Turbo Oil Drain Fittings

[Hanaldo]

Hey guys,

Sorry if this has been asked before, I did a search but couldn't find anything specific.

I am getting a bit wear of the ol' cut n clamp rubber hose job that I did to get my oil drain to fit when I installed my Hypergear G3, and I want to make up a braided line to replace it. However I'm not sure what fittings I need. Does anyone know they type of fitting and thread size that I will need for both the turbo end and the block end? I'll be using Speedflow gear if anyone can even give me a specific part number?

Also, what size hose should I use? The oil drain is gravity fed if I'm not mistaken, so I imagine hose size is important. Is AN -4 the correct size??

Thanks all,

Martin.

much bigger dude, -4 is usually used for fuel, you need more like -12, need as little back pressure as possible.

try couplers malaga for yo fittin.

Yeh I meant -8, no idea why I said -4 So -12 should do it??

I can get the fittings from Go Gear, I just don't know what I actually need. I'm going to need the actual drain itself, the part that needs the gasket? The stock one is a push on fitting, I obviously need a threaded fitting. Should look something like this:

But I don't know what it's called?? Also the fitting that screws into the block, I don't know the thread size??

Ok, after further research, I THINK I'm after part number 463-02 from the Speedflow catalog. But they appear to only come in one size, does that mean these fittings are a fairly universal part among all turbos??

i used this

http://www.ebay.com.au/itm/Turbo-Oil-Return-Line-Kit-Nissan-Skyline-RB20DET-RB25DET-w-Garrett-T3-T4-/290727032084?pt=AU_Car_Parts_Accessories&hash=item43b0ae7514

^( my kit was was stated as a 20cm so just double check measurements etc, not too sure what they mean by the 15cm then 20 in the item list )

with a 10AN Male Flare to 3/4" NPT Male Fitting for the block ( ebay too)

and lastly the braided line was just abit short so i went to the plumbing section of bunnings and got a male to female coupler/ joiner which may have been a 15mm or 20mm fitting and screwed it in on the drain flange adapter or just the other adapter below it. so just bring in the pipe to see what fits

sealed up all the threads with a oil sealant with no leaks to date
