The four things that I know off are:
1: Dashboard sensor
2: Headliner Sensor
3: The climate control unit.
4: Some sort of a computer that is hidden behind the glove box.
I don't know what else is need but I am sure there are a few more items.
Turbos:
I think most people try to swap the engine with a VR4 engine. It is a bitch and from my understanding, it is cheaper to just buy a VR4 because the parts to do a swap are going to be expensive. The other option might be NOS. I am not sure if the SOHC can handle it but you might want to look into that.
Good Luck and welcome to the board
