I really don't see how "taxi engine" is anything but a compliment. Yeah shit, my engine can run for a million kilometres before needing a rebuild, poor me.

Mass-Debate... I lol’d

All great engines, barra is the new torque king , you can see how they both get very defensive when the barra is mentioned, its called fear.

Am I only one who see Beavis and Butt-Head here ?

As a built GTR owner, have to say the Barra is one of the best motors, they would be there battling for 1st place. They may be a little heavier, but they produce the torque to back it up. 1000nm of torque with a boost and tune on 98 on a FG motor. My GTR is still sitting at around 650-700nm. Barra produces more torque than most V8s today, they are just super responsive motors. Cant go wrong with them, lots of Americans are starting to import these motors from Aus and swap them into Mustangs.

Barra, has proved itself across the board, no other 6 has, ever!

All the shit-talk about Barra’s, but at the end of the day, the XR6 Turbo is ALWAYS gonna have the torque and power to win a street race The rice cookers are great, but good luck on the straight 🖕🏼💀

This video was brilliant! Definitely want this to be a series! As an American I love learning how you power mad Aussie maniacs think/do things. Edit: Can you do more of these for other engines, power-adders, fuel types ect? This was so entertaining! Keep the same 3 blokes too (well maybe add some Tuning Fork)

i feel like you guys should have some beers up there with ya, make if feel more like a kick back conversation

Barras are by far the most reliable and cheapest

This was really well paced. I'd love to see more of these

Barra engine is one of the most underrated engines there is you guys bag it as much as you want but means they will still be around for the ones that want them. The amount of Barra swaps happening now prove that they are being used for motorsport and street now as well. They are proven in drag and in drifting. The benefit of the barra is it's solid and they have simple bolt ons and can make great power and still be reliable.

I have a 1jz and a 1hz but my dream 6cyl is a common rail Cummins!

Christian the JZ fanboy lost the debate and a good deal of my respect when he said "Only slow cars go around corners." If reliability were the only criteria, the JZ might edge out the RB, but these engines were not designed around straight line drag cars. Toyota has never made a chassis anywhere near the GT-R's capability. For it's time, the GT-R was a true exotic lightweight supercar and it's racing success is legendary. Even with it's AWD and HICCA rear steering systems the 1994 R32 was 300lb lighter than the Supra. Sure, having a low revving cast iron block may improve it's ability to handle more power, but a heavy low tech engine doesn't belong in a winning GT car. In all reality, peak HP is a poor measure of an engines actual performance. Where the engine starts making torque and power, how flat the power curve is, and how long it continues to make power all ads up how fast a car is in a given application. Another massive factor is the power to weight ratio. The 840 horse Challenger SRT Demon may pull a 9.7 quarter-mile on 100 octane race gas and drag slicks, but 600+ HP R34 GT-Gs are doing that on pump gas and street tires. Then beat the snot out of a BMW M3 on a road course. All that on a 20 year old platform.

Great interview and response from both guys 💪🏾

Two jdm fan boys too biased to see how good the Barra really is 💪🏼💪🏼

#barratheworld

You have for gotten the Atlas I6 4.2/3.5/2.8 and the AMC/Jeep 4.0/4.2 I6 (they are heavily raced in ACTC at 9000 rpm)

Great discussion!!! And awesome video!!!

These guys really are Master-Debaters! Good content....

I was a big RB and I adore the 2J but I want the Barra in a mustang :-)

I run a built Toyota 1GRFE V6 that is boosted and managed by a Haltech elite 2500. Nice little combo for the street...

Oooooo I love a good mass debate!!!!

For old school low tech I enjoyed my old M20 in my E30. Tapped a fair bit and wasn’t massively fast, but had a good note to it and took a beating.

Personally, my favorite inline-six is the Cummins 6BT. A diesel! Couple of reasons. Strong as hell, easy as pie to modify, simple, reliable, durable, massive stock power potential, stratospheric fully-built potential. Only downside is the weight, but the amount of torque they can develop can easily overcome the weight penalty on the straightaways. You don't stick Cummins engines in handlers, but to be honest, with any engine pushing 1K HP; you're not building a handler. There's just too much power. I do love me some RB, Barra and JZ action, but they're the obvious answers to any inline-six debate. I wanted to do something different.

I love both the JZ and RB series of engines, both very iconic and beloved, but let's be honest here, out of the two, the JZ engines are far more reliable and produce much more power than its RB counterparts.

being a mark 3 supra fan and owning multiple i was already thinking the 7m was the worst inline 6. I literally laughed when you guys said it was the worst haha. great stuff haltech and keep stuff like this coming.

L28 carby at 9000rpm, not fast but the sound 👌

There are many cool 6-bangers out there in many configurations; I like them all in their own way! One 6cyl engine (and car) that I'd really like to experience/own is the Audi RS4 B5 wagon, with the AZR 2.7 V6 30v Bi-Turbo engine. In the case of RB, JZ or Barra (to stay on the L6 topic) ; I'm not in any fan-camp - so manufacturer / model/type/configuration etc doesn't really matter. However; Reliability & engine+car character would be the biggest decision-factors for me, if money wasn't an issue (sad but true: money is an issue for me, but I'm working like a devil to solve that bit ;) ) Thanks for the video Haltech! Informative and entertaining! :D

0:00-21:49 all in all, Barra wins. Thank me later

Yes! You didn't forget the Hemi six! Love the noise they make 😀😀

Even though it's a V , the VW VR6 12v is a tank that can make gobs of power turbocharged. I own both Vr612v boosted, and N55. The 12v boosted is by far the best sounding 6. Done right, sounds just like a monster v8. Lots of vr6 are pushing 600hp on stock blocks with just bolts, and rod caps.

There are a lot more good inline 6s than just those three.. like the M50, m52, m54, s50, S54, S38, m104, om606, TB48, N54, B6304 and probably much more.

2JZ all the way for me. Have you guys done one of these on 4 cylinder engines? if not you should.

The Ford Barra may be Large but damn she's a lovely inline 6.

Mercedes m104 and bmw m50. Those are the unknown jewels.

7mgte can be a good engine. It got a bad rep because Toyota screwed up the head bolt specifications so they blew head gaskets. But 7mgte with arp head studs and eagle racing parts could produce very respectable power. I own a 7m, the day I got it I took it apart and rebuilt it 😂 been running pretty good ever since 😁

People are gonna look back at this in another 10-15 years and laugh, the Barra will be as prolific and as sought after as the 2J.

I just bought a 1JZ for a swap into my HR Holden. This video just gave me goosebumps!

18:33 “and if it sounds like a v6, I don’t like it” SMASH CUT MANG MANG MANG MANG That fucking got me

265 Hemi

i really think the om606 deserves a spot on the list, a diesel engine very comparable to its petrol counterpart, they sound amazing

I think they're all good, use which ever fits in your car easiest and you have availability for, cubes definitely help no doubt

The one guy said that Barra is “vanilla like a LS”, as if that’s a bad thing? Being that I’m in the US, 2Js and RBs are rare (stupid expensive) and Barras are nonexistent. If I’m swapping engines into a car, it’s gonna be a LS. People can complain about “cookie cutter” and “everyone does it”, but there’s a reason. It makes reliable, durable power while being readily available, cheap, and have massive aftermarket support. A small cam can bump power 50-100hp. Adding boost turns them into a monster.

To me, 1jz is the best sounding. 🎶

You only have to read about the RB to know that it has its weak points compared to the 2/1JZ engines, AND this is coming from a GTR/RB fanatic! Doesn’t mean I’d rather own a Supra or even want a 2JZ in my car. I’ll always love my RB, some people will say it’s junk but I’d say it has charisma 👍😊

@7:50ish. There's more aftermarket parts available for an RB... Because they need them. Gold. Comedy gold.

Do a 4 cylinder debate next

How about Mercedes M103 ( 12 valve from 80's / early 90's ) and M104 ( 24 valve all through the 90's ) ? This seems to be a popular engine in Euro countries and somewhat in the US. Are there many Mercedes in AU?

RB series is my favorite straight 6

I like the EZs from subaru. Compact design, 5v per cylinder. Main issue is they need a lot of work and parts to make good power reliably and the after market just isnt there yet.

I love the way he says mass debate

I do love my rb25 combined with the gt3076r turbo tho...

Subaru EZ30D"R" 245hp 290nm flat six non-Porsche therefore cheap with Porsche designed valve train. Just don't try to get more power without boost, or expect much more with it, but it's a great engine, timing chain lasts forever, smooth, powerful and did I say smooth? So smooth you wouldn't hear it running if it weren't for the timing chain whine, and Subarus have gearbox dipsticks so they win at life.

not going to say its a good motor but it may help others running one as am i - the 7m is missing a water gallery passage from the block to the head on the exhaust side of the block it forms a hot spot on the block and cooks the head gasket and head above it normally cly 5 and 2 on the outward sides closest to front and back easily fixed by drilling into the head gasket and block 3mm hole to copy the intake side of the block (ive done similar with 7age conversions and its been 100% fine) , the head has 100% compatibility with this mod as it is meant to pass water there!! as standard the cooled head and the hot block under it unable to pass water just creates a pretty bad temperature difference ive got a warped block here and melted expanded head gasket in this exact location on my old engine to prove it (also the GE cranks are mostly 6mge cranks and not really balanced well compared to any 7mge or gte stamped crank so if u lookign for a good 7m start there with one thats running the 7m type crank as 6m had bad harmonic my last 6m cranked one ate the bores out)

Good conversation. Im a driver of a Barra Turbo, but like all flat 6's.

Never mind the lot of those, TB48 all the way!!

one honourable mention i think is VW's VR6 (which is technically not a V6) particularly the R32 engine. Gotta be one of the greatest sounding NA 6 cylinders. no idea how they go in terms of power/reliability, but have seen some turbo'd examples, so i guess that's something.

I'd guess a 2JZ style block (without its oil pump seal popping out all the time) just with RB bore-spacing and a RB head... But I'm a Volvo B6284 guy, so...

There are some great v6s out there if you want a v6 with good sound the es9j4 from a peugeot 406 is a good one almost no aftermarket support but make a about up to 390 to 400 stock if you change injectors, fuel pump and retune, only problem is they were used mianly in front wheel drive applications for reference it is the same engine used in the clio v6 and peugeot early 2000s formula series cars if im not mistaken. and a diesel straight six td42 and a petrol bmw straight six s55 and the original gtr engine are also pretty good.

Completely new to this series, quite enjoyed it though. What are the guys opinions on the Subaru EZ30 engine? Neither a straight or V 6. :)

The RBs can kick rocks. They were barely reliable stock. The only reason ppl liked them so much is because they were in GTRs. The JZ and the Barra are better because they can the take extra power on stock components. And as far as the barra beinga taxi engine, thats the greatest complement you can give an engine. Keep your webo fanboy RBs and JZs. Give me a good old Barra. And this is from a Yank.

Inline 6’s are legendary but some v6’s still can make so power I own z32 3.0 litre vg30dett and I wish it had a RB26 but built the motor and with the haltech runs low 600whp the platinum pro gave it an update in drivability best mod besides 6 piston brembos. In North America my first fast car was my 1986 Buick Grand national with a 3.8 s.f.i turbo intercooler. That car made power but that’s power from the late 80’s. Australia was spoiled with all those killer JDM cars.

Best mass debaters I've ever seen

I wish Subaru learnt from their past builds and improved on things instead of making the ej25 worse in so many ways than the EJ20

epic mustache guy just doesn't have the same ring to it :( love the table flip tho!!!

Let's assume all things are equal. And the Barra was as old as the others. And the same dollars had been spent on r&d. And the same development as in billet blocks etc. From a factory new standpoint, From a cubic inch standpoint. From a completely non bias standpoint..

Prettiest 6 is either the Alfa V6 or the BME inline from the E24 635CSi/M1. Nostalgia for me is the Jag XK.

i like all 3 of these motors but im a bogan so its barra for me, tho i agree with pretty much the whole argument

If you haven't heard a GTV6 Busso, you are missing out on perhaps the best exhaust note from a sub 8 cylinder engine

First of all: All of the engines are reliable, and I have racing spec sheets that data back to the 1980's on various engines used from various vehicle manufacturers. And you can't say that the RB doesn't make big power or isn't reliable especially since it has broken over 1000hp almost since it's inception (1990 march prototype one of the many Nissan options which had a tick over 1000hp. VG being another) the jz engines didn't make anywhere near that until the late 90s (nobody raced *jz as 3s and 4ag based Toyotas were the favorite) and the barra just recently became popular (10yrs) technology is so much better today. It's hard to really make an accurate comparison. Anything 700+hp will eat you $14k-$20k reliably regardless of make.

I've seen and even drove a fair share of liner sixes (Which I like to call them) and even knew a few guys who had amazing cars with liner sixes. The RB series of engine are nicer to hear and they're easier to work with with the huge amount of aftermarket parts and it looks the nicest of all liner sixes in the general market. JZs are the real indestructible engine from Japan. Aftermarket parts ain't lacking too but you don't have to do much in order to get crazy levels of horsepower from it and it would easily bolt on to many other cars like E36 M3s or E34 M5 or those Mercedes W124 and hoon it around like what many Arabs do. Meanwhile, the most underrated one would be the Barra. It could hold crazy levels of power like the JZ could and also sounds as nice as RBs and are also pretty easy to get across Australia and certain parts of New Zealand and also can be damn easy to work on. HOWEVER, same as it's easy to get in Aussie and NZ, it's totally non-existent outside of Australia and NZ coupled with close to 0 aftermarket support outside of these 2 place AND an superbly old design. The underdog would have to be a M54 from BMW. They make amazing sounds and can give decent horsepower if it just doesn't break down so easily by adding more power and the stupid Vanos system doesn't knock out.

What about the Mopar 4.0L straight six or the Cummins 5.9L?

1G-GTE! If you want to hear a sweet sounding engine listen to 1G at 9000rpm... if you can find one

I like all jz's and RB26 engines. The only thing with the RB26 is that there is not as many as the 1jz and 2jz engines out there. So for availability I choose the jz engine range.

Another materbate on 6 cylinder engines!

S38 old school king

What about the flat 6 that Porsche use . 500 hp naturally aspirated Porsche gt3?

@5:50 Sure is nice having a 2JZGTE short block manufactured and assembled by Toyota Japan in 2022

S20 I6 from the C10 Skyline GT-R. They sound amazing on-song.

Tb48t big power big torque sounds good

#BARRAGE

1st - being a taxi is a compliment means low maintenance high reliability. 2nd - Barra comes in a heavy car yes and the 2jz started in a Aristo which weighs the same as Falcon 3rd - The JZ series was developed by Yamaha 4th - The high powered JZs are Billett blocks of a yamaha design full of aftermarket parts. 5th - A 3.7 litre Barra block made 2200hp ATWs. No billet, no yamaha needed.

What about The Vr6 motors? 2.8L fairly stout and inline with degreed pistons?

WTF? , Barra will toast both of these boat anchors !!

The barra is never going to be as good at the track. That big capacity and resulting huge lump of low/midrange torque will toast your tyres, and good luck going quick after that. The engine is also physically huge and still iron block, heaps of weight that is going to be both high up and forward of the front axles so whatever its in will handle like a bucket of snot. The barra is going to be a much loved engine by the kind of people who only ever do burnouts and compare dyno numbers. It will go competitively quick at the drag strip with enough development. But it's not going to make its mark on any kind of racing that involves corners, and that in my opinion is why it doesn't compare to the Japanese 6s. The JZ and the RB are still jack-of-all-trades weapons of choice decades after their development, and I don't see the barra ever having that kind of ubiquity in racing.

265 Hemi six, triple Webers, stage 3 cam. Now that is a nice noise maker!

Really with Ford brought those Bara I6 engines to North America would have been tons of interesting fun

mercedes-Benz OM606 3,0 liter diesel and BMW M50

Didn’t mention the 250 xflow

What I'd love to see, is not so much a versus, but a civilized talk between a RB and 1/2JZ fan against a small block/ big block V8 fan or LS/ Hemi fan ect. Just to see what they actually say and their comparisons and data and knowledge and just to see car fans actually getting along even though being from completely different worlds in motoring. I've never said this before, but thumbs up if you'd like to see that kind of conversation? Second issue I'd like to address, the whole Barra situation, yes, they're available, but for how long? No one makes them no more. People from USA are interested and are buying them, they're big in dimension and heavy, I mean yes, they make decent power, they are reliable to an extent, but the issues are yet to come in terms of availability, and over here, I mean I know you can get them from the wreckers and so forth, but the aftermarket parts aren't really out there compared to the RB or JZ series, and they aren't being produced any more. Then there is the price factor of said aftermarket parts. As the RB guy said, there isn't much desirability with them, you could be in a taxi, or just some Falcon, and be like eh just another motor in a car, but if your in a R-3X Skyline or Supra/ Chaser etc there is stigma to it. Also... in my opinion, the Barra is kind of ugly.. in a way. I do adore all three of the motors, but the Barra hasn't been in the game long enough and it won't be due to unfortunate circumstances.

What do I do if I like both jz and rb? Have a stock r32 gtst, stock intake stock exhaust, even with the stock exhaust sounds good straight through factory muffler has great burble at idle, also have an aristo, daily’d it for years, sounds great, now amidst a big build, noise...jz still wins for me, but it’s close, the 20 sounds great. The Nissan has its quirks mechanically, jz has less in my experiences. Jdm>adm

RB!

Aussies probably don't even know the glory of the B6304 & B6324 sixes from Volvo, amazing engines

Power and Noise 2JZ > Barra Price and Availability Barra>2JZ Engine Swap ability 2JZ>Barra my Personal Favorite 2JZ What I would go with on a Budget Barra (If I can't get an LS)

I don't mind the sound of the Nissan VQ-35/37 engines.

you just can’t kill a JZ motor though that’s the thing

the 7mgte is underrated

Definitely a couple of mass debaters.

You forgot the MAGNA 6G72-74 and Mitsubishi 380 6G75 , I run a turbo’d 6g74 love it
