I got the turbo off of the engine today from the wrecking yard. On the air box it did say "Ford", not "ATS". It also had "Turbo Diesel" on each fender above and rear of the wheel well like Fords did in that year. I would bet that it is surely a factory turbo motor. The only number I could find near the water temp sensing unit was - 0216W. Hope that helps. It's at Stayton Auto Wreckers about 12 miles east of Salem OR. Ph # 503-769-3525 or 800-699-6682. Owner's name is Dennis. Good people to deal with. He even pulled the motor for me to make it easy for me to get the turbo off. Real good people. Good luck.. P.S. Rod made a hole in the oil pan.... Al
