diesel conversion fo a FJ 40

Not worth doing imho. You should get around 17l/100km from the petrol and with a diesel you will not have the same level of performance and consumption would be around 13l/100km.

What do you call Reasonable $?

Most conversions wont get any change from about $5000. Then if you go a Reco motor instead of one from wrecker, than it would be more.

Better cheaper option if you want to keep the 40, is find one with a diesel in it, adn put your good bits off yours onto it. then sell the old one.

you could always go the way of the person in 4wd monthly and use a toyota turbo 4cyl diesel - but then again go ape and shove in a diesel turbo v8 - dam the consumption - they go sooo good and sound even better. you would be better off trying to find a 4wd which came with a diesel as standard and settle on that. keep the fj40 for playing. rgds

Thierry I think you need to use the gearbox off the 13BT or 3B as well.

The 2H 6cyl diesel used in the 45,47,60 series should drop right into the original engine mounts and bolt up to the existing gearbox as they both run the same spline and input shaft length.
Even a good engine swap can take months to sort out and always costs more than planned.
Personally for the CSR I would sell the 40 and buy a HJ75 for $7000-9k or a HJ60 for $5000.
