I own the 2000 105R 100 series landcruiser with 4.5 litre 6 cylinder petrol and I am happy with it.
I have an opportunity (via a friend) to upgrade (upgrade ??) to a 2003 100 series 4.7 litre V8 petrol.
Both vehicles are white in colour and have identical
miles and condition. To change from the 6 to the 8 will be NO inconvenience nor will it cost me any money.
I do NOT town anything apart from a 6x4 trailer with garden rubbish once in a while. It's basically a vehicle to cart my wife and 4 kids around in, with a mix of town and open road driving.
What will be the benefits from going to the V8 ?
My thoughts are I will use less fuel because the V8 motor will be revving a lot less for the same work. My 6 cylinder gets around 17 L per 100 km on the open road with a small mix of city. I understand that the V8 petrol in identical situation could get around 13 L per 100 km ? Is this right ?
Is there any more maintenance with the V8 (2 more spark plugs obviously !)
are there any issues with the V8 that need attention /
Thanks for any help......

3 years newer - this is a no brainer, do it if it is as good as you say - do it

That is an advantage (the years), but not the be all end all.

I have just done the same thing. I have an 80 series running on dual fuel for the past 7 years it has 433k on the clock. It has been and still is a great vehicle it has been used as a work vehicle towing a large dual axle trailer with a large ride on mower and assorted other grass bashing gear. It has also taken us around the country and to some very remote spots. Its still going strong.
My wife has a 2002 commodore
sedan which we decided to replace. We decided to buy a 100 series to become my wifes work vehicle and our tourer. She insisted on having an auto. Budget 28k max.
I
test drove, off and on road auto non turbo diesels, auto 4.5s, not very impressed with performance. I was never convinced that an auto 4x4 was the way to go, less control off road etc. Drove a couple of auto v8s,
well I gotta tell you I was hooked straight away.
Figured if the swambo wants an auto I'm having a v8. Anyway the way she drives she will never wear it out.
I found a 2003 5 speed auto local to me in great condition with about 150k on the clock with a complete service record never been off road, $25000 private sale.
I am not one for accounting for every drop of fuel I use as I figure its just part of running a vehicle of any sort. I have put about 3000 k's on the clock and driving it carefully it does not use as much petrol as the 80 does running on
petrol because its not working as hard. The 80 sitting on 110kph in fifth will rev at about 2700, the 100 will rev at about 2000 revs. Sure it will use substantially more fuel if you drive it around town like a green P plater in an ss commodore.
The best thing about this vehicle is the amount of power that it has in reserve, bearing in mind that the difference in motor size is only 200cc.
I can't see maintenance costs being any more than the 80 with the exception that the v8 runs a timing belt not a chain so there is a bit of cost there when it needs to be replaced. The timing belt had just been done on
mine before I bought it.
I guess the best thing that you can do is
test drive the 100 in all the conditions that you would drive your 80 in and you make your decision based on that.

Sorry I should have indicated that my old 80 is a 4.5 which is essentially the same engine you have in your 100 and I should have said 'your 100" in the last line of my reply.

My thoughts mirror yours, I guess I just need to hear it from someone else.
Can't test drive unfortunately. I said it was a mate's but he's passed away and it's part of the estate I am offered (buy then drive option only, but I trusted him to look after it)

G/Day Mate, I own a 04 100s 5speed auto 4.7l V8, They are a dream to drive,
Reasonable economy for size of vehicle, (13l/100 might be a bit keen, more like 16s 0n average) But at those ks be very aware of piston slap which around these models was a issue for some(Don't let anyone tell you otherwise)
Lift the bonnet first thing in the morning and have someone start it(it must be cold!) If any rattle is evident at all, be very wary,
Google up ...Faults 4.7l toyota V8 and you will see what i'm on about;
They are generally a very reliable engine,but as i say for some" not so good"
Good Luck
Cheers Axle

The only way to solve piston slap Eyspy is to either rebuild the motor,rebore new pistons etc, , ,Or replace!Thats why i'm saying be careful!! listen to it very closely when dead cold, if theres a rattle until it warms then you can bet your left nut its piston slap. Mines had it for two yrs runs like a dream ,but for how long who knows??, Its done 200;000ks also.
Cheers Axle

The V8 has proven to be a very reliable motor, by all accounts.
I don't know if you'd do much better than 15L/100k though, if there's any city driving involved.
I assume you're aware that the V8 is IFS front end and will therefore be a bit nicer to drive on the road than the 4.5 (solid axle).
The V8 has quite a bit more power - and the 2003 will also have the 5 speed auto, which is a nice unit.

The IFS is fine by me, as I am not a ""TRUE"" 4WDer, it's the seats and space I am after, so the smoother ride will be welcome.
Some have said get gas injection done, but I am not sure on this as you then create valve problems and everyone I know that has converted their family sedans to gas has had some problem or another with it. Plus there is a lot of petrol to be had for the cost of the conversion, and I am not sure how long I would keep it for ?

If you get a gas conversion with the V8 you'll also, I think, have the issue of relocating the spare wheel.
I wouldn't bother.
I looked at the V8 petrol and the Turbo-diesel and thought the V8 was a bit nicer to drive and was going to be a bit cheaper in the long run but I liked the range and lower weekly hip-pocket costs of the TD so went that way in the end (about 2 years ago).
I think you might find the V8 will use more like 13-15 on the highway and 20-25 in the city. Depends how you drive it, I'm sure.

The V8 kills the 4.5 in NVH levels and drives better, however for serious off road stuff the 4.5 is still very popular.

What's NVH levels ??
At least if I get the V8 I should be able to easily sell the 4.5 to a serious off roader.
I just need a Toorak Tractor

NVH = Noise , Vibration & Harshness.
It's a common term when reviewing a vehicle. The Lexus/Toyota V8 is a silky smooth engine in comparison to the 4.5 Litre straight six. The 4.5 has a live axle arrangement which is often preferred by serious 4WD'ers...

Well I ended up getting the V8 in question, and have been driving her around for a month now, and I must say I am quite impressed.
The power and ride are much more superior than my 105 series, 6cyl petrol.
I have done one fuel consumption test running around town amd mix of open road and returned an impressive 14.7 L per 100 km. I expect this may drop to 14 or lower on an open road trip.
As I don't 4WD as such and just need the comfort and space, the V8 with IFS is a better option for me.
Just a note. My 2000 model 105 series is now listed for sale on this
forum if anyone is interested.
