lmao, cmon man, you're way too paranoid. The engines are EXACT. Seriously, you're stressing too much, your car will be better than ever. Trust Nissan, even if they were different engines,(WHICH THEY AREN'T) the cost difference would be so insignificant that Nissan wouldn't care about pulling a fast one on you. The real issue that you 99% won't have to worry about it just making sure that they are giving you a new engine instead of rebuilding your old one. Simmer down, bro
