The 1.6 ecoboost is a turbocharged sigma engine, it's essentially a modern version of the 1.6/ 1.7 engines fitted in the puma.Must admit I haven't heard anything bad about the 1.6, but most people in the motor trade don't rate the Ecoboost engine.
Which is why it's an ideal choice for a conversion.
The 1.6 ecoboost shares absolutely nothing with the 1.0 or 2.0 ecoboost,all totally different engines.
