2015 nismo
 

what makes the 15' nismo different performance wise? have they up graded intake manifold? was looking at the Z1 manifold but, don't wanna "upgrade" if nismo has a better one or comparable. Im not sure what they did to the nismo to make more HP, im guessing tune, exhaust and nismo labels everywhere.<<<last part was a joke.....

The nismo's extra power comes from a slightly less restrictive exhaust. The 15 also has a slightly different ratio in the rear end for a little extra acceleration.

yeah I knew about the 3.916 final drive and exhaust but 25 more over the sport seemed like more than just exhaust. ive been comtemplating the Z1 400hp package since I have a nice exhaust already. this would just compliment it nicely I think.

What speed do you cruise at with that final drive with your rpm at 3k and 6th gear? I have 14 Nismo, and I was contemplating switching to 3.9 gears but don't want to be at 4k rpm at 80mph

don't forget about the red accents. That adds hp too

3k rpm is 72mph, 3.5k rpm is 85mph, 4k rpm is 99mph.:driving:

honestly the red is fine for a little while....im over it and will be changing the whole look soon.....

Thanks! That will help me with my decisions.
