Its because of engine precipitation. Becase of the rotary motion of the crank and all of those pullies and everything and the engine sitting sideways, the engine has a natural precipitation, like a gyroscope or airplane engine. This is where the engine will rotate about the z axis when the rotary motion is in the z plane if you have x and y looking down on top of the engine. Its just like that experiment in high school physics where you take a bicycle wheel and put a rope on the end of the handle sticking out on the same axis of the axle and spine the wheel while holding the rope, the wheel will turn around the rope.
I dont remember which is which off the top of my head, and that was for a domestic so it might be different with the possition with our cars, but when you turn left or right, one way will cause your nose to rise and one way will cause it to dive due to the engine precipitation. Hope this helps ya out.
