I've just aquired a newly rebuilt ex race fiesta rolling shell with loads of goodies fitted but a big hole where the engine and box should be.

I'm new to fords having been on the french darkside (205s and Clios) for years so i'm not that up on the interchanging bits and bobs within the fords.

What's the quickest and easiest engine I can bang it and thrash the car to death?

I did have the 1.7 puma engine and 'box in mind but looking about no one seems to do that conversion to the mk3 is it a pig to do? you all seem to be going down the 2.0 zetec route but I'm looking for something a lot more 'plug and play' rather than interchanging half the bits off a 1.6 onto the 2.0 etc

Can anyone help

Cheers
Si
