I agree, find something a little better. Not that theres anything wrong with the hanh 20g turbo kits, let alone the hahn 25g kit rocks, but there are better upgrade turbo options out there to suite your needs imo. But, i made 500+ on my evo9 turbo that i thru in a 20g compressor wheel but i also changed out the stock td05hr turbine for the larger 61mm td06sl2r turbine wheel. I also run on 4bars, e85, and boost 35psi and i have ported everything, ivery supporting mod you can think of, and my turbo setup is more along the lines flowing similar to a hta fpgreen/ef2 from maperformance. About a 54lbs+/minutes turbo. I also have a 38mm external wastegate setup and on a stage3 manifold bored out to fit the larger turbine as well as its porter and polished and on a full 3.5in exhaust system from the 02 housing down. Pretty good turbo setup, but its a completely different setup comparing to your typical hahn 20g kit.
