EverythingBmwpro is that you?
Philly Accord 😂😂 i really need to start covering other car manufacturers
Simply Car Things 😂😂, nah man you were born to make videos on bimmers! I can’t see you making videos on other brand! But seriously bro, when ever I watch a video, i think your brother is Felix from everythingApplepro! Keep it up bro!
@@phillyaccord5635 hahahaha, i appreciate that brotha. Honestly, i would like to start delving into other car brands in the future but BMW will always be my favorite
Simply Car Things yeah man more diversity means more subs and views!
No, I will unsub on all my accounts+1 if we ain't on the same page my guy. Lol
Love these types of videos that you produce. Keep up the great work man!
Very well done and Informative video. I’ve been looking to learn more about the exact differences between the two engines.
Great job on gathering all that information! I definitely enjoyed watching this video, and also learned some facts from the S55 I didn't know.
thanks man, glad you enjoyed!
Great video Omar! There’s a lot of things about the S55 that I didn’t know
Parker Repp thanks so much Parker! Glad you liked the video man 👌🏼
Thanks for the very insightful video.
Ton of great info, thanks 🏁
Brilliant video Omar very informative as always 😎
glad to hear that, Paul! Thank you as always!
Great video good info !!! Good job bro
Very informative. I really enjoyed the video.
so glad to hear that!
Quite educational. I am looking forward to the 1 and a half hour long version of this topic.
Thank you for watching!
If only the engineers had figured out how to put in a key-way or pin hole into the crankshaft on the S55. Lol
Very informative. Thank you!!!
you’re very welcome!
Wow that's just insane. Good info!
indeed its crazy! Thanks for watching!
Very informative video! Thank you!
Da Ri0 anytime! thanks for watching!
Fantastic video, this is an engine geeks paradise! Had no idea there was that much difference in the engines, makes you appreciate the BMW engineering even more! I’m about to buy an m135i so this is amazing
Did you get the 135 I just bought a m235 and absolutely loving it pushing like 420-450 wheel pretty reliably
Fantastic information well done 👍🏼 💯
kokovq thank you bro 🙏🏼
I have a 2016 F82 M4 Competition and I must say that this video was a real eye opener about my S55 engine! Great engine, great car, great daily driver and an equally great video! Kudos and enjoy your new M4! 👍 🏁🏎
thank you so much man! glad you enjoyed the video!
very informative video loved it!
thanks for watching brotha!
Excellent video dude. Thank you for the education!
PCarDriver87 You’re welcome! thanks for watching!
Great video. It would be good to know which BMW models and in which years came with the N55 and S55 engines.
I have an m4 competition..I can tell you for a fact the s55 rips! Id say reliable too. Ive taken it literally across the country. Zero problems.
Cant wait to own one pretty soon!
justin cupp i have it on the m2 comp, i love it so much!! s55 gang!
I also have an M4 comp. Easily the best car under $100k.
Agreed! bought mine from California and drove it 2100 miles to texas on a straight trip, handled it like a champ!
Not saying it is unreliable, but calling an engine of a 100k$ car reliable just because it can take a 2k mile trip is no real argument.
Excellent video!! Thank you very much. Wow, BMW went all out on the S55.
they really did go all out! thanks for tuning in!
Fantastic video, thank you.
Thank you for this great information
The S55 is a masterpiece. I can’t wait to see what BMW have done with the S58
Great research. Great job 👍
Carlos Lewis No problem, thanks for watching!
Dude, you freakin killed it with this 🤙🏼🤙🏼
Kies Motorsports Thank you so much Bryan! Means a lot coming from you guys 🙏🏼
Very informative! R u planning on making a video about s55 vs s58? On paper they both have rather similar specs but I'd love to know more about what bmw have done to improve the design
Tingkai Shao thank you! I would like to make a video on it, but at the moment there really isn’t a lot of detailed info circulating the S58, so its gona take some time to gather all the research
@@SimplyCarThings Take your time. Looking forward to seeing more quality contents from you!
Good informative video thanks.
Thank you!
Wow the was helpful video about the n55 vs s55 me owning at n54 n55 it seen like the s55 is more fun to drive in the beginning but is going to be more maintenance related once it hits 100k great video 👍
i agree, thank you so much for the feedback!
Thanks for the information, I think I'll go for a N55 for my next BMW as I want to get a M2 I can work on myself, I am not a drifter so I think it will be satisfactory. The S55 sounds overly complicated with more failure points, admittedly it would be cool to have more power but I like to be realistic.
what does being a drifter or not have to do with the engines tho
@@alexandreromao8410 S55 don't get the oil starvation from drifting like the N55 does. You can change the sump to stop this problem. It's not like it's an immediate failure point but it can lead to bearing problems.
@@kishka9886 Oh good to know.
If youre just planning to do a lil power slide here and there , it shouldnt be a problem.
Personally i prefer the n55 aswell.
Great video
Thank you so much! Glad you enjoyed it
Killer info!!
Great vid
Doesnt the n55b in the m2 come with a dual sump to fix the oil starvation issue?
GREAT VIDEO! You have balls! The last time I tried to explain the differences between the S55 and N55 to owners of the N55 I literally got all kinds of profane comments stating I didnt know what I was talking about. People have this belief that you can buy the cheaper alternative and achieve better results than the more expensive model without doing extensive upgrades. Rule of thumb: engineers get paid larger salaries than we do to increase hp in todays cars reliably and the companies charge you for the extra engineering. There are a lot more differences than you explained in the engineering of the entire S55 F80. You are right it would take you an hour to explain them. Lol
Tazmn Wilson indeed it would! both are great platforms but its cool to see the extra development and work put into the M version
@@SimplyCarThings yes both are cars to be proud of.
Hi I see you again lol
Cool vid...but let's see some more content on your m235i build please!!
more videos coming soon!
Thanks man!
anytime!
so you said under G force, the N55 can have problems, will it on my X4 35i, if I drive hard in twisty roads? thanks!
Cool stuff, I had an absolute no idea the S55 had a lot going on
Linda Benton yea it really is quite a piece of kit
S55 is the real deal.
Is the N55 in the 2015 BMW X4 35i reliable? will it have rod bearing problems?
The N55 in the Bmw M2 is a tab bit different than the non-M2 N55. Nice breakdown either way!!!
John Crazy Yes it is! I have a video on my channel breaking down the different variants of N55 engines including the one in the M2 😁 Cheers
Great graphics. Do you know how much can a stock N55 turbo push?
i think the record right now is like a little over 600 hp
Wow that’s helpful
Would love to see a 2022 version of this video comparing B58 vs S55 considering you can find both engines around 30k nowadays. Who takes the cake for reliability, performance and maintenance? 🤔
Hi everybody, just a note- the N55 does not have a forged crankshaft in MOST applications. There are a couple exceptions including the M2, F26 M40i (yes, the X4 did NOT initially use a B58) which have truly forged steel cranks, along with the Alpina variants. The M235i, LCI M135 (and ActiveHybrid 3 if anyone gives a shit or owns one) are oddballs... They have cranks that are made from a stronger steel, rather than the iron in the other N55 variants. if you have a 135, 335, 435, 535, 640, X3, X4, X5, or X6 with an N55, you have a cast crank. This is a common misunderstanding, and I see how easily this info can be confused so I don't fault you for it. It's just worth knowing if you are trying to build these engines, it's what I do for a living. Thanks for reading!
something which I should have mentioned in this video! Thank you for clarifying! I also have some more info regarding this on my N55 variants video which you can find on my channel!
how did you get interested? im sure you started as a kid
Very good engine, if only they had 🤷🏾♂️ design a pin lock system for that crank hub.
Thank you
Whats the normal oil consuption on n54?
What happened to the carbon mirror caps?? Great video though!
Mondo S14 thank you! i’ll explain in a future video why i took them off
One great video! A few things.....1) You really, really did your research. I need to spend more time looking at all those diagrams so I have a better idea of whats going on under these hoods.
2) I own both engines and although I knew the S55 has a better cooling system, I never counted just how many radiators there are. It's crazy! 3) From a maintenance DIY perspective, I just did my VCG on the N55, (very straight forward) and hope to hell I never have fuel delivery or cooling issues with my S55. Lastly, based on how beefed up and protected the S55 is, I'm going to run it hard now and not worry about. And the N55...our relaxing cruiser.
Nice work.
thank you so much! glad to hear you enjoyed the video. And yep, i totally agree with your points regarding both engines. it’s always nice to know more about whats sitting under the hood💪🏼
What abouth alpina b3s/b4s(441ps)...it is based on n55 and propably has another pistons from mahle company...it is very hard to find some info abouth tehnical differences in b3/b4.....you do great job abouth bmw tech info!!!...best regards from europe!
The Alpina b3s and b4s have the s55 engine, the new Version based on the G20 has a b58/s58
Very reliable and durable? How many miles do you have on this? Modern bmws start coughing up oil, ps fluid, water pumps etc at 60k miles.
I have an f80 m3 (pure version) with s55 engine. can honestly say I've never had the gas pedal near full throttle as its just scary fast. have to take it to track to fully explore. It is a race car for the road. Almost nothing beats it
Agreed, that’s why i track my M4 fairly often to just let it loose. It’s a total beast
Just paid for one today 😊
Meanwhile coming from a stage 2 b58 the m4c I drove felt slow lol
So N54 used twin turbo , then N55 went to single turbo ( cause its better ) now we are back to twins ? hope they fixed waste gate rattle issues
I just got a 2012 335i with the n55 and I want to mod it but before going to stage 1, are there things I should do to get it ready for stage 1( im a noob when it comes to tuning rn lol)
josy chargepipe for sure
josy new chargepipe
Charge pipe and Send it!
Has anyone figured a way to put the twins from a s55 to a regular N55?? I'm curious!!
Only the n55 in the M235i has a forged crank/connecting rod, right? The regular like f30 N55's do not?
exactly. only the 235i and m2 models have the n55 with forged crank, the rest has the cast crankshaft
What about M2 N55 variant?
Yeah that cooling system is scary! I complain about servicing the one on my n54, can't imagine that one plus M tax 😭 M2 non comp might be the best of both worlds in that area.
M2 is the best performance with reliability, prior to Competition pack of course
@@alfatech8741 heck yeah, I think if I get another M, that'll be the one 🙂
S55 has same bore and stroke as N55: 84.0mm bore and 89.6mm stroke.
Which Is better s55 or b58 ?
You should compare the S55 with the modified N55 they used on the first model M2.
i like that idea!
@@SimplyCarThings cool...i had a 2017 M2, and I was told it has forged pistons and dry sump lubrication. 2 main differences I know from normal N55.
Great video! I'm more knowledgeable about my F80 M3 engine. Thank you.
Lauren Michaud no problem! thanks for watching!
Would have been nice to compare the N55B30TO vs the S55 rather than the standard N55B30O0
Agreed
BMW actually put a N55 in a M car which was the M2 and its predecessor the 1M had the N54 another M car without the S engine designation. Then you read the forums about people saying the 1M got a N54 for a reason and the 335is. But in stock form the N54 is more capable. The M2 became a true M car to me once they fitted it with a S55. For my ranking of these engines its S58>B58>S55>N54>N55 because reliable power means everything! Only setback is the S55 crankhub if you fixed that you can move it passed the B58.
There are very few crank hub failures.
Absolutely love the visuals! The S55 looks like an absolute nightmare as far as long term reliability goes. But hey, gotta pay to play right?
Actually not really. I was skeptical at first, but so far, some folks have been putting serious miles and multiple track days with little negative effects.
I would just have the m2 as a weekend car
Need to buy a beater daily when purchasing 🤣
#Stillworthittho
Isn't the bore and stroke of both n55 and s55 is the same? I've just searched that aftermarket piston for the s55 is same as the n55.. Just point it out.. Btw I'm sorry if I'm wrong..
You are correct it is the same. That was my mistake in the video
Could you do an engine swap with a 1 series? Replacing the S55 for the N55?
I'm sure it's possible, just would take a lot of work and time to figure that out. A guy swapped an S55 into an E30 not too long ago
Simply Car Things yeah I know it looks amazing!
I'd of been more interested in a S55 vs B58 engines.
It would be s58 vs b58
i owned a mineral white e92 n55 and now i bought a mineral white m235 i love it
Is that supposed to be a joke? The e92 does not use the n55 engine.
BimmerJunkie it’s my understanding that the E9x series code name was exclusively for the V8 M3. Are you saying that version of M3 shared its code name with the non M 3-series? F generation M cars have their exclusive codes (ie: F80/82/83).
@@RB-xv4si Nope. E9x code includes all 3-series built from 06-2013. F generation cars don't share nomenclature, but the E9x's do.
Manat Singh ok. My bad
Might be a bit late, but the statement about the changed stroke + bore of the S55 is not correct. It is exactly the same as in the N55.
So the block, pistons, crank, turbo's, manildfolds, etc are all different. So how the hell are 75% of the components shared??
tryin to figure that one out myself.,
Probably bolts
@@Lu-gm9mx That is funny right there! lmfao
💚💙💛🧡 Great video content 💚💙💛🧡
Thank you so much! glad you enjoyed the video 👌🏼
Hi. Your videos are good I've been following it for a while now. I just wanted to know, is it sure that the N55 has forged connecting rods?
From what I've read, the N54 rods were forged along with the crank, but the n55 is complete cast iron. I may be wrong I'm not claiming you are wrong either, just wanted to confirm my thoughts. Thanks
The N55 is still very strong overall, I've also had a 135i n55 which I've never had doubt on the strength of it.
So the N55 rods are forged throughout pretty much all models. However the N55 crank is only forged in the M235i ans the M2!
I went from M235i to M4.
I honestly don't see a big difference in performance at lower gears. The problem I have on my M4 is that the torque down low is so much that it overwhelms the traction.
Once it's moving though it has more of a pull.
I'm sure on a track or autobahn or something, the M4 would be much more noticeable in power. But practically, on the streets, from what I remember, my little M235i was still really quick.
Love my M4. But I'd like a go in my old M235i again, back to back.
I'm looking into getting an M4 soon actually, stock the power isn't a whole lot especially compared to my tuned m235i, but a tuned M4 with proper suspension upgrades is an absolute monster.
@@SimplyCarThings Mines is stage 1 tuned too. Forgot to mention. I had to turn the boost in 1st, 2nd and 3rd gear down a bit. I like in Scotland and it's cold and wet right now so can't wait for the summer to really try the car out.
Omg! 3 more electric water pumps to replace!!! One is enough! Lol
Steve Polverini or.. 1/3 of the work per pump, so 3x the reliability? Haha
@@dylan-nguyen hmmmm :)
Gotta love brushed motors!
@@adriangutierrez8177... that get hot and give up the ghost at 80-90k miles.
The difference is one is sick and one is
super sick
Alex Rome big facts
You quoted the bore and stroke for the S55 as 89.6 x 80mm this gives 3,026cc. Something wrong there. :)
N55 B & S 84 x 89.6 gives 2979cc ....correct.
Me: it’s just a body kit, new chassis, and some engine upgrades.
Also me now: ohhh yea it cost more for good reason.
100% bro! much more than just a different looking car!
Think I'll just build my n55 😂
Im
@@badexamplepl you’re what?
The bore and stroke you quoted for the s55 isn't correct, they are actually the same as the n55. 84mm bore 89.6mm stroke.
But N55 got many different versions? How does the M2 N55 vs S55 compare?
Raymond Lo ua-cam.com/video/L20EG3bAqG8/v-deo.html
You can watch this video i made! It breaks down all N55 variants, and compares them including the one in the M2
So many components to break down. You'll have plenty of material for your channel
Wow I thought it was only a software upgrade well I was wrong no idea they were so different...
Lol as a 2011 happy n55 owner I love my 335 xdrive msport - holy hell 4 water pumps for the m damn
Hopefully there's no waste gate rattle on these like the n54 has...
Love my m3
So basically 4x the parts that can go wrong on the s55
Mega like it!!!
thank you brotha!
Bore and stroke are exactly the same on S55 and N55.
air to water IC and the UBER cooling system
nuff said
Isnt the s55 twin not turbocharged
Wait why do you have grey mirror caps??
its a m235 thing it comes stock like that
Ray Baldeo Thanks for the information bro👍🏽
Yes why did you swap back omar? My caps i got from you still look great.
I'm sticking to the n55
N54/55 😍 .... n63>s55 for performance?
N63 is trash
The noobs complaining that an s55 will cost more to maintain, are the same dudes that drive around all day with a check engine light in there N54. If you're able to afford this car, you should be able to afford the maintenance.
Facts, well said 😂
Yesss
👍👍
s55 is a track/racing engine n55 is daily/street regular car engine. s55 can withstand more but is also more expensive in repairing/maintaining. Judging the fact that n55 cars are half the price of s55 I am happily owning my 640i with n55 XD
