Blouch TD06H-20GXT Billet 8cm^2 - Fits Subaru WRX 2002-2007 - STI 2004-2017 - Forester XT 2004-2007

The WRX/STi TD06H-20G enhances high boost-pressure performance by substituting the larger TD06H high-flow turbine for the TD05H turbine to reduce exhaust manifold / turbine housing backpressure while still maintaining good throttle response. 

While full ball-bearing performance turbochargers have their place, we realize they are not for everyone - hence the new 20G-XT. These new 20G-XT compressor wheels really are a work of art: stronger yet lighter closed-die forged aluminum alloy combined with state-of-the-art 5-axis CNC-machining allowed Blouch to tweak the aero for even greater mass flow and efficiency from a given geometry. 

And they don't just look good - they really perform: the 20G-XT produces greater peak torque and peak horsepower when compared to the "old" 20G at the same boost pressure! Now that truly is bolt-on performance!
