Show original supplier description
The MMI Speed Shop Twin-Turbo-Kit-Vortec offers a complete, direct bolt-on solution for adding significant power to your 2007-2013 Chevrolet Silverado or GMC Sierra equipped with a 4.8L, 5.3L, 6.0L, or 5.7L V8 LS engine. This turn-key kit simplifies the turbocharging process, eliminating the need for custom intake or exhaust fabrication and hooking directly into your factory exhaust system. Key features include OEM quality cast exhaust manifolds and downpipes, and mandrel-bent TIG-welded aluminum intake piping for optimal airflow. The kit utilizes hybrid T3/T4 turbochargers and includes a bar and plate front mount intercooler with all necessary brackets. For a seamless installation, it comes complete with braided stainless steel AN oil lines and a feed adapter, along with all vacuum lines, PCV system components, check valves, clamps, and hardware. A significant advantage of this kit is its design to retain essential factory systems, including air conditioning, power steering, fog lights, the stock fan and shroud, and all stock sensors. It requires no cutting, hacking, or relocation of any components, not even the battery, making installation manageable for the average enthusiast over a weekend. With boost starting at 8psi, expect horsepower to easily reach the 500s on a 100% stock drivetrain. Note that this kit is intended for racing vehicles only and is not for sale or use on public highways in California and New York.
