Hi all.
Can you help me with one tranny problem?
I have Y21 gearbox it is the same with S4C gearbox (s4c is mounted on civic 99-00si). I want to get LSD because my geartbox do not have. I find LSD for 94-01 Acura Integra GSR GS-R Type-R. Can i use it in my y21 gearbox without problems?
Thank you!
P.S. i will get OBX LSD.

 

obx lsd?id consider something else that is a little better quality. if you do get it check all the parts for tightness, i forgot what all was said to check there was a write up on it. search if you do decide to purchase it.

 

i have read many good things about the OBX LSD.

 

Quaife LSD.

just a few and i found out that the review got deleted for some reason.

if it breaks then you risk breaking other parts, and its lifetime warranty only covers manufactures defects.

 

I do not have enough money for Quaife.
Can i use LSD from 94-01 Acura Integra GSR GS-R Type-R to civic 99-00si gearbox (S4C) or not?
Where i can find OBX LSD? In ebay do not have.

 

i would just cross reference part numbers on quifes website. then if there the same then you can use the lsd you want.

 

only problem i hear about OBX is that your axles will be in there tight, as in weld tight that if you want to remove it? good luck I guess. hehehe obx.
you might wanna search there are horror stories about this. what if your half shaft fails? risk of breaking the tranny with it?

 

I get OBX and will see how good or how bad is it.

 

I get it and open it.
IT IS THE SAME AS QUAFIE!!! NO DIFFERENCE!!!
OBX is Quafie for 375$
When i mount it in gearbox will say which LSD is better. Stock LSD or OBX LSD.

Of course they LOOK the same OBX copied the quafie on the design the difference is in the quality of the materials and in the quality of the product. Like someone else said make sure everything it tight and installed correctly. Just becuase they look the same does not mean they are.

 

Shake your OBX, they have been sending LSD's out with some loose internals. You should have someone tear apart your OBX before installing it. OBX has no quality control during the assembly of their LSD's the consumer has to go through the LSD and be the Quality Control.

If everything checks out there should be no problem.

Right. Good luck with that.

I have both, and there is a huge difference.

My post from another thread:

I feel the need to post this in every thread that deals with OBX LSDs. My experience is with the D-Series model only.
Here is my review of the OBX LSD:

It was .033" wider than the stock unit. The stock shim in the tranny was .057". Fine. So I need a .024" shim. I go to Honda, and what do I find? Their thinnest shim is 1mm, or .03937". ****. Ok, custom machined shim time.

Now I have a .024" shim. Cool. Time to press on the bearings. ****!!!! The god damn diff bolts stick up so far that I can't press the bearing all of the way down on the ring gear side. I had to pull off the brand new carrier bearing, and remove all of the bolts that hold the diff together. I find that one of the counterbores for the bolts was not finish machined. Time to grind all of the bolt heads thinner for clearance.

Now the bearings are on, and It's time for the ring gear. You must be kidding. The OBX diff body is so much larger than the stock diff, that all of the ring gear bolts bind when they are tightened. Time to grind .020" off of the washer head of the ring gear bolts. Now with the thinnest wall Snap-On socket I could find, I was able to assemble the ring gear to the diff.

It's now in the tranny, and time to insert the axles. No problems.

First drive, what the hell? I just installed remanufactured axles, and it shudders badly under load. Ok, I've gotten bad axles before, so back to the parts store.

Came back with brand new axles. Normal installation, no problems.

Out on the road again, same shudder. I pull it into the driveway and jack it up. I can seriously move the axle cup within the diff .110", as measured with a dial indicator.

Basically the axle bores are tapered, or way out of tolerance. My OBX LSD is a piece of ****. Many people have great success with the B-Series unit, but the D-Series models are really fucked.

I thought I could save $400 by going OBX, but now I have spent over $600 more considering I ended up purchasing two new sets of 80mm carrier bearings.

 

Material is the same because they are manifactured in the same chinese factory. One consignment is stamepd with quaife, other with OBX. This is the difference.

Jim Truett your shim problems are absolutely normal!!! I think that may be your LSD is not for D series...

 

i would get atleast OEM TYPE R LSD, or Qulife. there the best

That whole statement tells me you don't have a clue.

Quaife is a U.K. based company, and their manufacturing facility is there as well. You have obviously never seen, let alone purchased a Quaife.

I understand that it is usually necessary to shim a new differential. My Quaife needed a .005" thinner shim, and it was easily purchased from my local Honda dealer. The copied OBX is so far out of tolerance that it is obvious the hack of an engineer that reverse-engineered the Quaife was not concerned about fitment. They obviously have not even tried to install one of their units.

You need to deal with the reality that you might have just wasted $400. Good luck.

Materials are not the same as Jim has stated they are not manufactured by the same company. In at least one of the better overview threads they found that even the bolts and harware that hold the OBX LSD together are inferior to those used to assymble the Quaife, meaning the bolts and such on the OBX are not as hard as the ones used on the Quaife.

PARADOX I think you need to do a little more research into the product you just bought or else read credible info becuase if you did research it you were misinformed about the OBX.
