Sam is responsible for GU diffs in SEQLD being hard to come by and costly now

Mazda 3 2.5 litre swap is where the performance gains are.

I love my LBZ.. But here's what I found out. 1- Massive weight difference. Don't be lauching too high you'll break a lot of stuff, and you really feel it in deep mud and winching. 2- Its definatly not cheaper to run. Uses 10 liters of oil instead of 5, oil filter is 3x the cost ( GM parts comparrison) plus a $100 fuel filter if your running factory. But you'll need to add 2 more because you should run a lift pump for the fuel for any deisel truck. When they do break parts are way more than an LS and a lot needs to come off to get to the motor. A set of injectors cost what I pay for a complete LS...Up side... Off road low range incredible fuel milage with tons of torque on demand. Towing is effortless and more realiable especially in deep water. I would reccommend ARP head studds and fuel rail race plug. No more than a 500HP tune which will get you into the 700-775 fp of torque. I'd look into a DSP switch( 5 different tunes) Check out Duramax Tuner on KZfaq for good info. Get some sort of lift pump (FASS).. If your using the Allison trans, definitly a better torque converter and slight buld. Same with the transfer case. It will need a pump rub kit, and upgraded input/ out put bearings.. After all that I still prefer the Dmax for any long distance drives !00% Great Video Thx!

200k brother you’re a beast !!! So awesome man, been watching since 15k subscribers well deserved 😎🤙🏼🤙🏼🤙🏼

I'm glad you went to a duramax for your own reasons I just spent a heap of money rebuilding my td42t and yes the turbo ones are built for boost over the na ones but you compare them to the 1hz and 1hd the td42 need heaps of work my td42t is 230hp 730nm and for it to stay reliable its had heaps spent on it but I wish I went tb48 or a barra instead cause it wouldn't be as expensive

Mint build Sam the whole series has been good

Love my L5P Duramax, pulls like a mo fo. Watched you do the original build when you were just a backyard whipper snapper with 12 subscribers, happy to see that you have come around to the Duramax!

good video ! well said ! great video and audio quality!!

Have loved your channel and your never give up attitude to your builds, keep it up 👍. I’m wanting to do a duramax conversion into my 105 1hz. Not sure how practical

Always remember Torque is in relation to Power! as of RPM. If you lower the RPM in which an engine produces power, Torque will climb and the other way around. So the reason why a 6BT produces so much torque is because it revs just to 2-3 k rpm. So in an low reving application, like for orr road or touring an engine with low down tq is nice. Here in Germany it can be completely different: When I drive to work I will go 100 mph, usually when partly free, or 150 mph when free. So max torque @3000 PRM is not so usefull, because my Z3 is @ 3500 RPM @ 120k/h (75mph).

Mate.. I gotta say.. You get it done and you speak sense. Good Work

Really cool build, would be cool to see the old ls in a race buggy or Trophy truck

done 30000km with a LSA and trans and had no problem other than an alternator. left it stock with 400HP. so far so good. hope you can find someone that can build Allison tran's over here reliably. i couldnt, ended up having to get one built in the US. but that was 10 years ago.

You mentioned the 1HD-FTE but what about the 4.5 V8 Toyota engine?

I think that it's not so much that diesel makes more torque (though it usually does on paper) but that the low rev torque is massively more useful for what you're doing with it. Power is only torque multiplied by revs after all and who wants a 4wd that has to be right up in the revs to do well?

Great choice. Your smart at avoiding the powerstroke because they are the least reliable of all the American diesels. That cummins that you drove I believe was the old 5.9. The newest 6.7 is smooth and quiet for a diesel. I love my 6.6 duramax.

That LS sound tho...

I wanna know what f but can cram a powder stroke into a au falcon Or I could do a ford territory diesel motor

only question is how can you say the duramax is so much more reliable for only having it put in recently compared to 3 years or so of experience with the LS, i guess the real test will happen over time.

G'day Sam. How did u get around the starter motor and diff clearance issues. My front diff keeps hitting the starter motor.

Hey, just wondering about all the accessories, gearboxes and belts that have been failing on the LS motor, wouldn't that be because of torque ? I'm not an expert, just a thought, I'd be glad to learn.

what are your views in the 1uzfe, doing a conversion on my ln166 hilux

Great info mate but did you air down the tires? 🤔

Good job you didn't go with a powerstroke! Deboss garage does some great videos on various diesels.

congrats on the 200K subs

I paused to see the "way too hot intake temps", 28 degrees, am I missing something? I can reach those intake temps on a stock 4 cylinder engine when idling around on a parking lot.

Great video mate

Awesome Stuff ! If your conversion was 40k how much would it be for drive in drive out

Not to mention the duramax is a very quiet running engine and not much vibration at idle for a diesel.. and they always start up great in cold weather!!

Cause every Tom, Dick & Harry has done a Barra hey Sam lol lol Would you tackle another Duramax conversion one day mate, maybe into a Gu Wagon, I'd love to get one done some day buddy 🤞🤞 Hope the new motor serves you well and keep up the fantastic work mate 👌👌 Ps. Glad your keeping the LS & what's the Chev you have plz Sam ?? 67 Impala wagon ??

Done well mate love it. Would love to convert mine aswell one day.

Still reackon its cheaper to go with an old 7.3l powerstroke f250. They are a few in aussie. Seem to me to be easier and cheaper to just iron out the problems of an old 250 than a big engine swap

Thanks for the advice

what are your thoughts on a barra? please explain

Great explanation. Best engine choice that could have been made. Was there much involved with engineering.

What about the 1VD engine? That's a V8, reliable smooth diesel relatively compact, tons of torque, very efficient compared to the Duramax and much cheaper, available everywhere in Australia. And with the 70 series single turbo version very simple. And power and torque add ups is very easy. Just some good for thought.

Bloody love the duramax setup, but it would have been cool to have done a 1hd-fte with a decent turbo etc

Very interesting I have the L.S.3 motor In my 80 series I've only had to change My transfer case in 7 years

Why did you leave out the barra? It's better than most of the engines listed and more reliable.

I remember back in the shed days when you first put the ls in feels like so long ago

should of gone a 6BT mate... Nah love it bro the Duramax will serve you well

Which Cummins motor were you talking about in this video.

Barra going in the wags for sureee

LS no good for towing?? The 6.2 came in a 3000kg pickup, rated to tow 5500kg, without a blower. The newer LT version is rated even higher. Is the Duramax better for towing, sure, but not enough to justify the 200kg extra on the front axle.

Forgot about the trusty 4jj1 4cyl but has potential without a doubt

What series duramax is it.

My brother had a td4.2 in his patrol, the swap to barra after it died meant no change in fuel consumption but 1 piece of driveline per 5000km ish and that's NA... Since the conversion it's now the most reliable part of the car. I think you'd be going too usual and ordinary to go a barra. Cheers for the video

Did you think about putting a y62 v8 engine in the patrol

A little bit of misinformation about the Cummins. Only the pre-2003 engines and the p-pump mechanical engines are loud and rattley, not all of them. The common rail engines released around the same time as the lbz and the later 6.7 engines are much quieter and smoother and are on par the the duramax and arguably are slightly cheaper to extract power put of. Love the build though mate the duramax suits your rig perfectly 👌

I know it’s not v8 but did you consider a 6bt?

good job mate

Would it be possible to explain what is actually involved to one do the swap and secondly, what is involved engineering wise to get this road registered in the various States around Australia.

Did you consider a 4jj?

Not just the Barra you forgot 6.5 chev the old Brunswick conversion 😉😂😂 all tho glad you did the duramax conversion getting too be more common conversion but still not a heap out there

What’s the cost since you bought the patrol as a cab and chassis donor? Let’s not torque about it.

You didn't like the Cummins but the one you showed was a 6bt, I had a 6.7 (same as current ram3500) in an 84 f250 and it was a great conversion, way better than the 6bt... go for a spin in one to compare.

I was a bit confused when I saw Sam driving a wagon in the first chasing lines series. Though I haven't watched the LS swap series. But I'm thinking the wagon got chopped. Edit: Sam has been having the experiences of somone who's done a crazy engine swap. But it was good fun while it lasted.

What about the vdj?

That sounds awesome

Nice mate

I wish we had only $2 a litre for 98 😭 pushing over $3 and diesel is about $2.15 Can’t wait to see the duramax tho! Love the vibes

If you want something with horsepower for playing around the LS is an excellent choice, but as you australians like to travel in a vehicle with trailer that can have a combined weight of 6 tons easily the duramax 6.6 is a much better choice

Modifications and Reliability rarely go hand in hand. You start messing around and you lose the long term testing that comes from a factory car.

One think you miss. How much Duramax is hevier than LS?

I’m suss your blown 6l ls only had 600nm. Would have been 800+ for sure. Stock ls3 with a tune will make 600nm.

What about the vdj mate?

The other great thing about the duramax that he didn't even mention is the Alison automatic

Not sure why you need so much power for a 4wd that was never designed for it.. hence broken diffs and gearboxes etc but each to their own.. Something like 150-200hp and near 600nm of torque at the wheels is plenty for a GU. The TD seems to get a bit of flack for being a kettle but it's about the same amount of repetitious nonsense as those people that say land cruisers are reliable lol. I've seen a lot of TD42's north of 800 thou km with unopened engines still going strong.. If you're sensible with mods and servicing it'll last a long time.. But if you're chasing reliable big power north of 250hp I agree with you that it ain't the engine to be using.

Cummings isv5 from the titan, 5 liter v8. sounds like a duramax too.

Nice job I have a lbz too

Love your work fuck the haters, too many people talking shit....

Glad you didnt go with the Barra . yeah makes power etc but thirsty as . probably not good for towing either

Glad I watched till the end, Barra comment👌

The Patrol is a 4WD , not a race car. TD42’s do just fine and don’t over heat if you keep the afr’s in check and tuned properly with 15/20 psi boost. If you need more torque and power than that then sure do a conversion like this one or buy a RAM or Chevy 2500 diesel heavy duty. If you don’t mine getting somewhere a little bit slower then use a 4WD as it was built out of the factory. They were never designed to go fast.

Go ahead mate, go ahead,

5:08 Eddie Hall haha

So are you going to do diesel for the 80

Sam I think you should have explained the power and torque thing a bit better for those that don't understand. Half your viewers probably think power is measured on the dyno which is obviously not the case. The difference between the two engines is not the power, just the torque. That difference comes from the chemical differences between the fuel and the induction. Then if you explain how power is calculated it becomes obvious why you would choose a disel for this application. For those that don't know, power(kW) = torque(Nm) x RPM/9.5488. So the faster you spin an engine (petrol) the more power it makes because of higher RPM. A better comparison between the two engines would be to compare their torque curves and where in the rev range they make peak torque.

Always good to change the heart

Not quite sure why you're hating the barra I totally agree that duramax is better. but when you did the comparison against the LS v the barra a few months to go, the barra seemed to win all the important stuff.

Wait what about the 1vd, dissing the 70 now?

Your also forgetting maintenance and parts availability - to make a diesel last it needs to be serviced every 5000km so there goes your fuel savings. Parts a standard Ish LS alternator etc will be available at pretty much every super cheap good luck with that for a duramax around aus. As for driveline braking that’s partly the joys of a heavy rig with a manual with power. If you stuck with a 6l90e you would of more than halved the driveline headaches.

Buikding a Trophy truck. guessing that's what the ls will end up landing in 🤔🤔

I reckon you should have a crack at a TDV6 Disco motor coversion .

Come On 200k🎆🎆🎆

Sounds like u are trying to convince yourself you made the right decision, #LSTHEWORLD

Barra? If torque was an issue with the Ls… the barra won’t cut it, ok if your running the quarter in a car half the weight, but having to keep it spooled while you pull hills towing? gross. . .If that was the case another 1fzfe with a super charger would have been a better choice, particularly if it was the 5.0 stroker. At the end of the day when torque is needed, pound for pound the diesel will deliver. Not my cup of tea, but when there is a purpose ( in this case pulling weight) it’s the right tool for the job. But it does not excite me anywhere near as much as the cruiser.

What’s the weight difference between the LS and Duramax? Great build as always dude 👍🏻👍🏻

Side-graphics are classic

Sooooo you should have done the duramax in the beginning 😂😜

💪

OM606 for the win

It was really down to power stroke or duramax both are great, but the Cummins is to big they are so long

blown LS not enough power for a heavy rig. What about.... every single SUV with an LS in it over in the USA. stock american cars are heavier than a little nissan ute :P

barra the og wagon

Barra-petrol and would have the same issues as the LS after time. haha

Diesel are way more complicated. But they are bigger heavier engines they can take more punishment.

should have gone with the ford Intech

everytime i google 'what is the difference between power and torque' i understand and then immediately forget it.

Diesel power!
