What turbo does a 2004 WRX have?

The 2004 Subaru WRX was equipped with a turbocharged engine, which provided a significant boost in power and performance compared to the naturally aspirated engines found in other Subaru models. The specific turbocharger used in the 2004 WRX was a key component that contributed to the car's impressive capabilities.


Turbocharger Specifications


The 2004 Subaru WRX was powered by a 2.0-liter, four-cylinder boxer engine that was turbocharged. The turbocharger used in this model was a Mitsubishi TD04 turbocharger, which was a relatively small and compact unit. The TD04 turbocharger had a maximum boost pressure of 14.5 psi (1.0 bar), which helped the engine produce 227 horsepower and 217 lb-ft of torque.


The turbocharger was responsible for increasing the engine's power output by compressing the air entering the cylinders, allowing more fuel to be injected and resulting in a higher combustion pressure and temperature. This, in turn, led to a significant increase in the engine's power and torque, making the 2004 WRX a highly capable and responsive performance vehicle.p>

Turbocharger Technology


The Mitsubishi TD04 turbocharger used in the 2004 WRX was a relatively simple and reliable design, featuring a single-scroll turbine and a wastegate to control boost pressure. The turbocharger was designed to provide a linear and predictable power delivery, with minimal turbo lag.


The turbocharger was integrated into the engine's exhaust system, with the turbine being driven by the exhaust gases. This allowed the turbocharger to provide a significant boost in power without significantly impacting the engine's fuel efficiency or emissions.


Maintenance and Upgrades



  • Regular maintenance of the turbocharger, including inspecting for wear and tear and ensuring proper lubrication, is essential to maintain the engine's performance and reliability.

  • Many owners of the 2004 WRX choose to upgrade the turbocharger to a larger, more powerful unit, such as the TD05 or TD06 turbochargers, to further increase the car's power and performance.

  • Upgrading the turbocharger often requires additional modifications to the engine, such as upgraded fuel injectors and a high-flow exhaust system, to ensure the engine can handle the increased boost pressure and airflow.


In conclusion, the Mitsubishi TD04 turbocharger was a key component of the 2004 Subaru WRX, providing a significant boost in power and performance that made the car a highly capable and popular performance vehicle. Proper maintenance and potential upgrades to the turbocharger can further enhance the WRX's capabilities.
