R200 Diffs

[Fitzpatrick Speed Works]

Hey all, i was just wondering does anyone know the specific diff ratio's that various r200 diffs come in. I know the most common is 4.11, i know about 4.3 and also 3.9's but what im interested in is there anything substantially lower(or higher hahaha) available to fit my skyline r200. I was after perhaps a 2.7 or something of that discription!!! Thanks for your help in advance!!

The S14 manuals came with 3.73. I don't know of anything lower than that out of the factory. If you go see a diff shop they can usually find out what is available pretty easily.

the lowest i have seen/known about is 3.5. I dont know about something as low as 2.7

Are we talking long or short nose R200 ?? Long nose was fitted to most 6-cyl Nissans (and some 4's) up until about end of 1989 (end of R31 series), while short nose is basically 1990 on (r32, etc). CWP sets are not interchangeable between the 2 types.

Anyway for the long nose R200, tallest ratio diff made is 3.3 but is very rare as it was only fitted to about the first 6 months of production RHD auto 260Z's.
