Gyre, I thought that too. But what about Mazdaspeed making a Turbo? Doesnt that prove that Mazda does not believe a turbo(with their specifications) will not harm the engine? Could that prevent voiding of the warranty? The question will most likely have some old forum fogie bringing up the sema.org website and talking about "the dealer has to prove..." But wouldn't the dealer have no leg to stand on if Mazda is putting on turbos from the factory? Anyway, I'd love to get one on my car, which is why I'm asking if you'd like one too?
