J**p Liberty 2.8 CRD into a Cruiser?

[Chamba]

Hello all,

Has anyone ever put a J**p CRD into a 40 series? I LOVE my wife's 2006 J**p Liberty CRD and it is a fantastic, powerful and torquey motor. It would really be well-suited to a Cruiser and they are readily available in the US. Any thoughts, besides the obvious J**p factor? Liberties weigh nearly what a Cruiser does and get 33 MPG on the freeway with 3:73 gearing, so seems a good choice.

Just as a side note, if Toyota sold diesel in the US we would never have bought a J**p for her. However, the choice of diesel 4WDs in the US is fairly thin. Just putting this out there to pre-empt the inevitable flaming.

The grand cherokee comes with a diesel. Is it a bigger engine?

The 2.8 just sounds too small.

Toyota use a 3 litre to pull around the Prado which weighs more than an 80 series.Nissan,Isuzu,VW and all the other diesel vehicle manufacturers are doing the same in most countires outside the US
VW are using a 2litre on the Amarok

The engine certainly has a lot of fans in oz as well. The thing I would baulk at is the complexity of the computerised common rail diesels.

It would go very well in a 40 series.
But a 1KZ TE would be easier and it would be all Toyota

I agree Rosco, however the CRD is much more available in the US. It produces 160 HP and 295 Ft Lbs of torque out of the box and with a simple upgrade from Green Diesel Engineering in Wi. it will pump out 330 ft lbs and nearly 200 hp. Our Liberty is a rocket, even towing a heavy trailer. The Liberty weighs over 5000 lbs (like a 40) and is rated to tow 5000 lbs in the US.

The Grand Cherokee comes with a 3.0 litre V6 CRD which is also nice but cannot be rebuilt due to the ceramic cyls. The 2.8 puts out nearly the same power but is a cast iron block. The Dangler comes with the 2.8 down here and people chuck big tyres ('big' by Aussie standards; training wheels by American standards) on them with lifts, off road gear, winches, bull bars, camping gear, etc. and they haul well while still getting 25+ MPG. I'm certain it would pull a Cruiser like mad.

I wonder what it would take to make a bell housing to put a 2.8 CRD onto an H55 or to stick the Cruiser transfer case onto the J**p 5 speed auto box? The computer does not scare me as it is actually simpler than my Vortec was and I managed to put that into an HJ47 with no dramas. All it takes is a bit of care with the wiring.

Half the benefit of a diesel (to me) is the simplicity. Newer common rail engines don't offer that.

While I can understand what you mean (and agree to some extent), diesels are particularly well-suited to computers due to the latent BTUs which can be squeezed out with good air/fuel mix.

Your 1HDt uses about 10% more fuel than the very similar 1HDT-FTE. Granted the FTE is more complex but I have driven them with thousands of miles of horrible abuse in the Tanami Desert which run just as well or better than their non-EFI counterparts.

I think that the issue really comes down to the quality of the components and design. Buying a European EFI diesel does make me a bit nervous but buying a Jap (or even American) efi diesel does not.

Sure you can't fix it on the side of the road, but then I'd bet you seldom carriy a spare injector pump for your mechanically injected diesel and if that goes out on your 1HD, you will be just as dead on the side of the road as you would be if you had a bad computer.

If you can get the computer to run without any of the body wiring, then the rest is just nuts and bolts.

 

[crushers]

agree completely ... one wire run for me.
although the KZ is a Toyota motor, parts in North America are a bugger to locate and trying to find someone that actually knows how to fix the electrical when it goes sideways is next to impossible.
and a KZ will not return mid 30s US mpg, no matter what you do to it. so far, in Canada, low 20 US mpg is being reported.

As a side note, there is one less toyota diesel in my family now. 1KZ-TE (intercooled) is gone, replaced with a 3 litre commonrail V6 diesel pushing out 180kw and 600Nm.

The V6 uses less fuel and has 26,000km oil change intervals.

I don't thing any 4 door prado will weight as much as any 80 does ..

 

[crushers]

damn close there buddy, damn close
LJ78 - 1920 kg
KZJ78 - 1930 kg
HZJ81 - 2100 kg
HDJ81 - 2260 kg

close enough considering the engines that are powering these whales are 2.4L vrs a 4.2L

 

[Dougal]

What does your 80 weigh Tapage? I'm guessing 2.5t minimum. Toyotas factory figures I think are without fluids, without seats, without tyres etc.

 

[goldchaser]

My brothers nissan patrol is a 2.8 fact turbo 6 cyl,big car-small motor,it goes ok if you keep the revs up. Bugger all torque.
If i was going to do a diesel conversion on a 4 door style cruza i"d go something around 4ltrs up.

IDI Nissan RD28T isn't quite the same as a modern CRD though. Less power, less torque and more thirst. The straight six does sound sweet though.

The curb weight of the 150 series Prado has hit 2435kg http://www.toyota.com.au/prado/specifications/kakadu-turbo-diesel

Prado gets 8.3l/100klms vs the v6 diesel Jeep Grand Cherokee 8.3l/100klms.

Incorrect,they advertise a curb weight which means ready to roll.Without seats or tyres Dougal,would mean its not a vehicle
Toyota also use the govt fuel consumption figures in their blurbs.

 

[crushers]

how are the govt fuel consumption figure arrived at?
actual testing on the road or mathamatics and theories?

I think they have city and hwy cyle that is replicated in a lab and combined to give an average.
You cant actually attain the same conditions road testing a vehicle. One day the traffics heavy ,next day its not type of thing.

I remember the 105 series and 79 series 1HZ figures were pretty close to the real thing.

There is a bit here which basically confirms what I said

I mean my 80 with bumpers/ steps / side bars / winch / double batt etcetc etc .. still move pretty fast .. can be done with 2.8 engine .. honestly I don't know but don't think can be the same ..

Toyotas figures show a 100 series around 2,400kg. Put a stock one over a weigh-bridge and you get 2,800kg.

If you pulled out the seats, tyres and all fluids you'd get close to the claimed figures.

80 series owners report much the same.

Official fuel consumption figures are done on a rolling road which is set to mimick the vehicles weight and aerodynamics. They are driven through a prescribed cycle (depends on your country) for urban and extra-urban (highway) driving. The fuel consumption isn't actually measured, they measure the CO2 exhaust emissions and calculate fuel use from that.

The "combined" fuel economy figure for a vehicle is the average of the urban and extra-urban fuel economy tests. Manufacturers have to use these fuel economy results, they also have to state which test they used (ADR vs EPA vs japanese vs euro) as they are all different.
