Is it possible to swap my engine?
Is it possible to switch out my Nissan engine with
another Nissan engine?
of course, for cost and ease, find the same size and model engine that is in there and replace. If you are asking about installing another size engine, you will need to research which engine will fit and bolt up to the existing frame, and what custom work would be required. Cost is also a determination. Frequent some Pathfinder forums to check some articles and or even post this same question.
