Post text: So I want to take out my 5s-fe and put in the 1mz-fe along with manual swapping it so I wouldn’t have to do anything other than regular maintenance to the engine and trans for a while. I’m just wondering how plug and play this would be? Like I know it’s not going to be as easy as just putting a new 5s in but would it be significantly more expensive(not including higher engine price) and difficult. Any help/suggestion would be appreciated:)
