TNT VB5855 Turbo Upgrade for the 2022+ Subaru WRX: Serious Power Without Sacrifices

The 2022+ Subaru WRX introduced the FA24 engine, giving enthusiasts a stronger and more flexible platform than any previous WRX generation. With more displacement and improved torque characteristics, the FA24 responds exceptionally well to aftermarket upgrades — especially a turbocharger upgrade. For drivers looking to push beyond the limits of the factory turbo, the TNT VB5855 turbo has quickly become a top-tier option.

Designed specifically for the VB-chassis WRX, the TNT VB5855 turbo delivers a balanced combination of power, response, and reliability, making it ideal for both street-driven cars and performance builds.

Why the Stock Turbo Holds the FA24 Back

From the factory, Subaru equips the 22+ WRX with a turbocharger that prioritizes emissions compliance and broad drivability. While this works well for daily use, the stock turbo becomes a restriction as soon as owners add common modifications like an intake, exhaust, or custom tune. It tends to run out of airflow in the upper RPM range, limiting horsepower and increasing heat.

Upgrading the turbo allows the FA24 engine to operate more efficiently, unlocking power that simply isn’t accessible with the factory unit.

What Makes the TNT VB5855 Stand Out

The TNT VB5855 is engineered to match the FA24’s strengths. Its sizing and design allow it to spool efficiently while still providing the airflow needed for strong mid-range and top-end performance.

Key benefits include:

• Improved throttle response and faster spool compared to oversized turbo options

• Significantly higher power potential over stock

• Better thermal efficiency for sustained performance

• High-quality construction suited for aggressive tuning

This makes the VB5855 a smart choice for enthusiasts who want meaningful gains without turning their WRX into a laggy or unreliable project.

Ideal for Street and Performance Builds

One of the biggest advantages of the TNT VB5855 turbo is its versatility. It supports a wide range of builds, from daily drivers with bolt-ons to more advanced setups with upgraded fuel systems and intercooling. The turbo’s power delivery remains smooth and predictable, which is critical for real-world driving.

Rather than chasing peak dyno numbers alone, this turbo focuses on usable performance — the kind you feel every time you accelerate.

A Smart Turbo Upgrade for the Modern WRX

For 2022+ Subaru WRX owners, upgrading the turbo is one of the most effective ways to transform the car. The TNT VB5855 offers a refined solution that complements the FA24 engine instead of overwhelming it.

If you’re searching for a proven, performance-focused turbo upgrade that maintains drivability while delivering serious gains, the TNT VB5855 deserves a spot at the top of your list.
