    Hi Guys, a quick update to this thread.....

    This morning I purchased a R200 differential from a local JDM source for $400 Canadian. It came out of manual 2003-2008 Nissan 350Z and has a 3.538:1 Ratio. I will have to do the machining modifications to it as outlined on the Goodparts website. I’ve ordered the mounting kit as well so that should arrive in the next couple of weeks.

    I decided to pick up the Diff locally after doing some math....

    From Richard the Diff would have been $600 US plus $100 shipping to my mailbox in Niagara Falls, New York. After that, I’d need to get it across the border...I expect that will cost me an additional $50 Canadian Shipping and $80 in Canadian Taxes.

    So, in Total, with taking the currency conversion into account it works out to the following....$890 ( diff and shipping) + 80 + 50 = $1020 Canadian

    I will update this thread with the actual machining costs incurred on my $400 Diff and see how the numbers work out in the end.

    Cheers,
    Tush

      Hey Tush:
      Following my last comment, I recommend that you determine the condition of the R200 clutch pack (the LSD friction discs) before you install that pumpkin. Take it to a shop that refurbishes diff's and ask for an evaluation. The shop should have the spec's for the diff. Guard against the shop making work for itself. They maybe able to test it without opening it but if they open it, have them let you inspect it disassembled or show you pictures of the discs. I wish I had done this, instead of just popping the pumpkin in. As I stated earlier, I am having my spare refurbished this spring and installing it and then refurbishing the one presently in, mitigating down time.

        Hi Al, good idea. The rear cover was off the Diff already as I wanted to inspect the internals for condition before laying out the cash for it. I can have my driveline guy take a look at it when I bring my driveshaft in to be shortened/balanced.

        Cheers,

          Oh, another question for you R200 guys comes to mind. I’m assuming that the two sensors on the rear of the differential are wheel speed sensors? ( based on the machining of the Diff flanges for optics). What do I do with the connectors? Leave the sensors in place and just cut the cables close to where they enter the sensor? Or, is there something else that’s recommended?

          Cheers,

            In my case I just cut the cables on the sensors. I also seem to recall that there was a vent line that needed some attention but I can't recall what I had to do.

              Thanks Phil. There is a vent line on top...I think I’ll just add a length of tubing and extend it downwards a little bit.

                Yes! Now that you mention it that's exactly what I did. A bit of tubing angled towards the ground so water doesn't get in.

                  I removed the speed sensors completely. My vent was damaged so I replaced it with a 1/2 inch copper tube cap. See pictures. Oh yeah, a new pinion seal might be a good idea also. I did not do any of this and have had no problems with the present diff but the rebuilt one will have all this done.

                    I do like the fact that there is no oil drips.

                    Also had to change the routing of the exhaust pipe, but this is a one-time thing.

                    A couple of years ago I picked up a vibration when decelerating that drove me up the wall. I actually had to original diff ready to reinstall when I found, after completely removing the LSD, and saw the two countersink screws had come loose from the bracket. (Shown in photo #3 near the orange lube sticker) I retightened using blue thread locker, which I should've done when first installing! I mentioned this to Richard Good, as a FYI.

                    I'm sure this addition helps the E.T. when auto crossing, if I ever learn how!

                    Hey Dick what screws are you referring to? You reference photo 3. Where is that?

                    local guy has been fighting a vibration but unsure if it’s on deceleration?

                      I believe he's referring to the two countersunk screws that hold the black mounting plate to the diff (as shown in Al's pic #3)

                          Yep. That's the two screws that came loose on me. Vibration was any time when not accelerating. Worse on deceleration at road speeds. Use Loctite here.

                          Since it's a chore to get to these two screws, as in removal of the diff, you'll want to check other things first, such as all of the U-joints, exhaust system, etc.
