I have a 97 1.6 complete with all obd 2 sensors, wiring, and the even stock tracker airbox (though lately I have been craving the K&N "waaaah" sound....). I did the swap myself. I used an older calmini kit with engine mounts from roadless gear (if I recall correctly).
The electrical is not the problem, as has been said. The intake crossing over the head is what touches the hood. Though it is plastic, and I could make it close, I solved this by cutting out the X of support on the hood which let the hood close nicely.
It was swapping in the larger 1.6's fuel tank(with it's completely different fill hose grrr.) that caused me to decide on a 1" lift kit. (And my steering hasn't been the same since
Had I to do it again and since I ended up with a body lift anyway, I would go for the 2.0. "They" said it could not be done and now I here "they" might have a kit for it. Go figure.
