I really enjoy the no fuss approach Al takes to these videos. SOO many cowboys on the net talking rubbish. Al has wiped the floor with them in such a modest professional way. Thank for everything you do Al. I hope you continue along and provide more great info in the future!!! nice work on the edit to Woodrigos

15:30 "Nowadays everyone hates smoke, which has changed from last week." Subtle and timely remark there, well said.

Projects are always bad financial decisions but it's what we like and it makes us happy

This is a really good 'build summary' presentation. I'd like to see something like this with any build.

When Master Turbo Yoda gives you advice about engine swaps, you just sit down and listen! 😎

Honestly informal episodes with Al just talking about stuff are some of the best episodes.

moral of the story everything is expensive hence why we're all on here watching people do conversions

Absolutely love the project follow-up. I will almost definitely never even own a patrol let alone do an engine conversion on one, but I still find this background knowledge and perspective fascinating.

Nice to see honest opinions from someone about there own build. Its too easy to just pretend what you did is all spot on and perfect. 4JJ1 would be a good choice in the Diesel world but i reckon a Barra with around 380 RWKW would be tough to beat and the 25 odd grand of fuel you could buy with the savings would go a long way.

'You're probably getting sick of me talking' NOT AT ALL I'm not a mechanic, have never and probably will never pull a car apart and I could listen to Al explain stuff all day. Passionate no nonsense approach makes every thing Al says hold weight. Always learning from you Al, Cheers

I enjoyed watching the whole build from the Deboss engine build all the way the finished product.

One of the BMW M57 varients, hard to beat price wise. Tremendous tunability and incredibly strong. Can get them from UK wreckers for pennies. That or an OM606.

So Ummm… I see woody being denied a lemon squash in the near future. Well worth it though. Great insight, thanks Al and Woody.

Not even remotely close to getting sick of hearing you talk about what you know. When someone knows what they are taking about & is willing to share their experience based knowledge, it’s nothing but interesting & enjoyable to listen to. Keep on doing what you’ve been doing. I for one appreciate learning from you. Thanks!!

GVM and GCM became a problem when the insurance companies started weighing everything that fell out of your 4x4 onto the road after you rolled it with your 87ft van on the back to deny a claim.

People here in Europe are using the BMW M57 engine. It’s one of the best BMW’s engine ever made and some people also instal the 6 speed gearbox from BMW . It’s a fantastic upgrade for the Patrol but unfortunately it is not legal in every EU countries to do this conversion.

These are some of best videos with real world costs from experts ie experienced people. Reminds me of my Series 3 Land Rover and the Holden 186 conversion. It was an Aussie thing to do. Thanks Al & Woody

I'm currently doing a TB45 to TD42 conversion and keeping the RE4 auto like you did with the red Patrol. Your videos have been an absolute wealth of knowledge and I really appreciate how much detail you go into. I am making it hard for myself by not manualising the auto like you did, but also keeping the ECU and TCM and not going the easy but expensive route of getting a kit from Wholesale Auto or wherever. Love your work guys, keep it up!

Google M57 bmw patrol. they seem to go great. thanks for sharing your thoughts on this conversion, especially since you have done a couple of different ones. i have had the a duramax also and now a LSA . they are both great in their own right but very happy with the LSA now and prefer it. the ease to work on it, to get parts locally and the milage is no worse than a 4.5 or 4.8 from Nissan and instant power it makes, makes it a very enjoyable 4 wheeler.

I can say with 100% certainty I will never be doing this conversion, but I love the sharing of knowledge! Could listen for days.

Child hood memories of my friend broadsiding me in a mud pit. Four wheels spinning and the sound of a duel exhausts 350 chevy roaring, just a magic moment. My little LC torana was buried.

Awesome advice Al. Lots of things to think about when doing these conversions. Also plenty of time and money!

Was looking into this a few years back. Went with a 1HDT conversion for my 105 series instead due to availability, ease and cost. Was pretty happy with the result, made 190hp 700nm on 35s and never gets hot.

Umm uh.... best ending so far, you're killing it Woody!!!!

For us Europeans, the 3,2l V6 or the 4l V8 Mercedes engines might be good options for a torque needy application like this. Thanks for the extra knowledge sharing, guys! The hard bit is making it all work long term and refining it.

A lot of BMW M57 are swapped in Europe, although not done legally as in Australia. Some shops in Iceland do OM648 as it must be easier to find and more modern than the OM606. Thanks again, very interesting. I've been watching your channel since the double unicorn swap and it's still one of my favorite, even after 3-4 years. Keep it coming !!!

ive seen lots of bmw m57 swaps into patrols. hell of an engine to put into one

people on the facebook pages keeps saying 6bt cost the same as a td42 ( to swap from a zd30) and i just laught, now i can link them this video, cheers guys awesome vid!

If the Mercedes diesels seem interesting to you, be sure to also check out the BMW diesels. The M67 is interesting, but not that common, while M57/N57/B57 are very well supported, though they obviously sacrifice some displacement.

Nice old school video. No soy face, no screaming, no in video adds, no try hard. All day long mate. 10/10.

I’ll probably cop it here, I’ve had many cruisers and patrols. I’d love to have a S4+ patrol with a 5speed 1hdfte.

Tune your AFC to not give as much fuel before boost pressure comes up & you'll cut out that low end smoke & can actually get the turbo to spool up faster. You might need to change the spring or even to several springs within it. If you know an idea of your various boost pressures you can bench test the AFC foot travel accordingly to help speed up parts choices & adjustments.

Come on Alan, go full madlad and install an exhaust brake 😁 If the Karens thought it was loud before...

Been a great build to watch.... Credit to you. Another common engine is a BMW M57 3.0 TI, 6 Speed ZF Auto, All Software Controlled..... Great Economy, Heaps of Torque n Power and Whisper quite... Been done for a decade in Europe

Woody- you could set Al's umm's at the end of the video to a techno rhythm and sell a skid factory original composition 🤣

Who would thumbs down this video? Seriously. Al, great TED talk. Super informative. Thanks a lot guys. Look forward to the next one.

Great vlog as all are from you guys! If you have another Patrol available consider doing a OM606 or the later model OM648 (common rail). But if the goal is to go bush on remote areas I would choose the OM606 any day. Stay Safe !

50K Australian. Forget about that you built it. Are there not new vehicles with similar capabilities available? I get the built not bought. As stated. Get out a pen and paper. Very informative. Glad to see y'all back in the shed. Thanks.

I put a p pump 5.9 into my 79 ford, kept the dodge running gear but built it up. Can confirm the noise. Couple tricks are oil pan wraps, pushrod cover and valve cover wraps, where most the noise resonates. Made a good difference in mine.

This is now my favourite video on here. Normally blank out the talking but this was perfectly done. Well done

Another great episode. I doubt anyone is sick of hearing your wisdom Al, its time to sit down and learn from the master. Been watching since you were on MCM2, given me the confidence to do my own Turbo V8 conversion in my 4x4 which is going well.

I own a 105 and not a patrol but really enjoyed listening to what you had to say

As usual Al, it's a pleasure to hear your no nonsense, zero BS thoughts on the subject.

Excellent presentation Al. Regarding noise. I have a 6BTA in mine, I halved the noise by surrounding it with acoustic foam. It does not block the noise it absorbs it. It looks like egg carton, dark grey foam. Very lite as well. I think it would work on (under) the bonnet. Buy from foam supplier. Mark.

Good one Al, massive cost though. Perhaps for the next conversion a BMW M57 diesel could be looked at, nice and modern, plenty of power available with upgrades, plenty of donor engines or vehicles around as well.

Yup, modifying a vehicle in Australia isn't cheap especially if you get it engineered too. Depending on what state it can be really wallet unfriendly. The UK and USA are certainly cheaper to do modifications but all those that say they can do a swap for under $5K are thinking they're still in the 90's 😉 I love how you sit there and calmly tell people the way it really is. Dispelling the internet hype is always so much fun to watch 👍

Hi Al and Woody, great summary of the conversion, and like has been said would be great with every build you guys do. Take a look at the BMW M57 engine. Readily available here, cheap, strong straight 6 3.0l common rail. Very similar to the OM606. There is an English company that sell stand alone cracked ecu’s for not much so would make a great swap that other ozzys could copy as engines are available here. I think they run the same ZF auto as the Barra and adapters for these to patrol cases are available off the shelf so again, nothing too fancy. So cheap smooth revy power with modern common rail and matching auto. Wining combo maybe? Keep it up lads 👍

Just when i thought i could take on putting a thong slapper from a 79 in my 80, along come al n woody and hit me with a reality check 🤣 Great stuff guys and awsome info keep it up 🤘👍👌

Im very close to embarking on a 6BT > LR Defender swap and i watched this video to try and convince myself it was a bad idea. It had the opposite effect.

Some options I’d consider would be the Mercedes OM606, BMW M57, Toyota 4.5 1VD-FTV Baby duramax, the very well sorted Citroen 3.0L V6TT also used in NAVARA, Range Rover, BMW & gale banks does a version of it, to name a few engines I’d consider into my series 10 patrol,

As for the merc diesel- we just had one that ran well come through the shop with close to 950,000 miles on it. Driver said they’d done a tranny but the motor had never been cracked open. Was a sprinter van.

Amazingly honest review for someone who has just dropped 50K and god knows how many hours on the conversion. Thank you

Always good to hear Al talk about the engineering that goes into these projects. Watching a youtube video, you don't really get a feel of the cost of such conversions.. I mean, if there is all that custom fabrication, then it will get expensive if you are not doing the work yourself. And we also need to bear in mind, these things take time as well. It's not something that can get done in a week.. Probably takes months. The one take away from this is there is no BS coming from Al's mouth... well except for the part about Dodge Gearboxes not being good. LOL. I've heard about Cummins powered Ram 2500s getting over 500,000 kms with no issues. It all depends on the maintenance...

love the ep. very calm and straight forward and most of all informative. i'm more of a GO FASTER person than a bush basher but i still really enjoy all the builds regardless of what they are. every build i learn things and that's is one the the greatest reasons i keep coming back. when i finally get my project underway, i hope i remember one particular piece of advice from al's words of wisdom. use ya brain! i love the sound of a GM 8V92. would that fit in the next one? lol.

How good is an actual professional talking about modifying cars.... refreshing.

Go for it man!! 0M606, hope you hook up with a very well known English 606 geek!! The results will be epic!!!

Love it how AL just loves to do different conversions he really does teach us a lot of knowledge into idea of doing a conversion if I had the $ would love to do a duramax conversion on my patrol think it’s one of the best out there or buy a y62 I think

If you had the room for it, compounds quiet the motor down and reduce EGTs. Probably the best option for a single turbo would be a Super 9 hybrid from PDD, but they are not inexpensive (they build those themselves). Use all OEM mounts if you can, they quiet the engine down a lot. I did a swap of a OM617 into a car, it was incredibly loud until I found out that the transmission mount was contacting the frame. The noise dropped a tremendous amount after I made clearance for that mount.

Wow this is decades ahead of me. I’ve just gone the ol 6.5 diesel Na, I got it for $6000 from Brunswick diesel in WA, Was reasonably easy to install onto original 5 speed manual… I think I use less fuel than a Barra conversion would… in saying that my 6.5 is a slug 🐌 but I love her 😁

Hey Al here in the states commercial trucks use what is called a Jake Brake which use's engine compression to slow down Semi's here in the state's I am 69 years old and used to drive big Rigs back in the 70's and 80's and in a lot of high mountain driving so we always had Jake brake's on our trucks.

Thanks mate from Melbourne lockdown V6.0

I don't really like VGTs, but they have the added benefit of exhaust braking functionality. If you don't end up swapping to a VGT it's for sure worth installing an exhaust brake, especially if you doing any towing. Love the build 👌🏼 Perfect rig! I'm def biased tho have a 15L Cummins in my Kenworth

Popular over here in UK is the bmw m57 - plenty about and off-the-shelf harness & ecu's too.

I’d absolutely love to have a beer with Al and just fully talk max shit about cars and engines I love the way he thinks about things.

Thanks for the brutal honesty Al. I'm looking to buy a ZD30 patrol and swap it out for an LS.

EVERY build you do needs a run down like this. Good stuff.

I too was thinking om606, cause they do go quite well, but I can’t for the life of me find one, the common rail 613’s are much more available, but I don’t know what the ability to tune them are. The other option is the M57 or N57, I know nothing about these but I feel like aftermarket support in Australia might be a little more available. Once again I have no idea, but that’s what I’ve been toying with

After watching the build series and some deboss garage stuff, I thought about an Italian/eu version of those swaps. Here we have a few big diesel engine and those aren't cheap by any means, talking about vw v10 o v12 tdi or Mercedes v8. Like the Cummins we have some iveco engines out of light duty trucks, iveco tector 5.9 and 4.5 (6 and 4 cylinder) turbodiesel with common rail

Enjoyed the "debrief" video. Personally, I wouldn't use a Cummins in anything unless the vehicle is being used for towing or hauling. For an off-roader, I'd lean toward LS-something. But this was a fun project to watch and I'm glad we got to see it unfold. Methinks Al will be selling this Patrol to its next victim before too long.

i watched a video from AE co, they put a 4jj1 in a patrol as they can used a lot of the nissan gear, still expensive but if your not looking for huge power and reliability seemed to be a cheaper responsible option

I have a 12V F250, bought it built for less than half of the build price, so I know what it costs. You have a beautiful build there!

I ended up doing a td42 conversion, only coz it was cheap, found a cheap motor and only cost just under 6k to do, including motor

Before doing the ls3 and 6l80 swap in my Landcruiser I talked to a few guys that had done ls1 and ls2 swaps in there cars, they wanted more power and said the swap wasn’t that much better than the stock 4.5 petrol cruiser engine. I’m happy I went the ls3 and 6l80 but even doing all the work myself like Al also drawing on a number of other conversions it’s still expensive and takes hundreds of hours to do it right. I think these days in Australia the only semi budget friendly option would be a Barra turbo.

Awesome build summary! For a larger SUV like a Patrol I'd do a Ford 7.3L gas V8 if I could, pretty small and lightweight (for the capacity) with output of 430hp (320kw)/475lb-ft (645nm) on the crate engine. I drive the commercial variant of it in my work truck which is only 350hp/470lb-ft, it's fantastic for pulling around a 15-20,000lb (7-9,000kg) vehicle, has a load of low-end torque and gets decent fuel economy for what it is.

Figure torque is 2x the horsepower on any I6 diesel. I'd think an HX-35 would be fine, maybe an HX 35/40 hybrid. VP injection pump would go a long way towards tuning. No idea how prevalent that pump is over there though. I know guys praise the P7100 pump, but for tuning its like changing springs and weights in a distributor, then jets in the carburetor. Yeah it can be dialed in... but it takes a lot of trial and error. VP equipped engine can crank out 400hp no problem and not sacrifice bottom end response as long as the turbo is matched for the desired RPM range.

Noise? Daily drove an 04 Dodge for years, loved the sound it makes. As for what I'd swap, BMW N57. Not sure about in the Patrol (we don't get those over here) in terms of weight, but nice and light for a smaller off roader build.

Glad you touched on torque vs HP, most people hear low HP numbers for a diesel and think it is gutless, when the reality is it is far more powerful since it's torque output is far higher and usually at about half the RPM.

I would enjoy watching conversion with om606 or om613 even. Fits me better for daily driver.

Awesome info mate and I love your no bullshit approach. I'm in need of a conversion and a little stuck as to what to do with it. My truck is a 2001 single cab Mitsibushi Canter 4x4 that's been converted into a motorhome. It's way too underpowered as it is but it would definitely be cheaper for me to do a conversion rather than a complete rebuild!

Never owned a 4WD, only have a vague idea what a 'Cummins' is, why am I watching this? Other than it being entertaining and calming at the same time, I got nothing. Thanks for the content guys, the low-key delivery is fantastic.

Thanks for the general knowledge. It is surprising how much you do learn from content like this even if a full blown conversion is on the cards. Research Research Research Plan Plan Plan and repeat. Thanks Al for being honest and realisation. Enjoy sunny QLD

I just like the synthwave outtro music thanks woody 😉👍

Enjoyed this conversation, would like to see you do a common rail engine, and will be interesting to see how much less smoke it produces with a different turbo. Supprised when I visited Oz, I was in town walking and some one went past on boost in a landcruiser and the cloud of black shit was pointing straight at the pavement

I think a few people give up on the ZD's a little early, a lot of the problems stem from Nissan making them actually comply with Euro emissions standards with the re-circulation of gasses and theres a problem there when it essentially begins with one little thing, buggering up another little thing which in turn leads to the over-pressure from the turbo, clogged MAF, overfueling on some cylinders, leaning out in others, cats and dogs living together and explosions. So I completely understand if people throw them away! Actually fixing the ZD30 is possible, but its also requiring some diesel boys on the tools that know their stuff and a not inexpensive amount of big ticket items into the engine bay. Is that cheaper than a full engine swap? Yes, is it worth it to know you're more or less running it with a lot of aftermarket parts that need specialist techs to fix? That's really up to you as the owner and what you use the vehicle for and your access to those guys during the higher level servicing or go with the full swap to something with known reliability that can be fixed by lesser mortals.

Well, I'm glad I went down the Barra path for my 80. Less than $3000 so far including donor falcon and she's back on the road.

Love your work and the amount of effort you guys put in to bring us these videos! Thanks

Bought a new 2016 3.0 patrol and what really pissed me off, my 1992 TD42 patrol was nicer to drive and had way more power. So I bought a new GX land cruiser. Heaps of power and no conversion problems. Probably will not last as long as a TD42 patrol but it is nice to drive. You want power and nice to drive KEEP THE WEIGHT DOWN.

Great vid! Thanks for sharing all of your experiences with us Al.

In Europe the M57 BMW engine is a very popular swap for the patrol. I also have a friend to put one in a G class. The 4L Mercedes engine is is known to be a great engine but they don’t come cheap either. The M57 makes good power, cheap to buy, cheap to repair.

Love your videos mate...nice and relaxed and easy too watch.

I know this is a older post but Nissan uses a 5.0 v8 Cummins engine in the titan pickup in the US it might be a potential option rather than mix and matching components you could bag engine Trans and transfer case and put it in a patrol .

Thanks for your extensive knowledge mate. I learn something every time.

I hear ya Al, I've just put an LS1 4l60 into an old LN106 Hilux, the easy part was fitting the drive train into the vehicle, the big jobs are all the little jobs if that makes any sense.

7:53 me talking about my winky to the misses

I have never owned a diesel.....shows like this get me excited about getting one and start wrenching. Too bad not too many choices here in the USA, either a big truck or a TDI, ugh....euro stuff is too expensive to mess with

My favourite diesel conversion is the BMW m57 and m57n. 300hp and 900nm torque puts a smile on your face.

Couple quick questions about transmissions… Did you consider a G56 6 speed manual from a Ram truck or a 5 speed manual? The second would be did you consider an Allison? They make adapter plates for the Cummins. However, they still have to be built if you are increasing the power levels a whole lot. I do agree that a modern common rail 5.9L is quieter than a 24V or 12V P-Pump. I have a soft spot for the older mechanical fuel pump engines though. The “diesel clatter” just reminds me of farm tractors. You can tune a common rail to sound like a mechanical fuel pump engine.

This is by far my favourite channel. :)

Thanks for telling us about real cost of this project.
