Hey, im in the process of finishing up my list but im getting confused about the oil fittings i need. or have... i already have the return flange, which is a -10 and so is the line and a 1.5" return fitting which is also -10. is there anything else i need for the return line? I dont think there is but im not positive.
Next, oil feed. I have a -4 male and female flange that can bolt to the turbo as well as the turbo is threaded too. Since its an eco, where is the plug i remove to get the oil to the turbo. also what size fitting do i need to screw into the head? Next, what do i need as far as fittings and flanges for that. I figure i can get the restrictor off ATP's site but not positive. and is there any place to get the line? the shortest ATP has is 3 ft and not thinking i need that long of a line...
Cliff notes...
04 Turbo Ecotec, Oil return line: -10an Flange for turbo, 18" -10an SS braided line, 1/2" to -10an, that is what i have... is that all for the return?
Oil Feed: What do i need? i have a -4an male and female flange, getting -4an 3ft ss braided feed line, getting a restrictor. Does this sound right? this is where im confused on what i need.
Also if anyone has a pic of where the plug comes out of the head to tap for oil feed i would appreciate it.
Thanks ahead of time...
Oil fitting that will go into the turbo oil inlet flange ( the one on the turbo lol)

you can pop any one of the ports along the head, or the block to use for your feed supply. if you choose the block it will actually be underneath the manifold/turbo. There is a row of ports that is reight by your balanceshafts. Unscrew one and figure out what size it is or hold off and i will let you know tomorrow. If you choose the head the best spot IMO is right by the EGR bracket area, there are 2-3 ports on that end that you can pop open ( dont know how hard it will be on the car)
For the hose i would ask bonnett, he might be able to get you a smaller line ( you will need probly 2ft one if you go to the egr side of the head or a 1 ft one for under the manifold.
hope this helps a little bit

not ANY ports on the head, 2 are coolant lines. the 2 ABOVE the egr triangle thing are oil, below are coolant passages, I should know.

I used the oil port in front of the engine underneathe the intake manifold....The one next to the timing chain.

I did use that one on my first turbo, that was much higher pressure then on the head

So where would be the best place to pull from for the feed?
Thanks for all the info so far guys. I really appreciate it. im pretty close to having everything. just the oil system has me on the hang up... i appreciate all the info!
side of the head by the egr

awesome thanks for the help!

Actually it's off the side of the filter housing, but that requires drilling and tapping and who really wants to do the work of doing it right.

well what kind of turbo are you running first off? if you are running the gt ball bearing turbo, you want as much oil psi as you can get for the most part....if you are running a standard journal bearing, you want a MAX of 30 psi
So ball bearing turbo you would want the higher pressure port....journal bearing, go with the head (and dont forget your restrictor)
I have funtion7 oil flanges, 10an return and 4an feed with built in restrictor. Then a 12" 10an ss return and 45* fitting to be welded in pan, and 24" 4an ss feed line. I beleive the restrictor in the feed fitting is like 1/16, which is very small but can be drillled out if need be.
I have a 2.4 but Im using the factory oil sensor location in the head for the feed.

Yeah im getting close to have everything finished up with it. like i said. should have the pan welded for me tomorrow. ill have my feed line and restrictor on the way soon.
did that map sensor work for you?

It's the other way around. Ball bearing turbos don't need as much oil since there's less resistance with ball bearings. Journal bearings are basically metal on metal with a thin film of oil between them, that's where you need more oil to keep everything lubricated properly.

450WHP Turbo Ecotec swap in the works...
I used the Autometer brass adapters to adapt the thread size in the head to 1/8'' NPT, and then used 3/16 brake line from there to the turbo, and then another adapter from the 1/8'' NPT to the thread size in the turbo port.
I have never used any sort of restrictor on my oil feed line, as I believe the adapters at the head and turbo, as well as the small size of the 3/16 brake line, provide enough restriction to keep my turbo seals happy. I have almost 10K miles on my turbo setup and no problems so far.
Currently #4 in Ecotec Forced Induction horsepower ratings. 505.8 WHP 414WTQ!!!
Currently 3rd quickest Ecotec on the .org - 10.949 @ 131.50 MPH!!!

Idk about the map sensor yet, Im also still gathering parts but Im close to having everything but I dont see why I should have any problems with the map. The reason I got the map was cause Im getting the sc flash untiI I get hpt, which I also have 310cc injectors from the ld9 sc kit which I should be ok with on 7psi.
Cant wait to see your setup all finished, your car is a beauty

According to APT, and all other information I can find, you want to restrict your oil PRESSURE to the journal bearing, because over 30psi will blow the seals out. MOST of the ball bearing turbos have NON-restricted oil feeds, but DOES depend if it is a small or large frame ball bearing turbo. Contact a reputable turbo seller such as APT, and ask them....They will verify that.
i think im just gonna pull one of the plugs on the head and do that... and get the -4 feed line and restrictor...
How long of a feed line do i need for the eco feed line? i can get 18", 12", 24", 36", 48", and 60" what you guys think? im gonna pull oil from the plug in the back of the head.
lmk as im doing what your doing..lol
