Basic rule is that for every 100 lbs you shed, you lose a tenth of a second in the quarter under perfect conditions. Assuming you have a DE motor, they don't respond too well to bolt ons. Full exhaust, your butt dyno might feel a little faster in the higher rpm range. Basic bolt ons though dont do the 350 any justice.

Go fast or look fast pick one. I would save all your benjamins and go with FI or engine swap if you want real power. If you want to save money but want a little something than get a revup air box with high flow filter, Do a set of HFC, Y-pipe and exhaust. Spend the rest of the money on Suspension and brakes. When you hit a jackpot pick up a SC / turbo kit or throw the VQ motor in the trash and put something decent to begin with in the engine bay.

Just to let you know. The 350z hood is made out of aluminum. And very light as is. Getting a Carbon Fiber hood is not going to make a difference at all. You might lose 1 or 2 pounds.
If your really looking to lose weight, look into kevlar products.

CF hood is usually a 1/2 pound loss to even a gain, we are not driving honda's. The seats are heavy as hell, a nice weight loss is putting in some quality race seats.

OP, stick with stock hood as mentioned.
Go fast or look fast pick one. I would save all your benjamins and go with FI or engine swap if you want real power. If you want to save money but want a little something than get a revup air box with high flow filter, Do a set of HFC, Y-pipe and exhaust. Spend the rest of the money on Suspension and brakes. When you hit a jackpot pick up a SC / turbo kit or throw the VQ motor in the trash and put something decent to begin with in the engine bay.
Look fast or go fast. Aesthetics and bolt ons vs FI.
+10000000 for this comment.
I get a lot of schit from my homies who make fun of me because they've been with me since the day I got my Z.
It's EASY to put a good 7-8 grand with basic bolt ons and aesthetics.
Does it make your car any faster? Barely.
FI all the way.
