Blouch 18G-XT 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 TD05H-18G-XT features the Blouch 43 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 430 Engine HP, which means that you can see as much as 330 Wheel HP from your WRX.

Turbine Wheel

The Mitsubishi TD05H turbine wheel is a perfect match allowing for fast turbo response and flowing more than the stock STI or WRX turbo. This turbo utilizes a new genuine Mitsubishi Journal bearing system. These have been proven to work flawless on these turbos, and is the same technology used on your stock STI/ WRX 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.
