It's actually a pretty good example of how the performance version of the FB20 could be from the original.
Bore and stroke and power are pretty similar between the base Zetec and the FB20.
That being said, the performance version is probably close to the edge. Any more power out of it would likely require massive $$$ or boost.
That is why I'm not too keen on a maxed out 200 hp FB20. There may not be a lot of room for more power at reasonable cost.
Something in the 86mm x 86mm would be much better: 3SG(T)E, K20, SR20 all use it (also 2JZ in L6 form). The square 2.0L 4 seems pretty popular for a performance motor. Less stress on the rods for more rev-friendliness, and a bit more potential valve area for flow.
