OBX LSD into wagon AWD tranny???

The AWD wagon transmission has the same FD (4.25) and gear ratios as the CRX/Civic Si L3 transmissions. But does anyone know if the differentials are interchangeable? Specifically, can I buy an OBX LSD for a CRX Si and put it in my wagon tranny?
Thanks.

    No.
    And I thought the RT4wd tranny had a 4.43 final drive
  • Super low 4.512
    1st gear 3.384
    2nd gear 1.950
    3rd gear 1.275
    4th gear 0.941
    5 speeds 0.783
    Retreat 3.000
    Reduction gear ratio Before 4.428 later 2.529

    This is why my wagon is at 4100 rpm in 5th at 80 even with big tires.


    Also found out as mentioned above the the diff is completely different. Apparently it uses two different FD gears:

  • How different is the EG ESi D16Z6 diff to the L3 one or the one in teh AWD tranny ?

    I might have a chance to get a OBX LSD for teh above fairly cheap and if there is a remote chance of it fitting...

    What's the beef? Is it just too physically big to do the job ??
  • Sucks to answer myself but:

    Search for "intermediate"

    Is he correct in saying that the end of the shafts which do into the box have a biggger diameter?

    Anyone know what size they are on the EK Civic's because apparently they did get an intermediate shaft.
  • OBX = small shaft, not going into 4WD setup.
  • Yeah, I resigned myself to that i nthe end.
    I'm not giving up tho. there must be a combination which will work without having to go for unequal lengths and without having to buy a Quafie for the L3 box :lol:

    :? but you don't have a L3 :?: you've got a 4WD.

    The RT4WD boxes are still L3's.
  • SiWagonSiWagon Council Member
    :cry: They make a aftmrkt LSD for only certain 2WD L3's NONE for the 4WD.One option is a JDM Honda LSD.Better bet is adapt 1 from a NISMO 240Z to maybe a 280Z.Miata diff might work,BUTwon't handle hi horse power.
  • I'm going to get a L3 ZC Diff and physically compare it against the diff from the 4WD box.
    Even over here where we get the ZC L3 stock, LSD's are uber rare.

    You don't need to pay JDM or Quafie prices .Read my LSD recommendation:

    No, just NZ prices to get one shipped over here :)
    Pacifer, I'm all yours :lol:

    TBH, I'd rather thave a front one than a rear one.
    If it's gonna fit then a quafie is totally awesome. I've driven them in a B16 CRX cable tranny, compared to the OEM JDM Y1 LSD and aftermarket clutch types.
    The corner grip experience is out of this world. It's just un-natural as to what it can do.
  • Got pics of a 4WD stock diff?

    How about a digital caliper?

    Some day when I get time (RIGHT!) I'll did thru the American Honda Parts database to see what I find.......

  • Gearbox is still in the car. :?

    When through the UK parts database and found the code for the diff in the D16A9's box is a different part number.
    Now that's not the be all and end all, but other Hondas like the ITR and the MB6 share the same diff and have the same part number :roll:

    no, I'm not giving out the ID/password, but they are the same.

    google FTW :lol:
  • did you download the CD/ISO?

    I just access the database at the Troy Warehouse.
  • There is a good one here:

    But you must think in Russian :wink:

    Looked at converting the ISO like the Dutch guy had done a while back before Honda sent him a cease and decist letter or something. Funnily, he wasn't up for talking about it :lol:

    What's Troy Warehouse ? Some outlet in the US I guess :?

    Honda's Parts facility in Troy, Ohio. I used to make daily runs there for a local dealership, used their TOYOTA pickup.
