Could be a small Performance boost with some Adjustable cam Gears

Quote:
the ZX2 was replaced by the Focus ZX3, ZX4 and ZX5. Though the two cars shared the same Zetec engine, there were a few differences. The Focus lacked the exhaust-side VCT, and contained less aggressive camshafts that pushed the power band down a few hundred RPM. They both shared the same block, but due to the different camshafts and the different cylinder head, the torque output for the Focus was bumped up by 8 ftlbf (11 Nm). Thanks to better gearing and less weight the ZX2 continued to outperform the Focus

what are the possible gains from one cam? does it have to be reconditioned in some fashion, or can a good shape cam be dropped in? will a used cam be compatible with the existing valve buckets?

I imagine the gain would be a broader power band. Nothing to make you say OMG I'm sure.
Cams are good as long has they aren't worn down or nicked or damaged in any way.
A used cam can be compatible but you would still need to check the clearances on the buckets with the cam installed to be safe. Unless you want to hear the loudest ticking noise you'll ever hear.

What if we could combine the VCT from a ZX2 with the intake from a SVT?

The intake cam of the SVT has the VCT on it. You can't run VCT on both cams.
