OM 616 turbo swap

[ponimen]

Hello folks, i am new here,i am from Belgium and i want to converse a 616 to turbo, i already bougt 4 617a turbo piston with rod,oil filter 617a,valves and oil squirls for the bottom cooling. Now i was chearching for an oil pump that delivers enough oil to feed the squirls. The oil pump from a turbo 617 is chain driven and i thingk it wont fit on a drive schaft driven om616.What do you thing about a normal pump from a normal 617,gives it more oil than the one from a 616?Has anyone try this?(put the oil squirls into om 616 bloc)
Greetings and thanks.Herwig.
