Finally bought my b58 after a year and a half of research and seeing what’s best for me. Videos like this helped me make an informed purchase and a smart one 👏you’re a dog kern you helped so much, hats off
I don’t even have a B58, my s58 m3C is my first BMW and when I stumbled on your Channel it gave me so much insight on the tuning world of bmws and I thank you for that. My 2022 m3 is my first BMW and all your videos help me understand a lot about aftermarket world of bmws. Now do a video like this with S58 lol. Keep up the great work!
Just know you got the best engine with upgraded suspension with 2022 x3mc to make up to 800HP. Easily with a few upgrades & stage 1&2 custom tune. Don’t take shortcuts. Enjoy your ride.
I had read this : forged pistons , IIRC , the thermal conduction of forged part makes them to expand or shrink more than non forged so with forged pistons you HAVE to put your engine on good temp before "using" it they will expand with temp . or they will scratch the cylinders if used too cold ( because shrinked ) sorry for my english .
I know "the internet" always says that "forged pistons expand more than cast pistons", but it's not actually that simple. Most modern cast pistons use hypereutectic alloys that contains a lot of silicon, high silicon alloys are harder and expand less and can run with tighter clearances, and are quieter when cold; cast hypereutectic alloys can't deal with as much detonation as a forged, low-silicon alloy like 2628 and when hypereutectic gets damaged it tends to explode into a million tiny pieces. Forged pistons tend to come in two alloys: 2618 -a high thermal expansion, low silicon content alloy that's can flex more before breaking and has the most detonation resistance and requires more piston-to-wall clearances. 4023 -a low thermal expansion, high silicon content alloy that gives you much more strength than a hypereutectic cast piston and also provides the benefits of a low thermal expansion alloy. (It's really the aluminum alloy that determines whether the piston expands a lot or a little as it heats, and there are FORGED pistons that are both high thermal expansion and low thermal expansion alloys.)
🪰😆. Great explanation of the cylinder and reasoning for the cylinder shape. Interesting regarding the two front auxiliary coolers. On my m140i pre PPF/OPF I only have the one and that plumbs into the charge cooling/air conditioning circuit I believe
So being the b58 comes with forged internals the pistons they should be 2618 alloy with a high aluminum content, if they are 4032 alloy they have a lower aluminum content, a higher silicone content but they can have smaller piston to wall clearances. If they are cast they are not as strong and more susceptible to damage if any detonation event happens.
Speaking from previous experience, if you don’t have rock guards for the Inter coolers / auxiliary radiators. I recommend installing them or doing your own DIY guards. There is a rock out there…. Waiting….
This video is great because there is so much to talk about when it comes to positives of the B58. Instead of fumbling over my words, I can send this video to my VAG fanboy buddies to convince them to switch to BMW
On B58 cracked ring lands: any evidence on whether this tends to be detonation due to a bad tune / not-enough-octane for the tune vs. heat causes the rings to but / not-enough-gap with big boost? (Curious at what point someone should crack into the bottom end and gap the rings, mostly...)
WOW Thats Detailed review Thank you for your work!! Im Glad im able To support you On Patreon and im Happy i own a B58 Love it ❤❤🎉 i learned a lot from you !! Tuning wise , What to look out for , how to keep car healthy etc 🙏🤙🏼
@Kern417 Any idea what materials and thickness the B58 stock piston rings are using? (I've never looked into what kind of ring materials need to be used with a Nikasil coated cylinder and I'm just curious.)
Like B58… Love the S58/LCI in 2022 or newer in the x3mC or X5mC as best motor right now to build off of. X3mc is 660 lbs light x5mc. convinced the S58 is bulletproof…
Hi Kern. I'm thinking buying a X3 M40i soon. What model years would you recommend? Been looking at only 2018 to 2019 years prices are ok with mileage below 70K. I like the exhaust in those years they pop nice in sport mode. Thanks
Hi I’m a really big fan of your channel, I think you’re the most informative BMW guy on the internet. I’ve seen you on the forums and then unknowingly seen you on TH-cam and finally made the connection, I was impressed by you in 2 separate areas, both of which were impressive on their own, combined? You’re the guy. I’m nowhere near as knowledgeable or as capable as you when it comes to working on these cars but I have a question for you, I’m someone that has OEM Anxiety, for example if I swap something that on paper should be a massive upgrade over the OEM part I for some reason have anxiety that it’s going to cause a problem. I love all the modern B58 cars/suvs, if I wanted to replace the OEM charge cooler manifold on a modern B58 with an aftermarket charge cooler manifold, is there any downside whatsoever to doing that? Is there any potential hazards or unforeseen complications? Or is it better across the board no question? Looking at do88, CSF, wagner manifolds. Do you have any preference? Will likely match the intercooler, trans oil cooler, and auxiliary radiators, to whichever manifold I choose.
Have you changed your oil pump, or had any issues??, I seen a disturbing article about pre 2020 b58 having a common oil pump failure 😢 but other than this new info, I love this thing 😅
Hey Kern, I have my car ready to dyno tune this week with the mods listed below and I want to have an idea of how much HP I should be looking at when it's done. My tuner is good, but I want to make sure I'm getting what I'm supposed to lol List of mods: Intake with turbo inlet Catless downpipe Active Autowerke exhaust Charge pipe Dinan spark plug coils X-hp transmission tune stage 2 Fuel-it flex fuel kit (I'll be tuning with E40) Tuning platform will be ECUtek
depends what car you have and which version of the b58, assuming you dont have any fueling upgrades you should be around 480-550, keep your tq under 600 to be safe and not slip 4th gear (trans limit is 700), dont tune 5th and 6th for power, try to get your powerband in 1st to 4th gear, 5th and 6th dont really hold much power, also be careful about raising your line pressures in XHP, i personally would stay on stage 2 MAX, never hit stage 3 unless you need it for a single drag run, let me know if you have more questions.
Great video providing a lot if insight! Hoping someone can help me out with the following; i have a M140i, stage2+ / stock turbo, all necessary bolt-on mods done, ran 50.000 km, and have been experiencing some power loss when going WOT. Didn't get any CEL's. Did several checks and ran logs; the cause appeared to be advanced ignition timing on cylinder 1, but no knocking. Changed the sparkplug, coilpack and injector, but no results. Further checked the cylinder with boroscope, all looked good. Almost no carbon build up on the valves or piston, no visible damage to cylinder walls. Compression test and leakdown test values were all good. They can't find the cause of the advanced ignition timing, so we've come to the point to taking the engine out and pull the piston of cylinder 1 to check. Anyone has any ideas what to check, or maybe some direction to look for before we do so? Appreciate your feedback.
I got a 22 m240i with a b58b30b engine, engine got water in it, block is toast, could a b58b30c block work and I swap the head onto it from my b58b30b?
Great video. I don't think people understand just how amazing the cooling setup is on these cars. Being able to run warmer coolant temps at highway cruise and then cooler coolant temps when going WOT for a while is a magical thing. I REALLY wish someone made a retrofit that would use the BMW electronic thermostats in an old engine and a simple controller for them. My one "wonder" on the B58 Gen2 engines cooling is whether the electric water pump that controls the intercooler circuit is really up to the task when you do things like install a 3 pass CSF heat exchanger for the intercooler circuit. (3 pass heat exchangers can dramatically slow the coolant flow rate vs. a single pass design and I really wish I knew the limitations of the stock pump and if there were any aftermarket pumps that could boost the flow rate.)
I think it’s more about longevity of the car or SUV in the long-term. If the BMW X5/X7 can last relatively problem free for 150,000 miles that would definitely be a win.
Any suggestions on why my B58 feels so powerful and smooth but no smoke no leaks and consumes a quart of oil ever 3-4k miles? (It’s a BMW is not an answer commenters lol)
@@pawelludew291it’s Gas stock 91 octane Toyota and BMW both use 0w20 in the B58 as far as I’ve seen. It drinks a quart every 2000-2500 miles but Toyotas consumption test is 1000 miles
I got a weird problem, if anyone could help. I’m running a catless downpipe, mst intake and everything else stock, i’ve started to noticed that after doing a small pull and letting of the gas, sometimes white/ish smoke comes out of the exhaust but only sometimes, coolant level looks okay although i do top it off every other week. any ideas of what i could start testing? or could it be simply the downpipe.

When he gets a M with the S58 I think more content on that part will come😂
Just have to wait now

The B58 just might be the Epitome of Inline 6 engine design. I wonder if anything else would top it ever
I don't believe so. Gen 3 is having major issues
Only thing holding it back is the electronics and plastic, but I guess that applies to a good portion of modern engines
3jz would but as of right now its the best I6 ever created
I had read this :

Yes and will have larger p/w clearance so until warmed up they will be a little noisy.

Right, I think the second one was only available on the other side of the front for the PPF version. Since the PPF is getting hotter.
So being the b58 comes with forged internals the pistons they should be 2618 alloy with a high aluminum content, if they are 4032 alloy they have a lower aluminum content, a higher silicone content but they can have smaller piston to wall clearances. If they are cast they are not as strong and more susceptible to damage if any detonation event happens.
Excellent to know. I did finance my car because I could finally afford something nice. Nice knowing I made an awesome choice on a 340i
I just bought myself an 440i and i need to ask for your exhaust setup, 0:49. that sounded amazing!
THANKS for all you do, I learn something new ALL the time!!

What years are the most reliable B58 engines, and does not have the oil pump issue?
@Kern417 Any idea what materials and thickness the B58 stock piston rings are using? (I've never looked into what kind of ring materials need to be used with a Nikasil coated cylinder and I'm just curious.)
Off topic question. Is it possible to manual swap the 340i and what could be the options?

Amazing video. I wish you could do this for S58 as well.
can u answer y there is no one doing upgraded turbos on the g42 m240 yet?
I been lookin on bimmer post for the longest. It is even hard to find people doing dme unlocks on g42 as well. More people seem to get the g20

I wonder if the block and head are investment cast? 🤔
Came to get knowledge on why the b58 is the goat, stayed for the sick beat boxing 😎
What years and model #'s is the 2 port B58? The post 2020 motors also have higher fuel pump capability too right?
Have you changed your oil pump, or had any issues??, I seen a disturbing article about pre 2020 b58 having a common oil pump failure 😢 but other than this new info, I love this thing 😅
Forged internals have to be the biggest marketing trend word right after psi.
Are you dumb?
Question: Does having such an intricate cooling system explain the B58's higher than normal coolant consumption?
I have a 2021 BMW m440i. What’s the best way to go about unlocking the ECU so I can tune with mhd ?

Ok so… One big thing I get from this upload is:
cool engine = better longevity?
