CK27 motor questions

[MESSMAKER]

I have a Bobcat ct225 which is a twin of the Kioti. I have a damaged engine and am looking at a rebuild. I have a few questions. Does it use the same block? Can I overbore to the same size as a 35hp or does it have a different stroke as well? If the answer is yes, what problems if any do you see?
Last question. Is there an aftermarket supplier for re manufactured Daedong motors?
Sorry for all the questions, but I am trying to figure out my options.

One thing I do know that might be important is if your tractor is hydrostatic the 35 hp engine has a higher hydrostat pressure relief setting then the 25 and 30 and it is not adjustable. Not a big deal you would just have more power than pressure I think. It should still be a benefit at the PTO just not to the tires. But if the opportunity arose and you were able to get a new used 35 hp engine and the hydrostat pressure relief was available I would grab that too. It should equal more power to the ground.

Looks like the stroke is the same in the 3A engine family.

Does it use the same block? The question remained unanswered. The difference according to Kioti in the piston diameter is 80 mm versus 87 mm. Does anyone know if the block can be bored out for 87mm pistons?

if possible, then the wall of the cylinders 3a139 is thicker than that of 3a165 - is this an advantage?

Еще заметил, что охлаждающей жидкости в 3а139 значительно больше, чем в 3а165 - это видимо из-за увеличения толщины ткани между цилиндром и антифризным каналом
