Diesel engine for 100

[DuckLN]

Personally, I'd import an HDJ100...

X2

I had a dodge cummins ISB and loved it. Front end was a PITA. I replaced upper and lower ball joints. Had it aligned twice. Put new BFG factroy size tires on it and still couldnt get it to track down the road properly. SOLD. Now rollin a quiet ridin 2000 LC (I like to sneak up on things)

I'm getting about 21-22 mpg.

On a strictly only highway driven fuel tank i could probably do 470 miles to 500 miles that is driving at 65-70 mph. Same fuel tank size has the V8

How many MPG do you expect from a diesel engine in your 100?
the old TB's and Cummings are very reliable, but i am not sure that you can obtain more than 18 MPG in a LC100 with them.

I suspect you could spend upwards of $15-20k, or even more, for a top notch turn key conversion.

Unfortunately for a 1HD-FTE swap it is not only a question of money, but availability of a wrecked LHD HDJ100.

Sure if you are nuts and very loose on money you could buy a fully operationnal HDJ100 from Europe, they are around 20,000 Euro, have someone dismentle, cut and crate the truck (2000$ Euro) and shipped over the Atlantic (4000 Euro). At this price your better off keeping the V8 LC for weekend and DD a TDI.

For this to be a affortable but still expensive converstion you need to find a wrecked HDJ100 with a motor that still runs for cheap.

Forget about getting a RHD and swaping it in a LHD. Too complicated IMO.

personally, I've already started my HDJ80 piggy bank and will look towards importing one in 2015, when you can do so for a 1990 with relative ease. Not that it will be cheap, but at least you can do it "legally" and without having to cut it up into pieces.

In my 2500 with 35" Nitto Terra Grapplers I routinely got 17-18 around town about 20-21 on highway if not towing or loaded down significantly in back. Stock sized tires or some that are not as heavy I got 18 around town and 22-23mpg on highway with the overdrive engaged.

I also did the slight timing advance trick...but it was a great motor and never had any issues with my transmission...and the rear end was solid as well.


when I had my FJ60 was thinking of conversion...with the Cummins I would have to do a spring over to allow enough room for the deep oil sump so it did not get bashed against stuff on the road or entering driveway....I was just going to pay turn key to Profitts. Then decided maybe a Mercedes Turbo Diesel...same one use in the 300CD Turbo...5 cyl and near bullet proof. The power band is a bit higher as it was built for high speed autobahn cruising...but you can raise the pressure on the turbo and increase the HP and Torgue significantly without getting close to the limits...it has really low boost in the current configuration. Would not have been much quicker on highway than my 2F up to 60mph and might need to rev up the engine to higher RPMs offroad...but was a good compromise...with parts readily available, lower price than Cummins conversion...though for parts and all around the Isuzu was not bad choice either but was about as expensive of a motor as the Toyota versions.

I think I am just going to save some money and then sell my 100 series and either buy a 70 (HJ75 or maybe in couple years HZJ75/79)series with diesel or do a FJ45/60 depending on what I find and want at the time.

Had that on my old 80, worked great but would go NV4500 if I was doing it again. But with the OD on the 700R4 I got 15-17 around town and 18-20 on highway.

I miss the rumble of the old 4BTA but love the clackety-clack of the turboed 1HZ on my troopie

Cummins turbo diesel (6 cyl)) they put int he Dodge 2500 with Allison or American rear end they also use in the Dodge 2500. Easy to get parts...near bullet proof...and great performance for HP and mostly Torgue.....and mate that with a 5spd or 6spd auto tranny.

Forgot to mention HEAVY AS HELL! You are probably going to need to upgrade the front suspension, drive lines, rear end....etc, etc to handle the increased torque and not be replacing parts every 2 years or sooner.

Total waste of money in my opinion, you will never see what you put into it when it comes time to sell.

Very interesting and informative stuffs from every one, with gas price hovering $4.50 with no ending in sight in SoCal, but appears to be not cost effective. Not only that, California Bureau Automotive Repair imposes a lot of restrictions to swap like this also, in the end it would be too complicated. I would have to drive the heck out of the 100 in order to get back all of the costs spent on swapping.

we are talking about dreams not reality..... that is what I want...but price for motor, price to convert it and make everything work...is way above the return on investment to make worthwhile even with gas mileage gain would take 30 years to break even....well unless fuel doubles again.

I think at that time a turnkey conversion to Cummins in my FJ60 with adding the 5speed as well...with all wiring, mounts, etc including AC and PS...was about $15,000......for the Mercedes 5cyl turbo diesel around $10-11,000 complete. Still a lot of money. Think I would rather pay $15-18k for a 70 series that is already diesel and take my chances on buying parts from Canada or Australia unless they ever put a diesel toyota in USA.

This is that I am talking about, the diesel conversion, involve a lot of man hours and problems, but if you will obtain good MPG, is OK, otherwise the v8 run nice.

I would love to drive my LC anywhere, but the gas price kill any dream.
Also, before the diesel conversion, need to check your local DOT, because in some states is not possible to swap to diesel, and other states request that the donor need to be years newer than the receptor.
Is funny, but "legally talking" it does not exist any incentive to diesel swap.

Cummins not Cummings

UPPPSSssss
thanks

 

[moooooooo]

well the OP didn't mention a cost or budget, then after my 200 series suggestion, (post #2) said "keeping it realistic".

Deisel here is much much more than petrol (gasolene) and i filled up today on 98 octane BP Optimax, at $1.61 / litre. Diesel was another 30 cents more.

Also, diesel servicing is higher. But, those engines go and go and go. I am not d'ising diesels. I chose MY V8 because i wanted a V8 petrol 5 speed manual.

Yes i know the manual isn't an option over there, but the V8 with a proper exhaust system will gain back any economy issues that plagued the reviews of them.

There is a current thread that some ppl in there say that more air == more gas burnt....but it's not the case.

If you install a free flowing performance exhaust system you WILL get bette economy too.

Why? Because with the crappy restrictive factory manifolds and the hugely restrictive catalytic convertors, the ECU is managing the fuel system by increasing the fuel for the poor air coming in and exiting.

Fix that, then the ECU wont add more fuel and you get better economy and more if the exhaust system has also been has been "tweaked".

I DID get both performance and economy when i got my exhaust and modified my intake.

The next step, is to go LPG...Liquid Petroleum Gas....we have awesome tech here now with LPG. Octane rating is i think 102? 104? someone will know..so it's good for the engine and good for the economy of both the V8 and the environment.

Most car companies here offer factory installed LPG utilising the latest technology.

So, supercharge your V8, with appropriate exhaust mods, and then install the LPG tech and you will get a great car with great economy and performance.
Will you get your money back in terms of cost benefit analysis? Yes. When you are 265 years old. I wish you well! But i am going down this path!!
hehe see you in 217 years!
