How to Choose the Right Turbocharger

Choose a turbocharger by matching the exact vehicle, intended use, available fuel and complete project budget. The right combination includes the turbo, required supporting parts, installation and an appropriate calibration.

EDO Performance and Tomioka Racing share ownership. EDO's parts review starts with your vehicle and goals so that the proposed combination fits the project.

1. Confirm the engine and fitment

Start with the vehicle year, chassis, engine, transmission and existing modifications. A model badge or broad engine-family description may not identify the correct turbocharger. Confirm the exact product application, connections, supplied components and wastegate configuration.

For Subaru applications, read our WRX and STI replacement turbo guide. For an S55-powered BMW, check the TR-TW2008 S55 twin turbo kit application list.

For a BMW N20/N26, the TR-TW2000 pneumatic-wastegate turbo listing explains the PWG fitment requirement. For an S55 project, read our replacement-versus-upgrade and total-cost guide.

2. Define replacement or upgrade

Restoring a vehicle's factory configuration and increasing its performance are different projects. A performance turbo may mount in the factory location while requiring a different calibration and supporting hardware. Confirm the complete requirements before ordering.

3. Match the turbo to how you drive

Discuss daily use, track use, response expectations and the power and torque goals with your installer and tuner. A peak horsepower rating alone does not describe response, the shape of the power curve or whether the setup is appropriate for your vehicle.

When comparing published results, identify the fuel, hardware, calibration, boost, dyno and correction method. Keep manufacturer capability ratings separate from measured engine or wheel output.

4. Review supporting components and vehicle condition

Assess the cause of any existing turbo problem and the condition of the vehicle before installation. Discuss fueling, cooling, intake and exhaust connections, boost control and drivetrain requirements for the intended setup.

Separate required changes from optional upgrades. An advertised turbocharger capability does not establish the operating limits of the engine, clutch or transmission.

5. Plan calibration and testing

Agree on the hardware configuration and fuel with the calibrator before installation. Follow the supplied installation instructions and applicable service information. Arrange the mechanical checks, setup and calibration required before high-load operation.

Fuel economy and power gains depend on the complete vehicle and its use; a turbo upgrade does not establish a universal percentage improvement.

6. Compare the complete project cost

• Exact turbocharger product and included components
• Additional required parts and corrective work
• Installation and applicable calibration or testing
• Shipping, any core arrangements and expected downtime
• Product and workmanship warranty responsibilities

Start with the correct vehicle platform

• First-generation BRZ / FR-S / Toyota 86: review the TR-TS1025-Pan turbo kit and included pre-welded oil pan.
• 2022+ GR86 / BRZ FA24: compare the G670 TR-TS1063 kit and optional oil-pan / EcuTek configuration.
• 2015–2021 WRX FA20DIT: check the GTX29 TR-TS1052 application and installation requirements.
• VW / Audi EA888 Gen 3 MQB: compare IHX475 Turbo Only and Turbo Kit contents against your current hardware and goals.

These are application-specific choices. Ask EDO to review the exact vehicle and intended use before treating any listing as the right combination.
