would anyone suggest even trying to put a turbo on an 1989 2.0 lxi FI

sure, why not. Just do a DIY setup and you'll have one sweet sleeper!

You may want to rebuild the motor if it's on the higher mileage side. And you'll want to go synthetic with the oil. But if your compression is decent and the motor doesn't eat up oil, go for it!

you bet you should
