well you can definitely look forward to some aftermarket parts coming out for it, but thats all i can say right now
easy way to lose 30lb on the note is get rid of the spare...planning to do that myself this coming weekend...also later on going to get some lightweight rims to unload some rolling weight and maybe a lightweight battery...figure if i can get close to the power to weight ratio of a mazda mx-5 i'll be happyI agree, with taking out 250# of weight, I would have assumed they would include everything they could do to lighten up the Note. Gas tank is 10.3 gal US, so they took out two gal or 16 pounds that way.
Less weight with same power will make the car quicker and handle better. Of course mpg's will be up as well.
I have seen HR16DE's put down 115whp on dyno's with a couple of go fast goodies. Now that isn't alot but on a car that weighs 2,300lbs (after reduction) it has a decent power to weight ratio. I don't think you will get down into miata territory but it would still be a much more fun car then stock. Think classic Sentra SE-R stock.
