To get the the firewall stud u need a small drill that can rotate to work at right angles. Otherwise u can call sum1 out to do it for u, think my mate paid $125 and he had it out in 30secs. Will hav to find his number.

Hmm maybe sum1 on the forum could help out here, i know the beer currency works well! lol

ive taken most of them off, ordered a few new studs, 2.25 each, but the gasket is 130bucks!!

then only problem i have is that the stud closest to the firewall has been snapped (most likely for quite some time now, as ive been experiencing the boost creep and flatspot for quite some time now), i have no idea how im going to get a drill into that to undo it, anyone have any ideas?

Use an air drill, as someone else says, you need a right angle drill, the proper type of air drill will get in there easily. If you don't have air rent a compressor.

i have access to a air compressor and the drill does actually seem to be small enough... where can you get the drill to drill out at right angles? i might just invest in one of them

ill give it a go tomorro night, im still waiting on the studs and the gasket to come in

I use CP air tools (Chicago Pneumatic) and they do a range of miniature right angle drills. I am in England UK, so I have no idea where in Oz you can buy these, sorry.

hahah didnt realise you were form england till just now.. lol

ill have a look around the shops tomorro

i hope i can get the stud out, should i drill a pilot hole out then use an easy out with it? i dont know if the easy out will be enough, it might actually snap before it even moves the stud

ok, ive got pics when the manifold and everything is off, and now the studs have been put in, cost 60 bucks to pull out the broken studs including new studs..

regret going to nissan to order the parts though, for 2 studs, 2 washers and 2 yokes cost 27bucks, too late to cancel so i have them left hanging around for nothing.

will post pics up shortly

after all the trouble, and after breaking another stud(when i was spinning the bolt in with my fingers!!) ive got everything back together, there is no leaks or rough idling anymore.

sorry guys about pics, was in a rush to get everything done

but my boost problem is still there, now its there iff not even worse..

i tried replacing the std actuator with a adjustable N1 actuator, and it seems to have a small flatspot still, but boost still climbs, in fact it creeps from .8 bar to 1 bar still in 2nd gear, and when i change gears, it takes a long time to boost back up again.. i mean wont reach full boost for ages, and not only does it take a long time to reach full boost.... boost now then clims to 1.3bar! and no power at all, till boost drops back off to 1.0bar

its really shitting me, ive tried without any boost controller aswell..

i have a few theories/ ideas

1. when i placed on the actuator with mods, ive had to shorten the actuator arm, so that there was 1mm to pull for the end of the arm to attach to the wastegate (if you guys can understand that, otherwise in other words, for there to be tension to keep the gate closed we had to shorten the actuators arm but the shortest we could go was 1mm shorter than where the actuator was supposed to attach to the gate)

should i fix this? or lengthen the arm a bit further so the gate is slightly open?

2. could it be my CAS retarding timing?

3. could it be my knock sensor being damaged, which ive read to retard timing aswell

4. a stupidly big leak somewhere

5. the manual boost controller? (ive had a electronic one in there... did the same thing.... ive also tried to plum the line straight from the intercooler to the actuator... still did it...

6.something jamming the intake manifold..(dunno why and how but just a though as i remmber leaving a cloth in there and and pulling it back out after the engine was turned on)

it feels like its blowing air an not doing anything about it... ive sent it to two big names in tuning and performance in canberra which i will not name.. spent large amounts of money to try and fix this problem... and it is still not fixed...

can anyone help?? please

PS: with the manual boost controller i think i may be faulty, i screwd it tight, which in turn should just give me stock boost... but it infact doesnt let me boost at all, and at 5000rpm boost starts to climb.. but im going to just plumb it from the pipe to actuator to check it again

ok guys, just tried running the car without the boost controller(just pluming a line from the intercooler pipe to the actuator), power is smooth through most of the rev range, a slight flatspot at 6000rpm.. here is the thing, it starts boosting up till .7bar then creeps rapidly to 1.1bar and looks like it would keep climing if the revs didnt run out.

i guess its not the boost controller issue, and it cant be faulty..

anyone with any ideas?

ok, realised something just before, i boosted it in 5th gear from 80km/h it sits at .6bar at 3000rpm, then when it reaches 4000rpm it starts to climb right to 1 bar before the end of the rev range..

i tried it again but at 70km/h in 5th gear, it sat at .6bar and started to fuel cut!

any one got ideas.. need to sort this out asap

what causes fuel cut

    • 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.
