    Default 2jz-ge advice needed

    hey guys, I was planning to swap a 3ct in my fj. Due to its good mileage and sufficient power but as kabli 3ct are short in market and civil ones are in pathetic condition mostly I have changed my mind towards a 2jz-ge. I also considered 1g and 1jz but both seemed under powered..
    So I wanted to ask a few questions from people who have already done this experiment on a FJ 40
    1. What is its estimated cost (cost in pindi mithu khan is 75k for kabli)
    2. What is its approximate mileage per litre. (mechanics saying 8-9 kmpl which is kind of fine for me)
    3. Will i need to change differentials. I have stock ones. (some mechanics told me about differential change but i could not understand which diffs they want me to use.)
    4. Will it couple easily with my 5 fwd 4x4 gear box.

    I off road hardly once a month maybe. That too casually and not hard core. So off roading is not my main concern.
    You input will be highly appreciated.

    I'm of the personal view that an engine does not turn a car into a death trap. People turn their car into one. Often, it is through neglect; by choosing to not upgrade or refurbish or revisit worn-out essentials like brakes and suspension, when they bung in a swanky new engine. Other times, it is by driving irresponsibly; endangering their lives, as well as those of others. So let me state: the 2JZ-GE (or GTE, for that matter) is NOT a death trap per se, on its own.

    Regarding the 2JZ-GE engine, it's a good powerplant which is smooth, offers good power, torque, and is reliable. In essence, though, it IS a 'car' engine at the end of the day...whose best application is for medium to large sedans.

    In off-roaders and SUVs, there is more of a requirement for lower-revving engines, which deliver peak power and torque at significantly lower revs. Since you're planning to use it in an FJ40, you probably have some reason why you want to replace a low-revving engine with a higher revving one. You probably also have a specific reason why you're choosing it over a 1FZ-FE (petrol) or a 1HZ (diesel) or a 1KZ (diesel); which are all better suited to SUVs.

    To answer your questions, to the best of my personal knowledge...

    1. Anywhere between 60-85K is about the going price for a 2JZ-GE. This depends on the condition and vintage of the engine and should include the transmission, airflow, wiring, and ECU etc. A lot of 2JZs are advertised as "Kabli" but are actually, rejects from cars that have been fitted with other engines. Careful scrutiny of this aspect is warranted.

    2. It's a 3000 cc engine, which you'll be using to drive a Land Cruiser. You'd be lucky to get 8-9 kmpl.

    3. You don't NEED to change the differentials, in the sense that it's not a must. You might want to consider this aspect that the 2JZ (mostly used in Crowns and other large sedans), drives a very different sort of diff, from the heavy, immensely-robust FJ40 one. Most people choose to swap diffs too, so as to upgrade them, at the time of engine swap. 60 or 80 series Land Cruiser diffs, and Nissan Patrol diffs are popular choices, in this regard.

    4. In essence, pretty much any engine can be coupled to any transmission. A lot of people have already done this, in some CJs. I've also heard news about this swap (2JZ with manual tranny) being performed in a Hilux, although I have no real evidence of this.

    If you have any further specific questions, feel free to ask. Best of luck.

    One last thing..."power figures" are immensely misleading, and often have more to do with self-satisfaction / bragging rights, than anything else. The application of the powerplant - and its intended use - is the most important aspect to keep in mind when going about an engine swap.

    To illustrate this, my biggest car (a ten foot tall, four door FJ40) has a 4200 cc diesel engine which puts out 130 hp, and is comfortable at 2000 rpm. My smallest car (a tiny, two seater MR2) on the other hand, has a 1600 cc supercharged petrol engine which puts out 145 hp...and is always at its happiest near the redline.

    Different applications. Different needs. And different ways to address them.

    Thank you sir for the detailed reply.. It was really helpful... I want to go for diesel too but the initial investment is too big.. Drive and power are not an issue here as the original 2f engine has a pretty strong ride.. But sadly the petrol figures make me think twice before taking it out for a spin.
    I saw a few fjs with 1g engine and their owners were satisfied with the ride.. But i wonder how a 2L engine can pull this giant vehicle.

    ive had 3ct and 1g engines both in my cj5s. Although both of the engines were OK for a short chasis vehicle such as a CJ5 but wont recommend for a fj40.

    Currently i drive a rkr with its original engine that is the mighty 3F and most of the time either my fuel tank is empty or my pocket. As per my limited knowledge and experience ill recommend that u go for the 5vz which is 3400c petrol engine out of a prado, considerably torqish and a little lighter on fuel. it gives around 8km/l in a frnds fj70.

    last weekend the price was 90k.

    Hope this helps
