G40R - Duratec or 2.0 Zetec

[Ston]

Hi, does anyone know if the G40R's actually had the 2.0 Duratec or the 2.0 Zetec, I've come across some contradictory information, that even the Wikipedia page doesn't help solve. I expect there is a lot of crossover between the Zetec, Duratec and a Mazda derivative engines and was hoping someone could shed some light.

Thanks in advance!
