There is a small black box with a vacc hose running into it (located in the engine bay, just in front of the driver side of the firewall) - follow this hose and make sure its connected - if there is nothing wrong with your turbo, this will be the problem.

As Stan said, it's the black box by your brake master cylinder, it's called the Pressure Sender Unit. They'll die after a while, but you can usually source them from wreckers pretty cheaply. Simple swap one bolt.

hi all,

thanks all for the replys and help. Yesterday night i took it for a spin to give it another go. after 10 mins of nothing it just decided to wake up. At first the needle was jumping around a bit until it settled down and started measuring properly. Then this morning when I started, it was working fine, then it died again for about 10 mins, then it came back. Fine since.

It seems that it wakes up when i start to hit the turbo. Usually i drive granny style to conserve fuel on the weekdays. like you guys said it could be the pressure sender unit. anything else it could be? also should mention ive only had the car for about 3 weeks, just imported.

About 99% sure it's your sender unit. Exactly the symptoms of a sender unit on it's way out.

yeah just a faulty sender unit.. guage is fine.. and yeah not a priority as it only shows you the boost level.. how much do you look at it? especially if you drive like a granny..

Can i thread Hi-jack alone the line? You know the hose that connects to the pressure thingy, mine keeps cracking and coming off and making a hissing noise in the engine bay (which also causes the turbo gauge to not work, so im still on topic :D) but, i cut the hose at the cracked area and stuck it back in, but the problem is im running out of hose to cut, and i think i need to replace the new hose...has anyone done this? and is it hard?

Piece of piss mate. Just unplug the hose from the sender unit to the plenum... measure it up and buy a new one. Then plug back in. While you're there, try locking it in place with cable ties so it doesn't work loose.

Cheers Howie, always helpful. :D I was just worried coz when i looked at it at night it seemed a bit niggly. lol

I believe from memory it's a special hose - 2mm ID going into the port in the plenum and 4mm at the sender. You'll be hard pressed to find such a hose so you can either 1) find a step-up/down adaptor (plastic one will do) or 2) use a 4mm hose and just wrap a small zip tie around the inlet port to hold it down.

i have this same problem in my basically stock 34, the boost gauge just decides to die and then come back to life a few mins later every once in a while, i started a thread on it also, and i think it might have been howie that said the same thing to me, that it would be the sender unit, im yet to source and install a new one though seeing as it doesn't seem to be causing any problems

yeah, exact same. dies then 5 mins later, strungles and comes back. i'll get to fixing the pressure sender one day i guess. car still flies nicely so im still happy.thanks for all the help all. one last question is what exactly does the boost sender unit look like? i can't seem to locate it. i know i'ts near the brake booster, but still can't find it.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
