This slick new Heritage GT S197 twin-turbo setup by Team Performance Products [(888) 990-TEAM; www.team-ppi.com] is a hands-down winner when it comes to clean engineering, as the ultra-sano kit installs without any need for cutting, welding, or modifying a new 'Stang's engine compartment. The system, designed for stock Three-Valve engines, is highlighted by a pair of Garrett 2871R ball-bearing turbos and a high-flow, air-to-air intercooler that together are capable of generating 440 rwhp and 465 lb-ft of torque at 8 psi of boost, using 91-octane pump gas.
