notthe same engines....the mazda 3 uses a duratec engine and this is a Zetec engine. not even close.

 

I wouldn't say not even close, but I don't think it's worth it to try.

 

they aren't even close. I will say it.

For starters the zetec engines have the intake manifold in the rear of the engine. On the duratec engines it's in the front. If that's not enough of a problem for fitment the chasis are 100% different. Only the newer cross-platformed foci share a SIMILAR not identical chasis.

Secondly, engine management on the mazda platforms have always been SUPER hard to get around. Even assuming you bent the cosmos to your will and got the kit to fit on the duratec engine you'd have no way of controlling fuel or timing like you would with the focus,
