Nissan rear dif. gear ratios

[Sleeper s13]

I was wondering what different gear ratios in limited slip differentials nissan has employed in their sports cars like the skyline,Z car, and the 240sx/silvia (past thru present)? and if anyone knows, also the possible hp tolerances of each. a legitimate tech web page would be great.

Infiniti:

Q45 : 4.09 R230 LSD - this diff can take ~475rwhp
J30 : R200V


Nissan:

Skyline : R200 4.3
280ZX : R200 with 3.54 3.90 4.11
300ZX : R200V
240SX : R200 or R200V

To elaborate:

Q45 does have R230, but I believe it's the 3.69 ratio, same as the Z32 TT (they share rear diff, subframe, etc...and it DOES NOT bolt into the S-chassis)

J30 comes with 3.916 ratio, R200V

300ZX: N/A = R200V, 4.083 ratio, same as S13/14...
Z32 TT = 3.69 - see above

240SX comes with 4.083, either VLSD or open

180SX from Japan came with 4.083 and 4.36, both in an R200V case

Nissan Motorsports offers a 3.7, 4.36 upgrade and a 4.64 upgrade for the R200(V)...

Q45 well the ones i've used at least are R230 LSD with 4.09 rear gear. not 3.69

Not trying to be argumentative, but to clarify this point:

- - 1997 Q45 specs - - (http://tuneman1.tripod.com/infiniti-q45-98.txt)

- - 2001 Q45 specs - - (http://www.infinitihelp.com/Infiniti/Models/2001%20Q45/Q45spects.htm)

Maybe they were different in years before 1997...Infiniti did do a lot of redesign then.

And it seems maybe those were Touring models - I could see how the regular Q45 would have a numerically higher ratio.
