oil return w/twins

Postby NYCEGUY01 » Tue Sep 04, 2007 10:29 am

What are you guys allready running twins doing for the 2nd oil return.
Are you just teeing them together. I would like to avoid adding a drain into the pan if at all possible. I dont want to drill into the pan with it still attached and dont want to pull the motor to remove the pan for a proper install.

I think that there's actually a second oil supply port available, right next to the one that feeds the stock turbo.

Ohhh, you're asking about the return...

In that case, I was told this back a couple years ago when I asked the same question, but I've since forgotten.

When I did mine I cleaned the area on the oil pan with a DA and 80 grit about the size of my hand. Then I used a sharp punch (on Air Hammer) to puncture a hole in the pan like a bullet does, it tears the metal and no shaving go into the oil pan at all. Then I keep using a larger object to open the hole to the size I need it, and some help from a sharp chisel.

Then I weld washer on the end of the piece of tube I will be putting into the hole so it is slightly on an angle and there is about 1/2" sticking into the oil pan

then stick it in the hole and weld the outside of the washer to the oil pan.

I caution you make sure that you put the return in between two oil pan bolts so you still can remove the pan, and there is a baffel in there, if mine would have been 1 more pan bolt foward I would have missed it completly

See picture. It is not a good picture but it may help.

I was going to try and avoid the oil pan route if at all possible.
Are there any other good options ??

On a couple of import turbo jobs I did we just took a blunt chisel for the air hammer and ground it to a point then pushed it through the pan. After that I just used a tap and threaded the hole for the correct fitting. I greased the tap up good and caught most if not all the debris. That seemed to work well but I still didnt feel real good about it.

the only other option I can think of is a small oil tank under the turbo and an electric pump pushing oil back into the valve cover

Mine is t-d back into the stock return but my twin setup is unigue and I have my Loe pressure turbo mounted higher and further forward than any other setup I have seen. As long as your turbo drain will gravity feed out into the pan you are fine.

I think Ill probably t it in with the other one first. I have used the small pumps on sleds that I turbo'd and they worked well but its just one more thing to go wrong. lol

If it doesnt work Ill just punch the hole in the pan. I still havent figured out the big turbo placement yet but have been leaning towards leaving the current one as-is and mounting the new one fairly low.
I have lots of room on the chevy. If I go that route the pan will be my only option as it will be too low for the current drain.

Once I actually get in there and start the fab work the room available etc.. will probably make up my mind for me.

Thanks for the replys.

a one inch "T" works just fine for the two turbos - there isnt that big a volume of oil to stack a 1" line full.

Ever start your truck with the turbo oil line off? :shock:
