Industrial Injection 03-07 5.9 Cummins S300 SX-E Single Turbo Kit 62/68 w/ 1.0 A/R

Industrial Injection is well-known for their performance diesel parts, and this S300 SX-E Single Turbo Kit is a prime example of their work for the 5.9 Cummins engine found in 2003-2007 trucks. This kit is designed to replace your stock turbocharger with a more capable unit, helping your engine breathe better and make more power. If you're looking to improve your truck's performance, especially for towing or competition, a turbo upgrade like this can make a significant difference.

This kit features a BorgWarner S300 SX-E turbocharger with a 62mm compressor wheel and a 68mm turbine wheel. The compressor housing has a 0.68 A/R (Area/Radius ratio), which helps to improve airflow and responsiveness. The exhaust housing has a 1.0 A/R, which is suitable for a wide range of applications and helps to spool the turbo efficiently. This setup is a popular choice for those looking for a noticeable increase in horsepower and torque without going to an overly complex compound turbo system. The kit includes the turbocharger and necessary components for installation, though you'll want to consult the manufacturer's instructions for a complete list of what's included and any additional parts you might need for your specific truck.

Keep in mind that this turbo kit is not CARB approved and cannot be shipped to California. For other states, this kit offers a solid path to improved performance for your 5.9 Cummins. It's a substantial upgrade that can change how your truck performs under load.
