I have a 4120 and would like to boost the horse power up to near what the 4720 is. Has anyone else did this? If so, what was the cost and what did you do? Thanks
You can uprate the engine by using the non "E" parts from a pre 2009 4720, the intercooler, turbo and injectors. Or probably ever higher hp rated parts from the non "E" 318 skid steer parts list. This will not be cheep though.
