I'm looking for a half decent 4wd, at a low price just to go out and play on the weekend and maybe some touring once or twice a year. I know most of yous would probably recommend me getting a 4.2 diesel/turbo diesel, but i just wonna hear some of the good and bad things about the 4.2 petrol and the 2.8 turbo diesel.
I've owned a 1989 4.2 petrol 6 before, it had dual fuel lpg, very heavy on the juice, 30L LPG per 100km and about 20+L petrol per 100km.
I just wonna know if anyone has the same problem, maybe a solution to the heavy fuel sucker and if the earlier GQ's still uses up as much petrol?
And if it's true, what somebody told me before about the 2.8 turbo diesel, just hook up a bigger exhaust, bigger air intake and maybe chip it and it will run sweet??

One last thing, does the GQ come in a 3L Turbo Diesel at all?
Cheers Guys.

GQ only has 2.8 TD and 4.2D from factory, lots of after market GQ 4.2TD around, GQ 2.8 TD not electronic fuel injection, so no chipping possible. Bigger exhaust does help a little, but most of the GQ 2.8 TD would now have a lot of k's and may be nearly stuffed. Never had a 4.2 petrol, but think you would be better buying one if you can't afford a 4.2D or TD.

Hi Tommo,

Check out the RB30 3 liter petrol version as well. Very misunderstood vehicle. Engine and Gearbox were out of Racing development program so very tough despite the rumours (the smaller RB26 won Bathurst outright in 91 and 92)

Impossible to break even when revving them - motor usually good for 500,000ks Cheap to rebuild or replace, very quick when modified and driven in powerband (3000-5000rpm) used 15-21 lit/100k Very easy to "hot" up.
Cheap to buy because they were unpopular as were detuned for Australia but still were remarkable on premium and when driven properly.

Look at my post in thread 34584 or do a forum search on RB30 or Nissan 3 lit petrol.

I personally have one I have rebuilt as my expedition vehicle.

hope this helps
