Hey guys I'm in the middle of doing my holset single and its time for the oil lines. I honestly don't know anything about this topic so I need a lot of help. Please just treat me like I don't know anything (because I don't) and tell me everything I need, sizes, and also where I can get all this. I'd rather not use any of the stock hard lines at all. Thanks a bunch guys.

 

this is on a 3rd gen

 

stanless steel braided line from summitracing.com or from any speedshop. I would use either -4 AN(I.D. 7/32)
or -6 AN (I.D. 11/32) line, and since AN fittings would be complicated to rig up to the flanges, i'd just use good old fasion hose clamps. Maybe two on each end to ensure no leaks.

 

I also prefer to use good ol' fashioned hose clamps (say that phrase with a hick accent )

Easier to install/remove, cheaper too.

Make sure you use strong ones, not el-cheapos, and also remember hose clamps require repeatative maintenence, meaning they don't stay as tight as always so check up on them every couple months.

 

-10 for the drain line.

 

you can get pre-fabbed 3an feed and 10an drainlines for turbos and its usually cheaper than assembling them yourself.

 

I saw those when I was installing my single from www.atpturbo.com and it seemed that all the preassemble ones were too long. The long -3 would work if you are replacing the entire feed like to the block, but the drain lines were at least 12" long and I didn't use nearly that much.

M-P

 

I replied on the other forum, but will here as well.

You'll need a 14X1.5mm to -4AN adaptor for the block. Then you'll need 18 inches of -4AN braided line. You'll need one 45 degree -4AN swivel hose fitting and one 90 degree fitting of the same for the ends of the line. You'll then need a 1/4NPT to -4AN adaptor for the turbo. The 90 degree fitting will go on the block end of the line, and the 45 on the turbo (You could use both 90's if you want)

Might wanna double check the thread pattern on the turbo as they all might not be the same. The Garrett T series is 1/4npt

I use a -12 as the return because I don't run a restrictor in the line.

 

I think we got that down to a "t"

 

Haha!

 

are you running the return line as braided teflon too?

Or a standard rubber type line?

with the oil temps coming out of the turbo probably near 300+...I wonder whether using a rubber based line is such a good idea(rated right around 300). Teflon is rated for what...400? I honestly can't remember.

I see aeroquip has a new rubber type line that works with standard AN hose fittings thats supposed to be good for 350 and doesn't have the stainless outer braid...

for an oil system...I would never use anything but AN fittings. with oil pressures approaching 100 psi on a cold engine...hose clamps just aint gonna cut it for me.

I run a braided return.. But I also wrapped the top with insulation to keep it from cooking. It should be safe to run a rubber ~300deg line, just shield it with heat wrap or something..

 

You can also get the banjo from ATPturbo.com and replace the entire feed assembly.
