2G Question about priming oil system, and OFH oil feed

[Talyn]

I had the oil pan and pump off for a refresh, and I also am installing a new turbo and switching from on head oil feed, to the filter housing. Unfortunately I forgot to prime the oil system before I installed a new timing belt(And I'm not taking it back off).
That being said, I disconnected the fuel injectors and ignition coil and cranked the engine to prime the oil systems, I left the turbo end of the oil feed line disconnected so that I would know once oil was reaching it, and know that it was primed. I cranked the engine for probably a total of 30-60s so far and still don't have oil coming out of my feed line.

I referenced the article in this link for where to tap into the filter housing for oil feed:
http://www.roadraceengineering.com/instructions/oillineinstall.htm
And it looks like either generation oil filter housing, you just go in the middle on that side, So I removed the plug there and put my oil feed line where they show.

I'm basically wondering why I still don't have oil coming out of the turbo feed, I would think that I've cranked it enough that it should be coming out by now. I did some research, and found a suggestion to remove the brake boost nipple, remove the oil PSU and put the nipple in its place and manually pump oil into the filter housing, I started to do that, but when I started taking off the oil PSU there was already oil there-so I know the system is at least partially primed.

So how much cranking should this take? Or might there be something wrong with oil feed to turbo???
Also, unfortunately my oil pressure gauge is inop, I thought it was just a broken wire, but even after repairing the wire it seems to not be working still.

This is the method I always use to prime my motors: http://www.dsmtuners.com/threads/ho...h-timing-components-already-installed.286487/

You should be able to remove the oil cap visually see oil coming from the lifters under the rocker arms (as shown in the how-to). At that point, you know the motor is mostly primed. From there, I pull the MPI fuse and spark plugs and crank the motor until is primed the rest of the way. If you have oil at the rockers, you should see oil at the turbo feed. If you don't it's either not completely primed or you have a blockage of some sort.

Was trying to avoid that method because I didn't want to make a huge mess and lose perfectly good oil... but wound up doing it anyways, worst part was I had to actually drain some oil from the pan back into the bottle. Then I found out the hard way that the feed to turbo is good, thought I had the end stuck into the VC, but if I did it popped out... Pumped a decent bit of oil onto the VC =/ But at least it's all primed now. Hopefully I'll have this thing back on the road tomorrow.

Do you have a mechanical oil pressure gauge? It takes 2 seconds for oil to shoot out of the turbo oil feed at the housing if the system is working as it should.

No I don't, as for things working as they should, I had the whole oil system apart and completely drained. I didn't have any engine assembly lube unfortunately, I think I put some silicone or something like that on the oil pump gears, and then put a little bit of oil in the housing thinking I could just prime the engine.
Cranking didn't seem to work, but I used the manual pump method and got oil up to the turbo feed, so that should be good I think.
I think the factory oil pressure gauge still isn't working, I am planning to get an aftermarket one soon.
