Holset Cummins HE531Ve VGT turbo servo volts and what size engine can I use it for?
 

Helllo all and greets from Finland.

I have had a big a$$ Holset Cummis HE531Ve (yes, the turbos type numbers are typed correctly) turbo sitting on my garages shelf.

I have it listed on Ebay and loacally here in Finland.

Now it seems I need to source the volts of the servo. With what volts I can run the servo?

The turbo is originally sourced as new unused unit from local Scania spare parts division. So, I presume as the turbo is meant for big trucks, the VGT servo is run with 24 volts. But, as the saying goes "assumption is the mother of all f**k ups", how can I really be sure?

There is no label or anything on top of the servo housing.

Next thing.

As it seems the turbo is not a big sale item on Ebay. What size engine can I use it for?
My current setup is a Ford 2.9 V6 Cologne EFI engine. It is already with a turbo.

I read a bit here and there are quite good instructions to make a servo controller for the VGT.
Can I run the HE531Ve with my V6 2.9 and have it as a daily runner, as it is now with the current turbo?

Thank you for reading.

Cheers
