From discerning enthusiasts with a passion for automotive excellence to collectors seeking bespoke masterpieces, our target market consists of individuals who have the time and resources to invest in high-quality builds done right. 

Our History

Powerhouse Performance was founded in 2017 in response to a growing need in Ventura County and its surrounding areas for a comprehensive automotive facility that could cater to a wide range of needs - from mild bolt-ons to high-performance upgrades, suspension enhancements to full-frame restorations.

As automotive enthusiasts ourselves, we recognized the frustration many car owners faced in having to visit multiple shops to fulfill their automotive desires. Thus, Powerhouse Performance was born, with a vision to provide a one-stop solution for all automotive needs under one roof.

At Powerhouse Performance, excellence is not just a goal - it's our standard. We take pride in our attention to detail, commitment to quality, and dedication to customer satisfaction. With state-of-the-art facilities, cutting-edge technology, and a passion for all things automotive, we are Ventura County's premier destination for automotive enthusiasts.
