vr4 rs 3.9 ratio into ggsr (quick Q)

[mattrat]

hey guys as above there wouldnt be any probs with the above going into my ggsr if it was locked to FWD should it. IE the ratios only effect the rear diff?

 

[GVR40]

so u want to put the complete box in?

there will be no problems just have to lock it into FWD and you may find the gear ratios will be different

 

[mattrat]

yer sorry complete box..
ratios wont bother me just hoping my driveshafts etc. will fit?

 

[265T]

do you have the RS box already?

 

[bazeng]

would a 3.5 ratio be better for a fwd based on longer 1st 2nd and third for less wheel spin, but yes. Just lock the centre diff be you'll be right

 

[CLuTZ]

I have 3.909 in my RVR and HATE IT.


3.545 FTW!!

 

[mattrat]

really... nah dont have the rs box yet whys that?

 

[265T]

thought it might have come with the RS engine

 

[mattrat]

nah he already sold the gbox...

 

[265T]

nah he already sold the gbox...

was it an rs box?

 

[mattrat]

culdnt tell ya
soz

Hey Bazeng, doesn't he need to weld the viscous coupling thingy as well?

 

[GVR40]

no mahommed, he may need a viscous centre eliminator, which is basically the same as locking the centre diff. the viscous coupling is the type of diff in the gearbox to send drive to the rear end

 

[MDK87]

Umm, ok. I'm really confused now. (Sorry to clutter your thread Matt, but this may prove handy to you aswell).

Craig, I thought the viscous coupling was the thing in the first pic? (This one is welded obviously)

And the centre diff, is the thing in the second pic?
Does the thing in the second pic need to be welded up aswell?

I wanna get this issue sorted out as well hey, I have no idea what needs to be done to lock the AWD box to FWD. I've spoken to a fair few people about this, and each one has had their own unique opinion, and I can never derive a straight answer from them. :?:

The guy thats putting my box back together told me that, because my viscous coupling (thing in the first pic) is already welded, the centre diff. (thing in the second pic) doesn't need to be. But now you guys are saying it does :shock: ............I hope he hasn't put my box back together yet!!
He sorta looked hairy fairy about it to start with, but seeing that he was a gearbox rebuilder, I assumed that he'd know what needs to be done, so I left him with it.

Any help would be much appreciated. (I'm sure you'd too Matt, because I bet that KM206 won't last long with your new motor. :wink: )
Thanks.

3.9 is great for fuel economy around town but shit for highway driving!

 

[DOUGMO]

the top one is the viscous coupling(centre diff)

the bottom one is the front diff which does not need to be welded.

 

[rob323]

I can see why there is some confusion here. The bottom pic is definately the centre diff, the front diff is huge in comparison.

The viscous coupling, centre diff and front diff in a vr4 (eg W5M33) are totally separate parts and should not be construed to be the same. I have a pdf of a sectional view through the box but can't upload it unfortunately (happy to email it to anyone who cares).

 

[MDK87]

So Rob, would the thing in the second pic need to be welded up for a FWD conversion?
