Brent Coles sent his Mazda RX-8 roller to the talented builders at Spot On Performance in Slacks Creek, QLD, Australia for a big transformation. In the engine bay they installed a built LSx V8 with a LSA supercharger producing 850 hp (634 kW) to the hubs. Behind that is a Turbo 400 three-speed automatic transmission sending power to a full-floating 9-inch rear end. Spot On Performance fabricated a custom rear suspension and chassis to help the supercharged power reach the ground. Watch the dyno run below or view more progress photos in the build album.

The owner said 4.2 liters in the video and we just included it without thinking. We’ve removed that from the article.
