Good honest review, I'm on my second vehicle with the 6.5, this one has the P400 and I'm loving it. There is just something about that note. Missus says it sounds like a Greyhound bus at idle. and you are dead right about doing your research. Overall, a great review...
Yes great honest review, and so true about turning up the fuel, losing the fuel economy. I’m so torn. I have 4l80e auto with 3.9s behind mine and just love it.
I sent my 2015 GU to Brunswick Diesel in 2019 I have done 100,000kms in my 6.5L optimiser now and have never got the fuel economy you have spoken of, the best I get is around 16l’s per 100kms which is rare. Usually mid 17’s to 18’s and worse in city driving. I could really use some contacts to help with advice here in western Sydney, NSW there doesn’t seem to be many people I can chat to for help or any repairers familiar with the motor, any advice people have will gratefully received. Great video btw Thanks for sharing!
Hi Phil, check out the Facebook groups Aussie 6.5l chev diesel and Australian 6.5l chev diesel owners groups. Also some good U.S Facebook groups to, just have a search. My engine must of been running very lean, the pump was still on the brunswick run in settings.
@@craigslistofprojects3451 Thanks Craig much appreciated, unfortunately I have never been on Facebook and have been kind of proud of that fact, but it might be time to change…. I really need some help from a reputable diesel repairer here in western Sydney.. beautiful truck btw love it!
I got my manual 2005 gu patrol converted to a brunswick diesel and love it.ive just done 10,000kms towing a combined weight of 6.2 tonnes of car and caravan...fuel consumption at 110kmph is 22ltr per 100. And around 21ltr per 100 driving at 100kmph. I also had a dyno a few thousand k's ago and it produced 584nm at the wheels.i was told as the engine wears in that figure will rise a bit.. Great engine so far and sounds awesome.
Hi Troy, that's great torque numbers at the wheels. Assuming it's stock on the Brunswick pump settings. These things just chug along pulling weight all day. Nice big lazy V8. 👍
Thanks heaps for the video. We've had our Optimiser for nearly three years. I am still optimistic about getting it right, however it has has some issues. Thanks for the info on where to get parts.
Thanks for the great informative video. I also have a conversion and I'm having the surge issue. My question is did u have to put a flow regulator with the new lift pump? I have been told that it should supply 7PSI but the carter black competition indicates 14-16psi? Thanks
i have a 2003 chevy workhorse winnebago motorhome , first thing i did was move the PMD on a heat sink near the front bumper , the old girl has never missed a beat ,, 6.5 best fuel efficient v8 diesel out there , my rv weighs in at 8700kgs and i pull a 4500 kg trailer ,, still get great milage ons still overtake going up Mt Ousley , Rob NSW
sorry buddy i forgot i have the DB4 electronic pump , I have had to change it out after winnebago did a Tune up on the RV and stuffed it ,, They are very easy to work on ,,
@@13yearsaprepperr.jtilbury.51 Looking at a 95 Monterey with the 6.5. Can you share your general fuel mileage not towing and not in a heavy mountainous area? Thanks!
Great review, I recently picked up a land cruiser hj75 dualcab from Australia that has the Brunswick Diesel 6.5 conversion. Great explanation of everything about it. For me the 6.5 is much better then the stock 2h it originally had, out here in America our landscape can vary from smooth long straightaways to climbing 6 7 8 thousand feet. Plus with our highway speeds people fly out here. So it’s nice to keep up with traffic. My truck weighs roughly 6400 pounds.
They come with a 3076 Garrett , I put a gtx 3584 (ball bearing) from pulsar turbo systems with a .63 exhaust housing, .82 is to laggy (new flange on down pipe is needed for vband ) and grabbed coolant from the heater, also had an upgraded injection pump from Brunswick. Ran great!
You can add a pump and exchanger or small rad (and reservoir) for the interior cooler and it'll really drop the Temps and you can add ice to the system.
13.2 litres per 100km is good for the 6.5 on the open road at 108km. My 200 2008 Sahara with same accessories as yours at 3.8t was getting 15.72 litres per 100 at 110km with motor tune, lockup kit on trans, twin 3inch into single 4 inch
Hey Dave, yes it did pretty well. Especially with the 4.3 diffs, but the more I have looked into the more I realise the engine must be sitting bang on its peak torque. Around 2350rpm, at that speed. Would love to see the figures with towing a camper.
great informative video at least the way it is you can travel AUST without a worry ,as soon as you start sticking big turbos and big boost on you have to start thinking of all the fail points on the drive line PS it sound great way better than my modified td42.
Hi, thanks for great feedback. It was definitely a work horse, happily plodding along. That was the plan to keep it reliable, saying that the torque took its toll on the gearbox so i had to rebuild it. Check out my other video on the rebuild, was a huge task. I do miss my Patrol 😪
I'm no mechanic, and I'm not very well educated with engines. Could you advise me which would be best to buy, for a auto to manual conversion... really like the thick engine sound...would love to have on my patrol

Hi Craig. I am about to get Brunswick diesel to complete my upgrade on my GU with the 6.5 Optimizer. What would you suggest i get them to do while in there to save me doing it latter? Like the 4" exhaust etc.
Hi Paul, a fluid dampner would be good if they would fit one for you. 4" exhaust is not really necessary to be honest. The trouble with the brunswick 3" exhaust is the bends are not mandrel. The Carter Black 15psi lift pump is a great addition to.

If you run the air dog or similar fuel delivery systems you get enough fuel flow that the PMD will not go bad mounted on the IP. The turbo definitely neds to be upgraded and the Harmonic balancer definitely needs to be replaced, I snapped a crank when my Harmonic balancer broke apart. These engines are good if you tinker with them. They are not work horses like a Cummins but are good for little 4X4's and jeeps plus get great milage.
