good effort mate , getting me all keen on doing this to mine now , how did you get on with ur boost issue , ive got the same problem even with the wastegate disconnected it wont go over 12psi , ive got a 2.5inch dump pipe fitted etc , im thinking exsort gasses are opening the wastegate so short of bolting the wastegate closed im at a loss

[Sketchy_Racer]

Have you guys blocked off the pressure relief valve on the inlet manifold? It pops open at around 13psi hence your low pressures maybe?

[u13turbo]

What do you mean by Cargo area stops? I think from what i measure the original mounts are 60mm... You think i should take it back and ask for an exchange on some 60mm stuff?

Personally I would take the tube back and get the 60mm stuff, better safe than sorry. If you look under the rear third of the vehicle above the rear diff and under the cargo area you may have a mount from the chassis to the body that is not quite touching, that's the cargo stop..... I hope you understand my Engrish

Yeah might just do that, Guys at Dotmar seem like real good buggers, Really helpful.

Like Sketchy said it will be due to the relief valve. Simon told me to bash it with a hammer which worked awhile ago, But then I was running standard boost for abit, and now it wont go over 12-13psi without wastegate... not too sure what the problem is.

Get a 1" bung and replace this for the valve. I forget the thread size.
I bashed mine too but it didn't work too well but now with the bung in im happily boosting 17psi.

[richard morley]

ohh yeah sweet is it easy to find ? ill have a look later and if i can find it ill bung it up , what side of inlet manifold is it i.e side , top or bottom , cheers guys

Sounds like a good idea cheers Pete!

Easy as, on top of intake mani, firewall side, looks like a mushroom thingy. Give it a whack and then take it for a spin and you should notice a difference, then get a bung like Pete said to do it properly.

[richard morley]

gave it a bang didnt work so its sitting in my work van , gona get bung tomorrow and fit it up tomorrow night ... should be mean , whats the story with the egr butterfly valve im just bona asshole it and put a bolt through the holes , is that the go

[sibainmud]

That worked for me
See my pic further back in this thread.
Easy as pie.
Not the best but simple. (KISS)
so many posts on this subject
I'll be documenting and posting a complete build now I have a standard turbo 3dr to do
Will post a link when it gets underway this weekend.
Cheers,

[richard morley]

yeah i fucked mine tho managed to put a hole in it , got a bung today though and its all fitted up , see how that goes , so sick of running standard boost

[u13turbo]

Finnally got a new(second hand) starter, After rebuilding mine i found it was still intermittent if it would start or not, Been told it would be a dead spot in the armature.

Found this whole, and am wondering how it would of happened? (sorry its abit hard to see)


Also, just wanting to make sure this intersection connection is allgood? wont be interfering with anything??


One more thing, The vacuum pipe from here is Just blocked off, Whats it for? and where should it go?


Cheers

[sibainmud]

Your tubes are up the shit, you are feeding boost down the vacuum system . Follow each tube from that tee and post where they lead to. I can have a look at mine and tell you or not.
The hole is nothing, if it was a true hole black stuff would be leaking from it
The vaccum switch is connected to the two other swiches that run the fast idle for the A/C and that butterfly shaft that you have removed.

Well one of them goes to the boost gauge, another to a fuel line/injector pump? and another one to some thing behind te battery. I know theyre up the shit not sure what happened.. If you could let me know were they meant to go id appreciate that cheers.

[sibainmud]

The one to the "thingys" needs to be cut and blocked off both ways first. The rest is ok.
Try that. Should go good after that.

Cheers,

[richard morley]

yeah im still not getting anything over 13psi , blocked pressure relief valve , pretty sure its a wastegate issue , anyone got any other ideas ?

Have you disconnected the hose to the waste gate actuator and plugged the hose??

If so its not a waste gate issue.

Have you blanked off the pressure relief valve on the manifold???

If so, then that's not the problem.

Make sure the hose to the boost compensator on top of the injector pump is connected properly.

If all that checks out, and you are 100% sure its all good, then

ITS TIME

Its time to start increasing the fuel.

What will be happening is that there isn't enough fuel being supplied to make anymore boost than 13psi.

So you need to increase the max fuel delivery slightly. Just a tiny bit of a turn at a time, then go for a rip up a long hill with your foot hard up it in 4th gear and see what pressure your getting. Keep increasing it bit by bit untill your getting the pressure you want. Black smoke at full boost is bad. You will end up with engine damage.

I think my LSD is buggered... I recently drained the old oil and chucked in some new Fuch LSD from BnT, But now it just gets one wheel going... today i had to pull the handbrake almost right on to ingage the other wheel, I also recently put new pads for rear brakes and handbrake, including new cables, could it be because the left side handbrake is locked on abit? because it tends to get the right wheel spinning 99% of the time?

You do no that an LSD is not a locker right??

That the break away torque on a LSD is less the fark all???

As in, if you jack one rear wheel off the ground, the break away torque is the amount of force that you have to apply to turn the wheel that's off the ground.

That same torque (the force you applied to turn the wheel that's jacked off the ground) is all that has to be over come before your diff starts behaving like an open diff and just spins one wheel.

So no, your LSD isn't stuffed, its just a normal crappy standard plain ordinary waste of space factory LSD

I love it how people think that somehow a LSD behaves like a locker PMSL

No.... I dont think an Lsd is a locker, Yes i realize they dont lock up, But i also know for a FACT my lsd use to spin 2 wheels almost the whole time, apart from at decent flex. Now, if i try a stand still, on even ground, even friction on each tyre, it will spin the left rear wheel, occasionally it will spin both but not very often.

Trust me, I know there is something wrong, whether the LSD unit is playing up, or whether it is an issue with the brakes.

[mud_slinger]

lsd is prob tired and had its fair share of water in it. weld it

kidding but maybe add some lsd treatment oil you can buy think its redline stuff the lsd clutch plates may be worn and not grabbing or maybe it has been run with non lsd oil and the clutchs are covered in crap

What ever you say dude, what ever you say

I gave you good advice

[Sketchy_Racer]

Pull em apart and chuck an extra shim in the clutch pack, then they start acting more like a locker. I get a good chirp when maneuvering through a car park

Remember LSD is Limited Slip Differential

As in: slip exists and is only limited not eliminated

Yeah i know that, but if you read what i wrote, it has deteriorated extremely since new lsd oil and rear handbrake. it hardly ever spins the left hand wheel, always right, if there wasnt something wrong with it, it should spin the right hand wheel instead of the left at times, Or if it acts like it use too, it would spin both.

I'm running a Toyota LSD up front, and the standard Navara LSD in the back. Yes, LSD's are not lockers, but as you say, you know when they aren't working right. Both of mine have been shimmed due to wear, and i have added an extra spring to my front one, increasing breakaway load. I have found the type/make of oil has a huge affect on how the LSD performs. I am now using Heavy Duty Redline Oil, and swear its better than other LSD oils (the ones I've tried anyway). Well worth the extra cost. BNT have it. You can actually hear the clutches binding/letting go (hard to describe sound) when doing a U-turn.
Knowing how much oil type can affect LSD's, I'm betting thats your problem.
My 10c worth

Ok thanks for that, So it wont be damaging it at all? i can cope with it for awhile aslong as it does bugger my diff..

[kbjj]

Pull out your magnetic bung to check if there is any excessive wear. May give you an early warning if somethings wrong. As long as theres no unusual noises, and you've only given it an oil change (with LSD oil), I can't see how it could be hurting itself.

[u13turbo]

Went out for a play in the snow today, But the alternator has given out.... Lucky to get home, whenever i tried winding my window up or down the gearbox would slip to nuetral, wouldnt get into top gear either... Gonna be another couple of hundy that i dont need to spend at the moment....

[ant-neil]

Have read LSD need regular oil changes
if it isnt as good as it used to be i would do that first
my petrol terrano factory LSD worked heaps better when i did diff oil change and its cheap and easy to do
Might be worth a try

Yeah the problem is that i just changed the LSD oil! like 4,000km's ago.. It was pretty good before i changed it.... Weird..

[churchill]

Pull it apart and take a look at it, you might have a broken spring or worn out clutches.
