You are going to need just about everything from the zetec powered zx2 to put it into your wagon.,... coolant bottles, wiring, sensors, hoses, computer. etc. A very good mechanic and I just did this swap a few weeks ago. We just parked the wrecked zx2 with a good drivetrain right next to the wagon, pulled the wagon engine/trans, the complete wiring harness, computer, front crossmembers and other subframe parts and nearly everything else and then swapped over the zx2 misc components and finally the engine and trans. While you're in there, install poly bushings for the swaybar front mounts, steering rack and control arms and replace all the ball joints and tie rod ends. You probably want to go over the CV axles too so they are ready for lots more miles. Good Moog stiff plastic sway bar bushings, ball joints and tire rod can be had for under$100.o0 from Rock auto. Add some poly bushings from Energy Suspension or Whileline ( I used Whiteline) for the controls arms for a few bucks more. I used KYB GR-2 struts ( the gas adjusts are no longer available) and progressieve springs to wrap up the suspension and added a 2nd Gen GT swaybar t the rear with new Moog plastic bushings. The car rides very taunt, but not abusive and corners nearly flat. Sits about stock height or maybe a little higher ( I have to deal with snow in my parts)
