There are 101 things you can do engine wise. You firstly need to decide if you want to keep the 1.6cvh or whether you want to go for a 1.8zvh or 2.1zvh or Zetec turbo. Go on fiestaturbo.com and there is loads of info on there. If you are going to keep the currewnt engine, i would say get a T3, Begies, FMIC and a 195chip. With that setup you may just nudge the 200bhp mark. Make sure it gets set up by a reputable tuner though.
