Hi, I'm new here. I might be buying the new Fiesta, The 1.4 Zetec or Zetec S, I was wondering whether you could tune the engines very well or not, What can you do to it either of them? What power gains are there to either? Could you fit a turbo to them? Thanks, Any Info will help, Matt

 

Not really, the 1.6 you can get a reasonable gain from but it's not cheap to get there, they come alive with cams, Look at Shawspeed for information.

The Zetec-S can be upgraded to 144bhp, by mountune performance, and it'll keep all ford warrenty's etc. It's not that cheap, but its bloody impressive what they can do!
