Outer Limits 4x4 Board

gudday...I used a GT3071R in my build...great setup still running strong with 30 plus psi, if interested check my past threads for full build details.

good luck

gudday,

TD42T with a few goodies, 30 + psi, built engine 5 years ago, tows a 3 ton boat, gets driven hard, still going strong on Fuchs XTM15w40, blew a head gasket and over heated badly - when head was pulled I expected to see uglyness but this oil held together. there's probably better out there ...

yep X 2.....i couldn't figure it out either!

been here before...real PITA, solution is to either force fluid into slave (oil can and silicon hose) and back bleed up to bleeder and master. if that dosent work I have then taken nozzel off bleed pipe and cap off master, then with a squirty bottle forced a large volume of fluid back through to the ...

im very interested to see where this goes..........keep us posted.

You could also fit a Dawse Valve in the system to regulate boost?

Nope. it'll only increase boost.........i fitted a external waste gate as it suited my application and dumped unwanted charge air quickly, it also gives you the ability to play around with the gates opening pressure easily by ...

Garth, are you not happy with your motor build?

not by any means.......been running it hard for 3-4 years now, had boost set at 30psi for a long time but with the towing it wasnt going to last forever (boats 3.5 ton) so wasn't too surprised when a leak appeared.
Still hits 27psi regularly and is ...

gudday tye...been awhile i know, rig still going strong besides a head gasket last year from too much advance/boost. Still hunting down a quality LMM dmax drive train without paying 16kUS! might have one outa texas ATM.
All good your end mate?

checkout the TB48 custom inlets....can be found by 'googleing' the image....they are pretty trick!

yep ..never use "copper never seize" it makes it worse.......use the graphite based stuff

yep done both sides now, towing 3.5 ton boat out of boat ramp and was too lazy to get out and flick over hubs for turn around at top of ramp.... that killed one.
replaced with quality jap ones.....can dig out make if req

was thinkin the same....though if he made the inlet manifold he could sell a sh*t load! ....looks functional.

was his old setup a 2876 with the 4" housing or a machined out disco 3" housing over the 76mm wheel? just wondering cos the latter is what i have and it goes pretty hard. maybe im upgrading to the gtx if its a big step up again? ;)

The 2876 was just the std disco housing.
There is alot to be had ...

Hi Ben,
Yep the .74mm I have came from The pump and injector builder so it'll be right. As for the advance I got the call today about where it needs to be so it's all good now!!!
As for the engine; it's finished being built so just got to fit the bolt on's to it,fit the engine and wait for the ...

off memory gq standard timing is .74mm but as said can change heaps with modded pumps especially when chasing power. better to ring and check.
how is the engine going anyway dave. coming along alright??

gudday

(if the petty clutch is set up the same as the diesel) i had same issue, it was air, as the engine heated up the air expanded pushing in the clutch.....they are a prick to bleed with the clutch line loop running up the fire wall creating a natural air trap.

The best way I found was to ...

gudday dave

I guess you can play around with it at a later date to see what works for you.
When I first did a tune for max power we set it up with as much as 6' advance which was great for EGT's and the huge PWR ali radiator looked after the heat no probs but ended up doing a head gasket after 12 ...

Gudday, these were the instructions given to me a while back when i built my engine.....

1. Place the engine on TDC by aligning the pointer with the mark on the front pulley.

2. Remove the 12mm hex plug from the back of the fuel pump.

3. Install the dial gauge and fitting and preload the gauge ...

got same prob in one of my GQ;s with an manual trans. I played around for ages trying to get it to work in the end gave up and had to send the whole cluster in to get repaired - cost a fortune to fix but was a common problem I was told.
My GQ ute with an auto trans also has a non working tacho, I ...

ha ..no worries, just thought I'd better get on to it with all the disasters happening here!

how much advance? is 6' too much? I think standard is 3' but 6 lowered my egts and gave a good burn.

na never did....if you get em will still be keen. great for a under floor water tank when camping

I have a Gt3071R setup on my truck with all the gear to go with it, they are not suited to everyone's taste but suit my application for open road use.
I run mine a little rich to help a quicker spool but still only makes real power at around 1900RPM and Full 30psi by about 2500RPM i think....I haven ...

sound like a bleed issue, as the engine warms up the air lock volume increases and pushes the clutch in or decreases free-play until it slips. They are hard to bleed as there is a high loop behind the engine that holds air.
The best way i have found to bleed is to pressure bleed from slave nipple ...

if lag is not too much of an issue and you want it to hit hard, check out the GT3071R with the 0.64AR. not for crawling but awesome on the open road.

good luck

Gudday

Trying to get the wagon to pull up better and have done a search and still no clear conclusion.

Which way do you wind the adjustment bolt with the lock nut on the back of the valve? .....in or out to get more breaking power to the rear?
I have extended the bias bracket to match the lift ...

The GU 4.8 brakes are the best, but the rotors are suitable only for a 16" rim (and GU master Cylinder etc) so may not suit your rig........Looks like expensive rubber you have on there and I doubt you'll be keen to buy that again!!
Sweet build.

so do you adjust that nut to tighten the spring to get more braking to the rear? i want more rear braking too but manual doesn't tell me which way to adjust it and don't really wanna fawk anything up ha
loosen the 2 bolts that hold the bracket to the diff housing and move it so there is more ...

gudday from what I can gather there are 3 types of GQ engine.

the silver top pre 94 which are great, the black top post 94 which are good, and the black top TD42T which are best.
As for block differences all i can say is between the silver top and TD42T there are no differences in structure i have ...
