Diff

[rb25_vl]

just wondering what the diff ratio is on a n/a auto r33 rb25de

i have a vl with std diff and a rb25de just wanna make it go a bit better and i thought the diff might play a part in this

[LO_R33]

4.0

turbos 4.3

I'm unsure about the N/A's but can clear up the turbo diff ratio's.

R32 GTST runs a 4.363:1 diff ratio.

R33 GTST runs a 4.11:1 diff ratio.

GTR's run the 4.11:1 diff ratio.

I would assume the N/A's will run the lower 4.363:1 diff ratio.

Nah, The non turbos run 4.0, i can get a picture of my factory compliance card up if you wish:) Its tells you on there the gearbox codes and the diff...

Merry christmas everyone:)

I was assuming after all.

Merry Xmas... ho ho ho..

So the R33 N/A runs a 4.08:1 ratio.

The R200 comes in a variety of ratio's so we have plenty to choose from.

All that is required is a change of the crown and pinion.

Right from 3.7 (3.69 I think to be exact), 3.9, 4.08, 4.11, 4.363:1, 4.6 I think it was, I also do remember there was some even higher diff ratio's.

All parts are also very cheap.. Just a pitty there isn't as much of an option for the VL.

There is one option. The R31 runs a 3.7:1 and 3.9:1 ratio. Take your pic.

pintara's run 4.11:1 but the crown gear has 3/8" bolts whereas the skyline has 1/2" bolts...

Best bet is to head over to calaisturbo.com

They know the ins and outs of which diff fits what.

I do know a friend of mine is going to fit up a 3.9 or 3.7:1 diff ratio in to his VLT open wheeler depending on availability.

He prefers the 3.7:1 but 'may' end up going the 3.9:1.

I used Pintara 4.11 crown wheel and pinion on my aussie built r31 skyline with the borg warner diff . I fitted the crown wheel to the skyline centre . It bolts straight in ( bolt holes are the same ) . The skyline has 4 side gears as against the pintaras 2 . Also skyline has 28 spline axles , pintara 25 spline axles . My diff is open centre but i have fitted a mini spool which cost me $ 77 new . I,m not sure about axles for a VL think they are 25 spline with the turbo model having 28 spline , i may be wrong .

By the way my engine is rb30de , and was happy with 3.7 gears , but i just wanted better times at the drags , hence the 4.11 mini spooled diff .
