For a turbo engine the biggest issue is the exhaust side and that is the same same with both the 530 and 531 with almost identical flow.
The site you linked to is nice to read but a lot of the info is out dated and coming from the US. You need to look to Sweden for good information

Thanks for the info Dai, I happily stand corrected.
I will have a look in to Erland Cox.
