NA or SUPERCHARGED

Quicksilvers

Depends on what supercharger head unit you have? The Stillen tuner supercharger kit is expensive to begin with. Depending on if you want to upgrade the head unit it could be between 1K-2Kish just for a basic rebuild from Vortech on the standard V3. With no upgrades to the Stillen supercharger kit and not properly tuning this set up by a reputable tuner you will be running on barrowed time and opening up Pandora’s box. Unless you have the extra coin set aside to replace or rebuild your engine you should not have a supercharged Z to begin with. You should start off with a stock clean naturally aspirated Z and go from there. Definitely search this wonderful forum here and take the time to read about your Z. Good luck.
