I bought some piping recently that had a thread welded in. I just bought a brass nipple from Autopro and screwed it in with a few turns of plumbers tape.

i would weld on a threaded fitting, you can buy them off ebay easy enough, just not always the cheapest option.

Stainless threaded fitting for stainless and mild steel pipe.

alloy for alloy pipe

or if its mild steel or stainless you could get the brass fittings brazed onto the pipe.

Lots of options

hey leetom i had the same problem when i got my cooler. what i did was buy a threaded brass nipple. u know the ones with the nipple and the thread on bottom, so it screws in?

i drillled a hole close to the end of the pipe. slotted in the nipple. now to keep it there, i put a nut on the bottom, this is y u put it at the end of the pipe so you can fit a spanner in there to hold on the nut. then you tighten the nut. when you tighten the nut, the pipe should be slightly squashed flat against the nipple, and now it is air tight. i have had it on mine for about 9months with no worries.

I can think of 2 good reasons NOT to use that method.

1. You have created a restriction (however small) in your inlet piping.

2. Imagine if that nut ever came off!!! You could kiss your engine goodbye! I hope you used a nylock nut at least....

dont listen to some of these doom sayers mate. i have used aircraft grade (i swiped from work=oh yea... im an aircraft engineer at aeromil), vibrate resistant nuts for almost 1yr.

it works a treat, as long as you use a nut with the correct NPT you will be sweet.

some guys think up bad situations, they dont offer solutions.

also there is no restriction. compare it to the AFM. :rant: a little 3mm bump is better than a 3cm intrusion into the pipe, which a weld in option would use.

just make sure u tighten that sucker so it is firm, DONT OVER TIGHTEN IT.

now u want to find the nuts with a plastic inner lining around the thread. they will stop it vibrating loose, and lock the bolt in place. it is impossible to come loose. ive boosted to 20psi, and nothing has happened, because i have researched and found this to be the best option. :mellow:

Well it wouldn't secure if you didn't so that's a mute point.

I hope for the best, but plan for the worst.....It's always safest

What are you smoking?....a weld in fitting is flush inside the pipe

now u want to find the nuts with a plastic inner lining around the thread.

They're called Nylock nuts mate.........So are you a qualified aircraft engineer??? I thought they were called aeronautical engineers anyway :mellow:

aeronautical engineers design aircraft :rant:

aircraft engineers work on those aircraft :mellow: , ive been working at aeromil sunshine coast for almost 8yrs, mostly on citations, falcons, and cessna's, but specialize in turbo fan applications.

So you started there when you were 12? Your profile says you are 20 years old, so you must have done a speed degree :rant:....or is that bullshit as well?

man...you guys can bitch. i can feel the estrogen from here

r33cruiser made a valid suggestion, and it seems like it would work fine......IF you wanted the nipple that far up the pipe. i dont, so will probably go for the weld, or tap and cement option. plus i'd be nervous about the nut coming loose, even if i knew it couldnt. lol.

btw, as far as turbulence inside the piping....have u seen the standard nipple inside the pipe? im looking at a stock r34 lower cooler pipe right now. it prodrudes almost an inch inside.

      I don’t really have any ideas how to set the timing on the CAS 😂, sounds like the top, sounds like it maybe misfiring as well as ticking,  got the box sorted 😌, must of been a air bubble on the clutch side

      Use a 2' length of hose (that's 2 foot, not 2 inches) as a stethoscope to localise the source of the ticking. From cam covers? From exhaust or turbo manifold gasket? From injectors? From lower down in the engine? Etc. Use a timing light to set the timing. Put Redline Lightweight Shockproof in the box. It's not the very best thing for the box, but it will take a box that refuses to engage a gear with other oil, and make it engage a gear. I had to put it in when I installed the R33 box I have in my car. It would not select ANY gear when running. Smurf jizz made it work. That was >10 years ago and I still use it. I'm stuck with it now. Failing that - rebuild the box.

      Well done Duncan. The fuel tank bulkhead lid is also in great condition (some of mine were stuffed). These are now out of production and good ones like that are becoming hard to come by.
