BMW S55: Everything You Need to Know 

If you guys enjoyed the video, please SMASH THAT LIKE BUTTON. It helps the channel out a huge amount and helps RU-vid put the video in front of more people. Thanks for watching 😬

I have an F82 M4 and I love it! Great power and just feels like a well built car. Great breakdown of the S55!

Crank hub definitely a hustle....I have 125,000 plus miles and haven't had any crank hub issues....fuel pump and injectors did go out at 110k....have been on a stage 2 tune and 100octane tune for yrs

was doing all those basic mods on my old grand nationals 20 years ago to make butt loads of power. love turbos!

Hi Bryce , Stephen Shippy . Just wanted to say hi and really enjoyed your video. Well done! We just sold Logan’s m4 crazy fast!!! Keep up the good work.

Great keep it going!!!

me and my friend learned a lot about the s55!

Well done video. As a performance shop that does a ton of bmw work, we normally recommend building the engine if you plan to go past 700ish whp/torque to be on the safe side. It normally takes e85 or meth in combination with a hybrid turbo to get there. Also, while spun crank hubs are less common on unmodified cars, the more power you push the more risk you take. If you are staying stock, probably can keep the stock crank hub.

Regarding the different "versions" of the S55, they all use the same long block and accessories. Other than the use of water injection in the M4 GTS, the difference between them is the tune.

Ill like to see a video about the 4.8l Vortec

That us actually pretty amazing in terms of power figures. Just imagining putting a s54 crank in it and forged internals and a bigger turbo(s) you'd have basically a 2jz.

PLZ do the VR30DETT!!! I need the details!!

dank video

love the facts and knowledge please do one of the G80 M3 engine, and more about ZF8 and DCT : )

Great video though!

Coloradon5x ayeeee

E36 m3 was predominantly the s52 96-99 a 3.2 OBD2. The s50 was only available in america in 1995 and was a 3.0 obd1.

Great video, side note music is a little loud

Fantastic information. I got a M3 2016 a it's amazing powerful. But in 53,000 miles have problem with the diferencial. The sound is horrible like damage wheels bearing. Can someone give me some information about it. Thank you!

Spinning of the crank hub comes from mashing the throttle in high gear (5,6,7) and having the kick down feature activate, jumping you to a lower gear (2,3,4). Just avoid this and you’ll be fine (terrible for the car anyways).

so no connecting rod bearings and valve lash shims? I am keen on a manual one for sale near me haha

Hell 2 the Yeah

Hi there nice vid by the way. I just want to ask and since I have a 2021 M2 competition, I decided to change the downpipes, the pipes going towards the back is from eisennman race with no exhaust just a straight pipe with no blockage whatsoever, then I change charge pipes, the crank hub and have the ECU tuned, thats it. Now my question is do I need to change my OEM intercooler to a CSF or any aftermarket dual pass charge air cooler? and I dont track this car but just drive it daily and drive it spiritedly and fast. Hope to hear from you the soonest.

You mentioned crabkhub issue was a pre 2016 production, how can I verify that information? So, 2019 a d 2020 S55 have a different crabkhub?

I love my f80 by far the best car ive iwned. I got the crankhub fixed and aftermarket charge cooler and all breathing and exhaust

Also the n55 has cast internals and the s55 has forged internals and mahle pistons and thats a huge difference when driving these in race applications!!

I have a stock 2018 M2C with 30k miles on it. Hoping there aren’t any issues that will arise, especially with that crank hub he mentioned 🤞🏻

U mention they put turbos to keep up with modem cars and u have a vw gti on the list lol not hard to keep up with a gti

I think that there wasn’t a 360hp version of the S55. The early M2 used the N55 engine and not the S55. It’s when the M2 competition came along with S55 that they started to produce 410 hp. I’m pretty sure about the engines that were used in M2 and M2 competition, but not sure about the power outputs. Maybe they are slightly less or more.

My car dynoed 734whp/676wtq with pure turbos so yeah s55 ftw but this is like the absolute limit you can do on these motors. Any more you are risking the fact you will blow your motor.

Crankhub-gate should be a term. Easy money for these shops.

so, the later N55s have the same rod bearings from the s55. right? 2015 n55? does this mean they will not fail??

"other things" includes leaking top mount intercooler into your cylinders. And by that I mean it can literally seize your engine. I came this close to selling the car 2 months after I bought it because it would always stutter at high speeds and then eventually got to the point where I couldn't drive it at all. I took it to BMW for them to do their stupid fucking multipoint inspection. They told me "all good." Clearly it wasn't. They said, "change cylinders 3 & 6 plugs and coils for $1500." Told them to shove it and give me back my car. The plugs were brand new. Long story short, I wasn't convinced it had anything to do electronically. I then did a ton of research to find out the top mount intercooler will leak directly into your cylinders and cause serious damage. When I finally almost wore myself out, I worked up the nerve to buy a brand new intercooler online and install it as a "hail mary." I even told my family if this doesn't work, i'm done with the car. As I was installing it, there was about 16oz of coolant standing in my J-pipe right below the throttle body. I drained every single drop, cleaned it, shop vac'd it, ran engine cleaner through it (twice) and got all the residual coolant out. Now, it runs like a dream. My point is, if you have a stock S55, KEEP YOUR EYE ON THAT STUPID INTERCOOLER RESERVOIR!! If it gets low, top it off and see how long it takes to drain. If it drains DO NOT HESITATE to buy a brand new metal one!! Those stock intercoolers are GARBAGE! They will destroy your motor!

I guess its a stupid question but how does it compare to the N54? The N55 was an attempt to improve on the N54 and the S55 fixed all those issues? Im reading that the N54 can take 1,000 hp but the S55 tops out at 750Hp?

7.3 gas next

N55 is cast they not touching the n54 internals

Valve Gasket leaking.

The crank hub is for sure a problem with power I build bmws for a living. You know what they say FAAFO

Completely wrong it’s not pre 2016 models it’s all S55 models I know of three post 2018 models that have spun crank hubs, it’s not blown out of proportion quite a lot of units that are running increased power have spun and as that’s most S55 units now then the amount will only increase. I’m speaking from real world experience of this engine over thousands of miles running stock power, stage1,2 and now stage 3 plus at 700bhp with Meth and running 4.9-5.1 second 100-200 times. Intakes do nothing for the S55 in fact most reduce power, even at stage3 stock air boxes with K&N or MMR filters are best.

For the price difference n54 ftw

Every year of the S55 has the crankhub issue

They went from V8 to twin turbo 6 so you don't get 8mpg on the f8x platform lol

Crankhub issues are a problem with any vehicle equipped with a s55 Not sure where you got this information where it only affects certain years . I’ve personally have done many Crankhub jobs . It’s not blown out of proportion. It’s a legit problem

All this awesomeness just to sound like shit with any exhaust lol! Thats easily fixed though with a big single.

turbos weigh 70lbs? really dude lol

Music too loud and annoying bro

Toyota had nothing to do with developing this motor. The are using the motor in the Supra
