What are the advantages of the 2 way LSD over the 1.5 way? I'm hearing that the 2 way is the best for drifting but I don't really understand why. From what I've read, it seems the only difference between the two is that the 1.5 way doesn't activate as aggresively during deceleraton, therefore creating less understeer. They both activate during acceleration, so I'm unsure of why the 2 way is better, because I can't think of a situation where understeer could be a good thing.

And this may seem unrelated, but what sort of LSD do cars like Ferrari's and Lamborghini's have? I only ask because again, from what I've read, it seems that 2 way LSD's are too aggresive for street driving (in the general population's opinion, not drifters). So I was curious to know if there are any production cars out there that have factory 2 way LSD's. Thanks

 

You got it exactly right. 2 way locks during deceleration.

Did a quick google search, "ferrari differential", theres tons of into if you search.

Scroll down to "electornic differential"

 

I prefer a 1 or 1.5 way for road racing as it is a bit smoother, but for drifint, a 2 way is preferable. The 1.5 way does give some locking on decel, but not as aggressive as a 2 way

 

so the only advantage to having a 1 or 1.5 way is the ride is smoother? if you don't care about that then go for the 2 way. is that you guys are saying? also what about the J30?im thinking about getting one but im unsure how will that small change in gear ratio effect the performance?

 

Thanks for the responses everyone. I'm still unclear about something though. What is/are the advantage/s of the LSD locking in deceleration? It seems like it wouldn't have any positive benefit. Seems it would just induce hella understeer (and I can't imagine how that could be desired).

 

Anyone Know Where To Get a 95-96 J30 Diff. online? its suppose to bolt right in place of Stock S13 diff. keeping the S13 half Shafts. I think this will be the Best alternative as far as price and streetablity goes, while still being able to drift. And i looked all i can find is info about swaping into 240sx and websites that say they have it and then they just carry basic oem parts.

 

Be careful, iirc the ratio is different, but i could be wrong.

 

i think the ratio on the J30 is 3.916 Ratio and stock is like 4.083. I Don't know what difference it will make. but alot of people do that diff swap so i can't be that bad right?

 

what a s14 vlsd? 1or 1.5?

 

Do many people use 2 way LSD's on there daily drivers? Still trying to figure out if a 2 way will be a major nuisance. Will there be noticable wheel hop on the inside tire regardless of the angle of the corner? Meaning if I am going somewhat slow (say 25mph) and taking a 90 degree right hand turn (lets say I'm taking a free right at a stoplight), will I be able to feel noticable wheel hop on my right rear tire?

 

im still decieding weather or not to go with the J30 diff or spend 800 bucks on a kaaz. i don't want to spend that much money on one though.

 

**** i just say weld it, i dont think lsd's are reliable if you plan of drifting

 

Let one thing be clear: Please search. :]

As far as your situation goes, you should know that you're going to get what you pay for. If you're really hardcore into drifting, and you can sacrifice the comforts of daily driveability, then go with a 2-way. It's efficient and like everyone else has said, it locks on both accelleration and decelleration (so you will always have response when you either get on the gas or downshift).

Personally, I had a Kaaz 2-way differential, and I loved it. It worked amazing, and it was a lot easier to control when in drift; essentially it was more predictable. I've never used a 1.5 way, so I wouldn't know, but my 2-way did clunk like no other. I'd be at the mall sometimes, and you could just hear it clunk clunk clunking away. I didn't really care though; but that part's up to you.

Here are a few threads that I found when searching, they answer several of your questions:

Good luck with everything! :]

 

Okay I guess nobody is allowed to ask questions here at club240.com. Since you just get told to search this forum, or other forums or google to get anwsers right? Correct me if im wrong, isnt this what a forum is for, disscussing 240's and what we are trying to do to them. I'm sorry we don't all know everything about our 240's. Thats why we joined this forum in the first place, to learn something more. But i guess we will just stick to google and our "search button". Or the Mods my get us and ban us for asking questions when someone somewhere on the internet might have covered it before. And catching **** from other people that think they are mods in this GREAT AWESOME club240 forum.

 

i love my 1.5 way that everyone flamed me for saying came stock on my 240...still hunting the window sticker to prove it though, gf moved it so i may never see it again
