again ..these are manuals/guides.. for OE spec motor/oil.

use a different oil (not OEM honda oils), install a aftermarket cams, start porting the head, change pistons to a higher/lower CR, change your oil pump to a high flowing type then do an oil pressure reading ..i bet it aint OEM spec anymore

i dont doubt what the manufacturer/honda made their engines to have at OEM spec but once u start modifying then it will change. just like any other cars.

thats what im trying to say ...
