BMW B58TU2: A closer look at the new engine variant - Part 1
HTML-код
- Опубликовано: 7 сен 2024
- Welcome back! The 3rd generation B58, the B58TU2 is here! Unlike the 1st generation B58 and 2nd gen B58TU1 there is very limited detailed information about the B58TU2. This is where I come in, I have made this video to dig deeper and have a closer look at the B58TU2, BMW designation B58B30M2. Although the B58TU1 comes in two variants (the B58B30B aka B58B30O1 and the B58B30C aka B58B30M1), I will be comparing the B58B30M2 to the less powerful B58B30M1. This is only Part 1, with plenty of material for a second part. If there is demand for Part 2 I will certainly make it! Hope you guys enjoy the video, and let me know in the comments below your thoughts and feedback.

Great video, waiting for part 2
Thank you! I was about to get a 2024 330e but I see TU2 is coming to the 2025 MY. Having port injection added is more than enough for me to wait, don't want to deal with carbon cleaning.
Thank you! Looking forward for part 2
I got all excited and went to check on the 2023 M240i to see if I had the TU2 with port injection, but of course that wasn't the case. Oh well, can't have it all. Thanks for the excellent video.
Thank you! And your 2023 M240i is a hell of a car!
Can you please release another comprehensive pt 2 video ? Also could you go further in depth about the lack of alternator
Please keep making this sort of video. Also would be great if you could do the same for N54 vs N55 and then the different versions of the N55
This! I keep reading so much different things about the N55 engines, between the PWG N55s in the E9X chassis, the EWG N55s in the F30 335i which are supposedly different from the N55s in the M235i (forged crank etc?). And then theres the M2 N55 with a supposed closed deck block which has a complete cloud of mystery around it. I'd love to see all the different N55 models cleared up.
@pranavk8293 Search for Simply Car Things N55 engine variants. He did a pretty good breakdown video of the differences on the variants of the N55. Also with your comment you are mostly spot on except there were a few F chassis cars that came with the PWG still 2012, 2013 & 2014 models. Also I am pretty certain the M2 still had a open deck. But the N55 in the M2 was definitely peak N55 and the most durable one of them all.
@@carcrazyguysa4059ALL N55 were opendeck!
@@tommerlin6579 Whats your source?
Love all the comparisons. I was hoping i would be able easily swap out the direct injection on my tu1 to the tu2 but that looks like it's not going to be a easy as i hoped. I'm a little surprised they didn't go dual injection.
Simply Thank You! And waiting for second part.
Thank you for this awaited content. (Liked prior to watch)
You are welcome! :)
Great video and looking for ward to Part II. Def helps me navigate my '23 m340i which (I think) is the B58B30 (D?) with the mild-hyb. I've tuned M44 and M10 engines so this one is WILD!
Thank you, you have a B58B30B (aka B58B30O1) which is also known as B58D under the Illustrated Parts Catalogue.
The subject is probably under constant evolving. What is B58D? and where does it fit into the story?
B58B30O1 (technical manual) = B58B30B (engraved on engine) = B58D (IPC e.g RealOEM)
So B58D means the second generation B58 (aka B58TU1) with 382hp (i.e. 6-port version).
@@NoBrainerTalkthanks, I have this engine too. I looked under the hood today and have the 6 port. The M1 have the 2 port, right?
@@janh9030 Yes, the M1 is a 2-port.
@@NoBrainerTalkthanks for good explanation video👍🏼 do you know the of the problems with the plastic oil pumps of some first M340i?
@@janh9030 Hi there, I do not have details for the topic you mention.
This b58tu2 engine goes into the the 40i models. Im pretty sure the m40i models, or soon the m50i models will have even different components.
Yes, the B58TU2 is expected to feature in various upcoming refreshed / LCI BMW models.
Thank you for making these highly interesting comprehensive videos. I really enjoy watching them.
Do you think BMW will also make a B5830O2?
I honestly don't know (there are always rumours) but I believe with current trends they might divert their efforts to a more performance oriented hybrid drivetrain (using a version of B58B30M2) rather than make a B58B30O2. But I am just guessing.
Love this type of comparison. More pls, more🎉🎉🎉
Good Job very interesting ! When will you post the second part please ?
Hi pal,great insight and much appreciated.
I believe BMW lowered the compression ratio to 10.5-1 on the B58TU though
Hi there, the compression ratio for the two B58TU1 variants is different: The B58B30M1 is 11.0:1 whereas the compression ratio of the B58B30O1 is 10.2:1. In this video I was only comparing the B58B30M1 to the B58B30M2.
@@NoBrainerTalk well I’ve learnt something new,every days a school day!
Again- your doing a great job,keep it up mate
6:55 just notice how beefy structurally the new block looks. I bet it can handle way more power now.
Doubt it. BMW wouldn’t update it to handle more power. If you want a inline 6 that’s over engineered, go with the n54
This is a better engine overall but n54 can handle more power. Well I guess we will see
@@johnnychimpo7539 The B58 has a closed-deck block. By this nature alone, B58 is significantly more over-engineered structurally than the open-deck N54 and can handle more power in stock form. N54 is a great engine too, and N54-engined cars are very affordable now and making them very popular for mods and projects and have more aftermarket support, hence you see more high power builds with N54. But I am simply pointing out your statement of referring to a N54 being more over-engineered and can handle more power versus the B58 is not correct when they are in stock form.
Are all tu2 2 port exhaust heads?
Early b58 are all 6 port and b58s found in the later cars can be either 2 or 6 port depending on the model they are found in.
Yes all TU2 are currently 2 port.
Brilliant video mate
Part 2 please 😅
@7:17 the block on left noted as “B58TU1” is the original B58 as the timing chain shown to have the bulge of the intermediate drive sprocket.
Actually, you are correct, RealOEM / the Illustrated parts catalogue for the B58TU continues to show the 1st gen B58 illustration under the short engine section. I thought it would be OK considering the points I was making. But you are certainly very observant.
Thank you for the info
Great video 🤘💯
Well done 👏🏻
Ask yourself why?
Because it's a bad ending and they're changing it quickly.
I'm glad I kept my N52.
Update for 2024/25? B58's got a power increase from 335 to 375 and wondering if they're still using the old 2 port head on 375hp 2025 X5.
Yes they are.
Fun drinking game. Take a shot every time he says B58.
Don't drive afterwards... :)
I'd be B58'uked
I have the 2019 440i Gran Coupe 1st Gen B58 with MPPSK from factory....thinking of upgrading to TU HPFFP. Can i have your thoughts/opinion about this if this is a safe mod?
Hi, the B58TU HPFP has been installed by a very large number of 1st gen B58 owners with generally no issues reported. It is a safe mod, especially considering the mod is combined with a more aggressive tune. However, in your case I don't know if you plan to replace the MPPSK, which comprises of BMW's 360hp tune as well as upgraded exhaust, as otherwise you would see little benefit from the B58TU fuel pump. You would need a high flow downpipe as well as the B58TU fuel pump in order to install a stage 2+ or stage 2.5 tune.
Thank you very much for your insights and for taking the time to reply. I really enjoy following your posts
Would you happen to know if the B58TU2 is in the 2023 BMW M340i ? Thanks
Did a bit a research from what i gathered last week, and did a vin check as i remembered, the 2024 BMW M340i has the B58D ???
@@the404man Hi, the 2023 M340i does not have the B58TU2, the current M340i does not have the B58TU2, but the B58TU2 may feature in the M340i later on possibly during a further refresh (e.g. LCI-2) of the G20.
I just purchased a low kl 2020 BMW 540 which has the B58B30M1 engine. In your opinion is this a superior engine to the original as I plan on doing some modest modifications (downpipe / tune / intake). I am a bit concerned that BMW hasn't used the B58B30M1 in many performance cars and quickly went to the TU2 which has more horsepower. I suppose the supra used the B58B30M1 for longer which is perhaps a good sign? Thanks
Personally I feel the 1st gen is the best B58 engine, but the B58B30M1 is a very good platform for modest modifications.
fantastic, thank you
still a 2 port? guess i don't feel as bad with my TUsupra. I wonder if i we can clone and see if the DME was compatible with the TU for port injection without using a external controller.
Hehehe, the B58TU2 DME will only work with very specific hardware, but hey who knows, it might work!
Really informative
Where is part 2?
I am drowning at work, haven't had a chance to make any videos at all. There will be new videos in 2024.
@@NoBrainerTalkGreat! Sorry about work!
@@kurtm54 Don't be! It pays the bills! :)
What type of engine is in the X5 50e? Thanks! Great video.
That's a good question, I'm not 100% sure to be honest. It should be a detuned B58B30M2 generating roughly 308hp coupled with Hybrid Synchronous motor generating roughly 190hp.
@@NoBrainerTalk It would make sense, I will have the car at home in two weeks time so I will check the registration list to find the engine code. I am super happy that BMW has added port injection to get rid of the carbon buildup.
@@marcelmatzenauer6352 I am looking forward to your update. :)
@@NoBrainerTalk I have found out that the engine model is B58B30S. Is there a way to find out if it had both types of injection ie. It would be variant of TU2? Thanks!
@@marcelmatzenauer6352 Hi, do you have the car yet? You can have a look at the engine itself. It will be quite clear if it's a B58TU2 through the intercooler (and you can check the area between the engine block and intercooler for the new injectors). You can also send me various photos by email and I can have a look: nobrainertalk@gmail.com
on the mild hybrid assist which replaces the alternator, we know it is a 48 volt system, but what kind of amps or total wattage do they get into and out of that thing? Dealers seem clueless.
Yes, dealers are not very technically minded, I agree. I don't know much about the 48V system, but I do know the batteries (1st gen) are 10Ah 440Wh 44V (if it helps).
I read the 48V alternator can output up to 250A for short durations, on the mild hybrid tu1 engines. there is a separate power control module to convert 48v to 12v
@@780brando great info. So, is the drive motor part then doing 250 x 48 = 12,000 watts = 16 hp? Presumably, it dumps power into the house battery on regen, making it avail for launch assist and acceleration later? How long do these 12v house batts last now?
@@gendaminoru3195 Yes the alternator is aka "starter motor/generator" on the models with mild hybrid. the SMG charges the 48V lithium battery directly. when coasting (depends on drive mode) there is slight regen, regen then increases with braking. there is a display in the gauges showing regen, but not assist. Not sure on the life of the 48V lithium battery
@@780brando Yes on the test drive I saw that display, but was wondering if there's an indication of assist - maybe a code or programmable dash or some secondary readout like we used on the old E31's pixel display. Anyway I will figure it all out next month after delivery. What's the word on ECU/EML reprogramming by Dinan or others on new cars? Warranty void?
Why is this motor only 2 port for exuast manifold
Quite possibly for efficiency, i.e. emissions. It would help the engine warm up faster.
So the B58 TU2 has port injection only or has dual injection system with GDI and PORT?
Thank's a lot and congratulations for your channel
BimmerN53
Thank you! The TU2 has both, low pressure port injection and high pressure direct injection.

@@genderlessyoutubefanperson Hey there, it is a B58B30O1 (the 6-port version of the B58TU1).
So is the m340i b58tu still better I'm assuming for power mods?
Hi there, in terms of tuning and mods, we are back to square 1 with the B58TU2. The various aftermarket parts companies will have to develop brand new hardware upgrades, but to take advantage of those, tuning is required. The issue is that the DME is a new standard and is back to being locked. So for customisation and tuning, there's no real options for the B58TU2 until the ECU can be unlocked. Tuning boxes are being developed (e.g. from JB4) but that is about the only option for some time. Testing has shown great potential for the stock hardware (so tuning boxes alone, and later on stage 1 tuning, can accomplish what previously required upgrading hardware). As the stock hardware seems to have alot more potential than 374hp, we might expect to see higher engine outputs of the B58TU2 in a package like MPPSK. For the time being the B58TU1 can be readily upgraded but the B58TU2 can't.
Where is part two it’s been eight months my guy
I know, I know. I blinked and months went by...
Is the oil pump plastic again?
was it plastic on previous B58 gens? I don't think so...
@@NoBrainerTalk it is in earlier versions I think 2020 and older. Maybe not everything is plastic but it had plastic components and failed with oil pressure too low message. Making everything cheaper I wonder if they 'improved' oil pump as well?
@@hrsjohnny Hi, although I would agree the B58 has steadily become more complex, I wouldn't agree it became cheaper made. It was beefed up significantly from the start, and after gaining experience I would agree that BMW might have adjusted some of the specs, but the engine is overall quite well engineered and robust. Remember this is not a full fat M-Engine meant for track use, it is meant for road use and as a road car engine, is engineered well above what it is intended for. Not saying there aren't any problems, additional complexity and new features inherently bring risks and complications, but I would say BMW is trying to keep standards high with the B58.
@@NoBrainerTalk sure it's a power house and making 400hp and more reliably. All I am saying is that so much plastic in the engine is not for longevity. It's not built to last, plastic oil filter housing will no way last 200k miles.
@@hrsjohnny It's certainly a valid concern if the plastic will last, but metal corrodes and rusts (which plastic does not) so I guess there are pros and cons. Ask me again in 10 years. :)
are we getting a part 2?
Yes :)
Part 2 soon ?
I am recording new videos in my spare time, might release them all in a few weeks... no promises... 🤣🤣
Which gen B58 is the 2024 m340i?
It is currently 2nd gen, and some sources indicate M340i with 3rd gen will feature later on, possibly later this year.
@@NoBrainerTalk I see. Thanks!
Do the newer Supras come with the TU2?
No.
So what gen is my 2020 440i ?
Definitely not 3rd gen. Most likely 2nd gen. Check out this video (at the time there were only 2 generations and 3 variants):
ruclips.net/video/lwFH-5Pgv7o/видео.html
You should be able to tell which one you have (1st gen vs 2nd gen).
Should had never been called b58tu2.
Interesting, why is that? :)
Too complex????
