VGT/S300 Triple Turbo Kit for 2001-2016 Duramax are designed to compound charge your OEM or Modded VGT (or IHI) turbo with TWO atmosphere Turbo chargers, typically s300 frame size. These Kits offer instant Spool Up characteristics the same as an s400/Stock compound setup, but even quicker engagement from the atmosphere air supply. With Modified VGT's you have the capability to exceed 1000 RWHP and still attain great street manners, or you can run this kit with stock fuel on a stock bottom end engine. Kits are available without turbo chargers but we will need to know what you are planning to use, and in some cases, may need your turbos sent in for the build process.
