Can you? yes. But it isn't that easy. It requires extensive alterations to accept the Porsche engine/gearbox. Unless you are an expert fabricator, or have tons of extra money, suggest buying a very good Type I engine. If you live in a state that does not restrict engine swaps, you could consider a Suburu engine, or even a rotory, but this again requires extensive work, Plumbing, and installation of a radiator.
