Oil Pump Upgrade, When Is It Needed?

[unique1]

hey guys im wondering what makes the need for an oil pump upgrade neccesary? if i run the motor to the stock rpm limit and make more power does it need to upgraded or only when u raise the rev limiter?

say i wanna make 500rwhp with a stock gtr oil pump with a rev limit of 7000rpm max, is this gonna be fine? i know an oil pump upgrade is reccomended because everyone does it for "safety" but why exactly? surely the difference in a motor making 300hp and 500hp is bugger all if the rpm limit is still the same?

seeing as it is an engine out mod, you would do it when you pop the motor or choose to build the motor.

Luck of the dice really, 7000rpm should be fine with regular servicing and an overfilled sump. Only a matter of time.

hey mate the motor is out and its currently being put together as a cheap drift motor, its just been freshened with rings and bearings and im gonna throw the t04z from my other built motor onto it and run around the 400-450rwhp mark, if it fails i dont care it cost me bugger all (it is a rb30 bottom end and 26 head btw hence the 6800-7000rpm limit).

I just want to know why and when an upgraded pump is needed, not just people saying "upgrade it" because someone told them to do it on there motor.

Id look at using a std rb30 oil pump. With a proper balancer they seem to work quite well.

make sure the GTR pump is in good condition and use a crank collar. if you do this then with a rb30 crank that pump should be fine.

yes...ive seen them running fine in somje drag VL's so you will be fine. They are a gear pump not a g-rotor like the other RB pumps and work really well.

so when you say rb30 pump, is the non turbo one ok or do i need the turbo one? i dont know if they are different so i thought i better ask Ive smashed 2 of them from the last 2 motors trying to get the damn bottom timing belt cog off the crank, what a pain in the arse they are to remove, though luckily i saved one from the 1st rb30 i pulled apart from memory so ill have a look at that.

I still wouldnt mind knowing what it is that actually makes an oil pump upgrade neccessary on any particular motor? is it purely based on rpm?

thanks again for the info everyone
