This might change your mind. It shows that SOHC EJ25 big plenum manifolds flow more CFM than the sti manifold. Also has less runner to runner flow variation. Longer runners generally makes for more low end torque which is good for turbo engines because the turbo picks up the slack later on and carries it through the rev range. Shorter runners are better for NA higher rev engines.
