V6 = Duratec
I4 = Zetec
You have the Zetec engine in your car. That is how it is commonly referred to here. Check the Zetec forums for lots of info about mods, maintenance, specs and other memebers rides. The Zetec engine has actually been around since the mid 80's if I remember correctly and has quite a history over in europe.
Specs for the year you have are something like;
130 HP
135 TQ
Because you have the later car(98+)it is equipped with VCT which is Variable Cam Timing and is located on the exhaust cam only.
And yes, this is a great engine. Very reliable and has very few problems from factory.
BTW, Welcome to the CEG, Enjoy your stay
