i dont wana trip on lsd

[whereda40at]

can some one please explane to me exctatly what lsd does and what the diff. slips mean.

i think i need lsd on my car but dont no. i do 1/4 mile trags and am on 275 drag radials and cant get my 60 ft. under a 1.9. i have an sr20 with 320whp and gettin my greddy intake manifold, 800cc injectors, and q45 mafs and boost turned up to 1.2 bar from .9

i realy need to brings my 60 foot times down.

thanks in advance

what the ***k.....

[slothonaleash]

limited slip differentials lock the wheels so that they both spin at the same speed, as opposed to an open diff where if one wheel slips, all the power goes to the opposite wheel


there are 1 way, 1.5 way, and 2 way lsd's...1 way only locks under acceleration, and 2 way locks under deceleration and acceleration....1.5 way is somewhere in between

and an lsd (at least 1 way) will drastically bring your 60' times down

if you don't have any more money, you could also always weld your open differential...works the same way as a two way, but it's free...but ghetto

[Taniguchi_Is_#1]

if im asking i already searched


search harder. like google. or how things work. damnit. sentence fragment.

[whereda40at]

is it safe to weld the open diff shut. my friend was goin to do that on his jeep so that he had 4x4 all the time. but i dont have any welding skills at all. if i wanted it welded, what would i tell a shop?

[unwed_transient]

i fail to realize how you can have a 300+hp sr, 275 drag radials and have never discovered what an lsd does. simply being at the track yields so much information. you never thought to ask anyone there?

[Flipzide]

Did you even try searching "limited slip differential" on wikipedia or google? :squint:

[slothonaleash]

here's zilvia's very own resident welded differential write-up

http://www.zilvia.net/f/showthread.php?t=148130&highlight=weld+differential

and flipzide, i'm bet he tried typing lsd into every search bar he could find...he just didn't get the right lsd lol

and whereda40at, is this your daily driver, or just drag car? driving in a car with a welded differential, or lsd for that matter i guess requires a bit of a safer mindset while driving in rain or around corners... make sure you figure out your car's limits before driving it hard (not speaking from experience)

[whereda40at]

i have asked people but they put it in words i didnt understand. i had standard lsd in my mr2 turbo but that is in the transmission and is like a fwd car but backwards. im still new to 240's and sr20's. thanks for that link ill check it out.

Welding the gears on a diff is great if you have a couple more around the shop or something, and dont care about screwing that one up in about 100 miles. With a welded diff both wheels always turn at the same speed. But when you turn, 1 wheel is going slightly slower than the other. That means alot of pressure and stress on the differential, eventually just grinding the gears down to nothing. it would be great for a drag, if you had another one to use when your not racing. And I wouldnt drive on one besides at the strip just for safty reasons.

[whereda40at]

so now i have one sayin welding is good and the other says no. i will only be driving the car to the track or to go out to the local hang out to "watch racing". so i will have to make turns. there was a guy in that write up that said he has had his sence feb and is still fine.

Haha that's funny I've driven about 25,000 miles on one, without even changing the gear oil. That includes racing / drifting on track and daily driving.

I always hear people telling others not to do it because it'll :

Eat tires and kill your wallet
Break the welds and kill you
Break loose way too often and kill you
Make you spin out in a straight line and kill you
If a drop of water touches your tires, your welded diff will make your car flip upside down and burst into lightning and fire.

Yet I have NEVER seen ANY of these things occur on an S13.

Of course, I'm a drifter so my tires only last a month or two anyway.

My welds are strong, and everyone I know that has a welded diff used strong welds and none have broken despite years of abuse.

My car never breaks loose when I don't want it to. I actually thought this was a common characteristic of open diffs. It's extremely predictable and in most situations it provides UNDERSTEER not oversteer.

I drive in the rain all the time and its better than an open diff, feels like it has more traction, and its so reliable I know when and if it's going to break loose, rather than shit surprising me like an open diff.

I think that's like saying "I wouldn't drive on anything but stone tires because rubber can pop, you know, for safety reasons."

Whatever though.

you make "strong welds" sound like a product LMAO

[SexPanda]

eh, to each his own. I work in a shop and ive seen welded diffs with maybe a few hundred miles look like a bowl of metal pudding. But different people have different skills, and the way you talk i'd say your a damn good welder. And for daily driving, I still wouldnt reccomend a welded diff because of the whole "turning makes your tires turn at different speeds" thing. IMO if i was to do it, id get a professional do it for me, and go get another open diff just in case. That or Id find a wrecked 300zx and get the rear end off of that. A local junker does nothing but nissan/datsun, so i can get just about anything.

Well thats not what i was thinking... I was thinking a weld would break off and you wouldnt destroy your diff, and at most not be able to drive your car... And that would be really bad on an interstate... Like having a blown tire or something. Trucks suck i can tell you that now.

[arkive43]

lolz.......welded diff rocker checking in, what squid said is true. especially the last thing about bursting into flamez.

[yarou]

I still don't understand how the workings of an lsd have eluded this guy for so many years.

[TheSquidd]

<<<WTF???


Sorry I should clarify, those are arguments I've seen on this forum and others.

I didn't weld my own diff, I gave it to a real professional to handle. As should everyone else.

Having a welded diff ( A diff that was welded RIGHT, keep in mind ) is no more dangerous than any other modification to your car. Any modification can kill you, including different tires, after market differentials, suspension, bucket seats, brakes or wheels.

The trick is doing it RIGHT and you should be fine.

How many of you that say a welded diff is dangerous have actually driven on one?

Yes, welds CAN break and the fragment of metal CAN get stuck and lock your rear wheels, and you CAN spin out and DIE.

But you can also choke on food. So starve?

A limited slip diff in any car is still a limited slip diff. To think that an MR2 has some magically different type of locking differential than a 240SX and still not know what either one of them do is absolute stupidity.

[SexPanda]

now you guys are just loosing me. Im not a great welder, and dont know any i can actually trust around here, so i would never try it. Back to the original topid thingo though...

Check the internet, even ebay, for 240sx LSD's. Also, NISMO has an LSD. This place has them for 800. http://intensepower.com/nilisldis124.html

Go to www.car-part.com (http://www.car-part.com) and look for one too. i swear to god the have everything.

Also, check this out. This should answer any questions you have about diffs, and its pretty easy to understand. http://auto.howstuffworks.com/differential.htm

But about intensepower.com... I have never dealt with them, so I dont know how they work as far as costomer service. Just wanted to clarify that. Always do research and make sure a company is reliable before buying off them.

[johngriff]

Welded is not as noisy as a 2 way. Dont have a retard weld it. Done Deal.

[240m3srt]

If this is a daily driver i wouldnt recommend a welded diff. When you make a sharp turn one wheel will skip and make a loud chirp/clunk that will scare everyone in the parking lot and they will think you dont know how to drive.:keke:

[johngriff]

By that logic, you shouldnt put a loud catback on your car either, because everyone will think your car has a whole in its exhaust.

[SexPanda]

Well, Im used to loud catbacks, especially with all the rice around these parts, but if i heard a loud clunk or chirp from a car, id actually turn my head. thats just me...

[EJ253]

just weld it.
thats what all drag racers do.

and its fine for daily driving IMO
just be really careful in the snow.
and dont fuck around in the rain.

thats about it

[Flipzide]

Driving with a 2way LSD or Welded Diff in a parking lot makes babies cry. :)

Actually it isn't that bad, imo. Just drive like any normal person would in a parking lot and noises should be minimal.

[whereda40at]

i would to but who cares if people dont think i can drive that would help me out then cause if they wana race they would be thinking that i cant drive and its easy money.

[Leetheslacker]

we welded my friends s12 diff.
and the welds broke, but we didnt die. we were just drifting and were like hey, its open diff again wtf.
so we welded it better.
no problems with it at all now.

It's because all of you guys have 15" rims and used tires. My 17" Federals don't chirp they swish. Swish Swish Swish Swish.

Funny story, back when I had 15" rims and used cheap o tires. The Govenator, Mr. Schwarzenegger was coming to my work to make a speech. Well, being on the Audio/Visual team we were going to film it. Unfortunately we were all out of tapes for the video cameras, so me being the gopher I was sent to K-Mart down the street to go get some tapes.

As I'm leaving this parking lot, I have to make a right turn to exit the back parking lot to get to the front parking lot and then another left turn as I leave that parking lot to the street.

As I come around the first turn, leading into the front parking lot, my tires are screeeeching like a banshee, chirping like someone slamming on the brakes. I come around the corner and there's about 6 guys in black suits and shades standing in the parking lot ahead. They all instantly turn around, put one hand on their hip and one hand on their ear piece.

It was the Governor's security team, they all thought I was coming around the corner really fast and trying to hit his Hummer as it pulled into the parking lot.

Once they saw I was driving like 2 mph they relaxed but kept an eye on me as I passed.

I waved a white guy wave and yelled "Sorry! My car is crappy!"

Then I chirp chirp chirpped out of the 2nd parking lot as they kept watching me.

[whereda40at]

well i dont daily drive the car i drive it prolly 2 times a week and thats to the track and the local car hang out. i dont drive it in the snow or rain cause its not for that.

[240m3srt]

I dont like loud exhaust either, but at least it doesnt look like you are a 16 yr old stalling the car when you turn.

Do whatever ya like. But not everyone will be understanding in the grocery store parking lot with kids around.

[TheSquidd]

Sorry are you suggesting not to do something because some lady at a supermarket will think he can't drive?

[whereda40at]

my buddy had a wrx with straight cut gears in it and people always said he couldnt drive but that car was 11's all day with a few bolt ons and a 20g turbo. like i said i dont care what people think. as long as it is reliable.

what kind of shop would be the best for that.

[kevtrinh]

ur in MD, ma-motorsports can weld your diff.

[whereda40at]

i have heard they do good work. i might have to check them out. does anyone know the average cost on the work for them to pull it out and weld it?

[Phlip]

How about you google/yellowpages.com them, then call them and ask them?
Your hands have been held far too long about things you could be searching for. I am locking this before it gets any further out of hand
