    Default FJ60 engine transplant

    Hi all,

    I need some advice regarding an engine transplant.

    I have an FJ60 which I'd like to use as a daily commuter as well as an overlander. I plan to drive it to Europe and then Siberia in a year or so's time. Unfortunately I am brought close to tears eveytime I head to the petrol station. I get around 23l / 100kms currently. ...

    I absolutely love the beast but I need to change the engine to something with far better fuel consumption. I've read several posts about the Lexus V8 conversation as well as the much loved 1FZ-FE. I've also come across people putting in the 1HZ.

    The issue I have with all of them is that is that the fuel consumption is not drastically different to the 2F motor I have in at the moment. I'd like to half it and be in the 12l / 100 range ... Based on what I want to use it for, fuel consumption is my primary concern.

    The question I have is if anyone has any experience fitting the Dyna 4B (or similar) motor into a cruiser ... And also if you know anyone in the Gauteng area who has experience doing the conversion.

    Your thoughts and advice is much appreciated...

    Thanks a ton,

    Zah

    having purchased a vehicle which had a botched conversion, I ca tell you that you need to budget at least 50k to do a (simple) conversion. there are so many extras which you wouldn't think to consider when you start down the conversion path.
    having said that, of course its possible.

    However, in your case I think that converting from carb to EFI may provide an equivalent fuel consumption cost saving. Unless you go diesel.

    Zahd, I suggest you contact Bennie Smit, yspen on the Forum. He has been through all the possibilities and spent a fortune in the process as well. I think I know what he will say, but better you ask him yourself!

    I assume that is the 3F.

    Tune it properly and you will get 6-6,5km/l

    That 1FZ will not give you better than 20l/100km

    Going the 1FZ-FE route, will cost you R50k just to get it in.

    The 1HZ will cost you at least about R80k to fit.

    I plan to spend around that figure - I know it seems silly to spend a big chunk of cash on an older FJ but the heart wants what the heart wants

    Which motor could I use as a donor for the fuel injection ... Also any idea what the fuel consumption gains would be?

    Thanks ...

    Going the 1HZ/1HD route would give you 1kl/l gain.

    Everything else will be heavier on fuel.

    Had a Cruiser 80 and did the same thing. Here is what I can tell you for a fact:

    1. whatever you budget, will cost way more.
    2. whatever you read, it will never run 100%
    3. every conversion is different with multiple different custom work that needs to be done to get the lexus running.
    4. Don't do it.... fix the donkey and drive another 200,000km rather.

    My 2cent worth. The flip side is that you will also hear opinions of people that are happy with their conversions and then this is where you have to make the call.

    Oh and by the way, you won't get the projected better consumption.....

    Thanks for the feedback guys - it's for the reasons you all state that I was interested in the 4B motor out of a dyna truck ...

    Any suggestions regarding fuel injection?

    I always wondered about the Isuzu 280 DT engine - that should give a very good consumption, but the engine is a bit pricey ...

    Did an EFI conversion on my ex Hilux - that was definitely worth-while - My father still drives the Hilux ...

    I had a FJ62 with a 236 ADE engine it was great on fuel and that's it....

    Best advies I can give, buy an 80 with the either the 1HZ or 1HDT as soon as you start modifying a vehicle you never stop and it opens you up to more and more problems and custom part which you can't get when over landing.

    If you really like your 60 I'd suggest you do a body off conversion where you fit the 60 body onto a 80 chassis then all your mechanical parts will be 80

    I was going to so this with my 62 and a 1HDFTE 80 but then they stole my 62

    Speak to Mark Watson he has done a few of these conversions

    If fuel consumption is what you're after the best engine will be the 3.0 D4D I know of a guy that did such an conversion with an wrecked fortuner as a donor car

    Great info guys thanks a ton ... Or a 3 ton

    Marco, I like the sound of that - but has the 3.0 D4D got the muscle to pull this truck in all conditions?

    Think this is a very expensive option, but if you can pull it off it would be a amazing combination.

    With R80000 you can do nearly 70000km extra just on the cost of the conversion and you have a standard truck.

    Speak to Mark Watson
    As long as it stays at speaking to him and not having him touch your vehicle it will be fine

    I had a Cruiser with a 2F many moons ago. Got around 7.0km/l with the following mods


    Branch en free flow exhaust with 38 Weber. Also had the head machined to give a compression ratio of about 9.6 to 1. The 2F standard ratio is 7.8 to 1. Match ported the cylinder head. Performance was improved significantly.
    Reckon close to a 20kw gain.
    It is not what you buy its what you build.

    But then you can't run on dodgy petrol like you'll find in Siberia............
