I'm not scientifically sure on that......but I do know that most large engines that run 2-stroke have a "full speed" operating rpm of like 950, and idle at like 250-300ish. There's got to be a reason....unless its just because they're so big....perhaps a small engine like a 240 could run faster. No idea. Anyone?

Im simply thinking of it at this point, it may be because of the internal stresses two strokes put on the parts. An extra explosion every stroke really stresses everything. I have an extra engine that i just may give this a try.. The internal cam in the injectionpump will have to be changed, the cams in the head will have to be changed as well.. then a supercharger will have to be modified and put on there. (I think a hybrid, turbo/supercharger would be a good idea, Putting a supercharger that only creates enough psi of boost for the engine to idle, and then a turbo for the rest of the running boost. that way it would be easier to tweak instead of changing pullys)

Go for it! That'd be awesome to come up with a working 2-stroke 616.

Hm... is it possible to change the injectors to DI?.. removing the prechambers and installing larger necks or something..

why reinvent the wheel? Detroit diesels are 2 cycle engines, why don`t you just drop in a 4-53? 4 valve head with a turbo.
might want to beef up the front suspension a little. I think it weight 1100 lbs. plus you would have that cool sound.
