Hi

At the moment I am running an RS1800 head with a XR2i 16V Bottom end in my fiesta. I have just brought a 2.0L Mondeo engine.

What I need to know is which head (RS1800 or 2.0L Mondeo) would be the best to use with the mondeo 2.0L bottom end, i.e. performance wise!

Also which ECU should I use?

Thanks

Dan
