I'm trying to remember the exact position but isn't that like a 45 degree angle upwards back towards the LIM? Even running a scavenge pump I would think you would have issues. An oil drain facing upwards like that makes no sense to me, I understand why he had to do it, but that's definitely why he had oil leaking back into the turbo.
Why couldn't the CHRA be clocked 180 degrees so the drain was at least angled downward? Was the larger -10 an fitting hitting the manifold?

I think I am the same boat as well... I need to match it up and see how it all fits.

Yeah I tried clocking it a couple of ways, even with the coolant lines disconnected and the drain pointing straight down it still smoked 
I tried working with AMR to get it right, even sent them pics of how the BNR sits but.....................
But it doesn't matter now
Soon enough I will have a new turbo with properly fitted/routed hard lines that has already ready been tested to fit using my Greddy manifold

As precise as the hammer is, I prefer not to use it

Think of it as a sump pump, pulling oil up and out. similar to a sump pump in a basement, or a vacuum on the floor, or heck even the OMP.
The turbine oil seal was not found in fault until we took it apart.
It was an experiment no big deal...

You cannot expect the oil to drain effectively by being sucked up by the vacuum of a pump, especially given its viscosity. Pumps work best when the fluid is already flowing to/through it.

Either way it doesn't matter much, the experiment didn't work out as planned. But he gave it a shot and tried a new approach to the greddy kit.

Just as an aside - I now know of 4-5 different people who have attempted to run a turbo on our cars with a drain pump . All 5 have failed . Hence my remarks earlier in this thread.
Were they all incompetent or is there a problem with doing it this way ?

Yeah the pump was rated for pumping hot oil and worked fine once the engine/oil was warmed up and flowing. Priming it helped a bit but it just wasn't ideal and the oil that leaked into the system when it was cold was then just sent through the charge pipes and made a mess because a bit would leak out of the crappy *** Type R BOV.
But that was that, I tried it, it didn't work. I have even considered putting the turbo on it's own oil circuit with a reservoir and the pump I have but I'm not going to be an idiot and experiment again
K.I.S.S.

otherwise don't be afraid to try stuff, which means falling down sometimes. That's how we all learn and grow.

Yeah I contacted them and I was not prepared for that price tag. Actually they gave me a range and wouldn't really give me any details until I sent them the Greddy. I still think that would be ideal for a low mount setup on the RX-8. From what Comp said and from what I have read on some of the Vette and Mopar forums, the oil less turbos are holding up very well to abuse.

Yeah I believe I used a combination of two different lengthed extensions with two swivels.... basically you just gotta F*** around till you find something that will grip that nut
I remember I tried a very similiar set up with the 3/8" extensions and swivels and it wouldn't bite, but the same set-up with the 1/4" set-up got completely over the nut...... I pondered for days how I was gonna reach that damn nut; the relief felt once that smaller socket extensions worked.... I dont have words haha
