Ordering an Engine.

I am oredering a rebuilt engine with a 3 year 30k warranty. I have a choice of a 2.0 or a 2.2. I know I aint gonna be fast with either one. I just know I could go about 300-400 cheaper to get the 2.0. What years can I get one from? Is the 86 2.0 the oldest I can get or what? I know someone can answer this for me, so Please do so. I am ordering befor Wednesday. I am leaving early thrusday morning for Texas for Heat Wave, so I need to know by Wednesday, but as soon as I know I can order, so if anyone knows like now would be great.
