Did you just say Ferrari F430? The answer is
NEVER! You Z will NEVER outperform a Ferrari F430. Please never throw such comparisons. You comparing 370Z to a Ferrari F430 is like comparing Chevy Cobalt to a Corvette ZR1!!!
As for making your car FASTER, there's plenty of different approaches. The bigger questions are "How much do you want to spend?" and "How Fast do you want to make it?" Someone who is a car noob (is this your first sports coupe?), I'd stick with Exhaust/intake/tune/better braking (gripper pad) etc. 332 HP should be plenty of power. Many of us Z owners are VERY happy with the stock power and handling. Just my
of course.
