    Turbo oil lines

    I don't know much about turbos but none the less I am throwing one on my 2000 Trans Am. I have no clue as how to run my oil feed and oil return lines. If some one could lend some helpful solutions it would be greatly appreciated.

    Welcome to the site!

    About the only two options to get to the oil galley are the fixture above the filter and the OPSU at the back of the engine. Not sure where they tap in to the system. Easiest return would be to use the hole for the oil level sender on the side of the passenger side of the oil pan. Just guessing at this point...

    Thanks that helps a lot. I was thinking I could put the feed line in the fixture above filter but wasn't sure. And I'll check on the passenger side of pan and see if I can do it the way you say. I appreciate it very much!!!

    If I recall, they make an oil filter mounting piece that is already tapped for lines -- vehicles equipped with factory oil coolers had them.

    Restriction is determined by the manufacturer of the turbo and the center section design (Journal vs Ball Bearing).
    Be sure to check with your turbo manufacturer before deciding whether or not you need one! It is not necessary on all models.

    As for your feed/ return...You are on the right path attempting to pull pressure from the pan area. You can simply drill/tap the adapter above the oil filter to 1/8npt.

    For the return line, try to make the hose as short as possible with as few bends as possible. Remember, it is only gravity returning that oil to the pan! Another great location to return is by simply adding a bung to the front timing cover.

    Most I've seen have tapped into the side of the oil pan. Means needing someone with tig welding aluminum skills. I've also seen a kit that swaps out the piece the oil filter sits on and has outlets. I'll see if I can find it again.

    Cheapest way out on the oil feed side is to simply drill and tap the existing stand, then thread a 1/8npt to -4 AN adapter in. The moroso piece is very nice, but if you can, save the money.
