LX450 Cummins 6BT Engine Swap

[Dirty Koala]

1. stock Cummins mechanical fan works great. You might need to trim and block off the little nipply on the top left side of the radiator to clear the fan
2. Power steering is easy. A few readily available adapters for the steerin box and then have a hydraulic shop make you a hose.
3. Toyota/Lexus tach requires a 3 signal pickup to work correctly. The 12V motors have a harmonic balancer with 2 pickups. To overcome this you can get a 24V cummins harmonic balancer which has 0 pickups. You then machine 3 equally spaced notches into the 24v balancer. This is a cleaner solution than using a conversion box in my opinion.
4. Clutch Hydraulics: Get a toyota 80 series clutch master cylinder and an NV3500 slave cylinder and then run custon line between the two. on my setup i got both an NV4500 and an NV3500 slave cylinder and used the push rod from the NV4500 with the body of the NV3500 slave to make it all work correctly. You may need to weld in a small spacer on the master cylinder push rod to get enough throw. Pics and details can be found in my thread.
5. Make sure you run two big starting batteries wired in paralell. These motors need lots of juice to start.
6. Wire up your grid heater with a monetary switch on a seperate relay.

Dankeschön, for all that information.
I guess it is a good option to have a e.g. Dodge vehicle to canibalize from.
Which one is recommened...?

E.g. for my Volvo 760 I bought an additional scrappy one to have enough spares...

not really much benefit to getting a whole truck as you really are just after the motor, but if you can get a P-pump 6BT from a 96-97 dodge and get the NV4500 5 speed trans with it.

Thanks for your input.
I have some more questions.
Exhaust:
How did you solve the exhaut pipe issue? Did you connect to the FZJ down pipe? Ordered custom parts or self made hardware? Is there any emission control or diesel filter implemented?
Cruise-Control:
Does the cruise-control work? What was modified?
T-Case:
Where did you order the exchange gear pair for rpm increase/torque decrease? Where Hi and Low changed?

1. Down pipe and the rest of the exhaust is custom made by me.
2. There is no emissions equipment on a 12v Cummins. Rules around what you can legally get away with will depend heavily on where the cruiser is registered. I am lucky enough to live in a state and county that allows diesel conversions and for diesel vehicles 1997 or older there are no inspection requirements including emissions.
3. Cruise Control is difficult to solve for and most don't, but there is a way to do it with some overly complicated cam gears...I wouldn’t bother with it honestly.
4. You can get the transfer case gear sets and rebuild kits from Cruisers Outfitters @cruiseroutfit. I actually just picked up a 10% under drive set this past Saturday for my LX450. You will want the 10% overdrive version for your LX after you put a Cummins in.

Hi guys, do you know of which adapter kit to the stock Toyota automatic he is talking about? --> Jonesys Auto Club Video

And there must be an additional ECU for the automatic due to cut of from original engine

I have that, but it is no longer made, your best bet is go NV4500 and get the adapter plate to the stock transfer case, you need to redo the wiring harness . I can also run my Cruise control and love it on long drives .

Using one of those motors you will need an exhaust for a Dodge truck to clear the the turbo from the the fender well, and getting the exhaust in the correct location to have a smooth exhaust pipe

to get the engine in europe is not an big isuue but not easy to find the NV4500...
and will the flange pattern of the engine out of a DAF truck (with a ZF auto) match to it?!

from where in the US can I order the NV4500 (and the adapter kit)?

Concering the diesel engine swap there are some obstacles to overcome. Got feedback from the approval authorities. Mainly driven by national emission standard which do not allow any decline on environment pollution by exhausts as well as on air-bourne sound. Last shall not exceed the dB(A) value of the gas engine in drive-by mode - which is pretty tough. Fuel emission-wise there is e.g. a certain crank-case fume and diesel tank fume absorption requiered that will lead fume to the intake. Light truck do not have that and the cummins will be taken from those. The engine exhaust emission will be validated in an extra test to set-up a data sheet. And on and on ...
I will go for more details!

Only 7% larger tire circumference can be allowed in order not to be forced to enhance the brake torque
