I had a xr5 mondeo, nice car with all the fruit. The mondeo was a big car, you can get a
ecu flash for both the mondeo and focus that will give you 200kw and 400nm at the engine. Won't keep up with a Rex from the line but will beat hem from 60km/hr.
Nice car and the guys on the xr5 forum will also give you a lot of information.
