Among the upgrades done to Fathouse's top-tier performance package for the GT350 Mustang include forged engine internals, a beefed-up twin-disc clutch, a Motec ECU, custom intake and exhaust piping, stronger axles, and a carbon fiber driveshaft. There's also an upgraded oil pump, a thicker intercooler, and three fuel pumps to handle all that extra power. The shop sent us a ton of pictures documenting its build process, including photos of the custom exhaust needed to fit the turbochargers, which are mounted next to the transmission under the car.
