I know our cars came with oem dual oil coolers, and there are lots of upgraded larger oil coolers out there but I havent seen discussion about upgrading oem oil pumps (are there even upgraded oil pumps?)

My question is is the oem oil pump enough for say dual 34 row oil coolers with -10 hose?

Im using a 34 row as an extreme example.

I know a couple of people running non Mazda twin oil coolers without any oil pessure problems.
They cool so well that in winter one of them needs to be blocked to help increase the oil temperature.

Yeah a thermostat will be installed as well

Once the system is full with no air, there's really not much more work placed on the oil pump.

And usually aftermarket setups get rid of restrictive banjo bolts and the like. So your oiling systen probably has less work to as far as the pump is concerned.

dual 34 row's is quite extreme. I think you'll be fine however with anything reasonable and good lines.

For reference I run dual aftermarket 19 row oil coolers (which is about the perfect size for the front of a FD) and -10 line and I have not ever had any oil pressure issues. I also run thinner oil than many do here (5w-40 synthetic).
