Default Oil Pump Mods - Max Effort

I'm experimenting with oil pump mods in order to increase flow volume and efficiency at lower rpm's and also add reliability...

So, I'm in the middle of building a solid turbo street engine, a 93' B230FT(squirter) with Wiseco Pistons, RSi rods, ect. Also I'll be running a remote oil filter and cooler.
This engine will be built for lower-RPM power and reliability so I'm motivated to improve the oiling system, mainly the stock oil pump since there is no "performance" pump available.

It seems most people get by just fine with an OEM or stock style oil pump as long as the oil transfer tube o-rings are installed correctly and in good shape..
So why would I bother modding a perfectly stock oil pump?

4 things:
-Can't leave well enough alone.
-Fixing things that aren't broke
-OCD
-Reckless Curiosity

This is my first Volvo engine so please offer some constructive criticism if available.
