Ok guys,

I'm working on a solution for the X guys being able to swap out our Final drives. It looks like according the the FSM the front diff is a type 160A. Does anyone know if the older Skylines ( R33 or R32's) used theses? Or the Stock Xtera's ? Needs some help please

Diff is F160A ?

 

Wow that's cool somebody is trying to tackle this. Please keep us updated. I was to pissed when I found out I couldn't do a final drive swap with the awd

 

Still nothing on my end, Cant find any place to do this

 

Awesome R&D on our AWD platforms! Hope it works out!

 

Yea it didn't I've been at this for 3+ weeks and nothing. I'm out. We just have to deal with the fact that we can do sh#t about it Sux man really does.

 

3.69 is still an option

 

I read that the r35 has the same front differential.

 

Yea the 3.7 is the stock G35X , and I read the same thing about the R35 just trying to get someone to say 100% I have a email in at os Giken Japan should no tomorrow.

On the 3.70's no even sure it be worh it I couldn't find any info on anyone anywhere that swap from 3.36 to 3.7's :/

 

That should still be a noticeable jump though. People that go to 3.9 love it so I don't think 3.7 would be far off

Thanx man!

 

Going off the fact that 2007 g35x's have a 160a final drive...

See pg 144

and that all 2007 sedans (and sedans only based off the tech spec's I've found, as I know as coupes had different FD specs not worth swapping) were spec'd with 3.69 FD gear ratio.

It seems swapping the rear pumpkin from a 2007 g35x sedan would be the best candidate for a straight forward, PnP differential swap (might as well upgrade to whiteline bushings too). 3.3 > 3.69 is a nice bump for off the line performance and applied torque in lower gears.

If you look back at 2006 and before final drive ratios, there's nothing worth swapping from. I'm not all that familiar with AWD specifics or the in's and outs. I'm basing a lot of this off my own RWD based 3.3 > 3.69 diff swap that was out of a 2007 G35S sedan that had 60k miles on it. I was able to get it off ebay for $200 shipped. After new fluid, Whiteline bushings and install.. best. mod. to date. Hand's down and that's based off 3 car's worth of modding history.

2007 was a unique year for across the board 3.69 use on sedans. Sport models added vlsd, but no gearing change on either 5AT or 6MT's. My understanding is that all awd equipped rear diffs are vlsd variety. I could be wrong on that, nonetheless...I'd still imagine that '07 G35X would be worth searching out due to unforeseen differences (you could prob figure that out from the service manual section linked to above) between a rear diff out of a AWD and RWD model.

For additional reference, G35 guys six years ago were discussing this topic as they were looking into potential donor options and a few details,

Pretty decent price on a potential option for you X guys... but it does have 80k on it..

Oh damn forgot to post here also, This is a ZERO go, You'd have to pull the motor to swap the front diff , Unless you buy a used front diff and swap the guts , theres no option for us ;/ Sux, the GTR front diff is the same but there are only 3.3 gears for them

 

So can't you just swap a front differential from the g35 to make it easier??
