If I remember correctly, use 2 zx2 intake cams. Believe they are an upgrade on a focus and I'm sure you could find some fairly cheap. Port your TB and Intake mani. SVT header, lightweight flywheel, short shifter, shaved head. Another trick some zx2 guys use, is changing out gears from other models to help with ratio's. However, I'm not sure if the focus can do the same, but it's worth a look. Remember, it's not only the amount of power you make, but how it's used.
