The price will depend on mileage, considering any other damage, and so on. Also, different buyers will ask for a different price. However, with the mentioned mileage, one may find any engine between $2500.

For the replacement of an old engine, they cannot go for the original dealer of Nissan. They will have to find any local or trustworthy workshop. The workshop will charge more for the job than the new one because they will need to work on the old engine before attaching it to the car.
