Hi all,

Tonight adam (chefstagea) and I have got about 90% of his frount mount intercooler installed into his S2 stagea... Just got the last piece of piping to go and we have a slight question about it:

On the stock piping their was a small nipple with a black line going to it... Ive seen some intercooler kits which have these nipples on the new piping. Adams kit doesnt have the nipple on the piping. What does this nipple do? Im thinking ill go get one put into the piping while hes at work tomorrow. Where can I get the nipple installed? (exhaust shop maybe?)

the nipple I'm talking about is the one you can see here on the middle piece of piping:

Cheers,

Chris

On a series 2, you will need 2 nipples. One for boost and the other goes to the power steer pump.

I used a brass screw in nipple found at most auto parts shop. Drill a hole, and screw it in. The alloy pipes are fairly thin so I used some liquid metal approx $8 tube to fillet around the nipple and the pipe to make it stronger.

How to install nipple into a Intercooler pipe:

What you will need:

Brass threaded nipple fitting, with a 1/8 BSP tread on end (Sprint Auto $4.95)

1/8 BSP tap kit (from motortrader $37). This kit is needed as thread on nipple is a gas thread, thus it tapers

White plumbing tape

3mm Drill bit

8mm Drill bit

Heat silicon/sealent

Procedure:

Mark the spot that you would like the nipple with a scratch

Take 2mm drill bit a drill a pilot hole for the 8mm

Drill out hole with 8mm drill bit and more it around a bit to make room for tap

Tap 1/8 BSP thread into pipe

Place 2/3 layers of plumbing tape around the threads on the nipple

Screw nipple into piping and fastern firm but not over tight as intercooler piping is a bit soft could easily pull threads out

Place some heatsilicon/goop around bottom edges of nut on nipple just to ensure the seal is 110%

Happy days!

No finish Installing your frount mount intercooler, with one less thing to worry about :D

One more step, make sure you clean the inside of the pipe very well after to make such there is no metal bites from drilling. don't want them going thru the engine.

No need to buy expensive taps, as the thread is tapered it will cut it own thread, esp in the alloy pipe.

      Duncan's V37.......race car?

      Interesting that it has 2 to the USB stick. Are the ones to the USB stick different? Or labelled anything at all? Telstra 4G is Band 28 is the long range one you want, it's 700mHz. I'm trying to do some reading on the Cel-Fi stuff, but I can't find any decent info online that makes me feel comfortable being able to work out the sort of antennas we could get away to swapping it over to. The antennas I'm starting to do some stuff with at work, are a transparent antenna. They're designed to stick onto the window. Which means you wouldn't even have the antenna outside the car. Volkswagen have just started using the exact same types of antennas on some of their new cars (And from the same antenna manufacturer). But, RF stuff is a bit of a dark art some days, and getting it wrong in your car could make for a terrible waste of money trying to swap antennas :S

      What do you do with all the spares?

      By MBS206 · Posted

      I'm not going to lie Duncan, Saturday and Sunday were pretty rough days. The sort of work I was doing would previously have ended up with me spending about an hour and a half chatting with Neil. Firstly about something I had a question about, and then both of us rambling off on tangents.  I think how Neil did things, and his attitude to getting it done is helping me in part to get this stuff done. Then I can actually do the things I enjoy more easily

      ER, HR bonnet question

      By RBjay34 · Posted

      Talked to another R34 GT-T owner, he said bonnet of his car once fell and slammed from full height because of strong wind at a car show and nothing was damaged or broken, so I guess I'm just overthinking some things but yeah, just making sure I'm not damaging the car anyhow cause wanna keep it for a long time.

      ER, HR bonnet question

      By GTSBoy · Posted

      I would say 100% that it doesn't matter at all. I have an Al bonnet and I drop it sometimes, push it others. Have done so for 25 years and there's no way to tell that either has caused any problems (because there are no problems).

      yeah, a black 4 door HR, stock AT RB20DE. Was a pretty good daily summer car, it was kept in a garage during winter but previous owner was fighting rust so most of the car was covered with rust undercoating, the trunk, floorpan, it started to rust underneath so I thought it would be better to find other chassis that was taken care better and do rust preventions myself, at least I would know where keep my attention at. Plans are simple, enjoy the car as much as I can, mostly on summer of course, winter here is long and not kind to 90s JDM, I wanna keep it mostly stock like, I'm not a huge fan of GT-R look or any body kits so gonna keep it as metal as possible haha, something more balanced look wise and yeah, work on performance, I was thinking about RB25DET but 20DET actually feels fun, as long as it's reliable I think I might keep it.
