@@jason.arthur.taylor OP isn't wrong.

As a BMW tech I can confirm, these engines are damn great. Just did a heat management module on a 440i today and a mechanical water pump on a G05 the day before. Super easy engines to work on, very reliable thus far, and capable of taking a lot of abuse.
@@davidrx795I think it’s safe to assume so. Only Toyota would come up with something like “hey let’s use this diesel engine, lower the compression, and add spark plugs” and only BMW would say “okay sure, and we’ll make it fast”

In stock form, the B58 is a gem of an engine. It's super smooth, has torque for days, revs quickly, and gets great fuel economy when not pushing it. Can't speak to the longevity of it, but in terms of operation, it's an absolutely brilliant motor.
Considering what it is made of, the tuneability and overall feedback of reliability so far, my predictions are that the engine will soon have a legendary reputation for reliability, up there with the M50/M52, N52, K series, 2JZ, Cummins 5.9 1.9tdi, Om606/OM617 and also the 3 cylinders found in the Geo metros/Suzuki swifts.
@@Josh-qm4rb Doubt that, it's a BMW lol. In the last two decades they have made some of the most unreliable cars on the road. I'm not just saying that for fun, the statistics don't suggest that they're shit, they prove they're shit lol. To suggest that the reliablity of a modern BMW motor is "legendary" and up there with 90's Toyota motors is quite frankly hilarious. "Considering what it's made of" LOL Too much plastic is the answer!
@@addz17 I was hypothesising about the B58's future status and yes I do know that BMW has made some terrible engines in the past, but they have also made some very good engines.
@@addz17 the B58 has been around for quite some time ? idk why jdm fanboys like to generalize a car manufacturer by their engines (or maybe checking oil every 5k miles is not in their book) like , toyota putting in a BMW engine literally tweaked to nothing and slapping it on a new chassis was pretty much funny imo ... they opened up the motor to see it actually met their standards of quality and shoved it in their own car like what other particular manufacturer does .
Amazing engine. I'm driving a M240i with upgraded turbo and fuel system running over 600hp/800nm as a daily. Very fuel efficiënt for normal driving and never boring when you step on it. So far after 3 years. 0 problems. People who buy this engine and tune it will hopefully care more for maintenance , so you will never see many issues.
I’ve owned my 2018 340i Xdrive since 2018 & it’s had 0 issues and is at 87K original miles and counting. If y’all are needing proof of this, I have it. I’ve kept it in its stock form & I assure anyone doubting this engine can put all those doubts to rest. The only thing I’ve done is general maintenance & a coolant flush. It’s been bullet proof. Even went through 3 wrecks, got it fixed each time & still has not a single mechanical issue. At first I thought it was a piece of shit, and now over time has proven to me maybe it was the car for me all along & I doubted it too much. Obviously after hitting 100K + we’ll see truly how great this motor either is or not. I’ll keep you all posted. Have thought about posting high mileage b58 content for some time especially since I’ve tried to take great care of my 340 in the 4 years I’ve owned it.
I have 46000 miles on my 2020 supra, it' got a tune running 22lbs of boost along with a downpipe and intake from about 7k miles, and running water meth injection, and e60 since 15k miles making over 500whp driven through long cold Michigan winters that can regularly get in the negatives (farenheit) and occasionally double digit negatives along with feet of lake effect snow, along with relatively hot summers regularly 90 degrees (farenheit) overall the car has been completely bulletproof with zero issues and I would definitely recommend any car with the b58 and especially the newer models with the TU fuel pump that can flow enough volume for ethanol mixtures
That is a lot of boost for that compression ratio. Call this an intermediate engine as the next version will have to add port injectors to keep intake ports and valves clean.
Not necessarily about the compression ratio. The variable cam timing adjusts the dynamic compression of the engine and the sophisticated knock control helps with keeping uncontrolled combustion events down.
@@hoost3056 Nice then. Reying on fail prone electronics to keep it from self detonating is a foolish design. Electronics are always the 1st thing to fail in a car!
@@VisioRacer, Stephan Papadakis did just that when he built his B58 for his drift Supra. It went over 1000 HP. Reason he did that was, besides not actually using the direct injectors, they were destroyed during dyno sessions.
The crankshaft is easily 1k horsepower capable, as Frederic Aasbo, FD driver driving a A90 Supra, uses a stock crankshaft. It was a stock block and crankshaft built by Papadakis Racing, which was one of the clips shown in this video.
Going B58 after 15 yrs of unboosted V8's, it takes some time to get used to driving with a sea of torque in low RPMs. I still don't like it ocmpared to naturally aspirated engines, but it makes for a pleasant flexible engine with - indeed - excellent MPG for its HP output. I essentially went from 18.8-23.5 mpg with the N62 V8 (4.4l) to 23.5-30 mpg with the B58 (not the TU1). Not the V8 sound I was used to but in sport modus it makes a decent soundtrack. *torque *enough horse power *decent mpg If durabilty also checks out, it's a winner.
It is essentially a modernised 2JZ! And the sound reminds me of an AMC 4.0 below 6000rpm except with an incredible rumble! Ive seen aftermarket exhausts that have made it sound very similar to an RB or the original 2JZ itself!
@@KingChadKennedy Toyota has been making straight 6 engines since the 1930's. Both Toyota and Nissan had made many famous performance inline-6 engines before the JZ and RB. The only reason the B58 is good is because of Toyota's input. The engine had to meet Toyota's strict quality control. During testing Toyota sent thousands of B58 parts back to germany with notes for improvements.
@@electrikoptik BMW started building inline sixes in the 30’s, too; maybe even beating Toyota by a couple of years. The Toyota straight six was an identical knockoff of the Chevy Stovebolt 6, parts could even interchange.
@@davej6222 Factually incorrect, the Stovebolt 6 is similar to F series engines as used in early Landcruisers. None of the parts are interchangeable though the I-6 engines do look similar. Fixtures and fittings are a off position compared to stovebolt 6. The JZ line are NOTHING to do with the F-series designs as its immediate successor was the M-series.
Besides the shortcomings of the location of the cam timing and oil pump chains, the plastic parts breaking down with time, and no port injection to maintain clean intake ports, the B58 is an engine with very high tuning potential. Regular oil changes will greatly reduce chances of VANOS and Valvetronic failure, and a catchcan will mitigate intake port carbon buildup.
@Automobile Addict, there are far more worse European engines. No engine is perfect. Objectively, many engines from many manufacturer come close to perfect. Which has their fans. Even those considered "unreliable" by many are seen as challenges to improve them by many. Take the Subaru boxer and Mazda Wankel, for example. But even the LS engine isn't bulletproof if you neglect its maintenance or push it beyond what the parts are capable of handling.
Like I said in a previous comment, these engines don’t have carbon build up due to the way their PCV system works. High mileage B58s have been opened up to find zero carbon build up on the valves. Also given that it’s an inline-6 you should never have to service the timing chain or guides for the life of the car.
@Automobile Addict The actual engine reliability should be fine. Toyota corrected BMW's mistakes. Check out this video on the Z4/Supra - there's a very interesting quote from one of the main engineers from BMW on Toyota's approach to doing things. As for the ancillary components, plastic crumbles over time so replace with metal parts where possible. 👉 ua-cam.com/video/_jbyzmtgU_0/v-deo.html
BMW inline-6 are simply awesome! I would love to see a video about the legendary inline-6 engines of the E46. M52, M54, S54 and P54. I drive a M54B22, and maybe it's slow, but it makes me so happy!
Intake Carbon is pretty much a non issue now. Pcv ports aimed at each valve along with creative injection timing strategies. They solved it years ago. Even mini n14 engines with new software after cleaning. Rarely need it done again.
Drove a 340i half an hour ago. The pull that I experienced from 45 to 115 in full throttle was the most eye opening experience I’ve had in a long time. Still can’t believe how powerful this engine is in stock form! ❤UNREAL!!!❤
I spent quite some time searching for the right 6 cylinder BMW with a manual transmission. Landed on the 340i xDrive and have no desire to look elsewhere
So glad they ditched the electric water pump- I nearly froze to death one night when mine failed in the middle of nowhere in sub-zero weather. But those unreliable VANOS solenoids on the back of the engine? Stupid!
This has been a problem since the E8X, maybe earlier. Mine went in my N54 135i out of nowhere. Car shut down the engine immediately while I was driving with a overheat warning ⚠️. I get that it wanted to save the engine but it was dangerous, I had to force my way sideways through traffic to get onto the shoulder, all while coasting with no power and people having to avoid ramming me.
@@J_S591 Yeah- the water pump, plus going into limp mode for no reason a few times, plus the run flats leaving me stranded (I live in NM- you can't find those things outside most places) means I stopped driving my low mileage N54 335i on road trips and took my 250k mile 95 Jeep Cherokee instead. I trusted the Jeep to actually get me where I was going. In all those miles it never left me stranded once
@@CrazyWeeMonkey UZ. Revive the Soarer, the A90 is more of a Soarer than a Supra in any case. Put in the latest V8, bubble up the roof, elongate the tail, styling is whatever because I don't know any company besides Mazda who still make good looking cars. Job done.
@@CrazyWeeMonkey Basically, but I hate the fact it's a 2-ton car, I hate the F spirit whatever edgelord styling, it's obviously aiming to compete in the SL's or 8-series' ballpark and that is *just* not the point.
BMW Inline 6s are the german 2JZ I see nobody else among the german brands making anything comparable. Update: So far nobody here has any serious issues with them. Ive seen one in the shop because a piston broke apart below the rings due to very bad knocking presumably. It looked like a typical failure you see with too much boost/very bad knocking. Car was tuned to 400hp so excessive boost wasn't the problem. Engine went back together only needing a piston everything else was in great condition. Techs said this engine was significantly beefier and has less wear than the N55 they usually have to patch up 😅
The Mercedes-Benz OM606 is considered the German diesel 2JZ. Great for when you want a high revving equivalent to a tuned Cummins 6BT without its high complexity and huge size and weight.
@@evolife1044, no doubt. Nissan has restarted making new RB26 engines as part of their heritage program. I don't know if Toyota will do the same with their 2JZ. Just don't count out newer engines out yet. Honda B-series builders said the K-series were trash when they first came out. Now you can K-series swap (almost) anything.
Glad to see you cover this engine! It's an absolute gem, even when paired to a 6-speed like my 240 Quick thing to be noted: the original build B58 had the 6-exhaust port head (I could literally take a picture of my engine bay to prove this.) TŪ1 brought the headers-in-block arrangement, for efficiency. The engine warms up quicker when the exhaust gasses are heating up the head, improving cold-start emissions. ~The compression ratio is unchanged as well, still 11.0:1. 10.2:1 is the N55 ratio.~ EDIT: I was half-wrong about compression ratio; B58B30M1 (335hp TÜ, as found in 540i, 740i etc) remain 11.0:1, while B58B30O1 (382hp TÜ found in M340i, M440i etc.) have dropped down to 10.2:1.
Can you show me your source of the compression ratio? As far as I can find, the 2021 model does have the 10.2:1 compression ratio www.toyota.com/content/ebrochure/2021/gr-supra_ebrochure.pdf
@@VisioRacer Wow, I thought I knew everything there is to know about these engines. I was half-wrong; B58B30M1 (335hp TÜ, as found in 540i, 740i etc) remain 11.0:1, while B58B30O1 (382hp TÜ found in M340i, M440i etc.) have dropped down to 10.2:1.
I've noticed alot of famous high-power German engines use diesel engine blocks. The VW VR6 was originally meant to be a diesel engine so it has very thick cylinder liners which is why it can handle so much power and boost stock. B58 is the spiritual successor to the 2JZ and VR6 in my opinion
The B58 is a much more modern engine than the 2JZ ... you really can't compare. Big power Supras are supported by aftermarket engine and driveline parts (and ECUs!) ... the B58 will get there in time.
Yeah but remember Toyota went through the whole engine and components and made sure it passed their standards before placing it in the supra what failed was sent back to bmw and remade
Can you talk about the Volvo Modular engine family, especially the B52 line? Turns out white blocks have forged internals and people aren't really going and having fun with it.
Time will tell on reliability of these. In the UK they are much rarer than the 4 cylinder petrol and Diesel BMW engines and they tend to cover less miles. What I will say though is that a few have had broken pistons, injector failures and scored bores. They seem reliable in most cases but may not be as bulletproof as many people think. The official long service intervals, single row timing chain and the fact it is mounted at the back of the engine are not a great combination either and that setup has caused issues in the past. Mine is on 53k and going strong but does have the occasional tick and rattles which come and go.
And remember that this engine is part of the modular engine family. Meaning that you can get similar architectures on 4 and 3 cyl engines (cheaper ones).
I just got this feeling, with time and milage we shall see a lot more engine out repairs due to that timing change re-location.....only time will tell.
While that block and head looks pretty beefy, I'm looking forward to all the money I'm going to be making off of these at the 70-90K mile mark when all that Bavarian plastic succumbs to that intense heat and pressure.
Yeah blame the stupid green peace and government to put more restrictions on emission so every car manufacturers has to use plastic in order to save fuel consumption
It's new... Having owned BMWs and knowing the history of bmw's quality over the years... I think it's only smart to really let it see the test of time. (I love what you get out of box with this motor, but honestly the fact bmw makes it... Would push me in just about any other direction)
I have had a G31 since 2017 with b48 and it has been absolutely bulletproof, has 100k miles on it right now. That should be an indication as B58 is B48+ 2 cilinders :)
my dad used to own a 3.0 CSL and beat on it for 20-30 years ish until i was born in 2003 and when he sold it, it ran like it was new. what people see about bmw’s “bad” reliability is americans thinking they can rev the shit out of em and go fast when it hasn’t warmed up yet. i have not seen a single broken down bmw in my life. in reality they’re really really really reliable
People hate on the A90 Supra because it's not a Toyota. But there is enough Toyota in this BMW Z4 coupe to let you know that Toyota had involvement in this joint development. They even made it easy for people to eventually 2JZ swap it. Yet the current GR 86 and the previous generation didn't get much hate despite being joint developed with Subaru.
@@JoseRivera-ym3wj Because the A90 is closer to a Soarer, being co-deved with a luxury brand. I really do not understand why the 86 got off with as little as it did because inherently a new AE86 is not legal/profitable. The GT86 is nothing but copium.
He made a mistake; it's the other way around. It went from 6-port to 2-port, to improve cold-start emissions. Headers-in-block means the engine warms up much quicker. Not sure about flow, but apparently it's completely fine.
Ever since they switched to the B engines (B48 2.0T, B58 3.0T) they've shot up significantly in reliability metrics. iirc they began to implement bunch of Toyota manufacturing standards/methods around 2013 and their current cars are much better as a result.
I own a 2020 supra 3.0 & I can confirm it does burn oil fast. A friend of mine also has the same problem with his supra. Many German performance engine loves to burn oil. Keep a quart or 2 of oil somewhere in the car so when the low engine oil warning comes on just top it off.
The vanos are replaceable with engine and transmission in the car nos issues ! They are very short and not very hard to get out. The only thing that is hard to do is REtiming the engine if example changing timing chain and cams sprocket are easy to take out if you have the tool. Overall, good engine !

Happy to be an owner of this amazing engine on my M340i ! Not going to tune it. I stick to the idea that the manufacturer did everything he had to make this engine so durable, so tuning it won’t be a good thing to do imo
Plenty of potential left, if you drive it slow when its colt etc there wont be an issue. Tuned my 335i N55 at 110.000km and this machine runs smooth as ever 3 years counting, zero issues. 380hp 550nm , pulls it every day no problem.
Seen plenty stock m140i/m240i on the dyno before they got tuned and they are around 340-360hp. You are exaggerating with 380-390hp lol. Mine for example with stock ecu but with catless downpipe made 365hp and 540nm
@@zdx197 Then how does it trap 110+ mph in the 1/4 mile? The m240i weighs 3400+ lbs, and traps 110-112. That's indicative of a car with at least 320-330 whp. Compare across all American and Japanese makes and models for verification. The German brands all publish approximate WHP as crank HP for their turbocharged models. This has been true for 10+ years.
@@zdx197 I've seen dynos of stock gen 1 b58s making 320-340 whp. I've also seen some making 290-300. This is why I brought 1/4 mile trap speed into the conversation. That's the most reliable indicator of a car's true power to weight ratio. Either someone's dyno is lying, or there's some bad gas in some of these cars, because only in Germany does a 3400+ lb car with 290 whp and 330-340 at the crank run 12's at 110+ mph. That doesn't happen with American, Japanese, or Korean models.
Great video - I have a 2020 540i which has an upgraded TU B58 however is the B5C variant with the two port head. In your opinion is this still a strong engine which would be suitable / reliable for some slight modifications such as a stage 1 tune to bump the HP/torque into the 400-420 range? Thanks
@@surfside75 Not necessarily, torque curves between a V6 and Inline-6 with identical Bore x Stroke should be about the same, though an inline-6 may be able to make more torque & horsepower because it's smooth balance requires lighter balance shafts and lets it rev higher. The advantages of V6's relate to their packaging. They are much shorter (length), meaning they don't require hoods as long, and physically lower (height), giving a lower center of gravity and the ability to have a lower hood. But they are wider.
We have a B58 engine in our BMW. It is an OK engine, but it is also the reason why we are leasing this car, despite me having a fully equipped shop. This engine has too many Achilles Heels with potential for VERY costly repairs, all the way to engine replacement. Calling this engine good is a bit short sighted.

Thanks for featuring this engine. I will be putting a built one in the aluminum-skinned BMW M1 replica. The suspension will be Lancia 037 clone.

No the B58 is incredibly reliable, one of the only problems is the timing chain placement (not affecting reliability but is tricky to repair) and carbon build up over long periods of time, but there are many solutions to clean the engine. An example of an unreliable BMW is the N54. The N54 itself is a brilliant engine, but the auxiliary parts such as the high pressure fuel pump let it down. Replacing all these faulty parts will make an N54 very reliable. Other unreliable BMWs include the N47, early N20s, and the N62/N63. These are naturally unreliable engines.
please make a video about the s54,55,58, also the tuning side of things, show us some builds of respected brands like ac schnitzer or alpina, i fkn love alpina!
@@VisioRacer Papadakis Racing has a full teardown video of the engine. The can wheels are at the back of the engine, which makes the simple task of changing camshafts very complicated requiring engine removal just to get better camshafts. The variable lift system is very complicated to remove. The intake manifold is PLASTIC. The oil filter housing is PLASTIC. The thermostat housing is PLASTIC and computer controlled for no reason, overcomplicating a proven system with electronic control. Also, if you desire to have a normal thermostat system, the computer in the car will not allow the far to function due to the computer controlled thermostat. The valve cover is PLASTIC. All that plastic around heat and pressure is asking for fatigue and deformation causing leaks and poor sealing, asking for low oil pressure, not something I want for a 80k dollar Supra. The internal exhaust manifold eliminated the possibility for exhaust porting for better power. The engine does not fit on a basic engine stand that can hold 99% of all engines making it a neusance to work on even outside of the car. Spark plug holes are very very small, making replacement another neusance. The connecting rod caps are cracked for a more exact fit on the crank, which in my opinion is less accurate than a simple ground or machined finish on the rod caps. The cylinder head has a very high part count in order to achieve the variable valve lift, much more complicated system than the 2JZ as well with a direct cam on shimmed bucket system instead of the finger follower system. When Papadakis rebuilt the B58 for high power, the intake manifold was changed to aluminum for better strength, so the argument of plastic used as stock for better weight holds no value. Let me know if you have any questions.

If you notice there has been a huge push for 340i from the f30 generation and these motors do produce more power than the n20 or N26 but are prone to some very similar malfunctions, especially rod knocking. I heard BMW is pushing influencers to promote these for viewers buy old stocks to get them moving faster.
This is not true in any way shape or form. The f30 generation has been out of production for several years now, there’s no remaining stock and hasn’t been for some time.

In stock form, the B58 is a gem of an engine. It's super smooth, has torque for days, revs quickly, and gets great fuel economy when not pushing it. Can't speak to the longevity of it, but in terms of operation, it's an absolutely brilliant motor.
Considering what it is made of, the tuneability and overall feedback of reliability so far, my predictions are that the engine will soon have a legendary reputation for reliability, up there with the M50/M52, N52, K series, 2JZ, Cummins 5.9 1.9tdi, Om606/OM617 and also the 3 cylinders found in the Geo metros/Suzuki swifts.

That is a lot of boost for that compression ratio. Call this an intermediate engine as the next version will have to add port injectors to keep intake ports and valves clean.
Not necessarily about the compression ratio. The variable cam timing adjusts the dynamic compression of the engine and the sophisticated knock control helps with keeping uncontrolled combustion events down.

@@VisioRacer good plan!
DI has advantages, but port injection keeps engines alive. A combination like Toyota uses seems to be a happy medium.
@@VisioRacer, Stephan Papadakis did just that when he built his B58 for his drift Supra. It went over 1000 HP.
Reason he did that was, besides not actually using the direct injectors, they were destroyed during dyno sessions.
The crankshaft is easily 1k horsepower capable, as Frederic Aasbo, FD driver driving a A90 Supra, uses a stock crankshaft. It was a stock block and crankshaft built by Papadakis Racing, which was one of the clips shown in this video.
Going B58 after 15 yrs of unboosted V8's, it takes some time to get used to driving with a sea of torque in low RPMs. I still don't like it ocmpared to naturally aspirated engines, but it makes for a pleasant flexible engine with - indeed - excellent MPG for its HP output. I essentially went from 18.8-23.5 mpg with the N62 V8 (4.4l) to 23.5-30 mpg with the B58 (not the TU1). Not the V8 sound I was used to but in sport modus it makes a decent soundtrack.

BMW made inline 6 engines way before the JZ so the JZ and RB came after BMW with their inline engines
@@KingChadKennedy Toyota has been making straight 6 engines since the 1930's. Both Toyota and Nissan had made many famous performance inline-6 engines before the JZ and RB. The only reason the B58 is good is because of Toyota's input. The engine had to meet Toyota's strict quality control. During testing Toyota sent thousands of B58 parts back to germany with notes for improvements.
@@electrikoptik BMW started building inline sixes in the 30’s, too; maybe even beating Toyota by a couple of years. The Toyota straight six was an identical knockoff of the Chevy Stovebolt 6, parts could even interchange.

Besides the shortcomings of the location of the cam timing and oil pump chains, the plastic parts breaking down with time, and no port injection to maintain clean intake ports, the B58 is an engine with very high tuning potential.
Regular oil changes will greatly reduce chances of VANOS and Valvetronic failure, and a catchcan will mitigate intake port carbon buildup.
@Automobile Addict, there are far more worse European engines. No engine is perfect. Objectively, many engines from many manufacturer come close to perfect. Which has their fans. Even those considered "unreliable" by many are seen as challenges to improve them by many. Take the Subaru boxer and Mazda Wankel, for example.
But even the LS engine isn't bulletproof if you neglect its maintenance or push it beyond what the parts are capable of handling.
Like I said in a previous comment, these engines don’t have carbon build up due to the way their PCV system works. High mileage B58s have been opened up to find zero carbon build up on the valves. Also given that it’s an inline-6 you should never have to service the timing chain or guides for the life of the car.
Always warm the engine, bmw oil only, shell 93 and it runs forever
@Automobile Addict The actual engine reliability should be fine. Toyota corrected BMW's mistakes. Check out this video on the Z4/Supra - there's a very interesting quote from one of the main engineers from BMW on Toyota's approach to doing things. As for the ancillary components, plastic crumbles over time so replace with metal parts where possible.

@Automobile Addict I always warm up my B58. If you don't you deserve something on it to break down.
BMW inline-6 are simply awesome! I would love to see a video about the legendary inline-6 engines of the E46. M52, M54, S54 and P54. I drive a M54B22, and maybe it's slow, but it makes me so happy!
I look forward to getting my hands on a B58 this Summer.
Intake Carbon is pretty much a non issue now. Pcv ports aimed at each valve along with creative injection timing strategies. They solved it years ago. Even mini n14 engines with new software after cleaning. Rarely need it done again.
Happy owner of a M140I with this engine, pure pleasure for a decent price tag.
The N54 , N55 and B58 sounds amazing
Drove a 340i half an hour ago. The pull that I experienced from 45 to 115 in full throttle was the most eye opening experience I’ve had in a long time. Still can’t believe how powerful this engine is in stock form! ❤UNREAL!!!❤
1:37 A bug is very interested in the engine as well! :0 xD But man, what a nice engine! Love these overenginered engines.
I spent quite some time searching for the right 6 cylinder BMW with a manual transmission. Landed on the 340i xDrive and have no desire to look elsewhere
So glad they ditched the electric water pump- I nearly froze to death one night when mine failed in the middle of nowhere in sub-zero weather. But those unreliable VANOS solenoids on the back of the engine? Stupid!
This has been a problem since the E8X, maybe earlier. Mine went in my N54 135i out of nowhere. Car shut down the engine immediately while I was driving with a overheat warning ⚠️. I get that it wanted to save the engine but it was dangerous, I had to force my way sideways through traffic to get onto the shoulder, all while coasting with no power and people having to avoid ramming me.
@@J_S591 Yeah- the water pump, plus going into limp mode for no reason a few times, plus the run flats leaving me stranded (I live in NM- you can't find those things outside most places) means I stopped driving my low mileage N54 335i on road trips and took my 250k mile 95 Jeep Cherokee instead.

BMW Inline 6s are the german 2JZ I see nobody else among the german brands making anything comparable.
Update: So far nobody here has any serious issues with them. Ive seen one in the shop because a piston broke apart below the rings due to very bad knocking presumably. It looked like a typical failure you see with too much boost/very bad knocking. Car was tuned to 400hp so excessive boost wasn't the problem.
Engine went back together only needing a piston everything else was in great condition.
Techs said this engine was significantly beefier and has less wear than the N55 they usually have to patch up 😅
The Mercedes-Benz OM606 is considered the German diesel 2JZ. Great for when you want a high revving equivalent to a tuned Cummins 6BT without its high complexity and huge size and weight.
The VW EA888 (2.0T) can be boosted comically high on stock internals. It's not an inline 6 but it's still a very strong powerplant for it's size.

Glad to see you cover this engine! It's an absolute gem, even when paired to a 6-speed like my 240
Quick thing to be noted: the original build B58 had the 6-exhaust port head (I could literally take a picture of my engine bay to prove this.) TŪ1 brought the headers-in-block arrangement, for efficiency. The engine warms up quicker when the exhaust gasses are heating up the head, improving cold-start emissions. ~The compression ratio is unchanged as well, still 11.0:1. 10.2:1 is the N55 ratio.~
EDIT: I was half-wrong about compression ratio; B58B30M1 (335hp TÜ, as found in 540i, 740i etc) remain 11.0:1, while B58B30O1 (382hp TÜ found in M340i, M440i etc.) have dropped down to 10.2:1.
Can you show me your source of the compression ratio? As far as I can find, the 2021 model does have the 10.2:1 compression ratio

Can you talk about the Volvo Modular engine family, especially the B52 line? Turns out white blocks have forged internals and people aren't really going and having fun with it.
Time will tell on reliability of these. In the UK they are much rarer than the 4 cylinder petrol and Diesel BMW engines and they tend to cover less miles. What I will say though is that a few have had broken pistons, injector failures and scored bores. They seem reliable in most cases but may not be as bulletproof as many people think. The official long service intervals, single row timing chain and the fact it is mounted at the back of the engine are not a great combination either and that setup has caused issues in the past. Mine is on 53k and going strong but does have the occasional tick and rattles which come and go.
And remember that this engine is part of the modular engine family. Meaning that you can get similar architectures on 4 and 3 cyl engines (cheaper ones).

The head was upgraded from a 2 port exhaust to a 6 port exhaust due to restricted airflow? Didn't see that coming

Ever since they switched to the B engines (B48 2.0T, B58 3.0T) they've shot up significantly in reliability metrics. iirc they began to implement bunch of Toyota manufacturing standards/methods around 2013 and their current cars are much better as a result.

Not necessarily, torque curves between a V6 and Inline-6 with identical Bore x Stroke should be about the same, though an inline-6 may be able to make more torque & horsepower because it's smooth balance requires lighter balance shafts and lets it rev higher.

@@jaimatic23 🤦🏽♂️
It baffles me that any manufacturer would not use a combination of direct injection and port injection to keep the backside of the intake valves clean nowadays.
It only needs to last the 3 year lease period. From there second owner pays them mountains of money in repairs.
Thanks for featuring this engine. I will be putting a built one in the aluminum-skinned BMW M1 replica. The suspension will be Lancia 037 clone. There’s a Ford Cobra fabricator in Utah I believe can do the bodywork. Feels like I can get it done for around 250k. Doesn’t really matter. I’ve got a rich 82 year old dad. He won’t last forever.
what the fuck?
Daddy daddy daddy
@@AlienLivesMatter Too bad you don’t know who yours is. Mine is going to leave me a fortune that I can do something unique and interesting with. Jealous much? LOL. Better luck next life.
Will it still have vcg and oil filter housing leaks tho?
If it's a BMW, leaks are guaranteed.
Whoever buys it second hand with high mileage and has to replace the timing chain I feel sorry for them…
Most diesel bmws have had that desígname they don’t break at all 90k on mine full e85 for 3 years with 500whp no issues
@@Justanothercarguynyc 500whp lol sure
@@RandomGuy-ej9gr bro you're looking mad dumb right now. 500whp in these is a cakewalk. It is even done with stock turbo in the right drivetrain.
Gen 1 is 6 port. gen 2 (Supra /Mx40i) went to 2 port btw 👌🏼great vid
Yeah I got confuse for a sec
Plastic crap that will break with time because of heat and it will cost a fortune to replace. You got the chain on the firewall side. Direct injection so your valves will be cloged.
@footballcoreano still spouting the BS I see 😂 Do you actually believe the utter drivel you comment?🙄🤡
I've seen some intake manifolds break on the B58. Only @ 40+psi of boost (:
Not your average power levels...
BMW straight 6s sound so good, it's a shame i don't hear them much at all.
But not the best reliability
What are the most common issues with B58 that you know of, out of curiosity.
At least it has warranty
B58 is very reliable..
Dude. Toyota picked it up for their most legendary icon car, its damn fucking Toyota
That itself justify reliability for me
No the B58 is incredibly reliable, one of the only problems is the timing chain placement (not affecting reliability but is tricky to repair) and carbon build up over long periods of time, but there are many solutions to clean the engine. An example of an unreliable BMW is the N54. The N54 itself is a brilliant engine, but the auxiliary parts such as the high pressure fuel pump let it down. Replacing all these faulty parts will make an N54 very reliable.
Other unreliable BMWs include the N47, early N20s, and the N62/N63. These are naturally unreliable engines.
please make a video about the s54,55,58, also the tuning side of things, show us some builds of respected brands like ac schnitzer or alpina, i fkn love alpina!
N52 is still best
Dude. The technical update is the two channel exhaust outlet cylinderhead. The 6 channel is from the first version.
Thanks for showing the B58 is NOTHING like the 2j and can't be compered to the 2j
We are both on the same page. The B58 surpassed the 2JZ. I do not know why people compare them.
The s58 is even impressive
@@negropen 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Does anybody know where the secondary air pump is? That throws the codes on this motor ?
From the point of view of someone that works on engines, the B58 is a pile of shit.
Feel free to share details
@@VisioRacer Papadakis Racing has a full teardown video of the engine. The can wheels are at the back of the engine, which makes the simple task of changing camshafts very complicated requiring engine removal just to get better camshafts. The variable lift system is very complicated to remove.
The intake manifold is PLASTIC. The oil filter housing is PLASTIC. The thermostat housing is PLASTIC and computer controlled for no reason, overcomplicating a proven system with electronic control. Also, if you desire to have a normal thermostat system, the computer in the car will not allow the far to function due to the computer controlled thermostat. The valve cover is PLASTIC. All that plastic around heat and pressure is asking for fatigue and deformation causing leaks and poor sealing, asking for low oil pressure, not something I want for a 80k dollar Supra.
The internal exhaust manifold eliminated the possibility for exhaust porting for better power. The engine does not fit on a basic engine stand that can hold 99% of all engines making it a neusance to work on even outside of the car.
Spark plug holes are very very small, making replacement another neusance. The connecting rod caps are cracked for a more exact fit on the crank, which in my opinion is less accurate than a simple ground or machined finish on the rod caps.
The cylinder head has a very high part count in order to achieve the variable valve lift, much more complicated system than the 2JZ as well with a direct cam on shimmed bucket system instead of the finger follower system. When Papadakis rebuilt the B58 for high power, the intake manifold was changed to aluminum for better strength, so the argument of plastic used as stock for better weight holds no value.
Let me know if you have any questions.
@@joshlewis5065 Yeah, most of the info is mentioned in the video and I agree. That’s why BMW engines are kinda known as fragile. There is always something that pops up and requires an expensive replacement.
@@VisioRacer I personally have 2 2jz engines, have have had both of them apart all the way down to the long block. There is nothing to them, especially the non vvti engines. I just wish they had 4 bolt main bearing caps instead of just two. And it would be asking a lot but gear driven cams would be nice as well as finger follower cams for the most reliable high rpm operation
🤣🤣 Pray to the Vanos gods!
The torque on this engine is fucking crazy.
For me this B58 engine are suck .
I rather recommend M50 with 3.0 stroker build and add a turbo
Explain the reason.
@@derekj.tejeda267on m50 price for engine and parts is cheaper, simplicity of building and maintening it, sound is better , reliability if built properly will last a good ammount of years. There has been a b58 engine swap on a e36 though check it out on youtube
All BMW IS JUNK
Best sounding i6 🎉
As a b58 owner. No it’s the n55 that sounds the best but n55 is a POS
Trust me, the B58 will be about as effective as the B-58 bomber. Fast for a short time, but NOTHING BUT TROUBLE in the end~
Like almost all engines?
@@derekj.tejeda267 Like almost all modern BMW engines.
@@Flies2FLL I disagree.
@@derekj.tejeda267 There are quite a few independent foreign car shops that simply will not touch a BMW because they are so much trouble to work on, and customers invariably take out their aggravation on the shop, blaming the mechanics instead of the excessive complexity and poor engineering.
Don't get me wrong, I like BMW's, but I would only lease one. I'd NEVER own a contemporary BMW.
@@Flies2FLL That's okay.
Not a BMW guy but hearing the exhaust notes with pops and bangs omg. Also seen a video on a X3M being tuned making around 700whp I believe. So the engine has more potential.
I'm currently on BM3 stage 2, but I have complete peace of mind with the B58 - sounds amazing, brings lots of power, and can be economic when needed.
Hey bro. I’m looking into the same car same tune, how’s it been realibly
@@f22_b58 rock solid - these engines are made for tuning
@@f36_garage71 Damn bro that’s so sick okay! I was gonna save up and go with a b9 s4 or maybe just get a b8.5 s4 but imma go with a 340i I think… Or do I spend a little more and get a m240i, I hear those are better but I’m not sure why if they have the exact same engine
Did they fix the valvetronic motor that was faulty on low mileage in the N55 engines?
1:37 somone has fly in the engine. :D
The B58 is an excellent engine. Pretty much anybody with half a brain knows that and the sales numbers back that up. To the people bad-mouthing to powerplant, I get it. You can't afford BMW but work hard and don't take shortcuts and one day you will hopefully be in a position to buy one.
These type of people who fuss and complain about the pricetags, obviously don't know that the Fourth generation Supra(MK4 A80) was expensive also. And a crap seller at that
Not so sure about reliability after just 105,000 miles...
This is not spam... I really need help with this.
My 2017 BMW 540i G30 just burned a valve #4 cylinder. (105k miles) I had the vsfr high flow cat, upgraded charge pipe, k&n air filter, new B58TU Fuel pump, and Bootmod3 Stage 2+ 93 octane.
I am beyond depressed! Single Dad with special needs, kid. I was told I need a new engine. 21k installed. I just can't. I still owe 25k, and it is my only car. I have nothing right now and am about to lose my job. I can't get my kids to the doctors, etc... If you can reach out to your connections and see if they can help, I would be forever grateful 🙏
A rebuild and breakdown of what went wrong with my B58 might help others with B58.
God bless you, brother!!!
~J. McCall
Always best to keep them stock, once you start pushing it that’s when you run into issues. I’m 118k almost on my g30 but I’m stock no issues
You cant judge on reliability if you startd modding, is like judging a burger after sitting on a freezer for a month... i hope your situation got better. My 340i is at 100k miles and trouble free
There’s a loud ticking sound during cold start and the local agent says it’s the injection - really?
When I rev hard, I can also hear it from the cabin.
Are these normal or something is not right?
It's normal for direct injected vehicles. You are going to drive yourself nuts if you try and repair that
wtf is the dead insect doing in the block at 1:37 ??
Did anyone else notice the dead fly inside the piston during assembly? 1:36 🤣 That explains the higher compression.
The block and all the internals are solid. It is all those BMW plastic parts that worries me;)
If you notice there has been a huge push for 340i from the f30 generation and these motors do produce more power than the n20 or N26 but are prone to some very similar malfunctions, especially rod knocking. I heard BMW is pushing influencers to promote these for viewers buy old stocks to get them moving faster.
This is not true in any way shape or form. The f30 generation has been out of production for several years now, there’s no remaining stock and hasn’t been for some time. As someone who works as a tech in a BMW dealership I’d love to see where these B58s with rod knocking are because I have yet to see a single one with this issue since this engine was released, and I typically see a dozen of these engines a day.
What’s is your honest opinion on the N26 engine? Always wanted to ask a technician, thank you.
@@taylorparker8912 The N2x is fine if you can find a 1/2015 build date or later with the updated timing chain design or if you can find an earlier model that's already had the timing chain fix done at your local BMW dealership. Personally if you can afford it I would recommend stretching for a B48/B46 powered BMW as those generally have zero issues to begin with + BMW made the switch to silicone instead of normal gaskets in the Bx8 engines so gasket issues are significantly rarer, which was a common complaint with any N series engine especially as they aged.
Is there any manual trans for B58?? Convert, plug n play .. etc
probably, can't give you any directions tho. Im sure someone has done it tho.
not easy. AFAIK, nobody has even tried it
140i were available as a manual
140i, 240i, 340i, 440i and the supra gr is coming soon with the manual transmision
They just came as manual from factory, at least most of the BMW B58 equipped models such as F2X, F3X
Is the B38 1.5 3 cyl simply half a B58 3.0 6 cyl?
