they renamed the 1.3 rocam as the series name and duratec as the public name, and yes they come on the mk6 why i have no idea.

and yes your right the 1.6 in the street/sports are rocams, again why they didnt use the zetec 1.6 engine is beyound me, the 8v makes it drink more petrol which imo was noticable, i did hear the zetec se 1,6 fouled on the bulk head
