Changing turbo diesel diffs to the V6 petrol ones

Hey guys,
has anyone tried swapping the diffs in the d22 from diesel(smaller) diffs to the 3.3 v6 diffs (bigger), allowing the truck to crawl slower if i am not correct and also allowing me to fit a air locker to the front.
just an idea i had cause i would rather have a air locker in the front rather then the back.
Thanks Luke

Dunno about that but as to the air locker, I didnt know they wouldnt fit. Is that a fact or a suspicion? 4WD Sysytems do an auto lokka for the front diff only on the D22.

EDIT: Come to think of it Changing the diff ratio's would affect everything, not just the crawling speed. The cruise speed would also be a crawl. So to speak.

the early petrol models are the same ratio as the diesel and the front diff can be swapped over. there is no air locker for the r180 but there is for the c200.

i havn't looked at the later petrol diff ratios. not sure what the effect will be. but the rear diff is h223 (?) which is very strong.
also look at the diffs from the QD32 (3.2 diesel) utes. gutless motor but strong diffs, go fiqure!

If you want a higher diff ratio get some D21 crown wheels and pinions out of certain models - 4.88:1. Doesn't get much better than that.

EXCEPT ON THE HIGHWAY WHERE IT SUCKS.

I can't get past 135km/h because the motor just won't spin any faster.

thanks for the replys guys i don't know much about this sort of thing just thought it could possibly work
Cheers Luke

If I could fit 35s it would be problem solved.

There's an R200a on fleabay in Shitney, somebody buy it.
Pathfinder WD21 front Diff - eBay Differentials, Transmission, Car, Truck Parts, Cars, Bikes, Boats. (end time 16-Oct-10 13:32:28 AEDST)

VG33E = 4.636. H233B rear diff and R200A front diff.

VG30E = 4.375. H233B rear diff and R200A front diff.

ZD30DDT = 4.375. C200 rear diff and R180A front diff.

QD32 = 4.636. H233B rear diff and R180A front diff.

YD25DDTI = 4.375 and 3.9, same diffs as the ZD30DDT.

Hi Dave

And A D21 Z24 HG46 has ??

HG means H233B rear and the front will be the R180A in 4.636 diff gears.

CA43 would mean C200 rear diff and R180A front diff. 4.375 diff gears.

Only the V6's got the R200A fronts.

The vg33e came out with 4.6's aswell.That is what I have in mine now.

Thanks for the info Dave.
So if i was running 33's the v6 diffs wouldn't be too bad would they?

Did any model Nissan come out with 3.7 or 3.9 in the H233B or the R200 diff whether i be skyline or patrol or anything else

34"s I reckon would bring it back to standard pretty much.

Scott whats your compliance plate say ?

Use a 3.9 from an auto petrol Patrol for your rear H233B, and a 3.9 from a D21/D22 4x2 C200 rear diff in the front R200a.

4.6's Dave.I'm on cloud nine at the moment.I have had my pain relief tablets increased.first day and I'm a space cadet.lol I'm f@#kin flyin

Commodore in the v8 ran 3.7,s so I thought if I run 3.9's to compinsate for the weight differance it should be pretty good.In the videos posted at glass house by Raywise I was in 4 high all day.There was no need for 4 low.

No worries Scott.

You could almost go 4.1's as the Navara tyres are bigger.
