i am looking for information on how to increase power from the yanmar diesel in the 855d. i know turbo kits are available but the suppliers are not clear on how to increase fueling. i know a pump adjustment or mod is needed. also, i think the engine is under some electronic control. does anyone know of a source of product and information on how to get some real performance for this unit? i know the garden tractor pullers drag serious power from the 3 cyl yanmars but i believe most of these engines have a different fuel pump. anyone?
