well since i'm in the process of do a d16a6 N/A rebuild w/PM7 pistons i've been doing some reserch on oil starvation and oil pump up grades. now the reason this has come to mind is, tha we up-grade our fuel pump, injectors, brakes, and whatever we can. shit it's in our gene, we're men. but within all this up grade i rarely here any one up-grading thier oil pump or anything to maintain our motor from oil starvation. so may-be withing doing this thread some question can be answer or even i might even answer my own questions on here thread.
here's flow chart below(thanks downest). now if you see there is a very small qt/[email protected] ratio w/a little porting it should improve the flow rate(for your engine build), with being very careful not to over port.

i'm still a little confuse. it lies within two part on endyn page. the first one is: the opening of the oil holes on the main bearing. if the oil on the bearing is a bit smaller wouldn't opening help with the porting of the oil pump and they open the diameter of the main oil gallery on the side of the block. they also did do considerable radiusing of it's intersect with the oil filter housing. has anyone else has seen and heard anyone else doing this type of work on they N/A build up. Bones you've been around Bisi enough to know if and has he done any type of this work?
and second is really not about the oil pump but more of a footnote question. now on the endyn page they were talking about notching your block. is really important to even notch your block even if you're using your stock rods w/different piston?

now i have readed endyn's link on: D Series Engine Building TipsSome info on swapping around OEM Honda oil pumps:
D16A6 Oil pump flows 46.4 qt/[email protected]
D16Z6 Oil pump flows 47.6 qt/[email protected]
D16Y8 Oil pump flows 35.3 qt/[email protected]
