like dawgydawg said, the 86-87 2.0 will go in but may need to swap motor mounts. if you can source a mazda bongo engine (12v like the 626 & probe) the intake faces the right direction, & dizzy is on the front of the engine, it would be a drop in, but may require some wiring adjustments, other than that, your choices are endless with time & $$, rx-7 rotary engine, miata engine, kia engine, 626/probe engine are for the most part bolt in, but you'll have some fab & wiring issues, then you have a v6 or v8, which will for the most part require different drive line (tranny, rear axle, & driveshaft) not to mention the fab work & wiring that will be incurred.
