2.8 GU should not go this good

"As I have posted before I am a retard "
How do you know that you're going to be a retard ?

Stefan,
How is it that you don't want any more power? Whatever you have, it is usually never enough!!

It may not have a chip.
Mine was the same. When they are tuned well, they go much better than people think.
Cheers

With all due respect I believe you will have 5th gear problems in the future.

If your talking about the F3 Sydney/Newcastle Freeway then that climb up fro Hawkesbury River definitely requires a down shift to 4th at least.

I'm sure you can do the trip in 5th as you state, however the load on 5th gear is really too much.

Check out the archives four items on 5th gear failure and the reasons.

My 2.8 Gu is the same as yours in regards to hill climbing on the highway. I believe that due to it's high gearing (4.7 ratio) it can maintain speed and even accelerate up hills whereas the 4.2 will need to change down due to its 3.9 ratio and actually get the turbo on boost to maintain speed. Also because of the high revs the 300ZX box will be fine in fifth as it will not be overloaded. On the highway i drop down to fourth once revs fall below about 2300 (80) and then it will easily accelerate to 90kmph in 4th doing approx 2800 rpm. It will easily go higher in fourth but when your still pulling 90 and everything else has dropped to 75-80 and your overtaking them why bother. The 2.8l is a dream on the highway (it still remains the quietest patrol ever built! - check NRMA reviews if you dont believe).

About the chip, I don't know where to look, but I would besurprised if it had one without the previous owner telling you as I would personally see it as a 'selling point'. Mine isn't chipped and has never exceded 3600 rpm ( NT highways he he) and the amount of times it has exceeded 3000rpm I could just about count on one hand. I have been looking at the chip though as a cure for its shortage in the lower range but am waiting to hear reports on the LPG injection a few members have planned for christmas.
It happiest rev range is from about 1800 to 2800 and this is where I try to keep it.

Keep on Keeping on ya little turbo battler!

Kewl, hope that it does have a chip then as it would just make a good car into a greeat one!

Good luck to mate.

Hi Stefan,

If you look under the drivers side footwell to the right of the clutch pedal, on top of the transmision tunnel and in front of the centre consol you will see a white plastic fitting in a half circle shape, about 10cm long and 3cm dia.ith about 20 or so wires coming out of it leading towards the firewall and dissapearing into the main wiring harness. This is the wiring harness that goes into the vehicles' computer.
The distance between the white plastic holder and where the bunch of wires go into the main harness is about 40 or so cm.
The box that consists of the 'chip' is about 15cm long X 10cm wide X 2cm thick and has about 8 or so wires coming out of it, these wires you will find will be tapped into this 40cm section of wires.
So if you find about 8 or so wires leading away from the main bunch and a box that size about 20-30cm away at the end of them, good chance that you have a 'chip'.
Keeping in mind that the one I am describing is where Motson's fit theirs and the box has 'Motsons' written on it, though I doubt that any of the other manufacturers were putting them in a different spot as this is the easiest spot to tap into the main computer harness.
I would also expect that the box would have something on it that advertises the manufacturers name, though if it was just a sticker, it could have come off after a few years.
The measurements I gave you above are approximate, so if you have something similar, but are still not sure, give me a yell and I will go and get some proper measurements and take a photo as best I can and post it here for you to compare.
It would be good if you did have one, they make a damn good car with one fitted, if you're still not sure, go take a 3lt Pootrol for a drive, if yours feels quicker ( which it should be with a chip ) then you've definately got one.
