The 2006 AEM/DC Sports Civic Si is built to compete in a series of road racing track events including the up and coming Time Attack events. As with every vehicle AEM has built in the past it is used as a test bed for AEM and DC Sports products. AEM claims this Civic Si features a 400 horsepower engine thanks to a custom turbo installation using a DC Sports exhaust system, Garrett GT28RS turbocharger, Wiseco pistons and RC Engineering injectors. An Advanced Clutch Technologies flywheel and clutch transfer power to the ground. Suspension enhancements include Eibach springs and anti-roll bars, SPC Performance control arms and Tokico shocks.
