thanks for reply!

yes there is a restriction on turbine, but we will se if that is enough, so my oil pressure dont drop too much.

On EU models, only om617 have oil cooler, 615 and 616 doesn't have it.
I will have to see will it work without it.

i will install oil temp gauge and watch for temperature, for mineral oil I will try not to pass 240F.

Thanks, any suggestions are welcome!
