I don't race, never been on track, nothing crazy, just want some more power with max 4500-5000RPM (never go beyond that) or better launch at some red lights or stop signs randomly. What mods should i do to fit my driving style, plenum spacer, exhaust or intake (i already have drop in K&N, everything else is stock), my goal is to get around 15-20hp more than current setup. How much do i expected to spent. Sound or look is not very important for me since the Z looks good stock though.

 

Your style of driving?

Or

Your ricer train of thought?

Change all the oils and get a tune!

 

How much you got to spend?
Intake,plenum spacer,exhaust,test pipes or HFC's.
A TUNE!
Will get you there.
Depending on how much work you do yourself,it'll
cost you $2,500+.

 

If you want more power, there is always the gas pedal. 5,000 RPM is when the engine starts hitting it's stride.
