Yeah, easy to get good power from the XE. You can pick a Zetec up cheaper though and no distributor to faf around with!, so it's really down to preference. Fitting them's essentially the same, both require new engine mounts, bellhousing etc, but both are equally well catered for in terms of kit.
With the XE you can use a manta sump etc, but these are getting like hens teeth so prices are climbing.
