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?

thats not my real age mate, im not debating this mate. the fact is that if he follows my instructions he will be fine.

there is no debate :blush:

You are a wanker.....stop giving bad advice! And stop bullshitting. It serves no purpose and makes you look like a knob!

Mods....apologies for the whoring

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.

sorry munkyboy i have to say this.

BAM,

"IN YOUR f**kING FACE f**kWAD"

RESEARCH guys. :P

end of debate

ps. my bad for the language, but u cant paraphrase a quote :PBJ:

oh by the way... i found a myspace account from your email address..

apparently it belongs to a 20 yr old male, in australia, with no friends.

keep digging that hole champ.

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
