my engine is "properly" a duratec... its called a Zetec Rocam, and its 8v cos its a tight squeeze in my engine bay, 2.0 zetec can be done, i just have no idea of prices. Puma 1.7 zetec se lump costs £3000 to be put in, to take me from 109bhp (currently) to 120bhp ish, thats 11bhp for 3 grand. Yes the newer engine will have lots more potential, but ill be skint after the conversion......... hmmmmmmmmmmmm ! ideas
