Hi All, I'm new to this site just hoping to get a bit of advice. I have a Mk 1 2001 Ford Focus 1600 zetec, the engine has gone and I need to replace it. What i'm looking to find out is can a puma 1600 zetec engine be fitted? Is there anything I would need to check or ensure the new engine has before buying it.

Would the engine be a straight swap, Does the ECU have to go with the engine or could the original ECU be used.

Thanks in advance.

Ryan.
