I don't have any specific engines to recommend (I would recommend replacing with same motor year/type). Any time you are installing a different size engine, there will be all kinds of problems. Starting with the motor mounts, exhaust system, Engine Control module, wiring harness, emissions, transmission, etc, etc, etc. This will be an expensive project.
