what do I buy??/

The only "update" you can make is to a 4.2litre GU...... They are virtually the same engine as you have now.......___________________________________

DO you need to upgrade??

If it was me, would go a 96-97 model 80 series with the 24 valve motor...
std with heaps of goodies.

as Voxon said though, the TD42 is brilliant reliability wise, cant be beat. Updating to a GU would just get u lower klms and new body shape.

Personally, unless you want to change to upgrade to an ST or ST-L with all their features then I wouldn't bother to update.
Get an aftermarket turbo kit from one of the major reputable companies complete with intercooler if you wish and you'll have a car which will outhaul the factory intercooled turbo diesel anyday. Nissans factory turbo isn't really optimum and is very low boost pressure. (they really need a larger compressor housing to get the best out of them) and as for their intercooler "WHAT A JOKE!!!!!!"
It's the same i/cooler of the old 2.8 and doesn't even have the fan underneath that the 2.8 came with.
It should be a far cheaper option than upgrading and you don't have to pay stamp duty to go with it.

Hi Big Bear,

I agree with all that replied, I just sold my GQ 1989 mod 4.2 diesel that i owned for years...great car indeed, just hopeless up hills. Now i got this one..in the pic below. Later model with a turbo......what a dream this thing is. Amazing the difference a turbo makes....Hmmm good name for a song that....Id seriously consider getting your GQ Turbo'ed. Much cheaper option indeed.

Just for those that dont know....my old 89 GQ 4.2 D would usually climb a hill in 3rd gear, and sometimes down to 2nd...snails pace !..Same hills now in the turbo one.....5th gear and makes it look sooo easy.

Must have had my head in the sand for years .....FOOL !!!!I love it when you talk DIRTY !

Big Bear go and test the Paj DiD 3.2 it will do everything you want it to do plus has a superior engine & transmission than the vehicles mentioned log on to Pajeroclub.com.au

As others have said - just turbo what you have got - BUT there is a reason Nissan only run relatively low boost pressures on their turbo - it is to do with reliability , whilst the 4.2D is unbreakable it does have a problem removing heat from inside motor ,..... so turbo and an intercooler would be a really good option , would make a top tow & tour vehicle ... I have had a GQ 4.2D and now a GU - this one a petrol (had to have an auto and the 3.0 wasn't released when I got it).

Look at fitting a super charger over a turbo, far superior performance and tourqe and no turbo lag, really great for slow driving cross country and un beleivable for towing. I have one fitted to my 92 GQ 4.2 diesal, and the price is about the same price as a intercooled turbo also no heat genereted and the unit is fully servicable, and you will also be able to run extractors as well. I have towed a 20ft boat and do a lot of ks with a camper trailer and have done over 60000ks with no problems at all. Col
