Hi has any one any info on a R200 with 4.44:1
I am currently running a 4.363:1 but after new cams and head work require a different diff ratio
a 4.52:1 would be even better.
the car is a Clubman with a CA18DE on LPG

u want to go a shorter ratio again??
wow.. ive got a 1600 with s14 sr20.. GT2540 (440hp) tomei 264's.. 850cc inj. on 18psi making 241kwatw runnihng 4.4:1 R200.. and its gonna have very short gears and no top speed watsoeva.. im looking for a 3.9 or something for the future..

just a comparison 4 u.. i doubt that that minute change in ratio would even b noticable

have fun!!!

Depends on what motor you have to why you want that a low ratio. I have an l20 with a 3.9 diff but its way to high i need either a 4.4 or 4.6 so that it stays in the rev range and so i can use the revs the engine needs to make good power. I guess with your turbo motor it would rev to 6500 around there at max where as i run to 8 to 8500 to make full use of the power i have.

Ian,

I don't know of any car that comes with an R200 above the HR31 ratio (~4.375).

If the CA18DE box doesn't have an 0.864 5th you might want to look at swapping in an early 240Z gearset. Will give you 3% more torque in 5th as opposed to just over 1% with the diff change.
