This is a direct bolt in High output alternator option for the Honda S2000. The stock unit is often not up to the task of powering extra loads such as large/multiple fuel pumps, cooler pumps, evac pumps, and sound systems while maintaining proper charging voltage. We have been testing this setup for over a year with perfect results and it is now ready for public consumption. Featured here are 170amp and 240amp options. Both have a 6 phase hair pin stator with a HD GM regulator. Comes will all mounting hardware, belt for A/C or non A/C, and a plug & play harness that will work with your oem Honda S2000 alternator connector for a SEAMLESS install.
