I had recently wrecked my 350z and I have an engine with 50k miles and a manual transmission. The damage is to bad to repair and would cost a lot. So I started searching for a 350z with a blown motor or just a shell. I found one which is my exact same year(2004) but only thing is that it’s an automatic transmission. My question is if I can just simply swap my engine and trans into the new body without any problems? Would I have to drill anything, swap my ECU and wire harness, any type of fabrications? I don’t have the money to buy a newer car as I’m fresh out of high school.
