I would have to say this has to do with the gearing. The gearing on the
GA16DE is rather conservative, while the gearing on the SR20DE powered cars
are closer. You will notice that cruising on the freeway, the RPM's on the
Sentra SE are a bit higher than the RPM's on the GA16DE. I think this is
the cause of the noise.

Not that I know about.
