Its just a rocker cover swap.
And no, the RS is still a Zetec as well.
check the "fast ford" st170 modifying guide. "mazda based duratec" "used in the st170, c-max and in turbocharged form in the rs focus"
alloy block, much lighter than zetec (i think 70kg was mentioned somewhere)
see dunnell/minster/raceline/burton websites/catalogues for further information!
