Frount Mount Intercooler Question...

[kidafa]

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

it's for the wastegate actuator/boost controller.

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.

Wow, you guys moved quick on installing this kit to Adam's car!

Take pics and let me know how the end result looks

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

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.
