Are their any ring & pinion gear sets available in a 5.13:1 or higher ratio available for the R200 longnose differential? Perhaps out of a truck, bus, etc?

Not available from a production car

4.6 is available but im not sure what car i comes out of. SW motorsport has the CW and pinion for sale

any higher ratio is only available aftermarket from

Very expensive though. Doubt if you will ever break one

Only available as new item, and will be expensive, like most good things are.
I bought four new CW&p's in 4.6 and 5.1 some time back, at over $1200 each for H190
I can get the R200 ones, but no second hand on that ratio, it is very much a small manufacture run, hence the high price.
How serious do you want?

Thanks for the feedback. I knew about the Kameari's but set it aside as a bit too dear.
None of the Nissan trucks, small buses, or SUV's in the USA have the high ratio longnose r/p gears I am looking for.
I was hopeful that you had other models available.
Or, that you might know what Marks other than Subaru use the Hitachi R200 longnose.
I am currently running 275/35-15 Hoosier A6's with a 4.11:1 CLSD on my Z31 and want to go to 335/35-17's for the rears. Hense the desire for a higher ratio to compensate for the taller tires.
I also sent emails to http://www.nissanparts.com.au/ and http://www.nissan-parts.com.au, but no answer from either.
Would somebody be so kind as to provide the website or email of the largest used parts organization in your area? The absolute best one in the USA is http://www.car-parts.com; almost all of the recyclers nationwide put their inventory on it.

Thanks for the info.
For the short term I am going to try a higher numerical ratio with my current 275/35-15's.
Could anyone verify that a Nissan Silvia, BS12, 86-88.3, CA18DET, could have a R200 long nose 4.375 r/p, with 12mm ring gear bolts?
And or for a Nissan Skyline, HR31, 4.375 Ratio, with 12mm ring gear bolts?
Hard to tell what's what for all the different Nissan models.
This was about the only thing that came close: http://www.nismo.co.jp/en/products/comp ... _price.pdf
Thanks in advance for your time and trouble.

I have an older Nismo lsd parts chart from 2005 which says that they do aswell.

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.
