The VNT-20’s larger exhaust side turbine is less restrictive and more efficient than the smaller vnt-15 and vnt-17. This improves the exhaust scavenging, resulting in lower EGT and better fuel economy for the same power output. The VNT-20’s larger shaft thicker, and is a more durable turbo that works better than the more restrictive vnt-15/17 in a high performance application.
This is a special VNT-20 turbo that we modified to allow mounting in the stock A4 location below the exhaust manifold.
Ceramic coating inside and out is available as an option.
