seen a helical out of a BZR

[Mr Revhead]

hmmmm
i know the basics of how a helical works, but im no expert
is it possible for them to have a gear ratio so the LSD action is quite low?
i know if they cock a wheel they are effectivly open. but its the "tightness" changeable by altering the gears inside?
