Outer Limits 4x4 Board

Hi all,

Looked/searched for an hour or so, lots of info on 2.8 and 3.0, but not much on 4.2 non intercooled models.

Just picked up some Autometer boost and EGT gauges aswell as a pillar pod to put them in.

I have a 99 GU ST, Factory 4.2 Turbo non intercooled model.

Where have people got the feeds for the gauges from ?

The boost gauge i think i can sort out, its more the EGT that concerns me.

take to an exhaust shot an ask em to drill a hole n weld on a nut tot he dump pipe, so u can screw the egt sencor in

If your confident with tools, there's no reason you can't do it yourself. The pyro pick-up point is better off being pre-turbo as it gives a far more accurate reading of the EGT's.

Have a look at my build thread: http://www.outerlimits4x4.com/ftopic165380.php

It isn't exactly the same setup as yours, however it shouldn't be hugely different. I'm not sure what type of probe you have, but mine was a tapered BSP fitting, so all i had to do was drill the manifold, cut a thread then screw my fitting boss in. I used some high-temp thread sealant/lock compound too.

EDIT: If you are going to do it yourself, be sure not to let any swarf or metal shavings go IN the manifold. Might be safer to take the turbo off so you can crank the motor and blow any crap out. Saying that, i know of plenty of people that haven't bothered taking their turbo off!

Thanks Coxy, most helpfull.

ill have a read. If im still not sure ill take it somewhere and ask nicely.

Are you able to pull the turbo off yourself? It doesn't have to come ALL the way off, just far enough that you can stick a rag or something into the turbine inlet/flange and stop the crap blowing straight into the turbo.

Provided you don't snap a flange stud, it should really only be a 1 hour job to loosen the turbo, drill/tap your hole into the manifold, fire the motor once (as in literally just "fire" it once), then slap it all back together.

Or you could do it the "easy" way and put the probe in the dump pipe. Easy is not always best.
