Rb20/rb25Used On 25/30. Differences?

[sriver killer]

Hey guys,

I've done a good solid search on the forums and I am trying to find out the differences, if any between factory oem rb20 oil pump and rb25 oem oil pump

Originally was intending to use a genuine nissan oem rb30et oil pump but instead I was sent an rb20 oil pump.

There isn't a problem using the rb25 oil pump with the rb25/30 tho I haven't found anything direct about the rb20 oil pump.

The oil pump that I recieved is 15010-79S06

The rb25 oil pump is 15010-5L800

If found that the there isn't much difference should there be a problem with using 1.5mm restrictors front and rear?

Any input would be much appreciated
