will 90* fittings be okay for my turbo setup?

- sc61
- neukin a/c manifold

99 gsr p72 oil pan

IN VTEC

I usually find that the return lines use either:

(1) -10AN straight + (1) -10AN 45 deg fittings

OR

(2) -10AN 45 deg fittings

I prefer the former whenever possible since straight fittings are a helluva lot cheaper than angled fittings of the same size.

what about a 90 degree fitting coming off the bottom of the turbo.

I'm using a -10AN 45* brass fitting off the turbo going to a straight hose fitting.



For the oil pan I used a straight weld on -10AN fitting with a 45* hose fitting.

I have nearly an identical setup (excpet no 45* into pan) and I'm getting considerable smoke after boosting, I'm thinking about getting a 90* off the pan so give the oil a steeper drop in the hopes of aleviating some flow issues..

i useds a 45 at the turbo and a 90 degree at the pan

-10AN line? All downhill? Still smoking? Are you sure it's oil smoke...have you checked your downpipe?

Yeah, try a 45* or maybe 90* fitting. Personally I think it's harder for a fluid to pass through a 90* than a 45* or a straight.

hey dax, im using the hf manifold and the t25 and the turbo sits so low It looks like ill need a 90* fitting to put on the turbo for it even began to start to slope in the right direction. Do you think that would be ok? Im using a restrictor so its not like im letting alot off oil get built up

Well the only catch is, since I don't have the 45* you do at the pan, my line comes in pretty flat, I'm thinking maybe that's causing a backup. It's definatley a turbo related issue though cause when I pulled the vacuum line off the compressor port I had a little stream of oil drip out of the compressor

*hoping seals aren't bad already*

You're not using a restrictor on the oil return right?! Of course not [I hope]...

Do whatever you have to. It is of the utmost importance that your oil return line has a good direct line of flow back to the oil pan or you will experience oil backup and eventually smoke and blow your seals. Oil return from a turbo is completely reliant on gravity feed.

Possibly so. You should probably try to get the 45*. I got all my lines from Stan [Flamenco-T] @ Fast-Turbo. He's the man to contact.

You have the neukin a/c manifold? From the looks of where your turbo is sitting, it looks like you have a log manifold. . .

My neukin manifold sits the bottom of the turbo almost level with the return fitting on my oil pan

have you mistaken someone else's post for mine? i don't think someone else said they had the neukin ac manifold other than me.

The pictures above are of my setup. I'm running a Sidewinder.

i guess im going to run out tommoro and get the 90* fitting to put on my return. i guess it should work. Since i have the restrictor on there the is not going to be much oil getting to it So therefor a large amount of oil will not be trying to drain

SHystrdyGSRtdy

how do you guys know how much oil to restrict with the restrictor?

Curtis2kul

well to tell you the truth, you really dont know how much oil to restrict! alot of people run w/o restrictors with no problems, but once you start messing with used turbo's and stuff the seals get weak, etc. I have one because my return is a little on the sketchy side and i thought it might help the smoking a little(which didnt)
Plus some guys dont want to ruin there brand new turbo by putting to much pressure on it

SHystrdyGSRtdy

werd, reason i'm asking is because i've seen two types of restrictors, one that's a valve you adjust and one where it looks like a fitting with a pinhole in it... i might just go with the pinhole route.. unless someone may think otherwise?

Curtis2kul

i got mine for 12 buck shipped , good quality, and its a ball type restictor. IMO i would use one this style
but its up to you

I know those pics r from your setup, I thought you posted them to show that you had the same manifold (as the orignal poster, aka neukin a/c) and were using those return lines.

I'm just stupid, because I know that you have the sidewinder manifold (I remember your past posts)

I'm feeding with a -3AN Goodridge line with no restrictor. Anything larger and you should probably use a restrictor.

Curtis2kul

well i put the 90 on the return line. Seems to drain a little better but still smoke when im stoped. I guess im just going to have to live with a little smoke for now.

SHystrdyGSRtdy

i think imma go with the pinhole type restrictor (nonadjustable) but i still don't know which fittings i should use for the return st/st, 90/90, 45/45, st/90, st/45, 90/45 ,etc....

anyone consider this for a restrictor?

look at the technical drawing and you will notice its got a little bit of restriction on it.
