Cummins engine convertion

[paulyg]

Can anyone recommend somewhere to get a Cummins engine conversion? and if anyone has had one done, was it worth it?

[Hodge]

I see a guy near my work just about weekly with a GU 6BT conversion. I'm only going to mention what he says about it.
Does he love it? Yes.
Would he do it again? No f'in way in hell is words in quote.

The amount of $ and hassles he has had to get the car on the road is beyond ridiculous and in his opinion not worth the nightmare. The modifications needed are crazy. You need to severely modify the rocker cover/top of the motor so the bonnet shuts. The sump pan needs to be built from scratch to shape around the patrols steering / suspension components. And then the engineering nightmare with the weight of the motor, which is 500kg-ish dry weight from memory. And there was other numerous things he has mentioned I cant remember right now. I think also the radiator clearance is bees dick...
I know next to nothing about these motors, so this is just coming from 1 bloke that i'm aware of thats had the conversion.

I believe Patrolapart in Lilydale own a cummins converted ute?? I think. Might pay to give them a buzz and have a chat?

Yeah I reckon patrolapart is a good start. Awesome motor suposedly but very heavy and costs and friggn round will be up there. . . Will bloody haul tho. .

I think the 6bt is probably to heavy, I should have stated in my original post, I was thinking about the 4.5L common rail motor.

A customer of mine has spent the last year doing his. Finished he loves it. Balls to the wall he says. Towing a 3.5t trailer and it barely breaks a sweat. 1000nm of torque he says he’s seeing. His dad has an LS Patrol and brother has a 200rwkw TD and both cannot keep up even when he’s towing. But. He does say there is no way he will now do any serious off roading in it now. Whilst he has done everything possible to make it right by the engineers book. He reckons its too front end heavy and not as balanced as it used to be. But the endless power on tap he does love. This guy is good with his hands and said it wasn’t too bad doing the conversion, but some things just come natural to one and not to others.

Thanks Mudski, is that 6 or 4 cylinder?

6BT mate. Fark it moves. He dropped in today. We have construction works going on next to us and theres all these cashed up workers in there pimped up Gutluxes and Rangers with every accessory on them. They were all out the front when my customer leaves, you would have thought it was a 1/4 mile drag strip when he took off. The jaws on these workers hit the ground so hard. Priceless.

We’ve gotta love the South African simultaneous import tubs concept [emoji23][emoji106]
Keen to learn more about how to front axle legal load a decent steel bar & winch on a ripper beast of a 6BT conversion [emoji106][emoji106]

Here's the 4.5. Never nearly heard of or seen these in a Patrol but looks like a bloody good option . .

There was a guy in Shepp who has one and he was setting up a parts upgrade business to support the conversion based on his 24V conversion. He was working at the site I was. His GU was sitting on 37" tyres and looked totally stock. It was engineered in Vic, but to do so, no second battery under the bonnet, no winch, no bulbar. He was 5kg under the max front axle load with no one sitting in it. It was accepted and signed off by the VASS engineer though. Drove like a cut cat apparently and you would not know what you were pulled up against at the lights.

Yeah a 6bt would be nice, but no good for me, I need something I can tour in, and carry a load.
Otherwise a 4.2 or even a 6.5 optimizer might be the go.

After all that work and heartache I thought you were firming for having found a solution?

Our 4.2 may be very reluctantly for sale if you can wait a few months. It's got everything needed for long term remote area touring, including a 3900kg gvm upgrade. With the front e-locker it really is a very capable set up. Have just given it it's 250,000km service yesterday. It can be sold as a package with the Tvan, or as a 'stand alone tourer' with an unused Oztent which fits neatly into a storage space under the tray. Of all the vehicles I've owned our Patrol is the one I have most trusted.I would take it anywhere tomorrow, confident it would get us there & bring us back. We've had it as the second owners, (Telstra being the first) since March 2011 when we bought it with 153,000kms on the clock & a service history dating from brand new to now.

We are in the process of buying an OKA fitted with an intercooled (water to air) Cummins 6BT, and intend getting it's manual gearbox (spicer) replaced with an Allison auto. It's a big job we are hoping a chap in Taree might do bit by bit as an 'on the side' job for us, which may take a while . Once that's done, we'll be returning to Ballarat to make a few alterations to the camper part of the OKA & to sell the Patrol & Tvan.

It's a shame to hear you moving on from the Patrol and Tvan but our needs and requirements change.
Best of luck with it and I look forward to seeing your journey with the new OKA.

Best of luck mate. I know your Patrol setup would be perfect for a lot of people. I’d love a reliable setup like yours.

You ever get any further with this idea? I'm thinking along these lines myself. Been looking at a coil cab ute as a donor vehicle and reckon the Cummins 4.5 common rail would be a pretty sweet partnership for touring/towing with reliability.

My son has bought a 2012 gu in March this year and pulled the 3 LTR out and has put a 4.5 Cummins in it, he’s almost there with a few things left to do including wiring but should be a good thing when it’s done.87426
