Besides, there would still be the electronics issue to contend with. It's the electronics that shut down the boost when the IC pumps stop working (or become erratic). I'd bet you'd spend more time trying to make the ECU work correctly with an air-to-air set-up than any part of the conversion.

For what it's worth, there are enough tested mods covered in the various threads that cut down on heat soak and don't trigger any electronics issues: increasing the coolant capacity, modifying the plumbing to truly isolate the IC water lines from the engine coolant system, bigger heat exchangers, upgraded IC water pump, and auxiliary cooling fans. I guess it's cool to be the first with any mod, but unless you're so ambitious as to attempt a turbo conversion I don't know what the point would be to attempt an air-to-air IC set-up.
