The Role of the Turbocharger
The turbocharger is an exhaust-driven forced induction device. It uses the engine's exhaust gases to spin a turbine, which in turn spins a compressor. The compressor then forces more air into the engine's cylinders than would be possible naturally.
This increased volume of air allows for more fuel to be injected, resulting in a more powerful combustion and thus, more power output from the engine.
The stock turbo in the Explorer ST is designed to balance performance with efficiency and emissions standards. An upgrade typically involves a larger turbocharger with a more aggressive impeller design, or a dual-clutch system for quicker spool-up. The goal is to move beyond the limitations of the factory unit.

- Larger Turbocharger: This is the core component, designed to flow more air. Options can range from a slightly larger "hybrid" turbo to a significantly bigger unit for more extreme performance gains.
- Upgraded Intercooler: As boost pressure increases, the air entering the engine becomes hotter. An upgraded, larger intercooler is crucial for cooling this compressed air before it enters the engine, which makes it denser and thus more powerful.
- High-Flow Exhaust System: A less restrictive exhaust system allows exhaust gases to exit the engine more freely, which helps the turbocharger spool up faster and operate more efficiently. This often includes a larger diameter downpipe.
- Upgraded Fuel Injectors and Fuel Pump: To take advantage of the increased airflow, more fuel is needed. Upgraded injectors and a higher-capacity fuel pump ensure the engine receives the necessary fuel supply.
- Custom ECU Tuning: This is perhaps the most critical supporting modification. A custom tune adjusts the engine's computer (ECU) to optimize fuel delivery, ignition timing, and boost pressure for the new hardware, ensuring safe and efficient operation.
Each of these components plays a vital role in maximizing the effectiveness and safety of a Ford Explorer ST turbo upgrade. Ignoring any one of them can lead to suboptimal performance or potential engine damage.
