How Have You Done Your Turbo Oil Return Lines On A Rb26/30?

[BoostdR]

I have my motor running but the turbo's are leaking oil. looks like my return lines are to small. How did you guys do yours? I used a Tee into the std block inlet. Is this enough flow?

mine is the same setup as yours - im also running a t piece back to the block but im thinking that the I.D. of my hoses might be larger than yours?

my lines are not braided, im using orange earls hose (i just remember the size of the hose)?

if your turbos are seeping it sounds liek your engine is breathing heavy, when i lost compression on my rb26 the turbos started seeping oil (i dont mean to freak u out)

What is the ID of the hose, they look tiny, on a 35 i run a -12 drain....

not sure what size you need but those do look very small looks like a -3 or -4 from the photo, also where the t is the oil might pool there from the front turbo because it has to go up for a bit at the t, id be running -12 like gtr1993 said, the feed hose is under pressue and the return hose is suppose to be just gravity and no pressure so the return needs to be considerably bigger than the feed

They are JIC -10. Speedflow -10 is JIC -14

I upgraded to 19mm ID hose when a heat sheath shield into a Y pipe. Smoke is all gone.

yea, the oil drain needs to be nice and large, 19mm / 3/4" is the same size as factory on the GTS-T (i assume the GTR ran a similar size as its all gravity return)

I have currently running in my rb26/30 and it's all good with no leaks.

I bought special hi-temp oil hose from Enzed, which is resistant to hi temp oil on the ID, and wrapped it in heat wrap so it didn't perish from the outside.

I tee'd into the block using a brass tee piece with sealant on the threads (ie going into the block)

For the oil feeds and water returns I went on ebay and bought a braided line kit for my turbos (guy's name is eiji takada, all oil and water lines landed in Aus for around $158, fitted perfect, best value purchase of my whole conversion). Details in this thread:
