I bought a 800.00 yanmar tractor awhile back and its just a spare tractor. I was kinda thinking it might be fun to make it a tractor pull tractor. I got the tractor running good and got everything fixed on it and not it just sits there since I have a big new holland 4wd tractor. I have a turbo off of my sand rail from when I rebuilt the motor and went to a bigger turbo. This turbo is a off of a audi car capable of 25psi of boost which I think would be more then enough for this motor. I was wondering if there was any mods you can do to the fuel pump on these things to get alittle more fuel out of them. Or if anyone knows someone I can send the injectors and injection pump to get them hopped up. The tractor is a ym3110. Any help would be much appreciated. thanks!
