I was looking at a 5.3l aluminum 350 h.p. from turnkeyenginesupply.com. I imagine it would be hard to fit in. I have a 2.7l in my 2001 boxster right now, does anyone know how this might swap? Medium difficulty? Extreme difficulty? I know that I would have to get a new tranny to one that can handle the torque of that 5.3l beast, what could I keep on the boxster with this new engine?
