Answer 2

It is completely legal to do engine swaps in the U.S. but you must update the engine tag on the car so as not to have someone else work on the car and then put the wrong parts on the engine. You can do this by getting a data information plate from the dealer and stamping the new info on it then replacing the new plate with the old if it is a different size/style engine. If its the same size/style engine then you can leave the data alone. Also ensure that the emissions are compatible.

Good luck and hope this helps
