Hi I am a noob here. I have swapped several Mazda 6 2.3 engines with Ford Fusion Blocks making necessary Timing adjustments. I have just bought a 2010 Mazda 5 with an engine knock. Can I use a Ford Fusion or Millan 2.3 for this 5. Is it still the same Block with the same Cam shafts ? any help would be greatly appreciated...... I did some research and found some info that a 07-09 Fusion engine can be modified to fit a 06-09 Mazda5, Can someone tell me if a 2009 Mazda5 and a 2nd gen. 2010 Mazda5 have the same engine?
