1. These are Focus Zetec 2000+ spec rods. They are only compatible with a 2.0 ZVH, if you also buy suitable pistons. I've chosen this setup and it fits fine into a 94 2.0 Mondeo block. I'm guessing your looking at Eagle rods - nice bit of kit.

2. Off the shelf: Crower, Esslinger, Zetec Central. I had mine made to my spec from Arias (2.1 - 7.8:1). JE Pistons can also do this work.

3. A Mondeo 2.0l Zetec from Mk1 or Mk2. It doesn't matter which, I expect a shagged Mk1 would be cheapest.

4. Probably - either way this isn't the right base block to use.

Don't buy any pistons until you know the block will be OK at the standard bore!
Dont buy any shells until you know the crankshaft journal sizes!
Weld the CVH head to take the Focus multi-layer gasket.
Buy an EFI injection and start saving for some better management if you want the best results.
Weigh your pistons and rods - match the heaviest to the lightest to get the assembled weights as equal as possible.

Good luck mate!
