    Default Engine Swap in 2005 Prado

    ASA PW Fellows,

    A friend of mine wanted to swap his weak D4-D motor in his TZ 2006 Prado. Similar engine is available from a nose cut and complete swap (engine + Transmission) will cost 375K, is that reasonable cost based in ISB?

    Also if we opt for a petrol engine which engine model you guys suggest with a price for a complete swap. However, do we need to swap the differential also in case we convert it to petrol as someone told me point that for diesel to petrol conversion one has to change the differential apart from engine + transmission swap.

    Appreciate your feedback with a rough price idea.

    The best option is to overhaul the current motor which is a very simple do able job. but do go for a complete overhaul kit containing each and every bit like head bolts and else.
    also put the new nozzles.
    the 1KD motor is a Gem...

    if you want to swap by any chance only go for a complete half cut of 1GR which is a bolt on fit.

    A 5VZ might not be a bad option either.

    5VZ is a cheaper option but a bit older technology wise .

    1gr swap will cost you 5lacs but what I know is 5vz is suitable amd more economical swap this engine also comes in prado originally.

    Rebuilding the stock engine is not that difficult all you need is to have a good person to work on it .
    I have rebuild couple of them with my hands here at Toyota and they working perfectly fine .
    All you need is Name:  ImageUploadedByPW Forums1426162115.844092.jpg

    Or you can have a 1kd conplete block way cheaper than the swap.
    And swapping a patrol engine will be the last resort .

    @joinami...ironically there is no substantial difference between IKD block swap or going for complete petrol engine that includes engine+gear+differential+fuel lines+ECU+front suspension+fuel pump+ etc...people are recommending to go for petrol engine instead of putting in back 1KD

    You dont need to get a front cut for the swap, just get engine gear, ecu and pump.. its easy bolt on swap and 5vz is a 3400cc problem free engine which needs zero maintenance and care.. but on the other hand 1ld needs alot of pampring and maintenance. So I again advice you just swap in 5vz engine, investing in 1kd is not a good idea.

    If you really want to go patrol than for a trouble free and long lasting swap
    You need a complete :-
    -Engine
    -Gear
    -Transmissions
    -Drive shafts adjustments (may be)
    -Complete uncut wiring/ECU
    -A 6 cylinder fuel pump +Fuel Tank Fitting etc.
    -Redesigning the power steering lines
    -Redesigning the A/C lines
    -Redesigning the Radiators Hoses .
    -Redesigning/Connecting The Clutch cylinder lines.
    -Complete dual exhaust set up for V6
    -Air cleaner Box with complete rubber hoses .
    -Engine Rubber Mounts .
    -All new Plugs .
    - Thrust Bearing
    - New Filters.
    -Front & Rear Engine main seal ) rear seal leakage is common in 5VZ) engine .
    -All new Belts.
    -New Water Pump .
    -Patrol RPM meter/Engine Check Light Option .
    -All electrical Sensors.
    -Redesigning the Radiator Fan Shroud. Make sure you get a 5VZ engine from Prado donor nor from hilux as both have different sump and fittings .
    - A good Mind to work
    -And few bits more ...

    Must do the compression test on all 6 cylinders before paying money to the engine guy as we always do the compression test before removing engine from car and attach the result and mileage with the engine when ever sending some where .

    Best wishes for the Prado .

    What about 1GR-FE instead of 5VZ?

    @mallic

    Believe me you have to do more than That list to have a trouble free swap .
    List will almost be the same for 1GR but if you lucky you won't have to change the rear seal on that as we never have any issue with that rear seal yet .
    Also timing chain will make your life a bit easy .
    And having a 1GR you have better car so called market value wise .

    If I have the subject Prado

    My choices will be

    1- 1KD-FTV ( overhaul )
    2- 1KZ TE
    3- 5L-E
    4- 1 GR
    5- 2TR
    6- 5VZ
    7- 3RZ

    All obove are almost bolt on except 2TR .
    Staying 4 cylinder will ease few things .

    Any how you will learn when you or your friend start the work .
    And never ever opt the same guy to fit the engine from whom you buying as he will not tell you of any missing steps or faulty things .
    Do lot forget to have diagnosis socket when our ustaad electricians are working .
    And look for all codes at the end of swap .

    Its up to you, if you want to spend more money and need more power furthermore its about fuel consumption too 1gr hardly gives 6kmpl..
    Every vehicle which has a 1kd eventually gets swapped with a 5vz be it surf, prado or Vigo... some people do swap in 1gr engines but thats because they want to use it for rally or just they want more power.

    If you want petrol engine only then swap other wise fix your 1kd. Swapping another 1kd is not wise.

    A friend recently swapped a 5vz in Vigo and he is more then happy and it is problem free swap.

    reading the whole thread have to say suggestions by @joinami are the most sensible and well explained. from a mechanical point of view swaps are not good, and just doing a swap especially from petrol to diesel or to use 5VZ because someone else did it is not advisable at all.

    better option would be get rid of the car and getting something that suits needs more.
    If everything is coming your way, you're in the wrong lane!
