Wouldn't an S13 have a shortnose R200?

Thanks for the idea. It seems to be a 37/9 =4.111 R180. Or at least in the USA. http://www.nissanpartszone.com/Page_Product/PartDetail.aspx?ModelName=720%20Pickup&ModelYear=1984&ModelSeries=720&FileType=236&SelectConditions=(1%3dK%2fCAB%3b4%3dF5%3b5%3dLONG%3b6%3d4WD%3b)&ShowConditions=(1%3dK%2fCAB%3b4%3dF5%3b6%3d4WD%3b)&seeDesc=False&goBack=True&SectionNo=F&ComponentsNo=381

I am compiling a list of Nissan part numbers for R200 longnose ring & pinion sets. The photobucket image below is what I have accumulated so far. If you would be so kind as to add to the list, it would be most appreciated. I will update it as new info becomes available. The ratios are only guesses as to what might be available (see the link at the end for all possibilities). If you also know the ring gear bolt size [Type 1 (10mm) or Type 2 (12mm)] that would be helpful. Thanks in advance for your time and trouble.

Thanks for the replies. The HR31 info is a good double check, as the r/p part number should be the same for the 4.375 amongst all models. The Z31 parts mocrofiche has been put on-line: http://www.az-zbum.com/z31.fiche.shtml. Anything like that available for the HR31?

Thanks very much for all the feedback and info. I apparently put NISMO USA on the wrong track and the part number they came up with was indeed for a short nose. So after a whole bunch of searching I believe (one of) the right ones is: Nissan Silvia BS12 86-88.3 CA18DET, 4.375 with 12mm ring gear bolts (aka in the US as 200 SX). Would you guys agree?

I forgot to mention that I have always had this option for higher numerical ratios, but I was looking for something a bit less dear – preferably used. http://kameariusa.com/L6_r200.php Thanks for everything.

Thanks for the model info and the leads. Unfortunately nothing higher than 4.3x was imported into the North American market, and even 4.3x's are so rare as to be nonexistent. Some other Z sites that I use for info and parts leads: http://www.z31performance.com http://www.zcar.com http://forums.240sxone.com http://forums.nicoclub.com And a general info site: http://www.carfolio.com/specifications/models/?man=4444

Thanks for your input. After some pushing NISMO USA is now able to order the 48:11 - 4.363:1 from Japan. The closest think I have been able to find for available ratios across all models is the following info on LSD’s: http://www.nismo.co.jp/en/products/competition/lsd/pdf/lsd_price.pdf But it still doesn't cover the higher numerical ratios. For future planning do you know any source for R200 long nose r/p’s in the lower part of the 5.xx:1 range? Info like that is impossible to get in the USA. And Nissan Australia has never returned any of my email inquiries. If you have a link to a list like the above on the available ratios I would be very grateful.

If you have a link to a list like the above on the available ratios I would be forever grateful.

I would like to buy a good used ring & pinion gear set for a longnose R200 differential in either of the following ratios: 48:11 = 4.363, or 35:8 = 4.375. I believe they were available in the S13 Silvia in your neck of the woods. For shipment to Las Vegas NV. Glad to pay via PayPal or other reliable means, or trade parts. I have a bunch of Z31 spare parts I am and will be selling on eBay in the USA.

I would offer to buy your R200 longnose 4.3 but it would cost almost as much to ship it to Las Vegas. Any chance you would sell just the longnose 4.3 ring & pinion? I have a bunch of Z31 differentials and engine parts if you would prefer a trade. Barring that, if it isn't asking too much, what is the best used parts web site in Australia for Nissan parts like that?
