Well, I am glad to say I just joined this 4.083-club. I echo what the others have said. This is a good upgrade. What you'll loose on the top-end is not earth shattering, but I sure'd like to increase my top end to gain what I lost. In short I encourage this mod for any one having double thoughts about them.
Thanks to Adam@Z1Performance for hooking me up with the gears, the Carbonetic LSD, and the NISMO clutch!

If that is the case, I would want to put some kind of limited slip in with the 4.08 gears. The mechanical advantage of the 4.08 gears will generate more power and increase your ability to spin the tires. I would want to have some sort of LSD to make sure that the increased acceleration was going to go to both of the wheels.
The quaife is certainly the cream of the LSD units. I considered getting one, but with the stub axles it was a lot more expensive than the Carbonetics for me. You won't have to buy stub axles with a Base, so it will be a bit more cost effective for you.

Just make sure you break the diff in correctly and change the fluid as often as required.

I'd personally be more interested in a 3.9 because my highway mileage sucks enough as it is, not looking to buy anytime "soon." But end of the summer should have a little liquidity to play with.

Not that I can't afford an extra 2 mpg of gas, but I'm not going to be benefiting to that extent.
I'll send you an e-mail when I'm looking to do this, and availability will probably decide the gearing.

Trust me, real world city driving I get 18, if I shift at 2k and drive slow as ***** I get 20 city, not realistic or worth it.
Highway I get 27 at 50, I get 24-25 at 80. Again, not worth it.
2007 = 2008 mechanically, therefor I am assuming Nissan just posted the DE test results as HR test results because they are DEFINITELY wrong.
I've tried driving easier and I just don't get the EPA ranges, I could fine in my last car - so I know its not driving style.

I just bought the 4.08 pumpkin from Z_ology and he sent Mobil 1 LS 75W-90 synthetic gear oil (thanks again!). Anybody use this gear oil for the differential? Manual says 80W90. Any suggestions?
Thanks.
Also Z_ology your inbox is full...

I've read through the majority of this thread now, and I have one question that I'm trying to find a good answer for. I'm looking at a Nismo LSD w/3.9 FD for my 07 base model. Is the dealership the best place to get this installed? I tend to not like going to dealerships, but no one in my area seems to be able to tell me where I can go and get this done. Getting the LSD on the car is no problem, but it seems putting the 3.9 FD to the LSD is something most places can't/won't do. I know I've read a few people saying they went to the dealership in this thread though, so if that's the only option, I guess I'll go up there when I get this.
