Description

The MMI Speed Shop S550 Twin Turbo Kit Package is engineered for 2011-2023 Ford Mustang Coyote GT 5.0L V8 engines, offering a street-oriented twin turbo setup. This comprehensive package is designed to achieve up to 1000 horsepower when paired with complementary modifications. Included is a cooling system with a high-flow fan and an intercooler, alongside an electronic turbo timer that manages the engine's cool-down cycle to prevent premature wear and oil coking. The kit features two turbochargers with T3/T4 flanges, CAST turbo manifolds, and a front mount intercooler with a .57 compressor wheel trim. Additional components such as a fuel pressure regulator and filter kit, blow-off valve, T3-Vband stainless adapters, heatwrap, DIY downpipe kits, cone air filters, and a 52mm back-lit boost gauge are also provided for a complete installation. This package is designed to provide significant horsepower gains on a stock motor at a low boost setting of 8-10 PSI. The turbochargers are capable of producing over 450 horsepower each, featuring wet float bearings, balanced rotating assembly, 3" inlet, 2" outlet, .50 A/R compressor housing, .63 A/R turbine housing, and a 1/8 NPT oil inlet. The manifolds are TIG welded from 321 Stainless steel with 1 5/8" primaries and thick flanges. Some modifications may be necessary for 2015+ models.
