D series injection pumps

[obthecubguy7]

I have a cub cadet 1572 with a kubota d600 in it. I’ve been wanting to build a mini sled pulling tractor with it and keep the original 3 cylinder kubota that came in it. My question is about the injection pump/injectors. I have been wanting to upgrade that for more fuel delivery and noticed that all of the D series injection pumps look identical (ex. D600, D640, D902 etc) so I’m wondering if those higher output injection pumps and injectors for the larger, higher output 3 cylinder D series will interchange into the D600 to flow more fuel, or if the plungers for those pumps will fit into the d600 pump. Note, this engine will be turbocharged. Thanks
