Ok serious question:

I'm ordering water lines and oil drain line, and have NO idea about -AN sizing. I've done some searching on this in the past, but can't seem to find the thread anymore.

For my water lines, I need 5/16" which is 8mm, which is -8AN right?
For my oil return line, I need 5/8, which is 16mm, which is -16AN?

Is this right or am I way off here?
Trying to order stainless braided lines asap.

Found this chart on siliconeintakes which kinda contradicts my logic:

AN is pretty easy.

whatever the number is divide by 16 and that's your OD. welcome to not being a n00b.


that chart is BS. this wouldn't be a problem if people stopped using the same assindine measuement system ever developed in the history of anything.

Ok, so for my:

Water lines which are 5/16, I need -6AN
Oil return which is 5/8, I need -10AN

Correcto?

This is the standard size most people use, yes.


Though when I was talking to a turbo rebuilder when I was working on a customers car, the builder suggested that for garrett turbos that the ID of the oil drain in the smallest part (usually the elbow) should be a minimum of 1/2" ID.

Most -10an fittings are less than 1/2" ID FWIW... he said go to -12an fitting and never every worry about the drain. Finding a -12an fitting can prove to be difficult though.

I see.
Well I don't need a fitting, I have two barbs pointing at each other, so the -10AN would be a completely straight short tube, and more than enough flow to not be a restriction.

True for steel (not flex) tubing.

Flex comes in various ID for the same -AN. The Earl's Speed-Flex Teflon / SST braid is 0.56" inside diameter (the hose, not the fittings).

So are my sizes still off then?

Here is where I'm thinking of ordering from:

Braided Stainless Steel Lines

My water lines are sourced from the regular locations 1 on the mixing manifold 1 on the front water neck. Pretty sure they are both 5/16" OD fittings (so my ID on the hose needs to be somewhere around that size)

My oil return is 2 5/8" barbs (so my ID on the hose needs to be somewhere around that size).

I've always gone with 6an if it's flexible hose for turbo water lines. Are you running stainless flex braided for return too?

Summit racing has a hose calculator thing for ordering AN when you have regular hose diameter numbers... It's been a while though.

Are you looking for a braided hose? I went with silicone (5/8 size with barbs like yours) and it's been holding up great so far. No leaks, still soft and plyable, etc.

Well if the price is almost the same, why not?
I'll check out summit racing, thanks.

Yeah I considered this too, but it seems like the price is almost the same. We'll see

That's friggin' hilarious. I just got 3' of that blue LOL hose in the mail from ATP yesterday and didn't even notice.

You also want this

To go with your LOL hose

Except that stupid drain nipple thing no longer has the o-ring groove, so you have to order the gasket or just RTV it

I know it sounds wack, but I've even had luck with that universal braided hose kit for an s13/4. Kinugawa has a decent one. I've done that on a nx2000 I built with a t28 so figured I'd try it on the miata and a 2560. Figured since it was a Garrett it would work and it did. Came with all the paper/metal gaskets as well. I've always just rocked silicone for the oil drain, if I did rubber I just make sure to use a paper drain gasket and a longer metal tube from the turbo to dissipate some of the exhaust heat. AN drain is kinda baller though.

I believe this is for hard lines. The wall thickness seems way too thin for a hose/braided.

I already have the oil pan welded with a fitting and a brand new turbo fitting from kinugawa so that's all done. Just need the actual hoses for water lines and oil drain.

So -6AN for water and -10AN for oil return it is then.

Ordering

Vlad, i think you should return your Begi manifold and get the tacotaco manifold.
