240zdan 25 Posted July 17, 2014 Share Posted July 17, 2014 (edited) Just curious, what is your oil pressure at redline? I am seeing 65-70 psi on a hot day using 40 weight oil and am worried its a bit low. Its a stock rb26 however. Edited July 17, 2014 by 240zdan Quote Link to post Share on other sites
fast-datsun 12 Posted May 15, 2015 Share Posted May 15, 2015 The std rule for motors is about 10psi per 1k RPM to 7k would be 70psi. but many factor also come into play and VOLUME is also important. oil pressure at idle comes into play, oil weight and kind of oil. bearing clearances. so there is no one firm answer... 60-70 on a stock motor should be ok, if everything else id good.
