Offering some realistic advice:
For 1/2 of distance you could play around with a driveshaft spacer, similar to the Automatic donut, this is about an 1 in thick so technically you could bolt any OEM DS and work with the spacer.
For Intake, contrary to popular belief, they're nice but there is a bias. We have seen all sorts of intakes make good power. What you never see is an Admin tuned car with non Admin intakes making more power than his. We know his tunes get sauced. Asides from the fact that you'd have to drill them to install breathers. They'll reccommend you delete the PCV with their fantastic catch can setup (amazing marketing)
As far as EPS throttles go, no one tells you that there is rev hang at at high RPM, and trying to get this as minimal as possible can get expensive sending logs back and forth (Not worth the minimal power vs work and money)
For best results get some tuning components, line pressure can be adjusted along with other parameters, Shift logic cant but you'll have better luck with the ability to record a log and send it to others to determine what your car is doing.
Good luck!

@BULL I was wondering how much you'd actually get with the throttle bodies, it seemed pretty minimal when I did the bigger throttle body on my 03 G35, didn't think it would be much different on the 3.7.
As for the spacer, you need to reduce the driveshaft by 1/2 inch not increase.
And, as far as admin intakes go, there is for sure a bias lol
It's a 3 inch intake just like alot of them out there, and paired with K&N filter, so it can't be that much better, if it's better at all. But the price point is competitive. Also, as far as cutting to make it fit, that is not a major concern, that will be one of the easiest parts of this project.

I still believe we can find the right 2 piece drive shaft, plenty of models to choose from just have to trial and error. Essentially you'd want a shorter shaft that you can adjust with the spacer
As far as intake go, well you have my opinion. I'd hate to buy something at this price range then wait then have to modify.

You can't get away from the hanging of revs even if it's minimal.

And I really like the one piece, you do save some rotational mass, same with lightweight pullies, which I already have installed. I've read both sides of the arguments for and against those, but I've enjoyed them on the G35 and now the G37. Had them on for about 40k miles with no issues.
Also, I appreciate the advice on the intake, ill keep looking into it. Any suggestions? Soho seems to be good, and I'm definitely going with they're single exit exhaust and y-pipe. I live the tone it has, even better than the extremely over priced Tomei.

I've heard of another option that supposedly fits perfect, but it was through alot of threads, and the guy was from Puerto Rico I believe. He was having trouble finding a driveshaft at all.. it was from a completely different car, not even Nissan. If I come across it, I'll link the thread.
We're known for unorthodox fixes to problems. We're used to no aftermarket support. Technically there are hundreds of shops that specialize in this, All you would need is would be the Yoke and flange and the rest is a tube.

I keep hearing of VQ carbon customs. It really all depends, are you one to put something together or prefer the comfort of bolting something on?

SOHO's are really nice (69mm or about 2.71 inches). I just don't like the fact that the Admin intakes aren't solid piping through the radiator support. It's the coupler going through. There are other good 3" intake out there where piping is solid through. The nicest ones I've seen lately are from Miami Z Parts (check Instagram). Other companies that make 3"; RZG, Mike Upton, Real Auto Dynamics, Limp Mode Tuning, Unique Motorsports (UPT intakes). Market is flooded with them now.

Looking to do this swap. Right now I have a carbon fiber drive shaft that I purchased with EPS Tuning. I know I have to cut 1/2 inch off but does it matter which end?

I would think that that decision would be up to the driveline shop. I don't think you can do it at home...

To my understanding a Crown Victoria aluminum drive shaft will work as far as length goes but the end flange from the Nissan has to be adapted to it.
Easier than getting a custom one done.
Another plus is that is already aluminum and plenty of Vic's running a ton of power on these shaft's
