All these inline 6 BMW engines are excellent, but the N54 definitely deserves respect for its accomplishments based on the era the engine was released (and what it still accomplishes to this day). It cost about 180 Euro. Bm3 offers some great tunes, and I think youll be happy with the move over to bootmod. Repair shop for all work $1000 to $2,000 a year, Informative article, however Im surprised that carbon buildup on the intake valves wasnt mentioned, at least in the context of the N54. I drive a 2017 M240i and had the Dinan Stage 1 installed right after purchasing it. Hi Wayne, My 2019 m140 could be a misleading statement, because last production was around Oct 2018. BMW B58 vs. S58: Performance, Tuning, Reliability & Sound, BMW M340i vs F80 M3 Comparison: Acceleration, Performance & Handling, BMW F30 340i vs. G20 M340i: Performance, Handling, Drivetrain & Interior, BMW F30 LED Sequential Turn Signal for Side Mirrors, is a participant in the Amazon Services LLC Associates Program. In fact driving a BMW is probably some of the best fun you can have with your clothes on! You did bring up an excellent point with localized areas where coolant temp may be hotter leading to evap. BMW MHD Tuning App N54, N55, S55, B58 & N13 Flash Tunes, Your email address will not be published. Now I still experience a bit of coolant loss, but much, much less. Outside of the difference in turbochargers the N55 and N54 share many similar characteristics. Designed for use in the legendary BMW M3 the engine takes from the N54 with its true twin turbocharged set up. Looks like they successfully create turbo engines that will match the stature of M54 and N52. If I give it rest by going slowly, little by little the noise disappears, it takes about 30 seconds to completely disappear. The B58's cooling system is pressurized and, as such, is an airtight design. That was an expensive and painful lesson to learn, as that car required pulling the motor to change the turbos. The talker a 6th gear I can find the better. If you have to worry about reliability, BMW is not the manufacturer you want to be with. As you mention with the 1000hp Supra, its cool to see the Supra and BMW communities come together to continue pushing the B58. It does not have signs of issues with any of its internal components. Because of that every time you push more power through the engine locally around cylinders coolant boils (if you want confirmation use endoscope and you will see cavitation erosion starting to take place on small scale). Your email address will not be published. We were surprised to find this is not uncommon on other BMW engines, too. Not quite sure wether its a B58 or still the N55 thougj.. any ideas? If you can pull out the broken filter, inspect and clean any debris. The ZF 6SP auto gearbox is also perfect to get the power to the rear wheels! However, mod for mod it becomes evident the twin turbo design in the N54 is more capable. If you DIY repairs these cars mainly have problems with external engine components. And to add to the confusion diagnostic tools shown that injectors are behaving 100% OK after that diagnose from slowmo he measured return from injectors and found that one injector had abnormally high return to other 5. Once the pass side is in and connected, install driver side and connect. Hi mate. First, let me say this is awesome info and Im grateful for it. Just go hard more. Only truly good engines bmw made were M20B20 series(2.0, 2.5 , 2.7) and the big sixes M30B35 along with all its smaller or bigger versions. Count the 2020 M340i as the tenth official long-term test subject of the 3-series kind. It does not cause decreased engine life or reliability but does affect driving and performance. Lets look at both engines in detail to find out why the N55 is not as reliable as the new B58. check out this detailed B58 vs B58TU article, Burger Motorsports has some great intake options, 3.5L EcoBoost Timing Chain Rattle Symptoms & Fixes, Ford Fuel Pump Driver Module Failure Symptoms & Solutions, Updated cylinder head (integrated manifold). Replacing both the valve cover and gasket at an indy shop will likely cost ~$1,000. Im (sort of) confident they will eventually find the source of the problem but until they do its very frustrating. According to my best measure it is about 250ml/1000 Km. 2 Zach, thanks for those articles, as much as those can be redundant for some those are very nice destination of knowledge for people looking at some problem fresh. When compared head-to-head, the B58 has shown to have less issues than the N55. The rough idle is a symptom of the VANOS solenoid. The BMW B58 engine can handle around 600-650whp and 550-600wtq on the stock block and internals. To cut right to the chase, I love the direction the BMW B58 is going. Required fields are marked*. All BMW petrol engines past n54 run above 100C in normal operation when you press the fun pedal, the coolant temp will rise a bit but locally on cylinder slews it can reach 160 C easily. Guess where the VANOS components reside? Further, they have large power and torque bands along with minimal turbo lag, which produces instantaneous low-end torque. Some just keep looking at the past with rose tinted glasses. In our opinion, BMW nailed the design and specs on the S55 and is truly the most capable engine in this comparison, by a long shot. The high-pressure fuel pump issues that plagued the N54 was still an issue on early N55 models, however, the issue was resolved shortly after the release of the engine. The BMW B58 engine is a turbo 3.0L inline-6 that was first introduced to BMW models in 2016. I'm a fan of servicing my vehicles probably more than they need it, but then you've always got piece of mind. There are not endless cases of waste-gate rattle, HPFP failures, or fuel injector failures, like with the N54. A few recalls and service bulletins do exist for the B58. Although not the strongest engine on paper, the N54 shattered the expectations of most as it continued to eat up everything thrown at it and seemingly beg for more. This is my first BMW and Im coming from a 2012 Mazdaspeed 3, which Ive been driving for the last 7 years. 350-400whp will require at least a decent set of performance tires. 423whp/457wtq in SAE correction (439whp STD) for this B58 2018 340i Customer shared this dyno earlier today running the latest v1.6 Stage 2 93 octane (98RON for those in Europe) OTS map. Ive had issues with my 2018 440i not idling correctly. hopefully BMW will sort this out. Washed my hands with it and looking forward to my next car (not BMW). B58 to N55 Comparison. Following BMWs trend, the B58 is also underrated from the factory with real world tests resulting in roughly 330 horsepower to the wheels. It's always the minority of people with issues that shout the loudest. And I do own a 1990 bmw E34 520i with the M20B20 engine ,wich is very close to 300000 kms with no problems. Smoke from the valve cover area is common if the leak is bad enough. However, this may not be necessary in most cases. Deposits can cause misfires and power loss. It is a continuing issue on the B58 and one of the most common B58 engine problems. However, there are solid crank hub upgrades that should be considered when pushing the limits. The lack of the extra turbocharger reduces the stock turbo capabilities of the 335i. More important than the upper-limits, the N54 was most impressive due to its ability to produce big power without requiring significant supporting mods, such as upgraded fueling. Awesome car and congrats on the new tune. Maybe FORD forums are for you? The M340i is a beautiful car and the B58TU is a great engine. Im guessing something might be coming up in future Im not sure if any other b58 owners have this or if its common It . Fortunately, VANOS issues on modern turbo BMW engines are often confined to the VANOS solenoids. Ill try to describe what I suspect as a secondary issue. Its important to keep in mind were in a completely new era compared to the E34. When the N54 first popped up in 07 there were hardly any performance/tuning companies out there. Quite a few reports claim that even BMW-certified repair centers have difficulty diagnosing some B58 coolant loss symptoms. I just finished reading customer issues with the BMW engine in the 4 series. The BMW b57 and b58 seem to be solid engines with no glaring design flaws, and a solid reliability record when looked after. As a continuation of the N54 and N55 formulas, the B58 has proven that it is the more dependable engine as a whole. Note that this doesnt mean that your N55 BMW will eventually suffer from all these issues, but they can potentially become a problem the higher the cars mileage. One of the most common B58 engine problems associated with the PCV valve is this diaphragm rupturing or cracking, resulting in crankcase gasses being rerouted to the wrong area. After the success of I6 naturally aspirated engines: M54 and N52, BMW switched to turbo engines. Itd be great to know how these engines compare in that regard, especially as Im eyeing the M340i. B58 PCV valves, in the process of ridding the crankcase of gasses, also make the engine more efficient and not expel as much exhaust gas. Im trying my best to absorb as much as I can. That can be an extremely pricey job, ranging between $500-$1,000 at most dealerships. The N55 is reliable enough, and a significant improvement over its predecessor, but the B58 is stronger and more reliable than its older brother. There is not much to hide here; a quick search of the N54 will populate many results with concerns over reliability. ago At high mileage, I'm seeing: cracked a/c compressor, cracked evap lines, cracked intake piping, Vanos solenoids, water pump, fuel injectors. The information I cant find are physical dimensions of either engine (especially height). Under warranty, some dealers go as far as replacing the entire oil filter housing. The B58 uses two coolant tanks in its system. Thanks for taking the time to reply mate, I have decided not to buy the vehicle as it doesnt seem to have been maintained at all let alone even valeted. Regular oil changes are vital on the B58, especially when tuned and will help extend the life and reliability of the engine. Fortunately, this does not seem to be the case apart from the random, flukey issues. Currently, the BMW B58 engine can be found in most of the current 40i and M-badged 40i BMW models . Outside of that, meth definitely has some great performance benefits. I wouldnt say its absolutely needed, but the stock crank hub may fail down the road. Ill get to enjoy it a few more days before I say goodbye. This increases performance by. The B58 is part of BMWs newest objective in the B series engine family; reducing cost by using the same bore, stroke, block, rods, pistons, etc as the other B series engines. My regret (not even a problem) was that when moving from E to F, BMW matched gearboxes and diffs more closely to stock engine torques, which in my mind was a bit of step back, because you could always count on 3 things with BMW gearboxes in the past 1. they did not provided greatest feedback 2. they always had decent of headroom potential tune 3. every-time you changed gear you felt like you reloaded WW1 full caliber rifle. Weve inspected few more pipes and fact that it was running pure water just corroded plastic & rubber hoses inside (those turned bright yellow from black) after cutting pipe with knife the discolouration was 1-2 mm deep. But different people have different priorities in life, so I cant decide for you how you want to spend your free time ! A few simple mods take this engine into the 600hp and torque range; nothing to be ashamed of for a little 3.0L inline-6. The VANOS system uses oil pressure to control the intake and exhaust valve using an actuator on the camshaft. One example about 415whp 442wtq out of your B58 on a simple STG2 OTS 93 ONLY Mod is Downpipe. It's worth a shot. In normal condition like drawing to grocery and not even touching accelerator, you will never see this happening, but when doing hard acceleration because you want to get out of dodge, negotiate out of slip road and you need to rapidly gain 40mph, just having fun Happy I stumbled on this website and will definitely be reading more. However, it wasnt as drastic of an improvement as some say. Why? Hello and thanks for the great article! Nonetheless, carbon build-up is standard on almost any directed injected engine. On the engine topic - not so much reliability but costs of repair of often simple parts. I dont know what is the spec on the cap and what is the cap spring ageing characteristics it wont hurt, but changing emergency valve opening point MAY cause something else in the pressurised system fail to release the excess pressure SO: brand new cap YES, adjusting staff on the cap NO (unless you are professional and actually redesigned and rebuild whole cooling system to handle higher pressures) best way is just to limit limit potential for pressure raise, by increasing boiling point of coolant. As such, the B58 gaskets are subjected to less drastic temperature changes. Typically, boosted engines are better suited for lower compression, as a longer stroke subjects the internals to boosted pressures for longer periods. Original BMW coolant (the one in 1.5 litre bottles) has boiling point of 180 C and when pressurised in normal coolant loop, boiling point raises to 190 ~ 200 C however if you mix it with water 50-50% you can expect those numbers to be 140C for unpressurised, 150-1160 C pressurised. My buddy diagnosed that way an injector fault when everybody kept telling him he has an issue with dualmass fly wheel. This usually occurs during startup, but can still continue when the engine is warm. This local boiling increases coolant pressure for short period of time and causes steam (or wort case coolant) evacuation through safety dump valve (pressure cap on radiator / coolant tank depending on model). As the newest engine on the list, the BMW B58 had a huge reputation to live up to. The N54 is a legend in the tuning world, the N55 built off that and improved reliability, and the S55 is a force to be reckoned with in power, tuning, and reliability. Yes, B58 is reliable. Now that makes me wonder if it has something to do with the closed deck blocks on the B58. Stock Power: ~330hpWorld Record HP: 655WHPDisplacement: 2998cc (2.998L)Turbocharger: Single Twin Power TurboCompression: 11.0 to 1Bore x Stroke: 82.0mm x 94.6mm (3.23in x 3.72in)Internals: Forged crank and rods. You can indeed tune an M340i without voiding warranty. Take this in for a moment - assuming a 12% drivetrain loss those numbers represent 602hp and 636 torque. Are both available in RWD with manual transmission? Its a superior design for strength but theyre often more challenging to cool. Bit of methanol injection will help keep your intake valves cleaner. Has it happened to someone else? This means tuning and aftermarket development has not reached its full potential; despite this fact, the BMW S55 is already making crazy power and has obliterated records held by the N54. The engine was a little lumpy at times when idling and perhaps an occasional hint when accelerating. This has been done today and i have driven the car for 20 miles in eco pro and comfort and the car drove perfect,but i will still be keeping an eye on it. The ML variant makes 335hp while the OL features a staggering 382hp. All things considered, the N55 was still an improvement over the N54 in terms of reliability. So much too learn, so little time. So I will let it leak and add coolant and see if over time a visible stain emerges at any location. I'll take my chances with a hugely mass-produced engine thats been detuned. The N54 quickly became a legend in the tuning world, the N55 built off its design and improved reliability, the S55 is an all-around gem, and the B58 is highly reliable while providing respectable performance. The BMW B58 is a turbocharged straight-six engine, which began production in 2015. The N55 has proven to be a reliable engine but is edged out by the B58. Acnam Infotech, BMW Tuning - BMW Performance & Tuning Guides, News, Videos. Most B58 owners will have a trouble-free ownership experience and spend less on maintenance than if you were driving a N55-powered BMW. what a great site you have! We've seen some VANOS problems with the B58 engine. In 2010, the 335i received the updated N55 engine followed by the B58 in 2016, however, the model was rebranded to the 340i. Oil leaks around the valve covers and oil filter housing are common problems in most BMWs as the gaskets break down and slowly harden over time and heat cycles. Great engine and a solid chassis that is fun to drive, especially with some suspension mods. Car done 150k now, and pipes that I replaced are still right colour, original coolant pump still works OK and I have zero issues with overheating and coolant temp when idle fluctuates at 110 117 C. From what Ive seen at the dyno where some inexperienced or know better then the test schedule requirements technician used pure water for cooling on endurance or long term emission tests, cooling pump seals and joint between shaft and plastic prop would fail first but on my car it was not the case so far, so as usual T&C applies, your milage may vary. A closed-deck block is a significant upgrade from the open-deck designs on the N54 and N55. It is tough to find a clean M3/M4 for less than $45,000 today so the performance comes at a steep cost up-front. Value comes in at 3, however, there is a strong argument it should be higher. Thats really hard to put a number on since it can vary so much. This helps with the length of the connector cable. That being said, there are a lot of bad engines out there! Thanks! **Ranks are as compared between the four turbo, inline 6 engines**. Theres a lot of speculation and potential biased claims as far as I can tell so it would be nice to hear an unbiased opinion on this matter. Its stuff that is pretty cheap to DIY. Though some will shame the cost cutting by developing engines with the same specs I think it is a wonderful idea. Considered my car is stage 1 tuned. Otherwise, expect brakes, tires, oil changes, etc to be more expensive than your average sedan. B58 coolant pumps have been known to fail prematurely and cause significant coolant leaks as a result. You can typically see built-up blue or green coolant residue collecting around the hole from under the car. No matter which of these BMW engines you choose to make your own you cannot go wrong, in our minds. You can say we are somewhat N54 fanatics. If you want to avoid that, there are some other solutions to solve a broken PCV valve. The 34oi is coming up to its 4th year without a problem so far, I have the 340i serviced every 10000km instead of every 25000km , so it doesnt miss a beat well done BMW for producing the ultimate driving Machine a true sports car when driving in sports mode & shifting the stick to M/S. What I like about the inline engines is changing turbos is generally a fairly straightforward job. Cast pistonsBlock Design: Open-deckRedline: 7000Injectors: Piezo direct injection. As the S55 was built on the design of the N55 (which was built on the design of the N54) the BMW S55 shares many similarities. My m140i has now been back to the dealers 3 times in the last 9 days.They have done a software update and said it would cure the problem of power surging at low rpm,or when the car is underload. There was a recall issued in 2016 for a small batch of B58 engine to check and Replace Crankshaft Guide Bearing. Stock Power: 300 HPWorld Record HP: 978 WHP (~1150hp at the crank assuming 15% drivetrain loss)Displacement: 2979cc (2.979L)Turbocharger: Twin turboCompression: 10.2 to 1Bore x Stroke: 84.0mm (3.31) x 89.6mm (3.53)Internals: Forged crank and rods. Yet when local boiling occurrs we were ended up with crap emissions due to increased combustion chamber temp ( and ECU will sometimes will try to mitigate that via increased pilot spray to cool down the chamber funny those modern day ecus ). Haha your last comment seems to be spot on! Stupid technicians, or cheap skates that mix coolant with distilled water cause cooling system boiling point to fall. Ram/Jeep had plans to come out with a turbo powered I6 to replace the 5.7 Hemi, but nothing seems to have come from that. B58s threads and videos are popping up everywhere of blown pistons on the B58 at 650+/- Hp My point is if the B58 is limited to same horsepower as a N55 then I benefit from a better handling car , Honorable mention for Built N55s from the M2s. My '86 CJ-7 had the Inline 6, 258 cu. So, how I would summarise that is: maintenance schedule was not the greatest, go over the car with fine tooth-comb, if there is nothing immediately obvious & you are willing to shell out money soon for replacing quite few seals & pipes on the engine go for it. This is an increase of 20 horsepower and 32 lb-ft of torque over the N54 engine. First, the B58TU1 is available in "ML" (middle output) or "OL" (high output). It seems the coolant loss has now accelerated. Fortunately, BMW learned its lesson on the N54 and focused on improving the reliability of its future turbo engines. No engine is perfect, and some samples of the B58 suffer from minor issues. Notable changes from the N55. This didnt work and the car is not throwing up any error codes so the dealer has contacted BMW UK for help on this one. Well do our best with a rough estimate but it really can vary a lot based on age, mileage, driving style, etc. Over time, the housing and the electronics inside degrade and fail. However, a couple quick notes that are imperative to keep in mind: I love it so far, wish for a manual sometimes but the auto is great most of the time. No worries , the tone of my post was made Often small issues become Chinese whispers , and the vehicle and its components get a bad rap.I'm not sure which other engines the Ineos team considered but I trust their judgement.Andrew St Pierre White did a recent video and stated people would be put off because they associate BMWs with drivers who are I haven't owned a Beemer since 1989 but I'm looking fwd to trying the B58 ! Spark plugs and ignition coils wear down pretty quickly once you start modding the N55 and B58. Enjoy the car and Merry Christmas to you as well! So much so that I'd prefer it over the N55. Bam, 45min to an hour for the whole job. Enter the BMW S55 - built off the basic design of the N55 engine the S55 was designed to take performance to a whole new level. We recommend changing the oil soon after this occurs. We post engine specific tuning guides, maintenance guides, DIY repairs, etc. BMW replaced it under warranty as one would expect. However, you may make it well past without issues. Reliability scores the highest marks compared to the N54, N55, and S55. Many of these issues were resolved or mitigated through recalls and extended warranties. About other part of your comment. Hi Hank, Ive currently been having issues with my M140i. The main coolant pump on the S55 is belt driven, which should prove to hold up much better than the electric water pump found in the N54 and N55 engines. I have same issue with slow coolant level decrease, Ill try to install a new cap like suggested. BMW techs dont seem to know how to resolve this. I couldnt imagine them using it if there was in fact an issue. My question is what are the running costs for them (a ballpark mainly). Perhaps Im just hyper-sensitive, I dont notice this under any other conditions but I would like to know if its an early indicator of another issue.. Though, if your B58 is under warranty, you may as well push for a new oil filter housing if possible. We are hoping to soon add an F80 M3 and F82 M4 GTS. Reliability + performance. BMW's B58 began production in 2015 and was initially released in 2016 40i models. Guessing you are all semi-auto owners.. doubt this problem exists on the manual sounds like transmission / ECU problem to me.. #. ps. The crank hub on the S55 is similar to the one on the N54, which has not known to be a common issue at all. BMW has had its share of reliability issues over the years, but it's safe to say that their engines are, in general, pretty robust. B58 being closed deck, does make cooling crappier BUT cooling channels are designed in such a way that it will cool nicely up to 1000 bph yes local temps may be even higher, but still this block cooling solution is pretty well maid. Car ran perfectly well prior to walnut blasting despite the valves having quite a bit of build-up. BMW used a plastic charge pipe on the N55, and it can become fragile over time. Yes Im in the UK John. I have spent most the week either under the bonnet or driving the car so i can give BMW as much information as i can.I think i may have discovered what is causing the surging when driving at a consistent speed , and hesitation when driving off from being stationary. Im looking for my first sports car and BMWs seem very nice. Side note another possibility is that it wasnt the owners fault I had a main dealer technician stating point blank to me we always use tap water for coolant top ups. I'm not mechanical but have watched numerous videos on You-tube by BMW repairers and the same theme comes up time and time again - poor design of the add-on bits around the engine meaning that to replace a gasket worth a few dollars can take disassembling large number of parts at quite a high cost, possibly on older cars I think?. A tune and bolt-ons will take the B58 into the 400whp+ range; outstanding for a 3.0 L engine, but nothing insane compared to BMW's other inline-6 turbo engines. Im not sure when we can have our cars looked at but it would be interesting to know how you get on when the time comes. Something doesnt add up. Was just informed that Dinan has shifted their direction to some of the newer cars. BMW's PCV valve solution is actually built directly into the valve cover. VANOS is BMW's terminology for VVT, or variable valve timing. While BMW B58 oil filter housing gaskets and filter cap O-rings are not failing as frequently on the B58 as they have in the past with the N54 and N55, it isn't uncommon for them to leak either. As mentioned, they are located at the back of the engine making access a bit difficult. I too have had the coolant loss issue. . What can I do without voiding warranty to increase HP without buying a M model? Well, I have N54 running 550whp on td04s. Our 440i is about 5 months old and has a little over 6000 Km. Hi All As a continuation of the N54 and N55 formulas, the B58 has proven that it is the more dependable engine as a whole. I have had all 3, I had a 535i e60, with the n54. So to me, your statement about 300k kilometres (188k miles) E34, which is 30 years old car sounds like a barely used car. And thats the N54 which is regarded as one of the less reliable BMW engines. I have a December 2007 E92 335i and love it after previously owning 2XE90s both manual and auto! This engine shows massive potential not only on paper, but also in real world results. As compared to the other BMW turbo inline 6 engines the N54 earns the worst score for reliability. Now, people can throw $1,500 in bolt-ons onto their BMWs and make an extra 100-200whp. What are your thoughts and experience with the B58? Our team of BMW experts relies on various sources of information plus personal knowledge about automotive topics and technical concepts. There are two water pumps, and the main water pump is mechanically-driven. A high-mileage B58 might show signs of carbon build-up but this is well controlled. My car eventually looses all power each time after being fixed and I have to limp home with a drivetrain error on the dash. Ok, definitely my thought process as well. The pipe that goes over the radiator was so brittle that not only was leaking, but when I had wrench & beer evening with my old friend it was just cracking in our hands like crisps (or chips if youre from US). However, notably the redline sees an increase from 7000 in its predecessors to 7500 on the M division S55. Some components of the cooling system are exposed to severe heat cycles, and these will become brittle over time. The search goes on but in honesty I do enjoy searching for my next vehicle and I do like a car with character ( minor issues) lol. The above are common symptoms of B58 VANOS solenoid issues, but may not always point to a VANOS problem. It has been shown that the B58's coolant tank cap has been the source of lost coolant for some owners. [/QUOTE]. We may receive a commission for purchases made through these links. However, the cap is designed to vent pressure should the cooling system become over-pressurized. At 28k miles I had a warning light low coolant. The B58 has proven to be the most reliable modern BMW engine, perhaps as reliable as the naturally-aspirated N52. Solenoids are relatively inexpensive and easy to replace. Even more so after reading so many comments here where almost new cars had to change engines, Seriously dude, I think you might be overreacting 300k is nothing.
