flexpipe and y2k intake manifold, 2 parts that work and supplement parts u already have (intake and race header)...then port ur TB. u'll still b 50-75bux under ur max, take that and save it 2wards a rainy day/next mod.
wontu - Is your 2000 focus one of the early ones with the old style intake manifold. The early 2000 foci had a big stinkin' resonator that sat on top of the valve cover between the filter box and the TB. If yours is like this then you already have the old ( better ) intake mani. If not, get one. Adds hp and tq. Not huge, but worth the $$$ you'd spend.
