New OBX Helical/Torsen LSD for the 240sx on ebay. Opinions?

[95lstegman]

if you did that, would the wheel with the too short output shaft ever get power? it sounds to me like the teeth would never engage in the differential, and therefore no power would ever get to that wheel. heck, might be an advantage on a circle track, except that on circle/oval tracks you turn left, and i think the right wheel is the one in question, so it would still be your inside wheel. oh well. guess just going in circles blows for yet another reason.

From what I have heard, and am pretty sure is true from looking at the internals, a vlsd will function EXACTLY like an open diff if the open diff outputs are used. Here is a picture of the shafts of one for you to take a look at.



^off of an ebay auction up currently.

Ok, now I am totally confused. I'm far from needing a dif yet(car is getting restored and a multitude of other upgrades before I consider this) but I have a HICAS model, so I already have a VLSD. Unfortunately my car had over 180k on it and by the time I get everything else done, the diff will probably need changed. Now would I be able to use the OBX one if it is designed for the open diff models? Also is there any way to "restore" the stock VLSD? I didn't think there was but I just want to check.

if its for an open diff you would need open diff shafts.. BUT unfortunately I believe the s13's with vlsd had the 5 bolt output shafts. If this is the case you will need to find some 5 bolt shafts off another open diff car (did these even exist?) OR easier swap the axles AND open diff output shafts off a non vlsd s13 onto yours. You can't restore a viscous, the viscous goo is sealed inside, even if you drain all the gear oil out the viscous is still sealed inside the actual viscous unit. Once it goes, its gone...

typo, I said I thought the open diff cars had 5 bolt when I think the vlsd ones did.

No, s13s with open diffs have the 3x2 shafts (6 bolt ones). the 5-bolt diffs were found on some infinitys, and the r32 skyline(I have a diff from one of these, swapped the axles and diff into my car)

"but s14 SE's did have the viscous"

Nope, good call, but the the only SE S14 that came with them also had abs as well, i do belive together in some sports package. I'm sure there are SE S14's with abs and no lsd, but the majority of the S14's with ABS do in fact have the vlsd.....its a shame my SE S14 has niether

My last car was a 1996 240SX SE it had the VLSD, no moon roof and no ABS. Those were the pluses. The minus was it was an automatic and I was planning a transmission swap when I totalled it...

[top_secret]

like I said, supposedly it was an option for any car. And of course all of these people who "find" a used car... you have to remember that it might have had a vlsd in there and someone grendaded the rear end so the dealer put in an open diff, or vice versa, before you got it.

but anyway, this is all a moot point until we find out for sure which output shafts the diff will work with. It can only work with the vlsd ones OR the open ones, NOT BOTH.I'm not sure the seller of the OBX crap is knowledgeable enough to know the difference, if he is, he hasn't revealed it yet.

[k6kicker]

if it works for the open dif's out shafts then they have a gold mine ready to tap

Well I'm already frustrated with OBX. It seems like I only get one reply to an email per person and I've used mine up. When I sent the second email to try and clarify what Dave had written, I got nothing back. So I wrote Dave again and then wrote to Info again. Maybe they are all on vacation. Maybe my wording wasn't eloquent enough for them. Here's what I wrote the second and third times:

Dave, As I was re-reading your email to me I realized it's still not all that clear to me that your LSD will fit in my car. I'm really hoping you could clarify things for me before I make a purchase. So I'm clarifying my question for you a little better. Like I wrote before, I have a 1997 240sx se, 5-speed, with an open differential. Meaning I do not have a limited slip differential in my car. With Nissan 240sx cars there were both open differentials and limited slip differentials (viscous type) depending on which model you purchased. The open differentials and limited slip differentials had different output shafts of different lengths. Some output shafts even had different bolt patterns. For example, when I look for a NISMO LSD for my car, I find two different models. One model fits a 240sx if it has a stock open differential and a different model fits a 240sx if it had a stock limited slip differential. So, will your helical LSD fit in my car, which has a stock open differential and obviously matching stock output shafts? I really hope so.

Sincerely,

I wanted to call but there is no phone number listed, just a fax number. So, If anyone else wants to write them, or everybody wants to write them I think it would be cool. They can be contacted at [email protected] and [email protected]

[top_secret]

typical ebay bull****, no phone number, crappy reply time, etc...

thats pretty much run of the mill ****, stone mountain racing, obx, ss autochrome, etc...

[ShadowKnight006]

O i looked all over their website and didn't even see this thing. Anyone care to point it out on the website?

[D-UNIT]

*edit: Also, don't expect it to work if you make huge power. In a 240sx anyone making much more than 300whp probably will break an obx. If your running a stock turbo SR, CA or RB you'll probably be just fine, even for a long time.

Please add to my information and correct me where i'm wrong.

It's funny how you mentioned all the options except shall I dare say low boost KA-t. Also no one has actually broken one at all, only axles.

[sssrdub]

I went ahead and ordered the OBX helical today. Now, I'm curious if I need the vlsd output shafts or not. Anyone got a spare set to sell? I was hoping to recieve it by the end of next week and install on the weekend, but I can't if I don't know which shafts I need. Mine is an S14 with open diff.

Auction listing is very unclear. Says 89 -94 240sx. Then it says ALL S13 s14. Then again it says: Fits ALL 1989 to 1994 Nissan 240SX 2.4L models including: Base, SE and LE. But don't the SE's have viscous? That would be impossible to fit both Base and SE, no?? Confused. Should I buy the shafts too?

Hopefully, someone can update with clearer answers.

Hell yeah.....Keep this thread updated with the install...

[Badfish]

Somebody with an s14 over at zilvia installed one recently.

Why go to Zilvia when you can just read and respond to the one he posted on NICO yesterday?

zerothread?id=157910

[Ajax]

He's also got a thread here.zerothread?id=157910

[VR6erator]

[wannawangan]

Any update to this?

[progman]

Anyone ever install one of these?

[StricNyne]

So basicly nobody has any real experience with the OBX LSD in a RWD car. And all of you are just pulling out anecdotal evidence from completely different setups. So what if an OBX muffler got welder wrong, $425 differential internals would have to be somewhat well made or severely marked up. R200 diff is pretty solid, and a well made copy could work. But nobody has actually tried one yet. I dont care if it broke in an Integra.

BOOYAH!!!!! seriously i dont own it, but you guys are comparing a totally diferant platform...

[turbo2nr]

form what i hear on zilvia, some guy is doing a ongoing review on the obx lsd, installed in his 95 s14, so far it holding up well, no complaints, he drifts the car. its been almost a year since its been installed and it works well for him no complaints. ill try to look up the thread when i get home but i think zilvia requires you to be a member to view posts..

[S13_Struck]

im glad this post exists, i will now be purchasing one of these for mine because it was a welded diff now and i wanna get away from that.

[StricNyne]

i am going to buy this on my rb powered S14 i thought about it and decided i dont wanna spend 1k on the tomei anymore

[maryjane]

wouldnt trust any of their products

[StricNyne]

i felt that way, but with people using these for around 2 years and their diff hasnt locked up and caused their car to flip into a rivine i think its about time i bought mine

[D-UNIT]

seriously thou 27xx posts and still no LSD installed.... Shameful

[StricNyne]

i did have a diff on my s13 i had a r33 one i got when i got my half clip, i got a s14 now and i just got it running like week ago lol

[sean@z1]

sorry for the thred jack carlos yo send me a pic of i want tosee how it is looking so far
