Boost Lab

The best Boost Lab turbochargers for the WRX are the two in this collection: the TD06SL2-54X Turbocharger for the 15-21 WRX, part BL-0654-8FA20, and the BL54XR Turbocharger for the 22-26 WRX, part FA24-54XR. Choose by generation first: the TD06SL2-54X is the 2015-2021 car’s option here, and the BL54XR is the one listed for the 2022-2026 car.

A turbocharger upgrade replaces the factory turbo with a unit intended to move more air through the engine, which is why it sits near the top of most WRX build plans. It is not standalone, though: a larger turbo affects boost control, fueling, intercooling, and tuning, so owners usually plan supporting parts and a professional tune around it. Start by matching the turbo to your exact generation, because the two products here are generation-specific and do not interchange. Check your year and model before ordering, and consider the cooling side of the build in Performance Intercoolers alongside this collection.

Boost Lab is represented here by a focused, two-turbo catalog, one unit for each of the two recent WRX generations. That focus is useful for shoppers: instead of a long universal list, the TD06SL2-54X and the BL54XR are each named for a specific WRX application and carry their own part numbers, BL-0654-8FA20 and FA24-54XR. Through these products, Boost Lab is a specialist option for owners going beyond the factory turbo.

Four related turbo and forced-induction brands help frame the alternatives. Blouch Turbos is known for turbochargers aimed at Subaru applications. Garrett is a long-established turbocharger name whose range spans motorsport and street performance. Tomei is known for Japanese engine and forced-induction components developed around platforms like the WRX. HKS is one of the best-known Japanese performance brands, covering turbo and engine programs alongside its wider catalog. Before deciding, read our guide to turbocharger upgrades for the 2022 WRX.

Which Boost Lab turbo fits my WRX?

The TD06SL2-54X, part BL-0654-8FA20, is listed for the 15-21 WRX, while the BL54XR, part FA24-54XR, is listed for the 22-26 WRX. The two generations use different applications, so match the part number to your car’s year before ordering.

Do I need a tune with a Boost Lab turbocharger?

Plan on professional tuning as part of the project. A turbocharger change alters how the engine makes boost, so the tune and supporting setup should be arranged with your tuner for your specific car rather than assumed from the turbo listing alone.

What supporting parts should I consider with a turbo upgrade?

Intercooling, fueling, exhaust flow, and boost control are the usual areas owners review with their tuner when moving beyond the factory turbo. The exact list depends on your generation and goals, so treat the turbo as the center of a planned package, not the whole package.

Is a turbocharger upgrade a beginner installation?

No. Turbo replacement is involved engine work with oil, coolant, and exhaust connections, followed by tuning. Most owners use an experienced shop or tuner for installation and setup, even when the turbo itself is listed for their exact WRX generation.
