94-02 Dodge 5.9L Cummins Fleece 63mm HX35 Cheetah Turbo

The HX35 turbocharger is a popular choice for the 24-valve Cummins engines from 1994 to 2002 due to its reliability and performance in stock applications. However, upgrading to the Fleece Cheetah turbo can offer several benefits, particularly if you're looking to enhance your engine's performance. Here’s why you might consider upgrading and what other components you may need to upgrade as well:

Reasons to Upgrade to the Fleece Cheetah Turbo:
Increased Performance: The Fleece Cheetah turbo is designed to provide a significant increase in airflow over the HX35. This can result in higher power output and improved throttle response.

Better Turbo Spooling: The Cheetah turbo is known for its fast spooling capabilities, which can reduce turbo lag and provide quicker power delivery.

Durability: Fleece Cheetah turbos are built to handle increased boost pressures and are generally more robust, making them suitable for high-performance applications.

Engine Efficiency: With better airflow and efficient spooling, your engine can operate more efficiently, potentially improving fuel economy under certain conditions.

Additional Upgrades Needed:
When upgrading to a high-performance turbo like the Fleece Cheetah, it’s important to consider other supporting modifications to ensure reliability and maximize performance. Here are some recommended upgrades:

Fuel System Upgrades: To take full advantage of the increased air provided by the Cheetah turbo, you'll likely need to upgrade your fuel injectors and possibly your fuel pump. This ensures that your engine can deliver more fuel to match the increased air, essential for higher power output.

Exhaust System: Upgrading to a larger diameter exhaust system can help reduce back pressure and allow the engine to expel exhaust gases more efficiently, complementing the turbo's performance.

Intercooler and Piping: Upgrading the intercooler and associated piping can help reduce charge air temperatures, which increases the density of the air entering the engine. This is particularly important for maintaining performance and engine safety under high boost conditions.

Engine Internals: Depending on the level of boost and power you are aiming for, reinforcing engine internals such as pistons, rods, and bearings might be necessary to handle the increased stress.

Tuning: Proper ECU tuning is crucial when upgrading your turbocharger. Tuning will help you optimize the air/fuel ratio and timing to take full advantage of the new turbo's capabilities and ensure smooth engine operation.

Transmission: If you are significantly increasing power, your transmission might also need upgrades to handle the additional torque. This could include stronger clutch components or a more robust automatic transmission build.

Considering these upgrades ensures that your engine not only performs better but also operates reliably under the new demands placed by the Fleece Cheetah turbo. It's a good idea to consult with a professional tuner or a mechanic who has experience with turbo upgrades for Cummins engines to get personalized advice and installation.
