what are the most important mods for me to do right away i just bought my car and i want to add more horse and more power feels a little sluggish .......i have an automatic but i want to give it zip ..........some one help!!!!

 

I don't have a Z yet but am looking at NA's. The list I plan on doing, performance wise follows.
1. JWT Pop Charger
2. Unorthodox Underdrive Pulley
3. Cat-Back Exhaust (maybe stillen or greddy)
4. HKS ALC II
5. JWT ECU
6. Stillen Headers
7. Cams
8. Aluminum flywheel
9. Ignition upgrade
10. unknown put NOS last on my list

 

so far i have
1. jwt intake
2 stillen exhaust
3. hks alc
4 u/d pulley
5. brake upgrade(definitely a must, the z can get really scary)
6 ultimate upgrade(plan on doing a jdm tt engine swap soon)

definitely noticed the difference with the 1st 5 mods. i really recommend doing the brakes. remember, upgraded engine requires upgraded brakes
