Blouch 20G-XT-R Turbo

Take it to the next level with a 400-440hp capable turbo

Direct Bolt On

This Blouch turbo will bolt directly in place on your WRX/ STI. It comes with all the necessary hardware, coolant lines, drain tube, and gaskets to make this a complete bolt on package. No modifications are needed to install this turbo but an ECU recalibration will be necessary after installation, see your tuner for more details.

Compressor Wheel

The Blouch 20G XT-R features the Blouch 47 lb/min fully machined billet XT compressor utilizing new age aerodynamics. This allows for more flow from the same given size compressor wheel. This turbo has the potential to flow as much as 470 Engine HP, which means that you can see as much as 380 Wheel HP from your WRX/STI.

Turbine Wheel

This turbo uses a genuine Garrett GT3071 (56.5mm) turbine wheel is a perfect match allowing for decent turbo response and flowing more than the 18G turbo. This larger turbine wheel reduces back pressure to the engine making more power. The 20G-XT-R uses a Garrett Ball Bearing Center section that reduces friction, increases turbo response all while being more durable than a typical journal bearing turbo.

Turbine Housing Options

Choose between two different sized turbine housings to taylor your boost response and power. 8cm2 (8 centimeters squared) is a great option for those wanting a faster spooling turbo, and are willing to sacrifice some top end power. The 10cm2 housing is best for those looking for the most power possible and are willing to sacrifice some low end power.

Wastegate Actuator

Comes standard with 15psi wategate actuator preloaded to 18psi. Optional boost pressures are available. See a sales representative for more details.

Off Road Use Only

This product is legal in California only for racing vehicles which may never be used upon a highway. Check your local and federal laws prior to installation.
