LX450 Cummins 6BT Engine Swap

[Dirty Koala]

And you consider this set-up as a real bargain and torque enhancement compared to the stock FZJ 80 power-pack? No regrets?

bargain? Absolutely not....it’s one of the most expensive conversions you can do. But it is an awesome swap with more power and torque on tap than any other swap out there.

Bargain in terms of economy and fuel range - not project and rework costs. To plan 15000 USD for it is no surprise. Nice to hear that you are max. satisfied with what came out of it.

I was talking yesterday to a local Toyota LC shop doing any expedition custom conversions. Engine, drive line, rig and cabin. Asking them about the total costs... 35000€ for swaping 4.5l gas to a 12V Toyota brand new 4.2 Diesel enhanced to 215HP. They will not implement the Cummins. More power will be restricted overhere by the approval authorities. In case for a LS2 swap no way except privat payed proving trials. And by the way the guys from the shop are fully booked - next slot 2021.

Which injector pump is prefered on the Cummins 6BT 12V? Bosch P7100 vs. Rotary Pump?

 

[maxamillion2345]

The P7100 is the better pump but the VE rotary isn’t a bad pump.

What are the mayor concerns? Noise, effort on conversion, vibrations...?

Have you driven any older mechanical turbod diesels?

In particular, the 12 valves are loud, loud, loud, rattle, tear everything apart with their torque impulses, smell, smoke (very little but it will exist on some level), they start to defuel in stock form by mid 2000 rpms and youre at peak by 2800 which means your powerband is right off idle through early 2000s which is terrific and tons of torque and they pull hard but they drive differently than a gasser and thats something some don’t understand, a 3200 gov spring goes a ways in this, but they just drive different.
I love my cummins but its not for everyone. Id expect someone wanting a cummins swap to have at least driven one I guess.

Yes, for privat I had some long time ago. I had a Mercedes W123 2.0 litre Diesel from 1980. No turbo no speed, reliable, good suspension and chassis set-up, 9litre/100km consumption, brought it down to Senegal and left it there. Before that one a Volkswagen Golf 1.5 litre Diesel from 1977, shaky and fried-out, went to Marocco with, 5litre/100km consumption.
In the past 5 year on duty several 8x8 wheeled tanks 22to on the proving ground with CAT 13 litre 6 inline Diesel, SCANIA or Detroit Diesel. As well as the Cummins 6.7 IBS in a vehicle 9to similar to a HMMWV.
Last year May I bumped into that Lexus from the US, sold in Lithuania. Want to start retirement in a couple of years and intend to have world tourer ready then. When I bought it, it was predictable just to use it as a platform and to change the power pack and build some camper interia.

All I heard so far about the Cummins 12V 6BT does not scar me. I consider it as good option or probably the best solution. Need more torque, lower fuel consumption and much more range to cover remote areas.

I have an 80 with a 6bt and nv4500, I like it but it definitely drives different than a gas engine. I am 37s with and over drive gears in the tcase and stock 4.11 gears. If i could change something it would be the smell and the smoke when you get into it. I live at 7700 feet so a block heater is s necessity for an easy start below 40 degrees.

 

[Dirty Koala]

I have a lot of power upgrades in my build, I fuel pretty hard all the way to 4000 rpm....but that does add to the cost of your swap. #MechanicalMafia #DinosaurPower

 

[maxamillion2345]

3200 is the easy way but if I had the head off definitely doing valve springs to run 4k

 

[Dirty Koala]

I have 60lbs springs, but contemplating tossing a set of conical springs in when I have the motor torn apart.

You don't have to remove the head to do valve springs...yes its easier, but you can just move each cylinder to TDC and then you don't risk dropping a valve.

My understanding is that registration costs in Germany are based on engine displacement. How expensive will it be in terms of vehicle registration to go from 4.5L, which is already very large by European standards, to 5.9L? I'm guessing by your budget it isn't a big deal to you, but I'm curious.

Tax is based on engine displacement and emission. E.g. p.a. for gas 4.5l 1FZ-FE Lexus 14.83€/100ccm for the diesel equivalent Toyota 4.2l 1HD-FT 27.35€/100ccm. A diesel particke filter retrofit would be an advantage. Additionally to tax is the insureance depending on factors like parking in private property or road side, home adress urban or country side, vehilce theft rate statistic, user type/drivers age.
Nethertheless I have to discus my plans with the approval authorities. Anyhow it was a kind of struggle to get the stock Lexus enrolled and registered overhere. The counter argument has been different emission data of the FZJ 80 european version than the US version. Finally I got data sheets from the US from a US-car importer which worked out fine.
What I know for sure is that this company gets engine swaps passed and approved up tp 215 HP but they do only 1HD FT(E) mainly for the LC 105 --> europe@toms-fahrzeugtechnik.de .
But never heard about someone over here successfully swaped that 6BT into it.

In my state (Utah) as long as the vehicle is 1997 or older, the clerk at the DMV just comes outside and looks at the engine and says 'yep that's a diesel' and your title gets updated to diesel. Every state is different...back in NJ it wasn't that easy..

What to face on the electric and hydraulic? Obstacles like starter wiring, tachometer, radiator fans, heater plugs, clutch zylinder ratios for NV 4500...

All of those have been documented in my build thread linked above. Have you read through it yet?

Not all yet, I will go through it in detail and ask you afterwards...
