Its a big job to do for just the oil pump.
Here's some things to do instead
-Always start the car and drive straight away(no sitting idle)
-Never use more than 25% throttle until the oil temp guage has moved above 70degrees
-Always use slow shifts until the oil has warmed up
-Dont use cheap shitty oil
-Always allow for cooldown time
Easy
If you plan on taking it on the track, overfill the sump to the bottom of the hump on the dipstick, and try not to use r compound tyres (they generate lots of grip which moves the oil in the sump)
If you blow the motor up for whatever reason, THEN you do the jun oil pump
