Pictures of my new to me AC 700 Diesel
Ok, just got it last night. Today, froze my Azz off switching the 30 Mudzillas from my AC 500 to her. Wind blowing, +10F all day. Good news, the 30's fit nicely without a lift! Next good news, she starts great, at least down to 0F, and going from 25" to 30" tires made no difference to acceleration, which is leisurely. The biggest thing that it needs is some sound deadening. After that, a turbo, of course. So far, I like it!

That's the first one I've seen. Diesel makes perfect sense to me in a utility ATV that works more than plays. The Kubota utility vehicles we used at the park where I used to work were diesel and 4wd with a dump box. They were rugged machines.
It ought to be a bit more efficient than a 700 gas machine, and it ought to have more torque.
I remember when dirt bikes went from 2 stroke to 4 stroke engines. The 4 strokes usually required more cc displacement to keep up with the two strokes. We chuckled at the first ones, but they had more torque and more efficiency. Kinda sounds like the same story with the diesel.
Is there a model specific turbo kit for this engine?

It's been cold as hell, but I took it out on the highway to see what she'd do. So no windshield, no hand warmers yet It runs 30 mph/ corrected for the 30" tires should be around 36 mph. Fast enough at 0F to freeze me solid, I didn't really dress warm enough. Thursday I'm taking her in to my mechanic to turn up the fuel and advance the timing. I believe there are higher rpm governor springs available, to go from 3600 rims to 4400. Certainly feels like it comes up onto the governor. Gotta get some black smoke. Absolutely no exhaust smell or smoke, can't have that. I'm getting a 2" lift too. It handles really nice, steers as nice as my AC 400 and I really like the long wheelbase. I have a 2 up seat to put on also. Loud did I say? At Idle, it's ok, but cruising along, loud! Might have to do the turbo just to quiet the beast down. Farm tractor loud, I guess, my dad had a Yanmar tractor that was louder. I'm not worried about speed, talked to a guy in Australia that got 50 mph out of his once turned up.

A turbo is just a turbo without the application engineering. Mounts, inlet and exhaust piping, waste gate (if), head gasket and studs, fuel management, turbo lag and so forth. Maybe there is a kit with all this stuff included that is proven to work.
I enjoy diesel pickups. I know several folks who have purchased tuners and bigger turbos only to blow the head gasket. Once they get the engine sorted, then the transmission lets go. I think diesel performance mods are harder to do than a spark engine. It was easier for me to buy cams, port and polish the head, mill the head, jet the carburetors, reduce the intake and exhaust restrictions. These techniques would take a 120hp Alfa Romeo to 130hp, or so it seemed. It was fun to do.
Anyway, you will have great fun getting more torque out of your single cylinder (assuming) diesel. Remember the two stroke diesels of years and years ago? Maybe an ideal design for an ATV.
Nice to hear you like the longer wheelbase of your 2up Cat. I purchased a 2up machine just for that reason (as well as take the wife now and then.) Heavier, not as maneuverable, but more stable.
