This Smeding Diesel S300 3rd Gen Location Turbo Kit is designed for 2003 - 2007 Dodge Ram trucks with 5.9L Cummins engines. It comes with everything needed to install an S300 series turbo in the OEM location. Key features include improved performance and reliability, a proven fixed - geometry S300 platform, higher boost potential, reduced EGT, and a high - flow T4 divided exhaust manifold for quicker spool up. The system retains the factory air intake, downpipe, and intercooler piping and supports higher horsepower (650+ HP depending on the turbo). Most customers see a 1 - 2 mpg gain. It includes an Smeding S300 series Turbocharger, a 3 - piece exhaust manifold, a 4' down pipe, a 4' air intake kit with an S&B filter, oil feed and drain lines, intercooler piping, and other necessary parts. Note: This kit comes with a 3rd gen t4 manifold (no EGR ports) and is an emissions - off product for 2007.5 - 2018 Cummins. For 2007.5 - 2018 models, a full EGR is required. 2003 - 2004 model year (305HP output) Dodge Ram 2500/3500 with HY35 turbocharger need a 2004.5 - 2007 style aftermarket downpipe like Flo Pro part number 20811 and OEM V - band Part# 52121285AA. All Smeding Diesel Parts are built to order in Texas and may take longer for fulfillment. All turbo kits come with a standard thrust bearing; if you want to upgrade, select the thrust bearing upgrade. Also, make sure to choose your turbocharger size. Call us at (778) 754 - 7090 if you have any questions or need a different turbocharger.

Using this Smeding Diesel S300 Turbo Kit is straightforward. First, make sure you have all the parts included in the kit: the S300 series turbocharger, exhaust manifold, downpipe, air intake kit, oil lines, intercooler piping, and other misc parts. Check the model year of your Dodge Ram and the engine type (5.9L Cummins). If you have a 2003 - 2004 model with 305HP output and a HY35 turbocharger, get the recommended aftermarket downpipe and OEM V - band part. For 2007.5 - 2018 Cummins, install the full EGR. When installing, follow the standard procedures for turbo and manifold installation, connecting all the pipes and lines correctly. As for maintenance, regularly check the oil feed and drain lines for leaks. Inspect the air intake filter and clean or replace it as needed. Also, keep an eye on the turbocharger's performance. If you notice any unusual noises or a drop in performance, it might be time to have it checked. And don't forget to select the right turbocharger size for your needs.
