I have a rear mount turbo fitted to a lotus elise, it sits below the sump so requires an electric pump for its return ( weldon ) I also have a mechanical johnson diff oil pump that I intend to use but this requires the camshafts taken out to adapt for a drive , so it will have to wait for its next rebuild
One thing I will add, is do not go cheap on the pump my return is vented to air so the pump is not sucking the turbo dry and if the pump fails the engine will push the oil out into the catch tank then overflow and starve the engine
i do have fail safes to warn me if the pump stops and a small drain from the catch tank back to the sump
I do not like your drain idea at all , will it work on an incline ie long hill ?
sadly imo a good reliable set up is going to cost money but it might save your engine

Since we're throwing out mostly useless suggestions:
Take another turbo and mount to the exhaust after the first turbo. Pull off the compressor and attach the shaft through some type of coupler to a vw beetle oil pump mounted to an oil reservoir. Run a pressurized oil line to the wastegate can and use a large bleeder style boost controller to control the oil pressure. Use the pressurized oil to feed both turbos. Using thinner oil and a small oil cooler are recommended.
PS good luck keeping this from blowing up within 5 minutes.

The turbo doesn't need a lot of pressure, right? Can you yank the windshield washer system from a random car at a junk yard? Connect the pump to the turbo and route the outlet back to the tank again? How hot can we expect the oil to get? The pump and tank should be able to handle fairly agressive liquids and the oil will have a length of oil hose to cool of in before it comes back to the tank. The system from the right car can hold quite a lot of fluid at least, so you can fill it up as much as needed to stay resonably cool. Or will the oil from the turbo just get too hot?

OK. Madness is burning in the brain of Torkel and a truly crazy idea is born. The turbo doesn't need a lot of pressure, right?

So it wasn't because of the turbo location, but because of bandaids. The only issue with this is the oil supply and reclamation. Everything else should act close enough to the same that it won't matter much.

Why do you think there's not enough slope from above truck to oil pan?
have turbo drain into a small container, from that run a straight iron pipe back to pan...
I dont see the problem.

I have 2 options of turbos and I will let you guys know tomorrow as soon as I know which one I will be using. Lowes has a goodyear rubber hose rated for oil and high temps that is pretty cheap that I could use on both ends of the iron pipe. Now to find a super long supply line.

All of that cost money that I don't have to be able to budget toward this. Even though I have almost all my budget left after selling all the parts I needed off the car, I still want to be able to do this for under $150.
