The LLY Duramax comes from the factory equipped with a variable geometry turbo charger. This turbo is great for quick response and bottom end torque. However, it falls short under heavy loads, or when other performance tuning/or programmers are used. HSP has designed an “add a turbo” kit that will give your truck a massive power curve, while not sacrificing the drivability of your factory VGT turbo. These kits are engineered to bolt directly into your engine bay with ZERO cutting or modifying of your truck. The factory VGT turbo, by itself, can cause dangerously high exhaust gas temperatures (EGT’s). To solve that, we paired it with a Borg Warner S400 frame turbo in addition to the factory unit. The results speak for themselves, including, lower EGT’s, increased better fuel economy in many cases, and an extremely broad power curve. Power levels will mainly depend on current modifications to your truck but can range from 600HP to 850HP. This Corner location coolant tank kit requires the removal or relocation of the 2nd battery. Many choose this style kit because they like the look of their engine bay without the second battery or have previously relocated it elsewhere in the truck. To keep both of your batteries under the hood, check out our other “add a turbo” option which keeps them in the factory location! (213-HSP)
**Capable of 650HP+ depending on tuning and fuel system options, This kit requires the second battery to be removed or relocated on the truck.
