i have a 95 4 lug, changing to 5 lug, and its not LSD. Do any 240s have LSDs stock? and if so what years? i dont want older ones with higher mileage, but how do i find out which ones have LSDs 95 and up. thanks

welp, most of the cars I see that could have one are usually higher mileage and the VLSD is probably wearing out by that time.....

91-93 240sx SUPER HICAS edition
s14 SE with LSD, not all s14 se's had lsd's......... the best way to tell is to identify the differential housing on suspected car.

I keep confusing my self on this, lsd = limited slip differential, better for handling (onramps and such) because the wheels can spin and different speeds, not as good for say drag racing because 1 tire breaks traction and not the other one so your launch is crummy and your burnouts look funny.

Right or wrong?

The primary alternitive to this would be a locked differential, positraction (thats a gm brand name or something?) These would be more useful for the strip, but not as desirable for the average daily driver?

VLSD is something of a compromise of the two?

If that's all correct, all, (or most of) 240's (usdm) came with LSD's? and the usual swap is to put in a VLSD to get a better launch.

I'm sick of one wheel peel outs my self so some one straiten me out on which one is which. =(

open differential is when it is crummy for drag and allows the other wheel to spin slower than the other. A lsd allows both wheels to spin evenly. there are many types of lsd: clutch, helical, and vlsd. Clutch is the 1.5 way, 2 way or 1 way. Helical is the lsd found in s15s and quafie(i know that isn't spelled right lol) makes helicals. VLSD is viscous lsd. when the internals of the lsd get hot, it will expand and lock. that is difference where clutch would grab like a clutch. LSD between 91-93 only came with lsd(the s13 models) and they only came in hicas. The 95 and up models were an optional package and there isn't a sure model that have them. You would have to find the orange sticker or spin your wheels. Lsd will help with better traction cause two wheels will spin at all times instead of one like the open differential. Hope that helps

Vsiev is right, and its the 240SX SE models that came with 5-lugs and a VSLD, found out that from the dealer. Anyway, the reason I like Nissans is the options are almost limitless, you can also get the LSD from a Z32, Infinity J30, Q45, Skylines, etc. But to be sure, find the orange sticker.
Oh and the good thing about Viscous LSD is that, even after high mileage, it is the fluid that suffers the MOST wear and tear, unlike clutch type which, your clutch packs/discs get worn out. Usually, VLSD are godd for past 150K, just change the fluid, and they are good to go, they rely on fluid expansion as the locking mechanism, but that don't mean the internals will last forever though.
But don't get me wrong, even if they are long lasting, they aren't the best for certain types of racing, VLSD have a down side to them, if you are continuosly locking them up lets say in drifting, the fluid stays hot, and stays locked till it cools down (hence why you see some Japan racers with VLSD having differential coolers) I know many drifters use the quafi, it is more suitable for drifting.
Someone correct me if I'm wrong, long time since I read on this.

actually hardly any use a quaife, they all use clutch type diff's........

quaife's aren't good for drifting, they act more like an open differential as much as possible, they aren't really good for drag racing either, they are best suited for grip road course type racing.......

where as a clutch type diff locks and kicks the rear end out easier, you can also adjust the lock-up to be more severe, for say like a drift only car like the Drifter X or Signal Twins... clutch type diffs are better for drag racing or drifting, almost ALL jdm aftermarket lsd's are clutch type, as well as the NISMO diffs.......

Just about all nissans that are RWD use the "R200", Skylines, Q45, J30, M30, 300zx, 240z, 240sx, etc....
r200 is the type of differeneital you have... but they are all a little different, mainly the output shafts or wether or not the car has ABS.

I think if you really want to get a LSD, just buy a new aftermarket one, and have it installed in the differential housing already in your car, if you get the whole setup from another car, like a 300zx or j30 swap, you have to get other parts to make it work..... and its still used

the actual wheel locking mechanisms that make it a LSD can fail so its like an open differential, but the actual diff can go bad as well and lock up or blow up..... buy a new one IMHO

by him asking which other cars have it, I gathered that he didn't have enough cash and was going the used route, anyway, if you have enough cash, SR is right, get a new one, but if broke, get one from the J-yard for around $150, pull a part GA $50 bucks if they have them.
I thought Quafie was the name of the company, or is it the type of diff??????????????????

are lsd's universal??? can i find one from a different nissan car and fit it into my 96 240??? i have a 96 4lug, no lsd, looking for one to put in, but not sure which is which, and can i just find one and put it in my car??? thanks.

You can use the one off a S14 SE, 300ZX, J30 or Q45, the diffrence is usually if the car has ABS or not, and also the gearing, don't get the Z32 TT diff unless you got +300hp, the gearing is diff. other than the J30 and S14 SE diffs, all the others you have to change the LSD out puts, nothing too hard, but you going to need a strong prybar.

not all s14 se have vlsd. Don't assume just cause it is an se it has vlsd. There is no guarantee in knowing about the s14 unless you crack open the differential or find the vlsd sticker. You can try spinning the wheels which is not a guarantee test but will help determine if they have lsd. Also quafie is a brand name lsd maker. They are helicals lsd like the ones found in s15 which is good if you do auto x.

you can't really just throw in a LSD mechanism from another car, you can but its a lot of work, just like installing a new one... something a skilled technician in that field should do.....

now you can swap in units, this would replace the entire pumpkin housing etc...



Quaife is a company, their differentals are badass for grip racing, they are a lot more money, but its worth it. They also carry a lifetime gurantee no questions asked... I think I have heard of one person breaking one in a SHO Taurus on the race track.. it was replaced no questions asked.... but all the other forum members had some questions lol... they wondered what the F he did to break that beast....

I replaced the LSD in my 240 my self, you can do it with a decent set of hand tools, jack stands and an extra set of hands. I managed to swap it by myself, but not before crushing my hand with it, but it was all in a days work. It is really self explanatory, I can give you the steps, but once you get down there you will be able to see what you need to do.

I might be wrong but don't Manual and auto trans S14's have different gearing even if they are both VLSD?

I have manual so I was told to swap one off a manual if I am going the used route.
