You are looking at a John C Garage exclusive drop in S300 kit for the L5P Duramax! The only size we have available is the S369 and do not plan to add any other sizes at this time. We have confirmed fitment for 2017-2023 Duramax L5P 2500/3500HD. This S300 turbo kit is designed to drop in place of your factory L5P turbo with no real modications needed. The 2020+ L5P OEM Turbos do have a different Intake air temperature sensor than 2017-2019. This S300 comes threaded for the 17-19 IAT sensor. If you have a 2020+ L5P, there is a threaded port on the compressor cover you will have to block off. We use GM 12625041 to plug that port which is the OEM 17-19 sensor. You will also have to repin the VGT dummy plug for the 2020+ L5P.
The 69mm is ideal for stock injectors or even upgraded fuel system! It is capable of power in the 750-800hp range with supporting mods.

Commonly asked questions:
Q. Will I need a tune revision to run this turbo?
A. Yes, you absolutely will since this is a fixed geometry turbo.
Q. How long does it take to ship my S300 kit once I place the order?
A. Depending on powder coat options, it can take anywhere from 15-25 business days to ship. If you need something sooner, raw takes around 15-20 business days to ship.
Q. I already have a 3.5" down pipe and intake horn for my factory turbo, can I reuse those?
A. No you cannot. The intake horn and 3.5" down pipe in this kit is specific to the S300 turbo! The flanges are different from the factory VGT turbo and this S300 so that is why we sell this as a full package.
