As a rule of thumb no automotive manufacturer is going to purchase anything unnecessary and if they can save a little money here and there; as they are business of making money, not spending it. Making an assumption the reason Nissan uses the more expensive dual mass flywheel is because the transmission with rattle in neutral and be noisy with a regular single mass flywheel.

Another potential drawback of replacing the heavier dual mass with a lighter single mass is if you think the car is tricky to drive now, just wait till you have a 10 pound aluminum flywheel. Great for racing, horrible for street driving. What is your intention for the car?

I've had two dual mass flywheels resurfaced, the first worked great but the second went out early. Maybe it's because of a pretty large cam (245/248 with .630 lift) whose rough idle chews up dual mass flywheels or it was the resurfacing. Frankly not sure. There are sources on the internet whom guarantee their work in resurfacing them though.

Betting money also Nissan does not manufacturer the flywheel. Guessing a German company (Luk) probably makes them as they do for the C4 Corvette and many other European cars. Before you replace your flywheel from Nissan, I'd certainly check out a good Luk distributor as you may get it for about half price.
