    Hi Grinna.

    I spoke with you last year re your conversion.

    Its still in my list of 3 engine options and as you’ve fitted more, heading toward my preferred option.
    Im just having my BP51s’ fitted today, so that is now everything short of my focusing on the engine and possible transmission swap.

    Can a 3.2 crate engine be sourced at all for this conversion, or do you prefer used due to the end cost?

    Thanks mate.

    Check out these cars: You have been blocked

    Couldn't agree more! It amazes me how good these vehicles are when it comes to serious remote outback travel. You can pick one up for under 20K and keep your PUMA for everything else you do in it other than the serious off road remote work. It would work out cheaper in my opinion than modifying your PUMA.

    No other Landrover out of the box can come close to a Perentie.

    4BD1 Isuzu 3.9 litre 4 cylinder motor that can be fitted with a turbo
    Fully galvanised chassis
    some with PTO winches
    some with long range fuel tanks
    some with dual batteries
    external access storage lockers
    RFSV has all the options plus 4 wheel disk brakes and power steering

    The best part of the Perentie story is that they were designed for Australia and built in Australia.

    I haven't seen or heard of many Perentie owners wanting to swap out the Isuzu 4BD1 for another engine. Could be that they are very reliable and good for 1 000 000kms if looked after!!!!

    If you really want to spend north of 20K on your PUMA why not look into the turbo 4BD1 option when wanting to replace the PUMA 2.2. My only concern is that the PUMA gearbox might not be able to manage the torque of a turbo 4BD1 but if you are prepared to change the gearbox to a compatible 5/6 speed option it would be an exceptionable reliable remote outback vehicle .

    Heaps of people go on about the 4bd1 engine. Ive driven a few isuzu’s with the engine, cant really say i was very impressed. A 200/300tdi engine is better. Plenty of 200 and 300tdi engine have done huge kms with little or no issues. But i wouldnt put either in a puma, Just saying putting in a 4bd1 turbo in a puma would have disappointing results.

    Can you get Euro 4 compliant 4BD1s?

    Id like to get an engine that is just as capable and then some as my Puma, but is less stressed.

    The work will be done by a shop, hence my enquiring if anyone is doing this at the moment, vs my having to blindly reinvent the wheel.

    My 2.2 with BAS 170 tune has and is great, but a little underpowered for my heavily modified and heavy Defender. I really enjoy improving on the factory capabilities and modding my vehicle. Most of what has been done has been done by me, but an engine swap is way out of my league. I could remove an engine, but getting a new one running and set up correctly is for the professionals.

    My Defender is a keeper so I want the best engine and gear box option for my specific set up that I can get, for remote touring and not being afraid to tackle the high country tracks.

    Hi 200defenda,

    As you can see from the quote by Baytown who started the thread, he is concerned about the reliability of his Puma for remote travel and he has only 200,000 kms on the clock.

    If you have driven a 4BD1 landrover in remote areas of Australia I would find it hard for you not to be impressed with the simplicity, reliability, fuel economy and work horse capacity these engines offer. As far as high country goes the amount of torque generated by the 4BD1 with a well set up turbo is very good and would provide more than enough power to climb all day. I have driven 200 and 300tdi engine Landrovers and while they are a good engine and a lot quieter than the 4BD1 they can not match the torque reliability and simplicity of the 4BD1.

    In my humble opinion it is these qualities that make the 4BD1 powered Landrovers the best remote Australian outback travel Landrovers.

    As I said Baytown could do a lot worse than buy a KLR turbo Perentie and just use that for the remote travel and high country work. Keep the Puma for the everyday stuff. Probably work out cheaper in the long run and you end up with 2 great Landrovers instead of one!

    As far as Euro 4 compliance - probably best left for the latte sipping mob to pontificate over!

    Regards Warrick.

    Personally, the Puma seems like a very tough and reliable engine which is well proven to avoid major problems, but each to his own.

    Isn't the issue that you won't get engineering approval to fit a 4BD1 to a Defender of that era because it doesn't meet emissions requirements? I don't think you can even fit a TD5 to a Puma Defender.

    But that isn't what you do.... the idea is to fit a Defender body onto a Perentie / 4BD1 chassis. If the additional seating is required then Engineering Cert would be needed for the seat belts & seating capacity change.
