Boost Lab TD06SL2-54X Turbocharger for 2015+ Subaru WRX FA20

Part Details:

The Boost Lab TD06SL2-54X Turbocharger for the 2015+ Subaru WRX FA20DIT platform is engineered to support high-horsepower builds targeting 500+ horsepower with proper supporting modifications and tuning. Designed for both aggressive street use and track applications, this turbo delivers strong top-end airflow while maintaining responsive spool characteristics for usable midrange performance.

At its core is Boost Lab’s exclusive 11-blade 54X billet compressor wheel featuring extended exducer technology. With a 54mm inducer and 71.4mm exducer, this design improves airflow efficiency and high-RPM performance. Paired with a TD06SL2 turbine wheel and 10.5cm² turbine housing, the combination provides substantial power capability suited for built FA20 engines and advanced turbo setups.

Fitment

Designed specifically for 2015+ Subaru WRX models equipped with the FA20DIT engine. Fitment should be verified for custom exhaust manifolds or rotated turbo configurations.

Supporting Modifications

A turbocharger of this capacity requires substantial supporting upgrades, including high-capacity fuel system components, upgraded intercooling, appropriate boost control hardware, and professional ECU calibration. Drivetrain reinforcement such as clutch upgrades may also be necessary to handle increased torque output.

Frequently Asked Questions

Is tuning required?
Yes. Professional ECU calibration is mandatory to safely operate this turbocharger and achieve its intended performance potential.

Is this suitable for a stock engine?
While installation on a stock engine is possible, built engine components are recommended for sustained high-horsepower use at this power level.

How does the 10.5cm² housing affect performance?
The larger housing supports increased top-end airflow and higher peak power, though spool characteristics may be slightly later compared to smaller housing options.

Recommended Supporting Forced Induction Components

• Intercooler Kits – help control intake temperatures and reduce heat soak at higher boost levels.
• Boost Controllers – improve boost targeting accuracy and consistency when upgrading turbochargers.
• Wastegates – regulate boost pressure and support stable turbo system operation under load.
• Turbo Inlets – support improved airflow to the turbocharger and reduce intake-side restriction.
• Turbo Bypass Valves – help manage excess boost pressure and maintain smooth drivability during throttle changes.
• Fuel Delivery Upgrades – commonly required to support higher airflow and maintain safe air-fuel ratios.
• EFI Tuning – tuning is required to calibrate boost control, fueling, and ignition after a turbo upgrade.
• Clutch Kits – increased torque often requires upgraded clutch capacity to prevent slip.
