Mega N00b question About OIL Lines
 
the oil feed diagram isnt loading in the stickies

my turbo has 4 holes for oil lines, ive got all the lines and banjo bolts, but im not sure what to do with them now, im used to superchargers where there is only a a feed and return, what are the other 2 for? i guess 2 for compressor housing 2 for exhaust

so how do i fab up running all these, do i weld 2 into one and vice versa or what.

i run the oil lines from the back where the oil filter is (f22), i know i need a t joint. im sure its listed in the stickies, but i scanned over all the oil feed section, and am still a bit stumped.

Im guessing your turbo is water cooled.You dont have 4 oil lines.You have 2 oil lines and 2 water lines.

you don't have to, the water lines keep the center housing cool and prevent coking if you shut your car off after doing a power run. lots of turbos are oil cooled only and last forever. you just need to idle your car for 2-3 min before you shut it off every time you drive it.

entirely up to you.

for the fitting to go into the back of the block you need a 1/8th bspt male to 1/8th npt female adapter.Google it Or just use a 1/8th npt male to 1/8th npt female and hit it with jbweld or lots of teflon paste.The rest should be obvious enough to figure out

you dont drain the oil back to the oil filter..... it gets plumbed to a nipple on the oil pan

top= oil pressure(feed)
bottem= oil drain (gravity, make sure its all down hill)
sides= water (in and out dont matter)

That's really overkill. Just don't do any high boost pulls then shut the car off instantly. I've used the same oil-cooled turbo for the past 3 years and never idle my car any extra time before shutting it off.

water lines are not really needed. i have had a few turbos on my last car taht were water cooled and never used them with no problems. and there is no need to sit in your car for 2-3 minutes before shutting it off. just when you know your getting close to where your headed try not to get into boost too high and you should be good.

so how do i know which ones are my oil and water.

i think im going to run water anyways, just to keep the car safe, shouldn't be too much extra work anyways
