Blouch turbo upgrades are among the best options for Subaru owners who want more power without abandoning bolt-on fitment. This collection covers the lineup — from the 5056XT turbo upgrade for the 2022+ WRX FA24 to the full Dominator series (1.5XT-R through 5.0XT-R) for 2002-2007 WRX and 2004+ STI. To pick the right Blouch turbo, match it to your target power and how you drive: smaller units spool quicker for street cars, larger Dominators are built for high-horsepower builds.
Blouch's reputation rests on Subaru-specific turbos that install like stock. The Dominator line covers a wide power range, with 8cm² and 10cm² turbine housings to tune spool versus top-end, 3-inch inlets for higher-flow intakes, and ball-bearing XT-R cartridges with billet compressor wheels on many models. Ceramic-coated turbine housings — available on several Dominator and 16G/18G variants — keep under-hood heat down. The collection also carries Blouch oil feed lines for STI 2004-2014 and WRX 2008-2014. When comparing models, watch the housing size, inlet diameter, and bearing type — those three details set most of the driving character. Always confirm your year and model, since inlet fitment and turbo orientation differ across WRX and STI generations.
Brands you'll find alongside Blouch
Blouch specializes in bolt-on turbochargers for turbocharged Subarus, and the range here reflects that focus: Dominator turbos stepped from 1.5XT-R to 5.0XT-R, 16G/18G-style upgrades, and TD05/TD06-based units with billet wheels. The step-by-step sizing makes it easy to match a turbo to your fuel, intercooler, and tuning plans — smaller for quick spool, larger for big power.
COBB is the Subaru tuning world's go-to for engine management, intakes, and exhausts — and any Blouch turbo swap needs the custom tuning COBB's platform is known for. The turbo provides the airflow; the tuning makes it usable.
Beyond the turbo, plan for the usual supporting mods: an upgraded intercooler, higher-flow injectors and fuel pump, and a professional tune. Skipping the tune isn't an option — a bigger turbo on a stock map is a fast way to hurt an engine.

Frequently asked questions
Do I need a tune after installing a Blouch turbo?
Yes — any turbo swap changes airflow enough to require a custom tune. A larger turbo on a stock map risks engine damage, so budget for professional tuning.
What's the difference between the Dominator 1.5XT-R, 3.0XT-R, and 5.0XT-R?
The numbers step up in size and power potential: the 1.5XT-R spools quickly for street use, the 3.0XT-R and 3.5XT-R target higher-horsepower builds, and the 5.0XT-R is aimed at serious high-power applications.
What does 8cm² vs 10cm² mean on a Blouch turbo?
That's the turbine housing size — 10cm² flows more exhaust and supports more top-end power but spools slightly later than the 8cm² housing on the same compressor. Pick based on whether your priority is response or peak power.
Are Blouch turbos direct bolt-on for my WRX or STI?
They're designed as bolt-on replacements for the listed applications, but inlet size, oil feed lines, and supporting mods vary by model — check your year and model on the product page.
