some weeks ago the bottom end of my wee fezz decided to start chapping on the door at me. was wondering f i could get a bottom end for it from a 1.8 or 2.0 focus. alot of you rs turbo boys use the zetec bottoms on the 1.6 head. can this be done with the fiesta mk5 zetec-s engine. ? any help will be appreciated.
