I'm guessing that Porsche are going from its famous boxer 6 engine to a larger displacement boxer 8 engine. Think about the 997 MkII - it wasn't just a facelift. A practically all new engine, new transmission, wait, forget that, it was pretty much new everything. By now the engines are very heavily tuned, and it's going to be hard to get the NA engines any faster. The solution - move to a larger displacement. Simples! It's exactly what TVR did.
