What gauge are you using to determine these oil pressures, the stock gauge in the dash or an aftermarket gauge?

i am using a prosport digital gauge
Is it an electric or mechanical gauge? If electric you might be having an electrical issue. If your oil pressure truely went to zero you would hear lost of noise coming from the valve cover! However, the normally low idle oil pressure you listed isn't great either....

it is electric and yes 1 or 2 of my lifters are keeping noise so would you suggest to change my oil pump and if so i saw top line have a replacement oil pump selling on ebay is that a good oil pump or is that a waste of time

If your oil pressure were at zero all your lifters would be making noise. That is not to say that a few lifters making noise is a good thing. The problem could be from several issues; needing an oil change, worn engine bearings, or a poor oil pump. I'd check out the system further before changing the pump though.

ok i changed the oil to see if the lifter noise would go away but it didnt i am now about to overhaul the engine because the engine is burning oil i have jus bought the full gasket set but i wanted to know if i can use the same oil pump or if i should change it because the low oil pressure may be because the engine is losing oil internally i havent had to put in oil recently but before i had to keep checking the oil level but since i changed the oil the level havent moved but i am going to go ahead and overhaul the engine do u think i should change the oil pump as well

HELL YES! Change that pump, and your water pump and anything else that is the LIFELINE of your engine. It is foolish to spend all that money on a rebuild and skimp on the most vital components. An oil pump is only $100. A seized engine will cost a whole lot more.

600whp - 600wtq at 30 PSI
Question for you smart guys out there 
Are my rod bearings going or is the oil pump going?
Data;
Cold oil pressure - around 65 psi at 3k rpm
Hot oil pressure - never above 50 psi with a drop to about 40 psi at redline
When hot, the oil pressure drops a small amount (no more than 5psi) with any throttle application. Off throttle it goes back up.
Installed parts;
AWR oil pan
Brand new non ball bearing turbo with the stock Mazdaspeed oil feed line and no restrictor.
Block and pump have around 75k miles.
Thanks!

Seriously what more do you need? Not only has he listed out all the items needed (several times) he's also posted pictures detailing the installation and routing of each part.

I go to my local performance shop and buy bulk hose it's cheaper. I think -10AN is only $1/ft. Then the ends you buy and bolt them on.

pre-made is bad. I agree with MAXX. get some bulk and make your own. that way you will not be limited to how or where you are routing due to length issues. they are very easy to put the ends on yourself and you can color coordinate to your liking. you will be thankful you have extras for all those lines you forgot about.

its the exact same one one i bought. mine spec'd out very good, but i had Tom (MP3 Racer) do the special coating anyway. If you want the proper pressure and longevity for your oil system, I highly recommend having the treatment done. Its worth the wait (approx 3 weeks).

Hard to tell what is exactly the problem. More than likely with 75K miles it is a combination of both the bearings and the oil pump.
With 40 psi at redline, if your bearings aren't worn they soon will be!!
BTW, what weight oil are you using? Is it petroleum based or synthetic? How long has it been since your last oil change??
Pre-made SS hose assemblies are nice because they use the high pressure crimped fittings.and you can bypass the tedious assembly process.
However, the choices for length and fitting end typpes is definitely limited. By going with the bulk hose and re-usable ends you can custom make your lines to your particular installation for length fitting angulation.
A couple of words of advice (unfortunately from experience), be careful with the pre-assembled used ss hoses (NASCAR Surplus) for sale on ebay. Many times these are from motors that have had detrimental endings (NASCAR's version of zoom, zoom, boom boom). They will be left with small metal particles that are embedded on the inside of the hose that are all but impossible to wash out. The particles will eventuall come loose with use. Those particles then enter your engine to cause harm to your bearings, etc.
Secondly, be careful with the "new" colored hoses. They are cheaper and easier to assemble with push-on hose ends. However, they don't stand up to pressure as well as the SS hose. They also do not have very good abrasion resistance which can be a big problem if a hose wears through.
Yeah, it's a decent pump. However, we might be able to rejuvinate your old one with our service.
