I have a 4020 with M&W turbo on it. Dad bought it new then sold it with 700 hours on to the neighbor in 1972. About 78 the turbo was added. The main reason was better fuel economy. He pulled the same equipment as before. Four bottom plow and 2 row chopper. They set the hp at 105. Tractor has always had great care but in the fall of 89 while driving down the road they had a big bang. It broke the top off a piston somewhere between the rings. Tractor was overhauled and now has 6000 original hours. I also have another 4020 non turbo with a M&W engine kit that has the fuel setup a lot. Never had either on a dyno but the non turbo will run circles around the turbo tractor. Tom
