Modular Turbo oil drain kicking my butt I am trying to run the return oil line from my Modular Turbo kit. I have the drain clocked at the 4.5 o'clock position. Looking at the housing drawing a line about 1 inch below center the oil will drain below the bearings. Do yall think it will work? I also have 2 oil restrictor's on the pressure side.

Re-clock your turbo so that your oil feed and drain are vertical.
Turn that 45* fitting so that it is going towards that passenger side.
Let's say that the front of the car in the 12:00 position you may need to turn your 45*
fitting to about the 4 or 5 O-clock position.
Run your drain hose along the front edge of the k-member using adel clamps and screws
to secure it.
Mount your pump on the drivers side frame rail at about the same height
as the turbo.
Run the pump discharge to your oil pan.
Try that and see how it works out for you.

You're going to have to pump the return oil.
Return pumps get a bad rap from all the cheap ones that crap out, get a good gear style scavenge pump and you shouldn't have any issues. I have a single pump drawing the oil from both my turbo's, no issues.

Im running these guys standard pump, like I mentioned above the one pump pulls oil from both turbo's. Some folks have told me its a cheap chinese pump and its going to fail, so I bought a Turbowerx exa pump for backup.... But after about a year and 20k miles the RB racing pump is still working fine.
I had a tough time getting mine to scavenge properly. Originally i ordered the pump and the 3/8th check valve. The 3/8 valve keeps the oil that is pumped, but not yet to the pan, from draining back through the pump and filling the turbos. the 3/8 check valve is vital if your return line is elevated above the pump before returning to the motor you. But in my situation the 3/8th valve only solved half the problem. I had to put a 1/8 npt check valve (1psi cracking pressure) in the oil feed line to keep the oil in the pressure line from draining into the turbo after shut down. After installing the 1/8npt check valves I haven't had any oiling issues.
you can find both check valves I'm referring to on the RB site, but I bought mine cheaper from Mcmaster carr.

from the pics this kit doesnt retain ac right? if so why would it be mounted so low? that turbo is on the smaller size could of been mounted anywhere. pumps are a pain in the *** and always have issues.
