So I'm a complete newbie when it comes to engine swaps, but I plan on putting an LS3 in my 89 240sx. I am in no rush to start the project or get it done quickly as I know it is not a cheap swap. I want to gather whatever parts I need little by little over time before I finally buy the engine and transmission. I would just like to know if anyone has any recommendations on what I can and should start buying now so I can have everything I need to start the project. My main objective is to spread the costs out over time because I don't want to drop $15K-$20K all at once
