2G what size is this -AN radiator line?

[dustyboner]

i'm hoping somebody can tell me the size of the line off the radiator just by looking at a picture.
Its in the way of getting an intake attached to the turbo. So it looks like all i can do is make up another line.

It would have to be a -16 right? Cause the water pipe and radiator are something like 1 1/4" ID.

Its not my car and its on the other side of town so im hoping to avoid an extra trip just to measure it.

Tough to be sure without a measurement, but I'd guess it's -16. If the OD is ~1.150", then it's -16AN, and that looks about right.

Most do 16AN for ease of finding fittings and hose. 20AN is another level of costs and one i did or half did and never again .

20AN OD is coming in at 1 1/4" as you measure but your ID is ment to be OD i assume??? The pictures dont seem like 20AN fittings though as those are a beast of fittings, i got one here so when i find it i can post a pic of the difference but maybe the pic is throwing me off a tad!

20AN is better for oem ID hose size but 16AN is not so hopefully this is 20

I have -20an on mine and it looks similar to that, you can look in my pics to see them.

yeah i know a 16 is way undersized for sure.
i measured a stock water pipe (the one off the water pump) and it was pretty close to 1 1/4 ID. I would assume the radiator inlet/outlet are the same size. It is beaded so maybe i'm off a little and i just used a ruler cause i found that before the calipers.
I found a -16 cap, i don't have any -20 and besides the cap, i only have -12.

Do any of you know how the fittings would be attached to the radiator? There is a weld
here VVVVVV I thought instead of a normal rolled bead, it was a welded bead., or am i wrong?

If the fitting is welded to the radiator, it would be welded at end of the outlet, right?

this is the only other pic i have and it doesn't really show much except how undersized the lower hose is.

I wonder if it would be better to switch to a 2g thermostat housing and water pipe and try to get a normal radiator hose to work.
any suggestions?

motomattx, your setup is killer and all but what really amazes me is how you can have a black car that is so clean. I could take mine to the carwash and it would be dirty by the time i got home.

Here's a pic I stole from @gofer's build thread. Is this what you mean?

yup. thats what i would expect to see if the fitting was welded on.
so am i right in thinking that the weld in this pic isn't to attach the fitting?

I clean it everytime I take it out before I put it away, this includes usually a coat of ceramic followed by a topcoat of wax then wiped down with spray wax to remove the streaks, labor intensive to say the least.

I am thinking that an an nipple was welded on and the hose then attaches to that.
