Hello All, I am thinking about buying a civic shell for sale, and then buying basically the engine swap of my choice. However, lots of engines for sale have over 200k++ but are CHEAP. What components on an engine would I need to buy to replace, in order to have a "rebuilt" engine that runs like its "new" and won't give me any issues(hopefully.) I wouldn't want to spent the time/money to swap in something with that many miles, w/o first making it as best as I could prior to hooking it all up. Thanks!
