So i keep getting mixed answers from ppl about weldeds in 350z's etc.. I come from the schassis where welded is everything etc. I know a welder who has done my diffs+everyone else in the area forever never breaking any. How bad would a 4.083 combo plus welded be on the diff. is that just asking to break it. This would be for daily plus occasional drift event every few months. I am used to diff chatter etc i dont care about how it drives i just dont wanna have to replace diffs every event thats expensive and stupid. I would like to have some imput from welded guys in this thread. thanks.

 

i hear alot of people saying they always break if welded (in a 350z)
i personally think it is the welding quality.

 

dont know anything about welded diff on the Z

but a friend of mine has a welded diff on his 240sx and its great for drifting

 

I agree with AngelsVQ that it depends on the quality of weld but I never heard of a lasting successful weld story.

Before I bought my LSD, I was checking the market place. You might get away with buying a whole pumpkin at a good price. If not then I recommend the Nismo2-way. You're fine with your choice of 4.083 FD

 

I've got two open diff carriers laying around that I could weld up.

I've got a Miller Syncrowave 250DX (300 amp) TIG so penetration of the welds wouln't be problem.

 

+1 on checking marketplace and eBay etc. I got my carbonetics 2 way LSD with 1 k miles for 300$

 

yea, i mean for 240's its always a no brainer 100 bucks vs 1k and it does the same and will never break ever.. but i really dont wanna have a diff break on me if im NA thats crazy talk. I see 350's snapping diffs and axles when turbo and drifting but not w/ under 300.. I trust my welder so .. maybe its worth the try and if it fails its not a huge loss of money then go the lsd route if i can find a deal like ur talking about.. under 500 or so.

 

Dude, if you weld it correctly, it wont break, i know a few peeps with a welded diff in their 350. And they go hard.

 

Ok, im starting to lean towards this, it sounds like noobs are taking it to the local exhaust shop cuz they hear its cheap and cool and then they break it easy.. im gonna get a spare in case and give it a shot.. Thanks.

 

I welded mine and ran it for 8-9 months with no problems at all. I put a VLSD in after that because the welded diff ate my BRAND NEW tires bald in 8 months. Now if you don't mind replacing tires and the chatter noise than it's safe.

Oh, and you won't need the 4.08 gears after you weld the diff.

There was one thing I did notice though. When parking in tight spots the inside axle would pre-load a lot. (probably normal with the welded).

 

^ dude even with my 2way that damn thing does the same ****... Its so noisy at low speed, but locks up so nice at speed.

 

I wont need the 4.083 but if im going in there is it worth it or a waste of time for drifting.. any experience with it.

 

If you're a good driver it's a waste of time/money. People do amazing drifts in a stock Z just fine.

Welds only break when done improperly. I've had welded diffs in various rockcrawlers, never broken any spider gears.

 

Waste of time. Your stock FD is fine for drifting.

 

+1 on the newb theory lol.

 

You wanna sell one of the open diffs.
