- Ok...so which tank should I make? Hit me in the comments!
Tank #1: Aluminum Box, between the turbos
Tank #2: Stainless tubes mounted under turbos
Tank #3: Aluminum Tube Mounted Under Turbos
They will all test my fab skills...but what should I make?

I’m “emptyo” on Pelican. Check out my entire build of “The Grey Ghost” from rusty heap to curvy beast:

This is a Porsche 911 restoration that was abandoned in 1994 after being converted to a race car. My plan is a twin turbo Subaru EZ30 porsche engine swap with 400+ HP to the wheels. Stay tuned.
Do a mix of the two I would run a larger cylinder in the middle giving a cleaner look around the turbos and might give you a little more room than a box
That's a cool thought, thanks!
@@rennch. 👍 the take will have to be large enough to maintain some oil so the pump doesn’t run dry and burn out prematurely, possibly run it to the timing chain cover I’ll look at the one I’m building and see if there is a good spot
Hybrid option - cylindrical tank in the middle. Always love your videos. Favorite channel.
I vote for a single tube based tank in the middle, you can run a drain tube down and through a 90 degree turn in to each end with a pump take at the bottom and vent at the top if you need. You can then put your pump somewhere out of the way at the same level so you have gravity feed. You can run your pump through the ECU to empty the tank on startup.
I agree with other comments, combine the two and do a cylindrical tank in the middle. Cylindrical would blend in better with the exhaust.
The first option like Porsche 935, is my opinion. Good project👍🏻👍🏻
option 2 seems more efficient
Drain lines to a central stainless cylinder aligned fore and aft, the cylinder shaped scavenge pump next to it aligned fore and aft, this mimics the dual exhaust outlets behind it. Bam! Coolness!
Option 3. The turbos do not like any resistance in the flow of oil in the returnline.
I think the box in the middle is the best option and looks like it would have the best clearance specs
Love this project keep up the great content
Thanks! Here's a good visual for Here's a good example of #2 executed well. instagram.com/p/CvaJUNLrhjt/
Yes, like everyone else said mix the two options with the cylindrical tank in the middle.
Option 2 seems more effective as means to having two tanks. You could use a cylinder even there
But can you fit the scavenging pump in behind.
With any of the options however they are all hidden behind the bumper and not seen, so make life easy. And why make the tank out of aluminium?
Use a light steel. It will be easier to build and heat soak more of the hot oil much more efficiently.
Option 2 or 3, leaning towards 2👍🏻

Q- are the turbo oil lines under pressure from the oil pump of the engine.
If so, IMO, a tank is the wrong way to do the return to the engines sump. Definitely no vent as you will spray hot oil on the exhaust casing fire hazard
Positive oil pressure will ensure oil flows to sump as it leaves the turbos body..
option 2. I would recommend Turbowerx scavenge pumps, I use one in my modified 930 and its working great even in hottest middle east summers.
Thank you! Can you link up the one you like the best?
Mate, I would go with the single tank and pump.
But I think it needs to be stainless steel.
It’s vulnerable down there and it would be a bullet proof and simple solution without giving up too much clearance.
Blundstones for the win.
With flex lines not solid, vibration kills SSteel and aluminium.
I was going to say option #1… but clearly no one else is a fan. Maybe, then, the hybrid. Cylinder in the middle.
The square one in the middle 🎉
Tubing would be the better aesthetic but the central design seems like better design.... do central tubing tank
I reckon tank 2, can kinda tuck it up a little to protect it
Really enjoy your vids and look forward to them to drop. Thanks for taking the time to make them. The Builds are coming along nicely. 👍👍
I’d say the box in the center is most pleasing to the eye but I’m hesitant to vote because I gotta be honest I no next to nothing about turbos as everything I’ve ever had has been natural aspirated so I don’t want to steer you wrong.
I think the box is the best option
I'd say option 2
I would say the aluminum tank because you could also add some fins to make it a cooler. Would that help at all? I don't know, I'm not an engineer nor am I building a car right now. I think it would also look better than having two tubes hanging under your turbos.
AL dissipates heat better if that helps. Also I think a solid tube bolted to the turbo will be a failure point due to overall engine vibrations. The longer that drop tube is the more likely it is to be a future problem. I have no idea about turbos but what crosses my mind is to attach SS braided lines to the turbo drains and run them elsewhere to the point of any pump. I heard you say lines running horizontal and forward were not ideal, so if I'm suggesting just that, well, fagetaboutit. The question I have is what are those black lines? Is that something that is deemed to not work or something else altogether?
If the turbo drains are above the oil level in the pan, then just plumb direct to the pan. A separate scavenge system is only needed if the turbo drains are below pan oil level.
I like frankm6601 idea or the aluminum box. keep it simple.
I don't think the drains are sufficiently above the oil level in the pan. Also consider the oil dynamics under acceleration, etc. It seems to me that Michael has determined that the turbo oil must be collected and then gathered at a pump to be force fed back into the engine possibly thru a check valve.
Remember that the turbos are pressure fed oil and drain to a relatively atmospheric pressure oil pan. Since the drains are essentially pressurized out, a little oil sloshing in the pan won’t matter.
I am not sure of the Subaru engine configuration but on my 993 GT2 I gravity fed, with no catch tanks, directly to the lower valve covers. When I went to bigger turbos I used a cam driven, modified VW oil pump. one of my 935s has an ANDIAL engine that has no catch cans and directly feeds to the plate at the bottom of the engine letting the oil pump do the work. Maybe a Tilton electric pump can get the job done.
Bro, can I just hang out in your garage? Sheesh!
Aluminum box has my vote.
stick with it, I love the build and understand the restrictions. I am building a restomod myself a 58 356 Sunroof coupe and prices are "Outrageous" for such a simple car. Budget budget budget because it is rare for anyone to have unlimited funds.
I think you may be able to do a return into the timing cover, but I didn't have the visual angle to determine if that would be viable. What you have to have is the oil not returning higher than the oil level in the engine. You cold pump it there if you want or need the pump; you pick. You'll need a light to monitor to be sure the pump is in service also. Hope this helps you out.
Tank #2
I like the Turbokraft style option the most, and they usually have well developed parts.
option 2 ali box
Tank 2
Hard to say but it looks more professional with the box.
Thanks for the input! Here's a good example of #2 executed well. instagram.com/p/CvaJUNLrhjt/
Aluminium box vote
I grew up in that park. Every day I was there after school and on weekends.
I have no idea what will work better but visually I image the two tanks looking cool.
Here's a good example of #2 executed well. instagram.com/p/CvaJUNLrhjt/
The box looks ugly, however, option one looms to put too much load on the piepe from the turbo resulting in failure, so some flex from the turbos to a tank would be best, option two, how about a tubular tank made from the same tubing as the exhaust.
1 tube
#3
What’s your brake pad challenge? I am back and forth between US and EU if I can help.
On tank I was thinking op1 but mounted under cold side in a fore and aft orientation
Tank2
Stainless cylinders feeding a single pump.
MIKE SAMCRAC HAD A SIMILAR ISSUE ON A CAYMAN AND HAS AVIDEO ON THIS MAYBE REACH OUT?
Do what ever has the least amount of fail points
Central tank seems to have the same issues as gravity draining into the engine oil pan. Separate tanks seems more reasonable, but I wonder how would you mount the passenger side due to the turbo clocking. Will the tank end up in bumper or completely below the engine?
Tank #1: Aluminum Box, between the turbos PS look at that box of $1000 in -AN fittings LOL JK
Box, not two tubes.
We all have day jobs to support our dirty hobbies, and our hobbies are expensive.....blegh. But hey we gotta do what we gotta do.
🇹🇷👍🏻🇧🇪
Option 2
How about running cables from each drain to the sump with inline pump?
