Been doing some part searches etc and it seems that the only difference in the engines between a 5103,5203,5303 and maybe 5403 seems to be the injector pump and maybe the turbo. Has anyone attempted to increase their tractor power by changing out the injector pump? It seems on the surface that it would be a lot cheaper to change pumps than buying a new tractor. Not say that I'm going to do it but was looking for thoughts. BTW; from JD's parts website a new injector pump with core is about $800.
