Outer Limits 4x4 Board

Well, I've ordered a Turbotech and boost gauge off Ebay so I will fit them and see what happens. Does the Turbotech come with setting up instructions? I understand that the Isuzu has a stock operating pressure of between 14 and 16 psi. Is this correct and is this what I should aim for? One more ...

Sounds good, I will give it a go and post the results. Thanks everyone for the input.

If you relocate the actuator hose, is there an optimum position for it to be placed for instance, reletive to the flow of air to obtain maximum benefits? Is the best all round 'package' to relocate the actuator and fit a Turbotech along with a boost guage? I also understand that some benefit can be ...

See http://forums.lr4x4.com/index.php?showforum=15 for lots of info on EGT gauges and Thermocouple differences. I have had a look at the Lr4x4 site and it hs some good info. Can anyone recommend an aftermarket complete kit and supplier that will suit the Isuzu? I prefer a recommendation for a kit ...

Valid points here guys, thanks for the input. I have only made some reletively minor adjustments at present and my intention is to maintain reliability of the engine before anything else. To date I have: Installed an intercooler off a Range Rover 300 tdi as this fitted straight into my vehicle ...

The pin marks indicate that there is still a gap of about 4mm between the top of the wear mark and the shoulder of the taper pin. I've already adjusted the diaphragm and star wheel. Is it worth touching the spacer? I dont want to overdo things.

I flushed out the intercooler with degreaser yesterday and you should have seen all the crap that came out of it! Re-fitted it to the Rangy and the mid range torque has really improved. I am going to try and relocate the wastegate pipe to the plennum chamber next. On the pump fitted to the landrover ...

Thanks Guys I am going to give this a go. It now seems that the second hand intercooler that I bought may be blocked with dirt so I am going to flush it out and see what happens.

Cheers Ben I take it by the sensor you mean the vacuum pipe? It runs from the turbo at present. I will give it a go thanks.

Hi I have just fitted an intercooler to my Isuzu 2.8 td engine (1989 ish MK 1) and have noticed a marked drop in performance. I am told that the reason for this is that the boost pressure is now too low and that it will need adjusting to compensate for the intercooler. The turbo that is fitted does ...

G'day, thanks for that info. I have adjusted the starwheel and boost compensator but not the mixture screw yet. Exactly how much is a poofteenth? Is it more or less than an oojimiconk? Cheers

Turned the boost compensator 120 degrees clockwise and the star wheel 270 clockwise. Low down response seems a bit better with just a trace of dark smoke on heavy acceleration. I'm going to fit the intercooler next and see how things improve. Thanks for the advice.

Can you let me know how far to turn the star wheel please without overdoing it? Thanks.

Excellent information, many thanks for that. I will give it a go.

Hi Can anyone help with identifying the location of the smoke adjustment screw on this Isuzu 2.8 td pump please? On the Landrover TDi engines it is located under a small cap in the centre of the cover on top of the pump but as you can see from the picture the cap is not fitted on this particular ...

Has anyone ever tuned the fuel pump on an Isuzu 2.8? If so is there a thread that I can view on the subject? Cheers
