I thought as much, but odds are someone out there has done this. Usually there's at least one odd ball on these forums who's done the ridiculous; who's said damn the feasibility. There's a guy on my 350z forum who did a V8 swap at a cost of close to $20,000, even though any kid who's gone turbo for $3-$7K will blow the doors off his Z in a straight line and around a turn. He completely messed up his weight distribution also, but that didn't stop him.
