So is this a straight line car with that turbo? I bet the displacement of your turbo is more than your engine...lol. That thing is bigger than my... well it's big! What sort of power is to be expected from that setup?
4" exhaust on a rotary sounds really deep and burley. I had a 3.5" and I liked the tone a lot, it was just a little loud for an everday car (which your car definitely isn't
)
