    It is not impossible, just next to it!! It wont fit the car! Fix the 3.8!..... Replace it with another 3.8 or junk it!

    You can put a jet motor in it if your pockets are real deep! If you change the engine it has to be one that will be legal to drive.... EPA!! Now that 3.8 has all the power you need if it's running right!!
