While the indirect injection engines do seem to be more tolerant of vo/wvo, it may also be a combination of several factors. The i/d engines tend to be older designs and therefore are possibly built stronger and heavier, especially the i/p. As engine development has "progressed", engines of all types have been built closer to the event horizon of distruction. While this is good for production costs, power to weight and fuel economy, they don't tolerate changes to the fuel type they are designed for. I think an older i/d engine with turbo will work fine on wvo/vo, it may in fact be better, due to turbulents in the combustion chamber mixing the fuel n air better. I note engines designed to run on vo have different injector spray pattern and injector opening pressure to give a wider more atomized fuel spray. This is all theory, I have no practical experience of this.
