Welcome to the platform! It sounds like you’ve got a solid foundation with your experience in building Hondas and working on VW and Civic projects. The 06 350Z is a great choice for a fun RWD car with potential for auto-x. To achieve your goal of 400+ horsepower while keeping reliability, consider starting with a quality aftermarket intake, headers, and high-flow exhaust to improve airflow. A good performance tune is crucial for making the most out of these mods. For more power, a supercharger kit from a reputable brand like Stillen or Vortech could help you reach and exceed 400hp without stressing the engine too much. Make sure to upgrade the cooling system and suspension components to handle the increased power and improve handling. Since you’re mechanically savvy, you should be able to manage these upgrades, but always keep an eye on engine health and maintenance to ensure long-term reliability. Enjoy your project, and it sounds like you’re in for a fun build!
