What is LSD? Options

[silverceli09]

what are you referring to when you talk about installing LSD in your tranny? what is it?

[GotToyota]

It's a drug.

LSD= Greatness

LSD means Limited Slip Differential.

For example the stock 5sfe Celica GT transmission utilizes the S54 OPEN Differential trans. No LSD.

Eventhough if you take a peak inside the diff where the axles pop into there is a bar running through the middle of it just like the E153 VLSD trans, the s54 isnt lsd.

VLSD what I've got means Viscous Limited Slip Differential. The difference between mine is that the Viscous uses liquids to get the LSD to work, which means it is less aggressive compared to a clutch type lsd.

Basically when one wheel spins the other picks up the slack.

how did i know someone was gonna say that? lol...but seriously, when talking transmissions, what is it?

[samir0189]

limited slip differential. It prevents "one wheel" power. In a tranny without lsd, if you spin the wheels, only one side will really do most the spinning. LSD detects wheel spin and puts power to both drive wheels, instead of one.

[silverceli09]

ohhhhhh...i see...thanks

[97celiman]

yes but is it possible to "install" LSD in a transmission or does it pretty much have to come with it (the trans)
also is the e153 w/lsd bolt up to 5s?

[bccentaur3]

You can by a differential to put inside the trans. Easy IMO. Yes the e153 bolts on, but you'll need hybrid axles to run it on our cars.

[97celiman]

so you could have a s54 with lsd...has anyone with a 5sfte done this or have lsd?

came in standard SS-III (98+ or earlier version aswell?) gearbox, TRD also make a machnical one which is available for non SS suspension (helycal L.S.D.)

[bccentaur3]

I forgot who, but someone used the mr2 spyder's differential in their s54.

[bslik]

i was told that my car has lsd when i bought it n i thought he was mistaking. is there any way i could make sure? do i have to go drive through a lake and see if i hydroplane?

hydroplaning has nothing to do with lsd. One way you can tell is put your car in neutral and jack your car up and have both tires off the ground. Spin one tire and see if the other tire spins the same direction as the one you are spining. If it spins the same way it has lsd. If it spins opposite it doesnt.

[playr158]

^ that does not always hold true

[bccentaur3]

Yeah I know, but its one way you can kind of tell.

[Supersprynt]

It's totally unreliable. That's no way to determine whether you have LSD or not.

[bccentaur3]

okay fine. Pull your axles and peak in there. With the stock s54 trans you will see a bar runnning through the diff. That means you don't have lsd. If you peak through it and the bar is removed and you can totally see through it, you might have an after market lsd. If you have an e153 trans and you see a bar running through it you have lsd. VLSD.

It doesn't, it just shows how I feel about such a common-sense question being asked.

do a sweet burn out and if you leave 2 rubber marks, you have lsd, if theres only 1 rubber mark, you dont hahaha

Thats's what I always thought too lol

If you life in a cold climate its pretty easy you put 1 tire on ice and the other on pavement...and see what happen.

[soulshadow]

A lot of cars don't have LSD, especially FWD because they don't produce enough power required to have an LSD.
Now a lot of sportier cars have them, because they costed more to produce and came in very few numbers such as a Honda Civic SI..ect.
Only way to really find out, Jack up the front of the car and have a buddy look at the wheels when you put it into 1st gear and slowly let it loose.

[BonzaiCelica]

so i plan on doing a beams swap later on. But i saw how there is a beams engine with lsd on ebay. By chance would you be able to use that lsd on a gt celica??? or would it be too much to do.

[bccentaur3]

It the swap came with axles you don't really have much to do. Straight drop in.

that is not always true.
this is my wifeys car (before the color change!) no LSD here.

alright then thanks for your replys

true also we'd get a lot more understeer

[97celiman]

ok so what about quaife...is there a quaife application for the s54 or would you need a whole new tranny (assuming you had a 3s or 5sfte or basically anything putting out 170hp and up ex. mini cooper s

scratch that just answered my own question...no

so what trans that would mate to a 5s (assume it would be correctly t/c or s/c putting out at least 180) that would have lsd? the e153? these were the only toyotas on the website that quaife does
Toyota 2000 Corolla GT-S AE92 MR2(non Turbo) 6-speed QDF15E
Toyota MR2 (turbo) QDF17E
Toyota Scion E350 QDF25E
Toyota SR5 QDF26E
Toyota Starlet AE92 turbo QDF16E

and

Lotus Elise S2 / Toyota Celica / MR2 Spyder (6-speed) QDF21E

that had a quaife application

If your car is jacked up in the front and you step on the gas, only one wheel will spin, correct? So if you use like a crowbar or something against the tire to stop it from spinning (we're not talking high revs here), if you have LSD then the other wheel will start to spin. Isn't that true? It was with my 4Runner - reer wheel spun and when stopped, power transferred to the opposite side front wheel. (It was RW-4WD automatic but only went into 4WD when you pushed a button inside)

[KAOS]

I thought the Canadian GT-S models had LSD... no?
