i have banjo fittings with push-loc type ends for the coolant feed/return for my turbo. i have used standard parker push-loc line and it only lasts about 1 month before splitting. it is shielded aswell. im looking for some type of high temp push lock line that i dont have to wonder if it will work of split, it will just work. any suggestions(with part #s if possible!)?

also, the line that keeps spliting is closest to the hotside(of course) and i dont have room for a stainless braided with -an setup. i already tried that. i have a T4 35r with 1.06 housing for ref.

thanks!

 

I'd see what A-spec uses for their lines. The line is nice rubber/silicone type stuff with a decent shielding on it, seems to have worked well for mine thus far and one of my line's loops over top of the currently un-blanketed turbine - although I do have extra shielding on that line.

Or, some of this http://www.atpturbo.com/Merchant2/me..._Code=ATP-OIL1 in the proper diameter. I'm using that on my oil drain line and its been used on a few different turbo's I had on the car. Never had any trouble with it - smells like *** though!

 

I welded 3/8" 304SS tubes to some 14mm banjo fittings, then used silicone hose with normal hose clamps. The tubes get the silicone hose far enough away from the turbine that it stays cool. I have a T4 35R, and before I did this, my silicone heat shielding was starting to turn to sand.

The oil supply is really worse than the coolant lines, since it's closer to the turbine. For that, i used 1/4" 304SS hard line, with silicone fire sleeve to protect it. The line is flared at both ends, with -4 tube nuts to attach.
