I’m doing a stock rebuild for my SR20 and wanted to ask a question about the flow rate of the s13 oil pump. I’ve heard it’s the worst flowing pump across the different variants 13/14/15. I didn’t feel the need to go gtir pump for a simple engine rebuild but it is going into a drift car so will be under stress. I’m wondering whether I’ve made a stupid decision potentially.

Is there a way to improve the oil flow?
