Hey man. It looks like you wrote this a long time ago. But maybe you're still wondering. I put the Fidanza flywheel in my Sentra. I have the 1.6. It weighs only 7 pounds and is awesome. My car revs so much quicker now. That's the main thing I noticed. As far as power and stuff, I'm not sure I noticed anything to drastic. But it sure is a lot funner to drive now.
