Okay,

the 94 Paseo has the 5e-fe
the 93 tercel 3e-e

Im going to guess they aren't direct bolt in interchangable based on them being different engine generations.. is very likely possible with some wiring/ecu change they would work.

Before you spend money on an engine, also get out the jdm 4e-fte swap.. they are pretty inexpensive and a neat turbo swap for either of those cars IIRC.
