Increase performance and lower EGT's from your 2004.5-2005 GM 6.6L Duramax LLY with the HSP LLY Add-A-Turbo Kit Corner Mount (No Turbo). HSP has designed these Add-A-Turbo Kit's to bolt-on an S400 frame turbo of your choice to your existing factory VGT turbo, meaning zero cutting to your truck for fitment! While the factory VGT turbo is great for bottom-end torque and quick throttle response, it runs out of steam for top end power, causing high EGT's. The addition of an S400 frame turbo will not only lower your EGT's but also broaden the power curve and increase fuel economy while being capable of 600-850HP! Batteries remain in their factory locations for large amperage draws and reliable cold starting.
- Lower EGT's
- Supports 600-850HP
- Broader Power Curve
- Complete Bolt-on Installation
- Adds An S400 To Existing Factory Turbo
Note: Requires an S400 frame turbo and aftermarket custom tuning and supporting modifications for installation (not included).
