In 2006 when BMW dropped the N54 it was their first mass produced turbocharged engine. Previously BMW had produced a turbocharged engines in the past such as the M102 and M106, but those engines were limited production and never had successors. BMW had a long history of producing excellent naturally aspirated engines, so the N54 was a huge change for BMW.
Not too long after the N54 was released in 2006, BMW began implementing the N55 in 2010 in the 5-Series Gran Turismo. Compared the N54, the N55 had a significant amount of changes that were desgined to make it more reliable, because the N54 did have a substantial amount of problems. While the N54 was BMW's first mass produced turbocharged engine, the N55 was their first engine to use a twin-scroll turbocharger.

I'm not a big gearhead but I have this engine inside a BMW X1 2013 it's incredible, I love it more than enough power for me this thing can go 130 mph all day on a highway it's smooth clean not too loud, daily driver so good!!!! Thank you for sharing this video it's good info
I’ve got an N55 M135i my first BMW coming from a VR6 Golf. It’s always crazy to me how this thing looks so understated but is a very quick car even in stock form.
ty for the vid, i got a 2014 i435 and ive been struggling to find information about to motor. Or even what motor came in my car........... but this was highly informative and ty. keep up the good work u got my subscription.
N55 also sounds better than n54
Because you get all six exhaust pulses through one turbo.
Don't make it better.
I pull +600hp in my N54 and it's not loud at all. That's the best part of it all. I pull up to a 5.slow or a 392 with all there cutoff mufflers and I just walk them every time.
Sleeper is the way 🤫
@@mattX5 No your incorrect!
Fact!
@@mattX5 Whatever you think 👌
You obviously not into that platform.

@@mattX5 bruh he literally owns the car
how are you supposed to prove him wrong
Thanks for this 🙏
Dude thank you for this video. nevertheless where can i find those bolts(8.8 Ff) that hold the vanos solenoid (10-12)? please and thank you..
Thank you very much super helpful information, I'm picking up an X1 with this engine and will leave it stock have no interest in tuning it I just want reliability out of it, I was worried about the timing chain issue i'v hear on the n-20s 2.0 engines but you mentioned none of that thank you again
Thanks for the video. I learned some things!
Thanks for watching!
Got a lot of love for the N55. IMHO it's smoother and sounds better than the B58. Definitely is a lot more smooth and easier to drive on the limit paired with the zf8 compared to the S55 and DCT.
great video!
Huh, didn’t mention anything about the M2’s N55 variant? That is a big bummer I got really excited for this video. Not only is it the most revised version of the N55, but they also insert many of the forged internals from the S55. Not to mention the lightened flywheel and extra oil circulation systems they added. It really is the last hurrah of the N55 and it sounds amazing to boot!
Yeahh, I was actually waiting for this to be mentioned as well 😅
...and then you have the M135i/M235i version in between with some of the M2 goodies.
+1, unlike n54, n55 is not one single engine, it’s a group of engines. While these are mostly identical, some variants can have different specs for internals and different power potential
@@kringlefanten info on it is kinda spotty but afaik it has the forged crank and rods but cast pistons
N55 in the M235i (N55B30O0) has a forged crank vs cast and the (N55B30T0) in the M2 has upgraded internals and a semi-closed deck design. There are people pushing 600+ WHP on stock bottom ends on these.
Correct, but no N55 is semi closed all open deck
Have a 2016 M235i with auto tranny that I bought new. Don't track it but do some street racing from time to time. Been sending the oil out to Blackstone Labs for analysis with every oil change. Last analysis (53,000 miles) showed a bump the iron content. Blackstone says it's still within limits, but I don't like it and obviously that has to be coming from internal parts. Average for iron in the oil should be 24 ppm (parts per million), lab reports 34ppm. Any reports of the N55B30 engine eating itself? All the other metals are at or below the universal average level.
Current stock engine n55 record is 760whp...pretty awesome!
@@sunny71169 Any news a year later?
@@markburkey6371 The oil analysis with the next oil change -(10/7/21- 64,225 miles), iron was down to 27 ppm with the average for that engine reported by Blackstone to be 25 ppm. Blackstone's report stated "Your BMW is bringing home another stellar report. Aluminum and iron went down after a longer run, [aluminum went from 8 ppm to 6 ppm average is 9 ppm]and that's a very welcome result. Iron tends to fluctuate a bit between samples, but there are probably operational reasons for that. Your N55 still produces a lot less iron on a per-mile basis than most we test. The universal averages show this level of iron is normal for most other N55s after only ~5,800
miles. Nice trends for a nice engine."
I have had NO maintenance issues with any part of the car since its purchase. Total brake job at 49,999 miles-(pads, rotors, hardware, etc) under warranty. Cost to me was $0. I do the factory (NOT DEALER) recommended maintenance as per the manual, either myself or let BMW do it depending on the operation.
What internals can I retrofit into the n55 internal motor? And where is the best place to get n56 turbo parts.
I have an 2016 built N55 inside an X5 xDrive35i that's been tuned to the M Performance power kit. Apparently late production N55 share the rod bearings from the S55.
I own m235i and it is a beautiful sound engine…Great car🏎
u have the msport exhaust? mine doesn't sound that beautiful lol
@@bella_testastretta engine sound…But i put wagner downpipe
@@madmaxx8800 Nice. I don't think the engine sound is that good either. But if you come from a 4 banger then I understand lol
bro just get a muffler delete and or catless down pipe itll be perfectly loud, im stage 1 just muffler delete and its super loud and 380 hp
very informational
There are at least three versions of the N55. The "base" which is used in most regular BMWs, the M135i/M235i which has forged internals except pistons, and the M2 spec N55 which is even stronger. Also, the early models until the middle of 2013 had the pneumatic wastegate and will have a lower tuning potential.
I’m
Sure it’s only the m2 or 1m .
The m135 and m235 only have a forged crank .
@@JusZard the 1m is an n54, also all n54 and n55 have forged rods and hypereutectic pistons.
not forged mate
Good video
Thanx 👊
Thank you bro
What about BMW Z4 2012 v6 turbocharger any common problems?
Did you just say v6?
Actually the late 2014 N55s came with forged crank and rods, just the fuel system in the N54 gives it that advantage of them
I have a 2015 335i with the N55, I thought the forged bits were only on M cars?
@@a9653192 depends if your car has the N55B30 series engine, this version does not have all the forged bits of the N55B30O0 (M235/M135i engine code).
Shival Ramkelawan yeah no I don’t have the forged bits. I have that N55B30M0
late 2014 435i’s too?
@@a9653192 All N55s have forged rods. Higher performance variants have forged cranks. M2 variant has forged pistons, upgraded bearing shells, upgraded oil pump, lots of other minor modifications.
Their weak spot is this valvetronic motor, which is made from plastic (Lol at BMW for this decision). The eccentric, intake and exhaust camshafts often have issues as well. This is weak engine. Had to open it and replace the valvetronic motor and the eccentric camshaft. Now I have to replace the intake camshaft as well - it's scored. This is weak for an engine for me especially that I still haven't replaced the brake pads (at 110k km's) but had to replace the valvetronic already...
2015 m235i @ 80k miles. She's been good to me.
Im at 52k with mine, any issues for you? Im doing 5k oil changes and spark plugs soon
I always thought, until today, that the N55 was the one with forged internals. Can you swap N54 internals to the N55s??
They make rods and pistons for the n55
All n55's and n54's have forged rods and hypereutectic pistons. But only some of the n55's have forged cranks. The lesser cast crank hasn't been known to be a failure point anyways though.
To my understanding n55s have forged crank and rods as well.
only on the m235i/ m2 i believe
@@iamtygar only the M2 does.
Nope n55b30o0 in thd m235i has forged rods allso wedge tuning makes m 680whp on a stock n55b30o0 engine in there car
@@erikmoralesrenteria2464 theres no difference between bottom ends in n55 variants
@@evanwalsh8808 Incorrect. The O0 variant has a forged crank and rods. The T0 in the M2 adds the pistons and oiling system from the S55 as well as cast iron sleeves for the bores.
great shirt, great album
Welcome to Forever is still my favorite album/mixtape but The Incredible True Story is a close second.
@@Dustrunnersauto :)
Not sure about n55 only making 500s dude just posted n55 f10 with 700. I got quoted 580 with stock turbo and stage 3 fuel pumps with my bolt ons from someone with same car and parts!!
You should do one on the vr30ddtt vs vr38dett
F20 N55 and up have forged crank and rods i believe.
Just crank
u told a lot of stuff here thats not true. First of all, stock turbo is capable of making 450hp with all bolt on stuff (cooler, piping, etc etc). Internals can handle 600hp in daily use. Ofcourse everything will break someday, but you got the point. Been there done that.
Yeah, maybe 400hp w meth/ e85 and fbo.
Got 125i with N20 and looking at m135i upgrade with N55. Lot of upgrades (brakes, engine are the main ones) but the possibility of some of the issues scare me a bit tbh
Just a proposal: Sell your 125i | Buy a solid 135i. Greetings from Munich :)
@@Vale-sk5jf lol... yeah, should totally do it :)
@@juraj_b did you?
just buy a m140i and you get the amazing b58
How do you solve the unreliable water pump
I have this engine in a hatchback. M135i
Who knows what exact transmission is in the 2016 F36 x drive (435xi) grand coupe ? Is it the first or second gen ZF 8 trans? Because I know instead on doing the LCi in 2016 they just went to the 440i in mid 2016 which was really stupid on their part, granted I just traded in my 2020 M5 comp for a brand new G82 M4 comp, I had the 07 e92 n54 with fbo and tune making great power but I use the 435 as my daily but I want a tasteful tune on this car I’m thinking JB4 I’ve already went with dinan and bootmod3 as we’ll as a jb4 G5 back in the day of my N54 ,and I cannot seem to find info on the GC I know it’s loaded 8 speed m sport package but not performance pack that’s the only option I left out . Literally costed me as much as a base M4, it’s like a mystery to everyone . Lol even wiki/forums/other F30+ guys dont seem to know. Thanks in advance !!!!
All of the variants of zf8 speeds will be fine with tuned n55s I would recommend tuning the transmission of course
Is it easy to put an N55 into a vintage car like a Triumph TR6 or TR4A without breaking the bank?
spot on intelligence thank you for that ! with that said i have a 2011 335xi sedan stage 2 single twin scroll turbo upgrade , ghassan remanufactured n55 engine , stage 2 dme flash, all new valve cover , valvetronics motor , dme , delphie coils , plugs 1 step cooler, new oem bmw 6 injectors , and after about 1500 miles driven now, I'm noticing a ticking noise almost like a baseball card in a bicycles spokes upon acceleration when car is in gear driving only ! when in park or neutral and revving car , no noise ! only when in drive under medium or higher acceleration around 1500-3500 rpms then goes away in higher rpm,s ,doesn't happen at all under normal acceleration ? no one can figure out this issue ! please help !
most likely wastegate rattle, pretty common on n55 and n54, could be a faulty turbo or just nothing to worry about depending on how bad it is
Why you'd leave out the Mercedes OM606 I don't know.
I currently drive a F30 N55 335i with 450whp & 500tq on E50 . Not bad , but also not enough .
what you got done? i’m tuning mine next week
So just upgrade the internals and boom a built n55 is born
Which model n55 does the 2011 335i have?
just answered your own question
@@charlestucker6365 na there’s different variants! Of each model for example n63 n63tu2
Had a rod knock in my n55 with regular maintainence. 10,000 later my car was back in business
Have u done the oil filter housing gasket replacement before it knocked? Do you own a e9x chassis? Mileage?
what bmw?
@@jasonminhas377 535 xdrive
You didn’t do anything to get it fixed?
@@Yeer718 what do you mean? A rod knock meaning the engine would have to be dismantled and rebuilt.
How is the reliability with a tune at +- 350whp for daily use ?
Awesome, no issues!!
same here no issues and i'm at 380whp on pump gas
No issues
Depends on whether its e series or f series. E series has n54 problems, f series n55 is pretty minimal on issues
Just an issue with my injectors , but i assume because I have the first year f series n55
HEY!? THANKS FOR A WHILE I THOUGHT I WAS THEE ONLY ONE TO EXPERIMENTALLY!! BE PUSHING [THIS GERMAN ENGINE] (N55) TO IT'S CUTTING EDGE!!! MUST SAY THO! BMW'S MAKES SOME VERY!! EXCITING ENGINES!!!

I got a 2011 E88 FBO was able to achieve a 475 torque but only 335 hp to the wheels. Stock turbo and stock high pressure fuel pump. With a costume tune by mhd and tuning dynamics and a xhp transmission flash on the DCT transmission. Those numbers where done with a 93 degree weather and 52% humidity. I forgot to mention that was done on pump 93 octane. Debating on upgrading the turbo because I want at lease 450 whp but idk how reliable that will be. I forgot to mention that I also got a remanufacture engine with forge crankshaft and kings bearings. Anyone here with a n55 with 450 or more whp? if yes what you got done to it?
I daily drive a n55 stock engine at 700whp
What are your mods?

N55 is cheaper to maintain and build so sad about to missing forged internals
Really
It’s definitely a better street car engine than the older Japanese sixes.
No direct injection I6 is a better street car engine than any 6 from the 90s. Especially not the sequential turbo Japanese engines lol.
i have the same logic shirt
N55
i thought the n55 was twin turbo
Record for N55 is 697 HP
There’s ways to get higher
Now here’s a update crank hub rods pistons and head studs with a turbo and port injection e85 makes 1100 hp your welcome boys
Crank hub issue.....
I expected a shitty long video but this one was pretty good.
I have 2015 435i xDrive gc (n55) with 70k on it. Engine seized, battery died and starter went all at the same time about a week ago. Connecting rods and bearings are done. Car has MHD stage 2+ with FBO. Never abused the car, always drove it and treated it very well. Shit luck!
That’s some bad luck! Hopefully my N55 doesn’t explode like that 😂
Just got mine back from BMW. New engine from Germany, Dealership found metal in oil filter during trip for drivetrain malfunction. Thank goodness for engine and drive train warranty. 49K on the motor. Initial issue was a wiring harness. That replaced and issue resolved.
I have the same exact car I was thinking about getting the same tune do you think the tune had anything to do with this engine crashing?
Nah the engine seized up and you killed the battery and burned the starter from all the attempts trying to start it. 🤣
My wife got a 2007 n52 and it not running to good. Been hearing alot of good things about n54 and n55 swap. Which is the better engine if it going to be for a toy. My daily is an f150 and my wife drives a Toyota Corolla. The BMW is strictly going to be for play and riding around town and showing off. It will be long term project.
Open to all suggestions just give your reasoning for what you would choose.
If you can find an M2 or M235i N55 - code is N55B30TO - that will be the one to have. Some internals from the S55, better oil circulation, and RK Tunes will get you to near on 700 wheel horsepower on stock block, while offering better reliability than the N54.

Are you talking a specific n55. I only ask cause I plan on turning it bottom up and putting all forged internals. That said everywhere I'm looking for reliable transportation go n55 for street and strip go n54.
I promise I'm not disputing what you say I'm just looking to get as much info as possible
N52 is one of the best running bmws ever! Not for power but for dailying
Not all N55 are created equal. For example, the M235 n55 is good for up to 700hp
Yeah because it has some forged internals . The N55 is great regardless if your going to put that much power down build your engine anyways .
@@JusZard just the crank
@@mustangman3769 and rods allso haha
These engines aren't even in the same ballpark as the 2JZ or RB26 and built a decade later.
The engines were created in different time periods and conditions, so off comparison. Besides the b58 has proven itself more than capable and just as good as the 2JZ so there’s that.
I’ll take the b58 over 2jz.. power just comes in way quicker
People crap on the N55 when it comes to the B58. B58 isn't better. N55 can produce the same big hp numbers reliably that the B58 can. People are always infatuated with the latest thing. Building my F30 335i for reliable high hp.
Not true cause when the n55 came out people still liked the n54 better

Am i the only one having problems with the oil pan leaking oil from the oil pan plug on the 2014 x5 n55 35i???😔 oil pan costs $1,000.00😩
That's from somebody over torquing the drain bolt I have a couple e90s like that. All you need to do is read tap the hole re threaded. And oil pan does not cost $1,000 it's very cheap and easy to do just time-consuming dropping all the suspension connections. People say about cover gasket is $1,000 job too but I just took off my valve cover in an hour and a half time and putting one on in 30 minutes and I've never done it before just goes to show that if you mess with suspension and bolts then you can mess with some motor components do your own work. But as for your oil pan issue you can go to any shop and they will re drill and tap that for probably seventy-five bucks but then you want to make sure you get all the metal shavings out by changing the oil and flushing oil through to push out shavings good luck
BMW 335I i bought the oil pan from bmw near me, and it did cost me Over $1000, i tried looking for cheaper one but had no luck, used cost $600 and brand new did come with a 2 year warranty, “2014 bmw x5 xdrive35i n55” and about the retapping for the plug, i am very Very concerned about the shaving of the reedrilling, last thing i dont want to do is buy a new engine that costs over $4grand and am not even done paying for the vehicle.😩😔but thanks, am reconsidering replacing it my self.🤷🏻♂️ its a $2400 charge just to get it replaced🙁
@@fivestarhemi2877 you shouldn't have bought that obviously, for a rack. As for the shavings that's why there is many tools that you can use they're are drills with vacuums on them you use oil to push more drilling out of the whole many different ways to do it they even make a cool set that makes it impossible for shavings to get in there and many ways to do it I've done it many times
