Either way, I don't think this would be terribly good engineering, anyway. While anything can be turbocharged, the sort of modifications that make a naturally aspirated engine faster don't always make a turbocharged engine faster. Raising compression is counterproductive; exhaust headers aren't compatible with a turbo; changing valve timing may or may not help (or might make things worse), depending on exactly how it was changed. A better way to get power in the 250+ HP range would be with an engine swap, or with a modern turbo setup including an electronic fuel and ignition system, intercooler(s), and larger turbo(s) (compared to the Island) - similar to what the "sport compact" aftermarket tuners do.
