what is better a non LSD tranny with aftermarket LSD installed or a stock tranny with LSD............basicly the gt 5sfe tranny (dont know model of that tranny sry) with aftermarket LSD installed or th e153 LSD tranny

r maybe the e153 with aftermarket LSD

e153 w/lsd FTW every time.
you can install the MKIII mr2 factory option lsd into the s54 (GT) tranny, but your still stuck with the super short gearing.

[reko]

So LSD is an option on e-153?

Is there a way to know if the MR2 has the LSD ? Like, does all SW20 have LSD?

[GriffGirl]

more to the point, what motors will the e153 mate up to?

[presure2]

lsd was an option on 93+ mr2T's.
it mates to "s" series engines, griffy.

[reko]

lsd was an option on 93+ mr2T's.

I never saw a tranny with LSD. Any hints on how it looks like?

[_Jim_]

Over 80% of GEN3 Mr2's came with E153 LSD. There is a very simple way to tell if the trans has LSD if it is off the car, or the axles are out of it......there will be a "bar" going across the back of where the axles sides into the tranny. I need to pick up batteries today for the camera......so I will post pics of exactly what I am talking about later. (I am running an E153 with LSD from a GEN3 Mr2)

And Yes E153 LSD FTW!

[GriffGirl]

I figured as much, but it was worth a try

So here's my next question— these came optional on MR2Ts (OPTIONAL!? Uh, yeah, that's a no-brainer if you ask me!), okay, which means that they would need to be converted to FWD for Celi transplant use.

I did a little research and also found that these came in the v6 Camry starting in 1992 as well and purportedly can mate up to a 1mzfe - is that because it's a FWD tranny? Did they come w/LSD? I realize that motor is a completely different motor than my puny little F engine, but I'm just trying to understand how this all works. If a 3.0 1mzfe Camry came w/LSD, then it would stand to reason that that would be the tranny to be searching for, not an MR2 tranny necessarily.

[presure2]

the e153 from the camrys and solaras are non LSD, and are FWD.
just to add to what jim said earlier, the factory LSD's from e153 have the bar, non lsd e153 does not, however, the s54 trannys have the same type of bar, but are non lsd.

ok ic so the e153 has longer gears thats a plus..where will it redline at.....r would that depend on the motor

like presure said they did not have the option for LSD on camry e153... but you can insert it "TRANSMISSION:
99 Camry V6 5spd transmission w/ 95 JDM MR2 Limited Slip Differential"

[BonzaiCelica]

what can be used for beams transmission swap with gt axles? can this be used? http://www.horsepowerfreaks.com/performanc...n/Differentials

and i was doing radiator flush and fill the other day. this vid just shows how you can test if you have lsd or not... or atleast i think it does, some people said it
doesn't.

people say it caused fwd to understeer more? that true??? understeer is caused when you touch gas quickly through a sharp turn. (hmm feel like im repeating myself here. i think i said this in another lsd post) so from my understanding from horsepowerfreaks trd lsd discription. if not accelerating hard. you will have tendency to understeer.

not true at all... not even close... the e153 is not a clutch type lsd... it will only engage under load... that video is 100% false... that car could or could not have lsd... jacking it up and spinning the wheels is NOT a way to find out for an e153 with stock lsd

[Rusty]

(kind of dangerous) just jacking up one wheel or having one wheel off the ground somehow safely, if no lsd the free wheel would spin


sorry not putting much thought into it

[delusionz]

Get your mate to do a short burn out and stand about 20 meters infront to see if both wheels smoke up.

lsd doesnt create understeer, its designed to help eliminate the natural tendency of a front engine front drive car to understeer. the visible effect with lsd is when using a heavy foot around corners, the car accelerates towards where the wheels are pointed rather than towards where the car itself is pointed.

[Dragondog]

on my 5s tranny i can noticably see that it has been open and tamperd with.....i did a burn out on it to check if it has had a lsd installed b4 i bought it....i burn out dual tracks equal melted the tires on both sides and left equal burn out marks........???

that means nothing, my car also leave 2 tire marks, no LSD

I am RUNNING an E153 with LSD in my setup, BUT have had the experience of running an E153 NON-LSD on my old setup to compare to.....and I can tell you there are ZERO differences between the E153 LSD and E153 NON-LSD in the way the care feels under NORMAL driving conditions. Normal meaning just out driving, not really pushing the car.

When taking a turn and accelerating threw it WITHOUT putting any real load on the motor.....the E153 LSD feels/acts NO DIFFERENT than the same car with a NON-LSD E153.....As a matter a fact.....it feels/acts NO DIFFERENTLY than a NON-LSD S54.

Now, when you are really pushing the car is when you feel the LSD. When pushing the car in a straight line.....the car is smooth as glass, and there is ZERO torque steer, unlike NON-LSD transmissions where you really need to hold/fight the wheel when accelerating hard.

As for turning....well a NON-LSD will be able to turn "sharper" than a LSD when really pushing the car threw a turn. If I push the car threw a turn, I can feel the car want to "push/straighten out" in the opposite direction of the turn. This is because both tires are doing the same speed, when the inside wheel "should/want" to spin at a slower rate.

To clear that up.....if I am really pushing the car hard threw a sharp right hand turn, the cars wants to "push/straighten out" to the left......and opposite goes for a left hand turn.

This is not uncontrollable by any means, just takes a bit of getting used to.

[Dragondog]

ok ic...what bout driving in wet/icey conditions does the lsd help at all....?

[Rusty]

cant you use a s54 and a s53 to make a longer gear ratio?

[BonzaiCelica]

wait e153. isn't that tranny for mr2 turbo's. and when i did this video, i had car up on two jack stands and it was in nuetral.

[pittfirefighter]

LSD does not help icey/wet conditions... usually makes it a lot more difficult for the novice driver... however like said by Jim... you're are not going to notice Toyota LSD unless its a fairly high horsepower car that is being taken to redline... normal driving does not bring out the LSD characteristics... it is not a full LSD... its a 1.5... it only engages when it is needed....

Let me break it down:
When you are driving a non-LSD car... when you make a turn... the inside wheel has to spin less then the outside wheel... it has a smaller arc that it is making therefore a smaller circumference (distance)... the car automatically allows it to do this and this is called slipping.... in a Limited slip... this is taken away so that every bit of power that is used to spin the wheels is harnessed rather then letting it "slip".... anyone that has driven a 4x4 knows that if you turn the front wheels all the way and hit the gas... the wheels bind and the car jerks... that is Limited slip... the inside wheel is trying to go less then the outside wheel and it is not being allowed to do so...
now we have sports cars... so having that all the time would not be good.. so thats the 1.5... it kicks in at high RPM so that you can harness all of the power but is relaxed on low rpm so you can still make easy turns and not have your wheels bind while backing out of a parking space...

LSD will make it harder to turn at high rpm... it is trying to keep the car straight... it does not make it easier like other people have said...
and it does not always give a smooth acceleration like Jim has noticed... i punch mine and i get a skipping (walking) effect due to my shotty tires... a non LSD car would not have this problem...

ok so from i have understood after reading your excellent explanation several times. It sounds to me like LSD isn't that great. Your saying it is only meant for cars that have a high amounts of high horsepower. so it would be ideal for people who are getting 3rd gen 3sgte engines into their cars that will be only using it as a fwd format.

so i plan on swapping out a beams engine in a few years would you recommend lsd for that engine. i plan on getting lightweight flywheel, headers, cai. that should be no more than what like 25 hp. SS-III with beams comes with stock lsd right?

oh and about you saying the 1.5 trd lsd makes it easy to take turns at low speeds and backing out of parking lots. When i was at school, this 240sx tires were screeching as he was slowely turning in the parking lot, he said he had lsd. Is that considered full lsd.

I also have a friend that has a swapped integra gsr engine on his civic that has 170hp with a turbo. So it comes to around 250hp. when he takes a turn and floors it on the turn, his front tires hop across the turn. he has no lsd and accelerates just fine when he does a launch.

OK thanks for clearing things up. this stuff should be stickied. along with other information on the forums that has to do with lsd. it seems like your a pro at this stuff

Having a Viscous 1.5way LSD (thats the type of LSD installed in the GEN3 Mr2 LSD transmissions) has NO negative side affects compared to a NON-LSD tranny.

The LSD is not "activated" by rpms......its "activated" by LOAD. I cant say for sure that the LSD trans hooks up both wheels when one tires spins, as what would happen if you were on ice.....because I do not take my car out when it is icy. So I really cant comment.

As for when LSD is "needed," well that is totally dependent on the driver. It is never a "step-back" istalling LSD on your setup....It will make just about all aspects of motorspots easier. For example, you say your friend can launch his car VERY well.....Well if he had LSD, he would STILL be able to launch his car very well, but be able to do so with an added 1500-2000rpms.

As for my definition of "smooth acceleration," that is meant for 100% traction. Even a car with LSD will still experience wheel hop/chirping.....that is not to be confused with Torque steer. I meant the way the car tracks/feels when you punch the gas going 50+mph. You can literally hold the wheel with one finger because there inst any torque steer to fight. Where as a car with NON-LSD, after hitting the gas at 50+mph....there is a lot of torque steer to fight threw to keep the car straight. Of course this becomes a bigger problem as you make more power. A car making 100whp will have almost no TQ steer, where as a car with 200whp has some, and a car with 300whp has a decent amount, and so on...........

[Rusty]

yeah I sometime get Torque steer, pulls me to the right, towards the centre line.

one thing with I've heard about Viscous LSD that are JDM standard on some/most models not just toyota is that after 90,000km ish they are useless, and you have to get them rebuilt (or maybe you cant) or get a aftermarket one

[pittfirefighter]

Jim you are right about the load and not the RPMS... i use RPMS in my explanation because most only hit high rpms when under full load and it tends to make it a little easier to understand... i only hit high RPMS when i punch it so it becomes one in the same....

and just from experience.. going 100+ and accelerating in an LSD car and switching lanes is more difficult then doing the same in a non LSD car...

as for the viscous LSD... rusty you are absolutely right... they act like an open differential after usually 60-90k

[Smaay]

its the MKII MR2 that has the E153 tranny. the MKIII is the Mr2 spyder and it came with the C54 tranny attached to a 1ZZ engine. it will not bolt up to a 5S or 3S

[BonzaiCelica]

ok so i think i finally got the point of lsd. I was looking and i saw a kaaz and trd 1.5 way lsd. Like you said these types of lsd are not always engaged when normal driving but only your doing spirited or track driving.

well torque steer happens in fwd cars becuase the axles are not the same lengths. So the one axle is shorter gets more of the power and thus creates torque steer. Now if you were to install an lsd on a fwd car that has 200whp. You will still notice some torque steer even if you have lsd right?? and lsd isnt that great for taking turns since it will want to keep the car going straight. So being that i get a beams swap and i put all possible bolt ons. would it be necessary to get a lsd. Cause they are expensive!!! (hmm am i making this more complicated that it shud be?? )

So from what ive searched online. It will help accerlerate your car slightly faster in 1st and 2nd gear. It will put power to both wheels equally?
