Semi S55 oil pump upgrade

this may be dumb question but...

New to N55 and currently in the process of rebuilding one due to spun bearings.

If possible to bolt up is there any benefit to installing just the primary S55 oil pump in place of the std N55 pump? From what I have read it flows more and has a bigger bearing.

Yes and here is a link to a kit on Turner, you might be able to take the part numbers and buy the parts cheaper somewhere else
