The Smeding Diesel S300 Turbo Kit is a complete performance upgrade designed for Duramax 6.6L trucks. This kit allows you to install a high-flow S300 frame turbocharger on your Duramax using most of the factory components, providing a direct bolt-in solution that improves airflow, reduces boost restrictions, and unlocks significant power potential when paired with proper tuning.

Unlike restrictive stock VGT turbos that can choke airflow and generate high drive pressure, the S300 kit delivers better exhaust flow and lower drive pressure for stronger performance and healthier engine operation. Whether you’re building a tow rig, daily driver, or high-performance truck, this kit provides an excellent balance of power, reliability, and value.

FEATURES & BENEFITS:

  • High-Flow S300 Turbocharger: Offers improved airflow over the factory VGT turbo, helping to increase horsepower potential and reduce backpressure. 
  • Direct Bolt-On Design: Works with the factory intake, intercooler pipe, and up-pipes in most setups for a straightforward installation.
  • Complete Hardware Kit: Includes T4 pedestal, downpipe, oil feed and drain lines, coolant plug, gaskets, and necessary mounting hardware for a full installation. 
  • Cost-Effective Upgrade: Offers a high-performance alternative to expensive VGT replacement turbos while delivering better exhaust flow characteristics. 
  • Versatile Power Options: Available with multiple turbo sizing choices, allowing builders to tailor power potential for towing, hauling, or performance. 

KIT CONTENTS:

  • Smeding Diesel S300 Turbocharger
  • T4 Turbo Pedestal
  • 3.5″ Downpipe (Fits factory or aftermarket exhaust)
  • Oil Feed Line
  • Oil Drain Line
  • Coolant Plug
  • Gaskets & Miscellaneous Hardware

This S300 Turbo Kit provides a solid foundation for increased power and performance on your Duramax 6.6L, with a robust design and quality components that make installation and future tuning upgrades easier and more effective.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.

Good to have if you've never seen the iTEP exam, but don't rely on it to boost your scores
Format: Paperback
This book is good in that it comes with two practice tests: one in the beginning of the book, one in the end of the book. The grading rubric is helpful too. However, the actual guide part of the book, doesn't help too much with how to improve test scores. What I like least about this guide is that it won't tell you which questions you answered incorrectly on the practice exams. A good test prep guide will tell you what you answered incorrectly, and will tell you what logic to follow to get to the correct answer. In the reading passages, it would be nice to know where I can find evidence to justify the "correct" answer. In the grammar section, it would be nice to know which rule I'm violating. Any test guide should always come with some testing strategies. I.E. If this question is taking up too much time, skip it and go to the next one. This guide lacks simple strategies like that. Simple strategies like that could be useful when incorporated into this guide because there are certain sections on the exam that you can go back to previous questions, but some sections where the "back" button is disabled. Overall, if you've never seen an iTEP exam before, this book is certainly helpful in that it will give you an idea of what you will be testing for. However, this book alone won't help you achieve a score of 6. The table of contents itself will tell you there are only 86 pages of actual content covering test material. That's not enough to cover how to excel in the exam.
