I have a 2010 E550 two -door coupe base model and I saw a post from a German site about them dropping an E65 engine in it and I'm wondering does anyone know if there would be a lot involved with that engine swap, I'm trying to get an engine that's either supercharged or turbo charged that's not to involved and would give me more then my tuned E550 engine that's at about 475hp I want more but don't want to pay the price of a super car to get it. Any suggestions?
