welded diff

[Odysseus]

Is that plated welded diff from an S13?

Yea the ring gear is off in the pic so the opening looks larger. I have blown a Cusco clutch type so I will be having my old open end welded with a plate. Its not a daily car at all so why not. They seem to handle power and torque when properly welded. The trick is to clean the well out of it and wire brush the crap out of it so the welds are really strong. If your not welding it I suggest you still do this. You never know how well the welder will do.

Cheap bastards...

Kidding. The plate thing is actually almost as strong as a spool. VLSD isn't made for high power applications, true, but lets think of the car most of you are driving. You're rocking, what, 300hp on average? Well, just considering the modified folks, anyway. Your main advantage, what makes the cars fast, would be weight, not power. Getting a VLSD to handle 300hp isn't hard, and the driveability savings are great.

Rain isn't actually a problem for a spool. Your problem will be ice, slush, and mud/sand. If you live somewhere it never snows, or freezes, and people clean the roads weekly (where is that? heh), then you'd be ok. The problem is, nice day, looking around a corner thru the passenger side window, and you hit a patch of oil, sand, slush, mud, whatever, and suddenly you're facing the wrong way, into a guardrail, wall, or sliding down a cliff. And it's not a "good driver, bad driver" thing. Nobody has road radar. Be on the safe side, and take care of your ride. If all it does is drift on tracks, then a spool is great, makes your life easy. If you're on the streets, as I suspect a lot of you are, it makes your life difficult, and there's no sense in it.

EDIT: Oh, by the by, you folks that are putting 500 to the wheels and turning tires into a strange smell in the air, try not to get offended. You're not actually the "average" part of the average

My friend had a welded diff and it was terrible....

Could hear him coming as soon as he turned, wheel hopping and all.

Then his rear end blew up and he went to an open, much better.

Buy a clutch type or even a helical. My OBX Helical has held up great, granted I just DD it spiritedly. But it does see its abuse and sliding often.

[OutToWinPAHC]

Everything has an application. My HP/torque curve is much different then a 500HP SR/RB/. 462 ft lbs of NA torque on demand was too much for the 1.5 way clutch type. Its much more on the low end when you don't have to spool up.

Hopefully the welded diff will work out in my application, if not I may try carbonetics. My car is not a slider, its made to be fun and make good track passes.

I am surprised noone make an aftermarket full spool.

hahahaha some of you guys might not understand this.

to the few people that have been saying wait till it rains are champs.

hahahahahahah do not weld your diff if you get a lot of rain or snow. you will more than most likely die.

just drive down the road at about 50 maybe 60 let off the gas and watch your car go down the tubes.

imo spend the money do it right.

just drive down the road at about 50 maybe 60 let off the gas and watch your car go down the tubes.

Your drivetrain is not going to go into compression lock from letting of the gas alone. Maybe if you throw some weight transfer in there too you may spin wildly out of control. Granted I do have to heel-toe under breaking downshifts in corners.

I ran a welded daily last year putting down around 300ft/lbs to the wheels and Im from upstate NY (aka it rains like 9 out of 10 days) and im fine with it. Actually its wicked fun and easier on rubber in the rain.

All I have to say is if its your first FR car and you havent gotten a feel for the car and how it reacts under weight transfer and loss of grip then your F'ed in the rain reguardless if its a vlsd or clutchtype and welded. Get familiar with open, then go from there! good luck

If you don't have money and hate one tire burnouts - weld it. You'll get used too it.If you do have money buy a real LSD ( your choice 1.5w autox , 2way drifting etc.Don't even waste time on a Vlsd like I did. Once it wears out - open diff!!! or worst yet it can unlock mid corner or mid drift and U will be investing in a new front end and lower control arms and ur back to - square one.

[D-UNIT]

honestly thou with a welded diff you could probably do this very easily.

With Skillz Of Course!!!

[helluvasinger]

Does anyone know of someone that does welded and PLATED diffs?? Maybe even a price??

The only way I'd feel comfortable with a welded diff is if was also plated.. just more secure to me..

[OutToWinPAHC]

Yeah down in Philly JDM Will does them at Northern Liberty Auto, and so does Nick at Elite JDM.

Nick is doing mine right now. I pick it up tomorrow, I'll take pics.

[helluvasinger]

Nice... and it's even close to home..

I'd like to see them pics!!

[3CL1P5]

here you go...this is a picture of my diff right after Powered By Max welded my open diff. Martin is an amazing welder.

this is the one off the site

and this one the one that is in my car currently.

I've only driven it once so far but its very interesting to say the least...although i have 100% confidence in Martin's welds.

Welding a rear is cheaper and easier than finding a 2way LSD or a full spool rear locker

[Yasko]

Don't mean to thread jack but, if you weld your open differential then realize you don't like it. Can you then take out the welded and buy a 2way and drop it in? or is it once it's welded it's welded?
