You will need some sort of oil returnpump. Do a quick search on "bender" in the turbo section and you find plenty of threads about this problem on their RX-1 kits. I would also make a oil catch tank/-can under the turbo like MCX does with their Nytro,RX-1 and Apex kits. They run one larg hose from the bottom of the catch tank/-can to the returnpump and a small vent hose from the top of the catch ltank/-can to the smallest hoses above the engines oiltank. Their setup work!

The sled ran! Got the turbo hooked up, charge tube all ran everything. Tested it out yesterday and ran for about 40 miles after some fine tuning near the shop. It ran well. Initially I was boosting way more than I wanted, I spiked it once over 8 psi. Scared me... quite a bit haha. In a good way. I opened up the wastegate so I could run last night. Never made more than 4 psi then, which was good in my opinion for the first run. I need to mess with the controller to get me a/f right. Got kind of lean around 3/4 throttle. I have to work out the bugs when I get some time.
The one problem I have though is oil blowing by still. Here is the setup now.
.050 orifice in the banjo bolt going into the turbo, a small oil reservoir underneath the turbo, and an oil scavenger pump (2-3.5 psi is the rating). It was sending quite a bit of oil out the exhaust.
I took the turbo apart today and checked the seals and they all looked good. I had the bolt welded and drilled the orifice to .030 now in hopes of helping this. The oil pump was pulling a decent amount of oil back to the tank too. I have it all set up just as TT says.
On a side note, when taking the turbo apart, I unintelligently was trying to undo the shaft bolt not knowing it was LH threads.... Snapped the god damn shaft in half. That son of a gun was way over torqued from the git go because it took half a turn to break the shaft in half.
So that leads me to my next question, is it going to be cheaper to buy another turbo for $200 and take the loss or is there somewhere I can get an exhaust wheel/shaft for this turbo. It is a TD05H 16G. I saw one on ebay for like $100 but for that I might as well get another turbo.
talk about pissed off.
What are everyone's thoughts?
Boost is addictive. It's all I can think about right now.

Good to hear you got her runing 
Makes sure oil drain from the center section is pointing straight down.
Easy way to check if your return pump sucks enough oil back from the turbo:
1. Install a short hose from your oil tank/catch can under the turbo to a cup/bottle.
2. Fill the cup up with some engine oil
3. Put the hose that goes the oil return put in the cup/bottle.
Fire up the engine and see if oil level increases or decreases in the cup/bottle. Easy way to se if your oil retur system is good enough.
Your turbo is not ballbearing and should not need a restrictor if oil return system is good enough ;-)
Keep up the good work!!!!!

When using an eletric return pump I would wire it so it starts on the first step of the ignition key. That way you can stop your sled - turn the key back to first step for 5-10 seconds - and oil presurre in the turbo feed- and return line is gone. Instead of having oil in the feed line and centersection of the turbo slowly losing in pressure. Oil will find easiest path just like water, and with out suction on the return line turbo seals will give in over time.
Been there done that with the Bender kit ;-)

I was going to wire into the key switch when I get a chance this week. I'm fairly certain by doing that and my orifice and a brand new turbo that I'll be able to take care of the oil bypassing problem.
I appreciate your help on this. Hopefully ill have it running again by saturday. The new turbo will be here by friday if everything goes well. Only a $180 mistake doh.
I'll try and take some pictures tonight of the entire setup.

Looking forward to the pictures. I love it when people do there own work and not just buying a done turbo sled from the dealer -respect!

Do you think it will make a difference or will it return oil easier if I put my return line into the top of the engine on the fill port? I have seen that's where people run their return when not using a pump?

Read this thread about oil return pumps - worth the while it takes ;-)

Interesting read. I still think that with my small orifice and a return pump I shouldn't have any problems. I think that when I had all that oil pressure in the turbo initially it f-ed up the seal somehow. For that small of an orifice i shouldn't have a problem. What I'm going to do when I get everything back together is run the sled for a while to get the oil to temp, then do the pump test. Just to see what is getting moved compared to what is getting pumped.

My oil pump is a piece of #*$&@. I actually got more return oil with out the pump connected than we did while the pump was running. Looks like a better pump is in the fix. Anyone ever use a holly fuel pump blue for an oil pump? They should be a gear pump, I'd think that would work? Or not. I need an oil pump so recommendations would be appreciated now. Other than that, runs like a top but I'm sick of cleaning my charge tube from oil blow by.

I gave you the answer for an eletric scavange pump ;-)
RB Racing Carries an Italian made Specific Oil Scavange pump, it is Pricey but will last a lifetime.
Contact Turbo addiction parts they used to carry them. Ted Jannetty used to be here on the forum he is the owner of the company - great guy to deal with ;-)

Success! Went to the parts store. Picked up a vane pump, 1.5 gallon per minute. Pumps more out then what gets pumped to the turbo. Then I wrapped the turbo and put it all back together, for the 20th time I think lol. Pretty happy right now! Pictures to come by early in the week.
