The N/A QD32 is a rock solid engine it's the TD27's big brother without all the overheating taken care of should run damm near forever. 2T oil, oil catch can good filters will go a long way on these.
The other thing is parts QD32 shares like 80% of stuff with the TD27 so parts are easy to get, ZD30 good luck with that it's going to be expensive.
