Duramax L5P S400 Turbo Kit - 2017-2019 Silverado/Sierra

Duramax L5P S400 Turbo Kit - 2017-2019 Silverado/Sierra

***We have these kits in stock with no lead time! They are already built, powder coated, boxed, and ready to ship***

 

Please read this full description as it is filled with a ton of information and details! At the bottom you will find commonly asked questions as well.

 

Fits all 2017-2019 Duramax L5P 6.6L Diesel 2500/3500HD Pickup trucks!

 

Will we have a kit for the 2020-2023 L5P Pickup trucks? Unfortunately we won't. These 2017-2019 kits can be modified to work on the 2020+ L5P however it does require custom fabrication to the driver side intercooler pipe to clear the ECM. If you do plan to go this route, it's best to buy the matching driver side pipe (if you don't have one already) HERE and use this to connect to the S400 driverside intercooler pipe. You cannot run the airbox provided in this kit as it will not fit and line up with the ram air from the hood scoop. You will also need to repin the provided VGT dummy plug. Not practical for a DIY guy but an install shop can manage to make these changes. We do offer a drop in series S300 kit which works great on the 2020+ trucks too and does not require the modifications to the hot side. John C Garage S300 Kit

 

Here is our suggestion for turbo choices,

S463.5 (AKA S464) (63.5mm/83mm/.90 A/R T4) Stock fuel system 650-700HP

S467 (67.7mm/83mm/.90 A/R T4) Stock fueling or smaller fuel setup 800HP

S472  (72mm/83mm/.90 A/R T4) 50% - 150% Injectors and 10-14mm CP3 850+HP

 

The colors listed are the only options we have available and we do not have the ability to get any other colors. If you want a different color, grab a kit and get it repowder coated. We have done this several times and any powder coat shop can easily do that.

 

There will be no turbo included with the base installation kit (first photo) but can be found in the suggested item list below.

***COMMONLY ASKED QUESTIONS***

 

Q: What colors do you currently have in stock?

A: The colors listed in the 'Powder Coat Color' drop down menu that you are able to select is what we have on hand, ready to ship. This is always updated and real time inventory with what we currently have. The colors that are unselectable are what we have in production and could take anywhere from 6-8 weeks for us to have available again.

 

Q: Can I order this kit raw? 

A: Under no circumstances are we able to ship a raw kit that is not powder coated.

 

Q: I am looking to piece together an S400 kit and don't need everything you are offering in this listing. Do you sell the individual components?

A: No we do not.

 

Q: I often times see listings on the internet that are old and outdated. Do you actually have these kits?

A: We sure do and have a very solid reputation for having hard to find parts in stock!

 

Q: How long does standard shipping take?

A: All kits are located here in Pennsylvania so figure 1-3 businesss days from the time the order ships for east coast to mid west. 3-5 business days for central to west coast. If you select the optional turbo, that ships from our vendor so that will usually show up after the installation kit.

 

Q: Do I need a tune revision to run an S400 Turbo?

A: Yes, you certainly do.
