Default Upgrading the GQ diesel to GU petrol

I'm new here so first off, G'day all!

I've currently got an 88 GQ TD42 that I've had for a couple years and I'm looking to upgrade it shortly to a Petrol GU. I want to keep the price between 10-15k, and the car wont be a daily driver, purely for weekend 4wd/camping/fishing/hunting.

Obviously in my price range there will be more 4.5 than 4.8, is it worth holding out for a 4.8 or getting a higher Km 4.8 over the 4.5??

I've noticed most are automatics, are they troublesome? worth keeping sticking to a manual?

Lastly LPG, not a big fan of it but most on the market are duel fuel, does it cause issues? of the two (4.5 and 4.8 ) is one better suited to LPG??

Cheers

Well , i bought my tb45 at 70 k it is soon to be 220k.
Serviced regularly, Auto is fine, had a new rad and viscous about 80k, had tapetts adjusted twice, runs at 82 to 84 deg ( up near 100deg up hills and 40 deg days), guttless as all F### up hills, going great. cheap to run on gas but you have to factor in 2 replacement gas converters and a new gas sender and a few other minor lpg issues.
I am hoping to move it on at 300k, only thing i don't like is dropping back to a crawl up hills with a 2 ton caravan on the back other than that its great, Rod

If you're patient, 15k should get you a nice 4.8. They're more powerful and use less fuel than the 4.5, but they munch heads on gas.

Maybe he wants to double his fuel usage?

I suspect he means upgrade an 88 GQ to a younger GU. The choice of petrol is kind of dictated by the limit of his budget unless he wants to go down the 4 cyl diesel path..

Thanks for the replies so far, fuel usage isn't an issue as I have another car for a daily, truthfully I've driven my GQ less than 10 times this year, it's done less than 5000k in the last 2 years, I'm honestly just after something a bit newer (probably for for a 2000ish model GU) don't want the premium price of a TD42 and not real keen on the other diesel options.

Thats what concerns me about a 4.8 since 99% of them seem to already have LPG fitted

If you only drive less than 5000 km a year why the need to upgrade. Is the gq in poor condition? We are the same, our gq is our fun/ camping car. And being a bit older and cheaper not so upset if I get a little scratch or dent.

Ive got young children who are now old enough to want to venture out with me, and I want something a little more comfortable/quiet and probably a little safer, plus my daily drive will soon be a company car I'm only supposed to use mon-fri so the 4WD will probably see more frequent use... realistically it is more of a "want" than a "need"

Just my opinion but we travel with our kids no worriers in gq and personally sometimes it's better the devil you know.

My GQ is '89 and the newer ones are much nicer but out bush the GQ is that tad smaller. If I changed now it'd also be a 4.8 as I only need it for holidays and could do with more speed

If I had to change the GQ to a GU, I would go with a 4.8.
My old man has a 4.5 auto and I just cant handle the significant lack of grunt. Reliable yes, simple yes but slow, my god its slow.
Granted, its not a performance car but geez 200hp (if your lucky & when new on petrol not gas) in a vehicle as big as the GU is not good.

One of my mates that I go to the high country with has a 4.5 auto. He has loaded it up with drawers, big fridge, 35" rubber, winch, led bars everywhere. He loads it up with enough beer and food to supply 10 people on a trip.

He has not complained of lack of power. It was on gas which he ripped out and runs on petrol only now. He doesn't tow with it, though. It easily goes where we want (although I confess to worrying how he will stop it on long downhill steep slopes as he hasn't upgraded the brakes at all)

So if you don't need to tow and don't need to go extreme a 4.5 will do you fine.

But run a mile from anything that has gas fitted - petrol only. An early manual unit might have the 5th gear problem so be wary as that may cost you a big repair. An auto would be my choice - fit a Nomad valve body and the sluggish changes will be history, plus you get some engine braking.

If your not going to tow anything, than a 4.5 will be fine. You'll have a lot more to choose from over a 4.8.
