Founder & CEO

Colin MacCallum

Hey, I'm Colin MacCallum aka. Opie, the founder of Ronin Performance Engines. I've been in the engine building business for over 15 years, and during that time, I've worked at countless service and performance shops. I've honed my abilities to build extremely tough and fun cars that exceed expectations. My passion for high performance engines led me to specialize in Subaru's, although I love all kinds of vehicles.
