Engine compatibility

  1. Hello, I've been after a cylinder head for my megane 225 for some time now and have seen ones for the Laguna 2.0t for sales but the engine codes are slightly different. The megane one is f4R 774 where as the Laguna is f4r 764, 784 and 786. Does anyone know the difference between them? Would the cylinder head off the Laguna turbo be the same as the megane turbo?

    Any help would be appreciated!

  2. The cylinder heads are matched to the block iirc. Meaning you can't just strap another on. Not sure if they can be machined to match tho, other should be able to confirm.

    Not as simple as just finding another head unfortunately :worried:
     
  3. Ah I see OK that's fair enough thanks for the help!
     
  4. That's not true if cylinder heads same as long as it's skimmed flat then all is good
     
  5. Apologies Jordan, gavrook is correct. It's the top covers that are matched! I'm a dufus :blush:
