TBI plenum swap??

I have as some of you know a 2.2 liter TBI motor which has almost no mod parts. Can I swap my TBI plenum for a fuel infected plenum. And if so how much work would there be for this alteration?? I know I would have to have 4 injectors instead of one which I assuume would come with or in the newer plenum also I would have to have a computer to control the injectors which I figure I could snag from a scrapyard. Lastly could this car handle the amount of fuel I would be dumping in it?? With four time the injectors I'd have to regulate the fuel amount. Which I can do but IS IT POSSIBLE. Short of drilling holes in a plenum and installing injectors (which sounds like a fun idea for the derby:popcorn:) and running the wiring any ideas, input, advice, experiences??
