Zetec 2.0ltr V's i4 (rs2000 engine)

[stevefield]

A mate of mine is building a kit car,thing is he has a 16 valve 2ltr engine out of an RS 2000 that he would like to use, but wants to know if the 2.0 Zetec is a much better engine. Does any body know the difference in weight beetween the two lumps?,and what is the tunning potential of the engine he has.

Cheers

Steve
