As mentioned above, lots of issues in migrating an engine from one make to another. Not mentioned are the various brackets, bolts, and hardware which differ.

The only cost-effective way to do this is if you have one car with a dead engine, and a complete donor car with a wrecked or otherwise unuseable body and a good engine. With the donor car, you will then have access to the myriad of minor pieces (many made from unobtanium or verydifficulttofindium) that will be needed.

Figure the time involved to be at least 3 to 4 times that required to build the original engine (or swap in another engine of the same make). Yes, it can be done, if time and cost are not objects.

Whatever you do, good luck, and enjoy the project.
