I've noticed that most oil line fittings for turbo applications have 90 degree fittings... Is there any reason for this? Wouldn't straight fittings increase the flow? There has to be some reason, and some of you have to know! haha. I ask because I have lines but no fittings and am debating which to get. Thanks

 

the less extreme bending on the lines the better. plus, you can get shorter lines. you also dont want any wide turns taking up space, because the ss braid will chew through anything it touches.

i really dont know, but those would be my guesses.

 

I was told once that it's good to have the extra length of hose and such, you can hold more oil that way.

 

I have also heard that you want a little slack. But anyone else know about the fitting question? I think im going to use straight ones unless someone has a reason why I shouldnt

 

going to the turbo?

maybe to reduce oil pressure.
But going FROM the turbo you should utilize gravity and use a straight fitting, fitted onto the bottom oft the turbo and running DOWN to the oil pan, no upward bends.

 

Don't worry about it. Brake lines take plenty of 90 degree turns. I think mostly it's just to keep the engine neat so it doesn't run around everywhere.

 

like airborne said..
it's mainly to keep everything "clean" and avoid heat source or moving parts
the longuer the hose.. the more place it has to break, bend,touch moving/hot parts

i try to keep them the shortest i can while still having some slack so it can flex

 

Pat- I was talking about the oil feed, sorry I should have been more clear. Believe me, I know the importance of a clear return path

Airborne- I wasnt worried about having 90 degree turns as much has not having them. I kinda figured what pat mentioned, that the bends may be to reduce the pressure or something. If I have straight fittings it will increase the flow, but is that a good or bad thing?

Denisst- thanks for the input, my lines are like the exact size i need them fing02.gif


But again, Im not concerned with the lines.... its the fittings as the title says. I doubt itd matter either way but I wanted to make sure

 

the bend won't increase or decrease the flow enough to matter. EVERY turbo setup that I've seen in our cars has a bend. It's easier, cleaner, and safer to have the bend. The oil pressure can move the oil line if you get a straight fitting. Get the 90 degree fitting

 

Thank you! that was EXACTLY the reply I was looking for haha
