A little history for those that are new to the early and current john deere 1600. The first two or three years wam that deere made had power problem. In 2000 or 2001 deere company had a solution which to turn up the injecter pump which took it from 51hp to about i guess 55 hp. Model year 2002 deere put a total different engine with turbo on it. It was 1600 turbo. i have just a regular 1600 non-turbo and i want put turbo off a little VW, honda, or ford car. I know you just don't throw a turbo on something and call good. There is math formulas for sizing turbo. any ideas ????????
