Rb26 Braided Turbo Lines

[endless]

Going to get some braided lines made up as a few of mine are corroded and leaking..

Having removed the turbos last night i have a question in regards to the lengths. The water (return i think?) from the split on the block for the rear turbo does a loop before the banjo joint on the turbo and the oil supply for the front turbo does the same.

I assume this is so the pipes are equal lengths due to the different locations the splits are on the block. So on to my question..

Should i get the braided lines made up to the exact same lengths as the standard piping (including the loops) or can i get them made up shorter - not sure if this will effect supply/return to the turbos and possibly cause premature wear?

Anyone who could shed some light would be helpful

Hey,

I think those loops are to allow movement as the manifolds expand/contract (the pipes are quite stiff).

I replaced mine with braided lines (no looping) when I went to a big single; no problems thus far.

Not sure if a single would be same in this case... what i am thinking is the oil or water may take the path of least resistance giving one turbo more / less.

I'd urge you to use stock replacment steel lines, not braided. Especially if it's a street car. The braided hose will perish relativly quickly witht he constant heat cycling.

But hey, braided hoses look pretty I guess...

Oil cooler kits all use braided lines, never thought a braided hose would perish any quicker?

I am more wanting to do this for ease of installation - obviously looks aren't important as you can't see down there once the piping is on!

well...... oil cooler lines dont run near the exhaust manifold, turbo lines do

just use that orange stuff with the fibreglass inside it, works wonders for high temp sheilding

they come in different sizes to suit braided turbo lines, breather hosing, wiring looms etc

ive used that stuff on breather hoses that are actually touching exhaust piping, its been about a year and its no where close to burning through

edit: sorry i just realised your still running your twin setup and i also urge you to run the standard metal lines for more reasons than 1

just make sure you use fresh copper washers, the lines have no kinks or have ever been bent

what i wrote above applys to topmounts but i guess you could put some sheilding on the steel lines too? haha

As was said above, oil cooler lines are not exposed to the same heat/thermal cycling as lines in/on/around exhaust manifolds, dump pipes, exhaust housings etc.

How often do are you planning to remove/install the turbo's???

Measuring and making the hoses will take you hours to do properly... Not to mention the cost.

Also, that orange sheithing is designed as a flame barrier... it's designed to stop a direct flame from penitrating it for a pre-determined amount of time. It dose work to insulate against some heat though.

Hmm good point.. I do have fresh gaskets/washers for all the lines, might be hard to find piping that hasn't been bent before though as it seems you need to bend it around a bit to remove the bastards.

I used the orange stuff to shield a teflon braided oil feed that ran very close to the exhaust manifold (<5mm clearance) and on the turbo drain covering blue rubber hose. After less than 1000k's I've pulled it all apart and the shielding on the drain looks fine however the hose underneath is charred while the orange stuff has dried out and crumbled on the oil feed with the teflon line also blackened. Don't assume this stuff does anything! Hardline and a good air gap are the way to go.

New lines form nissan arent all that expensive, and will definately outlast anything you can make in braided.
