EFI upper/lower intakes, fuel rails, injectors, new fuel lines, new fuel pump, air cleaner and tube. I am sure there is much more I just cant think of them right now.
you'll need an EFI fuel pump. easiest way to use it is to get an 87+ tank (86 would probably work also, im just not sure if they are the exact same as the aero cars)
No. The fuel pump on your car is on the front driver's side of the block next to the power steering pump. If you switch to EFI, you'll have to buy a fuel pump block off plate to fill the hole.
