I guess it is all about how much money and time do you want to devote to your IT car...
I would imagine with enough money, buying the lightest components...you can make the weight.
It's just a question of whether your willing to spend all of your spare time and thousands of dollars on your car to accomplish this.

I love those cars by the way. Had one with an automatic for a couple of years. Handled great and great torque from the straight six.
