I am curruntly in Spain, but I am in the military, so I am here temporarily. I am hoping to take the R4 back to the U.S. with me. The engine still runs fairly well, it has had a lack of oil changes, that is for sure. I want to clean it up and try and get it to run better than 80kph. If I am able to take it back to the states, I will most likely do a complete restoration of the car. Thank you for the information on the engine.
