Modern TDIs are marvels considering they are hauling around cars weighing almost 3k pounds. The 1981 Golf weighs in under 1900 pounds. Getting to 70 MPG will be the easy part. The hard part will be the 7 second 0-60 to happen. High torque FWD cars are a handful and it will be difficult to get enough tire under the car to handle both high torque and LRR.
