^^^All your info is pretty much incorrect..

You can just swap the flex plate, if they're both 6 bolt engines.

The NA engine will have higher compression, but other then that it will be fine since it doesnt sound like you plan on modding the car.

Just make sure you connect all the sensors (dont forget the injectors, fpr, knock sensor) just like it's a turbo engine and you'll be good to go.
