    I thought this was about 110’s Isuzu’s vers 3.5 V8s

    High way driving is about the same loaded up with hills wind etc. The V8 gets away when light.

    Around town the V8 gets my vote if it wasn’t for its drinking habits.
    Sand dunes (big ones) the V8 has the edge but not by much.
    Everywhere else the Isuzu wins hands down

    i think that given a turboed isuzu 110 the 3.5 wouldn't stand a chance,.

    ........I mean there it is, a vehicle that is comfortable for a family of up to five with a reasonable amount of gear. Way ahead of its time in terms of suspension. Reliable with what could be considered a minimum of service, but old fashioned service at that, no plug ins here! Generally regarded as the ultimate when it comes to bush work. Something real you can hand down to your son for him to enjoy, all with less than 12ltrs per 100kms fuel consumption.
    The V8 is a fun afternoon having a barbeque and chewing up sand dunes, whereas the Isuzu is a full on self-sufficient adventure lasting weeks with out any other human contact at the best fishing camp ever.

    I have to admit my fuel consumption was terrible at around 18L/100km having said that I do not care as it is only a play toy,I do not drive it in a way that is conservative,fuel settings are at a stupid level....I do know that it is well over 500Nm will be dynoing some time this year..

    I tend to agree. But this thread is about out of the box on the day. Not aftermarket tack on or we would end up hopelessly comparing Nos injected 5ltr twin supercharged V8s with compound turboed BD6s which is an endless argument and revolves around how deep your pockets are.
    For a drive in drive out turbo install of about 4.5K on a BD4 you could have a drive in drive out 3.9 cam thor manifolds and box even with an auto. And that would suck up most of the Isuzu’s advantage.
    Quite simply the V8 has the advantage of revs which is hard to compensate for on the long high sand dunes. But then there’s the fuel.
    Considering the amount of times I try to clime long high sand dunes the Isuzu suites me much better ( and cheaper)
    But there is a niggling voice saying i would love a 5lter v8 twin supercharged with Nos etc. maybe when i win LOTTO.

    eather way. neather are PUMAs so we are all way ahead in the Game.

    I briefly owned a stock 3.5V8 '85 county when I first bought my 4BD1 '87 county.

    The 3.5 made the na 4BD1 seem slow.

    After I turboed my 4BD1 (at a cost of ~$1500 all up), I stored Bojan's v8 county which had a fresh 3.9 short motor with 3.5 heads and carbs. The 3.9v8 seemed like a slug in comparison to the 3.9Tdi.

    So yes, stock for stock the v8 goes better, but has almost double the fuel economy and almost half the engine lifespan.
