Stock STi = 225whp on IAG dynojet









GT35R (not HTA86) comparisons/videos below

Dyno graph comparison (stock heads vs. IAG built heads, 272s) to illustrate how much IAG Stage V heads flow; no confounding variables because boost was kept the same as well as the turbo and all other parts of my setup.
