Why S58 is better? Bigger bore and Less stroke. This engine is less under-squared meaning less stress on cylinder walls. It’s also an advantage for thermal properties. It can also rev higher. Valves are bigger as well. It’s a great combo for racing!
Shorter stroke has disadvantages too... Higher piston speed, more angle forces on the rods etc. Longer stroke is also more efficient, because you can use the combustion stroke much better
Hey man, i've seen your videos for quite a while now. Just wanted to say I appreciate how much dedication you've put into content like this. These videos and your deep-diving is invaluable for those of us that would want to better understand these engines and repair these vehicles. You're easily one of the most important channels to the BMW community.
Its worth noting there are slight differences in the s58 found in F97/F98 to the G80/G82. The crankshaft used in the G8x is different - lighter and optimized for the higher torque & rotational speed. The right engine mount is designed to be more rigid than the left engine mount for the torque increase which should reduce force on the drive system. Pre-production 11/2020 F9X S58s have different cooling. The pre-production F9x S58s are missing an external radiator the G8X have. Also BMW decided to include stone chip protection guards on the coolant radiators.
Yeah technically this was made before the G8x was even out, so tried to weed through some of those specific details. Like the intake integration with the engine cover
They also rotated the spray pattern of the B58TU injectors. They were trying to prevent warping of the upper cylinder. Lower compression ratio, bore and stroke changes, less flowing injectors... reliability and boost were in mind.
Thanks for doing all the work to learn this stuff. I have a 2024 BMW and am a first time owner of a new BMW. I'm wondering about the problems down the road because of direct injection without port. Will there be need valve cleaning down the road? Thanks, Dean in Oregon
I came to the right channel. Your information about s58 is very helpful. Im looking forward to trade in my 2018 q50 for m440i as a daily so i don't want to have worry big issues with the car so i dont have to spend big money as a young adult early 20s
Good info, here. I am thinking of getting a bmw. But I am more concern with RELIABILITY more than luxury. Which X3 do you think is best, currently? I am an old 70yrs. old and would like to drive a bmw that is durable, as it will be the last suv that i will buy, before I go "up yonder".
12:50 Concerning the about estimated power output of the S58 and you assuming it's capable of doing about 30% more power with the injectors, I want to tell you, you are pretty much right! There is a german tuner called Benny from "BK Performance" and about 4 years ago when the S58 came out with the X3M and X4M models, he already got his hands on the X3M and tested it's "limits", he ended up at 757hp with everything stock besides installing a different Downpipe (and what I'm not sure about is, he might have changed his Intercooler to a Wagner one, I don' remember exactly no more), BUT what I know is, he definitely didn't change anything else than I mentioned. The car was also featured on quiet a few other TH-cam channels like "AutoTopNL", he could have went for slightly more power as well but he wanted to run a safe setup. He even drove the X3M with that power with 310km/h+ !GPS measured! on the Autobahn :D
Idk imo the s58 connecting rod look stronger at least on the bottom side where the bearing goes you can tell it’s beefier and the the way the profile is it’s designed better but I agree it’s thinner
Love your work! Since a clean used F80 is 10k cheaper then a G80. Which one do you prefer? Can you please make a comparison video? Keep up the great work !
I have been driving the F8X for almost 6 years. I was the biggest F82 fanboy. Just switched to the G82 Comp RWD, and I have yet to look back. These cars are simply a different level!
thinking along the same concept as s58 head on a b58.... would it be possible to explore s58 head on S55 because some of the systems exist in s55 to support it? or are there simply too many architectural differences in block/mating surface to be viable?
Hello Kern, I just came across your channel and I am very grateful what you’re sharing with us. Thank you! I recently bought a 2024 BMW M440i Xdrive coupe and running 94 octanes pump gas on JB4 map 3. I also installed a VRSF 200 cell catted down pipe. Do you think I will be okay to keep the stock fuel pump as well as injectors if I upgrade to a Vargas GC mid turbo? Also, if the gas consumption would suffer with normal driving habits after the upgrade? What do you think about my approach? Warm regards. Alfred. July 9, 2024
Hey so I have a question, I’m afraid that I might hurt my engine. Im eventually going to go down pipe tune, but right now I’m stock and I needed a oil change. So I used 5w-30 for thicker oil instead of the recommended 5w-20. I’m afraid it will hurt my engine since I’m stock as of now? Please give me some answers cause I’m worried.👍
I don’t think it will have any affects on it but I just want to make sure nothing will happen since I’m not modded yet. I only got 5w-30 oil mainly because I’m going full bolt on soon
Hi sorry to ask this but its a oil Q I HAVE A 2023 M3 COMP XDRIVE BROOKLYN GREY STOCK AND STAYING STOCK FOR NOW IN THE UK . THE OIL REC over hear IS 0W30 THE Q IS IS THIS JUST FOR THE OPF FILTER COZ I WANT TO LOOK AFTER MY ENGINE CAN ANY ONE GIVE ME SOME ADVICE PLEASE. PROFILE PHOTO OF A45S PLUS OIL REC IS 0W20 416HP
Hahaha lol at the intro "the b58 is you" 😂😂😂 what would be nice is a comparison of bang for buck performance. A 30k b58 gen 1 with 30k in mods vs a s58 with a tune for example. All tough a M car will be sharper from factory. Many of yall only seem to drive in a straight line for a couple of meters. So that doesn't matter as well. 😂😂😂 Keep it up Kevin. 💪🏻
I have a g87 m2 2023. I like the car alot, but with only 9000 miles on it I blew the motor with only an Areeve piggyback tune dinan cold air kit and IRL midpipe. Very disheartening since BMW will not cover it so I had to eat the cost. Not sure what went wrong but not to happy right now.
Kevin, thanks as always. Are the S58 injectors plug and play in a Supra/Gen 2 or do the seals need to be replaced? I'm looking to do this and have heard both...TIA
Lol 3 pick ups in the pan is more things togo wrong. And weaker piston rods is bad news. Online 6 weaknes through out time has been weak piston rods. The thicker the better. Otherwise besides the amount of plastic it seems solid.
Lol why would anyone be worried about an engine that’s not even in the 7s… I think you meant S58 Is you Gen2B58 is the one your girlfriend tells you not to worry about 😂😂

Watch that video, it shows a very good comparison of S55/S58/B58 rods and bearings and S58 parts are not getting a good rating there. You can switch on English automatic translation: th-cam.com/video/WA-k3p8zM2M/w-d-xo.html
Translation is not good I see, basically S58 bearings are already slighly worn after 10000 km while B58 is even with 100000 or 200000 km still like new. So they say S58 bearings will become a problem like S65, so after like 60000 to 80000 km you have to change them. Pistons from B58 are ok but not the best. S58 pistons are better. B58 rods are the best, S58 is not as strong.
I'm so fed up with these so called incredible bmw engines Who cares about all of these accolades, when they start burning oil at 50-70k miles and start having major issues under 100k miles.?.. Yes, S58 is great while you're leasing your X6M.. Big deal
X6m doesn’t have an s58 first of all second of all the b58 and s58 haven’t had any oil burning issues so far and a lot have made it past 100k miles no issues
And we're fed up with ignorant people like you who don't even know what cars carry these engines, let alone know nothing about the engines themselves. Nice try... 🤡

I loved the video, only thing I’m unsure about is, the rod bearings do actually have coating on the top bearings for S58 and not the bottom ones.

the cylinder head is not 3d printed. the inlet for the casting is 3d printed.
Nice work and incredible detail
great insight! would love to see a deep dive on why the S63TU is good
2:34 - it's only the sand cores for the head casting that are 3D printed.
I'd love a breakdown of an N63TU2. And compare it to an N63 OG to see how its different.

Idk imo the s58 connecting rod look stronger at least on the bottom side where the bearing goes you can tell it’s beefier and the the way the profile is it’s designed better but I agree it’s thinner
No problems here with my s58. Just lots of giggling.

If you blow your s58 how much is a new long block replacement? I can’t find it anywhere. Without calling a dealer.
