I'm starting to make my remote oil filter block return. (where the current
filter sits, circled black in attach picture). When the oil comes back from
the cooler, currently the RX8 system only filters half the oil while the
pressure reg dumps the extra back into the pan.

Can I go oil pump -> cooler -> remote filter -> back to block. All the oil
would pass through filter first.

For the oil filter mount, this Earls should do.

That is more of a pressure limiter rather than a regulator.
When the oil is cold pressure can build to over 100 psi.
Normal operation the regulator probably  never opens.

The rotaries don't generate a lot of particles in the
oil. The oil in my RX8 oil stays clean for months.
Particularly if you are not injecting oil from the sump
and mixing 2 stroke oil with the fuel.

In a piston engine the bore gets coated with oil every
intake stroke and then it is burned on every power stroke.
