Hey...I have a nice little 87 xr3i but the engine refuses to run properly. I wanna make it reliable but not destroy it so im thinking of upgrading to a zetec. I have two donor cars available, a 97 escort 1.6 zetec or an 03 mondeo 2.0 zetec. Which of the two cars will be simplest/best to use and what is involved in the conversion? My car is an early MFI so I know i will need to use all the bits assoc

iated with the EFI but what else?
