Outer Limits 4x4 Board

Hi judge my plan for the truck is to use as my daily driver and touring rig will be towing a camper when I get one and a car trailer with a commodore on it every now and again. The main reason I intercooled it is I am trying to get the truck ready for a Fraser trip I have planned for later in the ye...

Sorry I should have explained myself better with the blowing air through it I capped both ends with the plastic caps that came on the cooler pushed an air fitting through one end then opened the valve on my compressor the cooler quickly pressurized and blew the opposite end cap off to the one I as b...

thanks again fellas your replies are all helpful. I wish a dyno tune was an option but the nearest tuner I know of is in Brisbane which is 4 hours away and even so I only have a standard pump with no boost compensator so the tuner would be very limited in what he could do in regards to fuel ramp and...

Has a safari snorkel standard air box with unifilter then 3" piping to the turbo. I have removed the intake piping taken it for a run to make sure it wasn't too restrictive made bugger all difference. I do have some pics but can not work out how to get them to upload happy to send them to someo...

So heres a bit of an update pulled the cooler and piping off checked for any blockages, couldn't see anything. Blew 120psi of compressed air through the cooler and it seemed to flow out the other side well. Put it all back together and siliconed all the joins in the piping. Took it for a run and it ...

thanks for the replies guys. just to be clearer my fan is mounted underneath the intercooler drawing the air through the bonnet scoop into the engine bay.The piping is 3" but only 2 short 180 bends so I dont think it should be the problem. I have noticed also my pyro temps are staying hotter on...

Ok so heres the story I've got a GQ TD42 with an older style dynamic turbo kit with the switzer high mount turbo kit. Standard fuel pump wound up running 15psi. Before fittng the cooler my pyro would max out at 530c post turbo probe is 25mm from the dump flange. After fitting the cooler which is 450...

Mate I work at 4x4 wreckers and i reckon next to free wheeling hubs and cv's these are the most common things we sell of GQs They seem to all eventually leak I think its got to do with the heat of the exhaust running right next to it. I would try to get a nice braided steel one made up. Cheers Gary...

Ok I'm looking at building a bigger intake plentum for my GQ TD42 turbo. I was looking at a mates injected petty and thought I wonder if that would fit? So I am wondering if anyone has ever tried putting a TB42E intake manifold on the diesel and weld up the injector ports. If anone has done this wha...

Probably a stupid question but im new to the turbo diesel thing. Is there anyway i can get full boost to come on sooner. At the moment i have my boost set to 14 pound and my truck makes around 10 reasonably quickly but then slowly makes the last bit. I have a 3" exhaust and boost controler fuel...

Pretty sure they arent mate there is actually a large and a small hub in the td42 and tb42 engines aswell. Most diesels came out with a strait blade fan the tb42s have a curved blade.

hi all just got a turbo timer its an older style ARB unit with just a red a blue and a black wire just wondering which wires under the dash of a GQ TD42 i need to join these wires to?

Cheers Gary...

G'day ppls i have a drama that im hoping someone on here can help me with. My GQ 4.2 petrol will wind over and fire but the moment i let the key off it stops i immediatly thought ignition fuse but its fine so went to the ignition relay under the dash replaced that but still no go, then replaced the ...

just wondering if anyone on here know where i can get a 350 holley with race bowl and centre hung float from i have heard these are the only one worth running off road is this correct or will any 350 perform well offroad? thanks for any help u guys can offer...
Cheers Gary...

Hi all Im trying to fit an automatic transmation oil temp gauge to my GQ but cant find anywhere on the box to put the sender hoping someone has done this and can tell me where it goes. Thanks
Cheers Gary...

thanks chevlux. this may be a stupid question but why could i not get say a 650 to run if i jetted it back these motors are a 4.2 so is a 253 and i see plenty of 253's runnig 4 barrels?

Hi i've been noticing a few pretty hot 4.2 petrol patrols on here but everywhere i try to order even a simple mild cam and 4 barrle carby adator just look at me like im a spastic and say they've never heard of it or cant get me anything. So i thought i would turn to the wealth of knowledge that is o...

I'm just hoping someone has done this before or tried and can tell me how hard it is or if its possible at all?

Cheers Gary...
