Diff Ratios - R32

[VLRB20DET]

I have put a RB20DET in my VL calais, is it worth me swapping ratios form 3:45stock to a R32 4:36? Im going to do a bit of drag racing whats the best to use???

[Clint32]

Higher would be better for both the drags and street, reduces top speed but will give better acceleration.

The import R31's (with the early style R200 diffs), used 4.3:1 in the autos and 4.11:1 in the manuals(when they were fitted with the RB20DET). The original diff ratio should be on the build plate, RC43 for 4.3:1 and RC41 for 4.1:1 etc.

Are Nissan diffs "interchangeable" with each other? ie r33, r32, s14, s13 ?

[VLRB20DET]

hey Clint32 did you notice much difference goin from 4:3:1 to 4:1:1?, I read on www.calaisturbo.com that its's worth dropping in 4:3:1 that the r32 gts-t has combined with the engine/gearbox conversion to get the most out of the conversion, my only problem with the conversion is that the speedo is about 20km/h out!

My car already had a 4.36 diff in it which is now for sale. If your worried about the speedo go grab a electronic bike speedo and mount it in the front wheel, very easy, cheap and accurate.

VL dude, how are you going to get a 4.36 diff ratio for your borg warner diff? best thing to do is grab a pintara diff which is 4:11 and change the pinion and crown gear with your vl one. Thats about the best that your gonna get.

4.3 = 3700-3800 in 5th at 110km or around 3500 at 100km/h in 5th. mite sound like a bit. put your foot down and your on boost in around.0000000003 seconds lol.. so its alright for taking over slower moving cars.. or when you want to race your mate in 5th gear.. lol. but yea.. your looking at higher revs for any given speed in any given gear.. remember that. but i like my 4.3's

All 2wd R32GTs-t's have a 4.363 rear diff.

GTS-4's are 4.375

I just had my diff pulled down and it had 4.11 ratio from what I was told.(92 R32 GTS-T)

While I'm at it does anyone know where I can get a new crown wheel and pinion gear set (4.11) for an R32 GTS-T?

I ask as the old crown wheel is marked and I decided to not change it (to save $$$)but it still wines a fair bit so if I can get a new gear set it would be nice.
