welded diff

[chalmer240sx]

ive just started drifting my s13 and my friend welded his diff, should i?

whats the risks if there are any?

[navysnail]

not if you want to drive it on the street for long, it will tear up your tires and handle like crap, as well as putting a ton of strain on your suspention and drivetrain. It works for drifting, but thats about the extent of its usefulness. you would be much better off with a limited slip of any kind.

[martins_240sx]

Mine is welded and has been for a few months. tire wear isnt that bad, handling...It depends, you can go through turns faster, but then again you have to be careful in turns, and certain turns require you go slower. rain is not for your unexperienced driver. honestly it was one of my favorite UPGRADES ive done. just dont be dumb with it.

[dcdrift9]

How long would it take to weld the whole thing?

[1991ls13]

im looking for an all around diff, mostly drag sprint and circut, and some drift,i heard that the s15 hec is a good one?/??anyone can halp me out

[martins_240sx]

it took me about 30-45 mins

[Justin35ll]

I'm gettin mine welded soon. Should be fun

[s13gebala]

i think im gona go with a 2 way

[chalmer240sx]

yea i plan on useing it for driftingas soon as my friend welded his is when he bacame so much better

ive heard of people saying that if the welds brake your screwed, that it will lock up and spin out

is that truecuzz i have to use this car for daily driving to

when you have it welded you permanently lock it, so your rear end will be more loose, especially in the rain. while that is good for drifting, it can be dangerous to yourself or others on the road. cars have differentials for a reason.

[martins_240sx]

seriously if breaks the welder needs to be fired. I really dont think it will brake if done correctly. now the have shafts on the other hand

[chalmer240sx]

have shafts?

[martins_240sx]

sorry i mean half shafts

[SullivanRacing06]

let me get this str8, you want to weld a diff i n your d/d 240? na bro, youll be better off going with a lsd or vlsd, unless drifting is that important to you

[Justin35ll]

How well does the vlsd preform? I'm assuming that is the one out of the j30 or whatever. I would get one, but I see them as just being stock off another car.

[martins_240sx]

I have a vlsd in my hatch and a welded in my coupe. the only time I can tell the difference is when i turn into parking spots or sharp slow turns. my vlsd is out of a j30 it locks everytime, got it for $40 bucks at the junkyard with only 4*,*** miles on it. it cost me about $40 bucks to weld my other one. I like both in their own distinct ways. I have to switch what car has what though, since my hatch is my"track" car.

[chalmer240sx]

yea i mainly drift but i also use it to get to work and school which only less than 1 mile away so its not much driving

more drifting than anything else its a stock s13 (ka24e) so it doesnt have a crap load of power so im not really worried about the drive train

ive just heard stories of people that said the welds brake and the car spun out

ive also heard if the welds brake it just goes back to open diff

is either of these true?

[adrianfromthecastle]

wait till it rains...

you'll hate having a welded diff, especially when trying to accelerate on the freeway.

[navysnail]

if the welds break, it will trash your diff. your talking about welding gears that are designed to turn smoothly.

about the car spinning, out, that is a definite possibility if your welds fail, as with any catostrophic falliure such as that your going to have a very rapid change in the handling dynamics of the car. if that were to happen on an interstate off ramp or anything...not good

[chalmer240sx]

thats what i heardbut i also heard that if the welds brake it will just go back to open diff

[long shot]

MY daily driver is welded n its been that way for about 2 months, i love it minus the pulling into parking spots (rough)

+1 for welded diff! i used to have mine welded when i first got the car and loved it! driftinr is sooooooo much more comfortable with it, although i cant compare to an lsd/vlsd since i never got mine installed. i welded mine myself and the welds broke and sent chunks through my cover resulting in a fluid loss, resulting in bearings overheating ,resulting in locking up the damn thing doing about 80! i didnt spin out just skidded to a stop. real fast! i got an open diff to put in since its my dd but plan on going back real soon. and about slow turns... yeah its true it sucks. my inner tire on turns hopped like a mofo,shaking the whole car.(stock suspension) i would highly recomend suspension at the same time or asap as the welded diff.(it will make your tires slide/squeel instead of hop.

NOTE: i do not recomend welded diffs to those that are not 100% comfortable in there car. NO NEWBS. it is truly dangerous, know your car inside and out before you go around welding your diff!!!

Cant be put any better

if this were to happen on a turn (when the most stress is on the diff) or in the rain, it could easily cause you to loose control and injure or kill yourself or someone else on the road. also note, it destroyed the differential, not caused it to become open.

thats all i have to say about this topic.

[martins_240sx]

If your wheel fell off in a turn( when most of the stress is on the wheel) or in the rain, it could easily cause you to loose control and injure or kill yourself or someone else on the road.

Not meant to mock you but to show that the outcomes can be similar with many areas of a vehical that we modify.

[SullivanRacing06]

it all comes down to what your wanting to do with the car, for a dd then mabey the welded diff mite be a little to much when tryin to drive slow in a parking lot or around a corner with a cop behind you, but if you dont mind then do it, i like the vlsd for a dd but allot of people switch that out to a kazz

[bikerskater]

lil late butt wanted to add my 2 cents but i have used vlsd for a lil and a 2way for a really long time and now a welded. Vlsd sucks only good for a lil bit with a low powered car and ok with a high powered car. 2way is pretty good but like i did i thought it was amazing but the clunk gets kinda annoying and scares alotta ppl especially when one a date but the thing that sucks most is you have to wait even thou its like .001 of a second you can still tell and sucks when it unlocks hardly happens but can still happen and the fact you have to rebuild them every 6months or so. welded though i have had for about a month and cant really say anything bad about it you just have to be cautious about it and always remember its there but same goes for a 2way. drifting with a welded is like sex thou compared to anything else and rain is pretty much the same i mean you feel kick some times but if you have a welded ii presume you drift and if its in your dd i know you street drift so you should know what to do. and as for dates go lol girls think its funny

[ambushdrift]

I ran a welded diff last year and its definitly the best bang for the buck.. Granted plan on replacing your subframe bushings and get used to a terrible turning radius under low speed. I have never had a clutch type lsd so I cannot compare there, but I have had vlsd's and they are unperdictable when drifting and I personally never liked them. Just make sure get someone to weld it properly!!

[OutToWinPAHC]

Have it welded and plated.

Like this Not this

You can see what plating is better, the welds have more contact all around.

[RustspecS13]

VLSD- blows. They can work "OK" for a little while but they have to slip first then the heat and fluid movement inside the actual diff starts to lock it. But it only provides limited locking power, and when they get really hot they stop working. Like on a low power car after autoxing or drifting, and then it unlocks on you when your going 3rd gear around a bank, thats really bad.

So VLSD is a temporary locking setup AKA horrible.

Welded- My friends run these and have no problems what so ever. Here in ohio theres alot of drift cars running around and I know most of them. Its probably 50/50 welded and clutch type in the cars, and theres no problem what so ever.

Ive personally driven my friends s13 in every weather possible with a welded diff and theres NO PROBLEM what so ever. If you have bald tires yea your going to have problems. But any car will. It requires only a minute amount of brain power to safely drive a welded diff car in the rain as long as you dont do retarded speeds around corners. WOW big shocker there. And as far as street tire wear, it depends on how you drive. One of my friends it was a problem, and my other friend didnt have a problem at all. It depends.

Summary- If some one competent welds your diff, then its durable, and they are completely predictable since they are 100% lock 100% of the time. The only comprimise is tire wear, and thats not even all too bad. Its a GREAT temporary setup if your saving for a 2 way.

2way/1.5way/clutch type- What I run and I LOVE IT. I daily my car and my diff has 25K miles on it or so and about 30 drift events and pratices and 5 autocrosses. Locks perfectly every time and I change the fluid every 5-7K miles. I should probably change it more often. Yea it clunks but thats the price you pay to not wear your street tires out, and still have perfect full lock when you need it. Who ever said you need to rebuild it every 6 months, ignore them they are doing alot of things wrong.

Summary clutch type is more expensive but durable, streetable and trackable all at the same time.

I personally drifted for two years semi-seriously (I was poor so i didnt get to drive in too many events) then I bought a 100mile old KAZZ 2 way and it rocks, and since then ive driven several welded diff cars on track and on the street, and one VLSD car on track and street. Dont waste your time on VLSD, and get a welded diff asap, and then save for a Clutch type. I really wasted 2 years worth of drifting with an open diff, and I wish I would have gotten a welded diff but people told me its dangerous and all that but its not at all.
