^^ wow awsome swap to undertake man!!!
I think N54 powered E87 is the best swap around atm. In regards to JBE, the JB(junction box) itself should be fine, I wasnt sure whether the JBE(junction box electronics control unit) would need to be swapped. It would plug into the E87 JB tho if it was required. It was just a thought, Id be interested to know what you did here?
LOL about Key, I must have been having a moment... not sure what i was thinking haha. Just need FOB to match dme/cas, which im sure would come with your engine/half cut/wreck you would buy.
