- This was always a question I had, and I know many other have had. And there always seemed to be no clear answer aside from randoms on Bimmerpost mindlessly yelling that N55's suck. So I took it to myself to compile all the reading and forum digging that I could and come up with an answer. Hope you guys enjoyed and found this video informative!

Just as an FYI, the point of this video was NOT to bag on the N55. As an owner of an N55 BMW and someone who greatly prefers it over the N54, I made this video to explain some of the hardware limitations that users encounter frequently which hinder power gains. Turbo & fueling being the two biggest factors from everything I have read, thankfully there are solutions to both of those :)
One was allot worse than the other as soon as it hit 2-3 grand and you let go of the pedal it sounded like two metal spoons being clacked together Sounded just like the vids on RUclips titled spun rod bearing Ive been hearing more lately specially on 2011’s getting up to around 120-150k
As another N55 owner, its only reliable once you blow/crack every intake/boost pipe and replace them with aluminum
Bro it’s a bmw neither is gonna be reliable
Why even compare! You dont like the n55 dont freakinbuy it!
@@cloutlxrdgaming44 uou don’t know much about the n55 lol
As an N55 owner, I prefer the reliability over the power gains of an n54. I’m really not drag racing every commute so anything between 400-450 is just good enough for the car.
rod bahmanyari same here, that was my reasoning too
Except its not reliable lmfao. Bare issues on mine
Ollie Clark I’ve been having mine for about 4 years and zero problems 😏
x2 i had an n54 335i and EVERYTHING broke on it. N55 2014+ version is vastly improved. metal water pump. no fuel pump recall on mine. m235i now.. and power.. lol im at 380 fbo mhd s1 great daily driver
Rei N55 is super reliable and if you get a EWG version it is essentially a matured product hence the new generation of B engines. This means this product is at the pinnacle of its development and now bmw is working on a different foundation. Moving forward, if you notice on select cars bmw utilizes 2 water pumps, this solves the WP issue, and you see fairly any rod issues. I can’t even find more than 1 mention of blown rods in my car and it was due to owner issues. The n55 is a great engjne
Here you go.
N54 has forged crank and rods w/ cast iron pistons
N55 has cast crank, rod, and pistons.
Only the x4 m40i and m2 n55's have forged everything, and larger factory turbo. They even share the same forged rods as the s55.
Both engines are open deck.
All variants of n54 and n55 can make the same hp/tq unopened with bolt ons.
N55 cast internals have been proven to hold up to the same power numbers as the n54.
Both stock rods fail at 700tq, including s55.
The punchines/"more power" feel of the n54 comes from the true twins, simply because they move more air.
You will not get into big power numbers with twins, you have to do a single conversion.
N54's also sound more crappy not only because of the twin turbo setup, but because of the true dual exhaust.
You can clean up the sound by opting for a single pipe setup with or w/o resonators like the a80 supras. You can get an even better sound after pairing it with a single turbo.
N55 has the single already but a true dual exhaust. Go single and you'll hear an even cleaner/more aggressive "2j" sound.
In order to gain big power from either of these engines you have to close the deck and rebuild it with thicker forged pistons/rods/arp ardware. This is the same formula with open deck honda engines.
The only closed deck inline 6 blocks are the s55 and b58. B58 is the strongest stock block because the cyl walls are coated similar to the GTR VR38. 1000hp n54/55 blocks have to be converted.
The only differences in limitations between the two is R&D. Since the n54 has been on the market for longer, there are more complete kits and aftermarket support for them. DocRace, RK, and Motive are arguably the leaders in the development of parts and tuning. DocRace has a top mount n55 kit available, Turner Motorsport has a better looking engine cover (because the oem n55's one are ugly, all that's left for the cool looking factor is a front face intake manifold. DocRace will probably be the first to make that too. Once the n55 equipped BMW's drop lower in price and R&D reaches the same time as n54, you're going to see the community shift.
Fantastic information and insight brother. Thank you for sharing this seriously valuable info to all of us! Such great stuff! I should also add the N55 in the M235i got the forged crank and rods as well.
the m235i 2014+ n55 has forged crank btw
tbh im getting a used m240i soon and the b58 engine is even better.. then ill be doin a 600hp+ setup
@@seansurfn2 nice man! should be a sweet build
Sheesh bro read this whole thing, gotta say this makes me feel much better about the 2012 335i I’m getting. I’m saving this comment by the way. So informative. Predicate chu my guy 👌🏾
i still prefer n55 it sound better and i don’t need a 1000 whp to be happy
very true man, i agree haha
You clearly never drove one then 😂
Anthony Castillo i did but man the n55’s sound is the best
Anthony Castillo I have... he’s still right, you don’t need even close to half of that to have fun.
Nick, what exhaust are you running?
My buddies with N54s are always broken down. They've driven my 2014 F30 N55, stage 2 Bootmod3, are blown away by how fast it is. I'm in Medical sales and drive it all over Arizona, have around 50k miles on it with all my mods/tune. Never had a single problem with it, just your basic maintenance.
exactly man! i have almost the exact same mods except i also run E30 and im at 56k miles with zero issues
Do u live in phoenix
You still have the car? How's reliability ?
I want to see the different variants.
ill make a video on this topic
Only thing forged in N54 was the crankshaft.
Failed to note the N54 has piezoelectric injectors vs. the solenoid injectors in the N55. Many improvements in big end bearings, windage control, cooling pump regulation and oil separation on the N55.
Note to poster: Under hood air is hotter and less dense than ambient air. Thus power isreduced by the DME.
@@machtschnell7452 great points that i didnt know about. i read that the N54 had forged rods as well, this isn't true?
Crankshaft in f30 n55 is the same in the s55 f8x
Sick video dude. Extremely informational. More videos on N55 plz
Good info we need to investigate the n55 more for it's capabilities over the n54 seems easier to tune with MHD and for the basic builder that's all we need
I prefer the sound of the n55 over the n54 and b58. The Power with MHD Stage 2+ is enough and daily usable
Agreed man! Summed it up well
Do the variant video. I'm very interested to hear about the M2 noncompetition model.
Please make a video about the different n55 variants I didn’t know that was a thinf
N55 engine is super solid, I have a 15’ 335 performance edition stage 2 and let me tell you, this thing fly’s . I keep up with stock m3 /m4 & c63s...
Yea man, N55's are sweet! Love mine especially on E85
Me too I love my N55 2015 M 335i and it's fast. I don't know what this guy in the video is talking about. His set up is probably with cheap mods that isn't producing quality high power IJS. I"ve seen videos where they got the N55 up to 800 to 1000hp
No you are not keeping up with c63s with an n55 hahhahaa
I raced a pure turbo stage 2 full e85 M235XI and beat It in my M4 with Basic CS tune.
@@eninety yea with just a "stage 2" flash there's no way lol
It is EASIER and Cheaper to make power on an N54, but it is ludicrous to think you can't make high power on an N55 which is an all improved version of the N54, that gave birth to the S55 on the M3/M4... I had both and can tell you the N55's torque is unmatched by the N54 in stock form or even when you tune both with MHD and stock turbos. The N55 is a better engine period, just like the B58 is better than the N55..
yea id agree with you totally! i made this video to try and ease people's criticisms of the N55 engine haha
Leave the drugs please.
Is the B58 proving to be as reliable? I did a huge amount of research before zeroing in on a '14 with an N55. Now eyeing the current M240i.
Stock for stock i obliterated my buddies n54 from a dig. He has a e92 n54 2008 while i have a E92 n55 2012
@InGrindWeCrust2010 i might be a little late, but yes, the b58 is very reliable. probably the most reliable engine bmw has ever built
I own a 13' pre-July (if you know you know) F30 335i Sedan and my car was in the middle of the development stage. It's PWG. They switched to EWG in July. The wastegate difference alone will allow EWGs to be able to take 20-40 more hp more than a PWG car would. They also had the DME locked until May (dont' quote me on this) of 2013. HUGE differences that people don't realize until they start modding their cars.
I had a 2009 335 Tune and FBO and now 2013 335, tune and full fatback exhaust. From my experience, the n54 is a powerful and fun engine, gaining so much power from simple bolt ons. However, I did have many issue including high pressure fuel pump going bad, and turbo issue. I traded it for the 2013 before hitting 100k. The n55 is a lot smoother, but not as fast as the n54 with similar tunes. No issues so far and I am hitting 75k. I can see that car going more than 100k without problems. N54 is best but be prepared for unreliability and headaches
I'm running a custom map on my 435i with upgraded FMIC and DP and managed to get around 490hp and 780nm with stock turbo and HP-LPFP. Really happy with the result and no problems with the engine even with now 180k km on it. A really great engine if you maintain it right.
could you please share information about your custome tune?
@@Brad0st sure it has an MHD tune in combination with xHP Flashtool. Then I hit up wedgeperformenceracing and they made a cutome map via runs in 3rd and 4th gear while logging. They tweaked the map a couple times and I had finally those results. It was tuned to the max, more boost would result in a Railpressure drop, so thats the first thing which was limiting the power to under 500 hp. Also had a custome made exhaust system with only a resonator, decat downpipe, upgraded TMAP sensor form the N20, fully upgraded intake/chagrgepipe, upgraded BDV and upgraded FMIC. Probably forgot some things. But yea could keep up with a Stage 2+ 440i and destroyed M4s.
@@tyrox1667 can you do a build list for us pls 490hp outta a n55 ?
I got my M-packaged 08' 135i right when they came out, and sold it for my 15' M235i. Both first and only owner of the cars. Pretty much fell on the floor laughing when you mentioned the N54's advanced fuel system/pumps. BMW owned up to its issue, and slapped 120k mile warranty on N54's fuel pumps, so I respect them for that. Nevertheless, I was at about my 6th fuel pump by the time I got the M235i. Such a headache.
yea total headache for sure haha, it's interesting though since the N54 HPFP seems to be stronger out the box although not as reliable
SIX? GEEZ lmao.
That was across the board the minis had the same issues.
I guess you never bought good fuelpump insted of original?
Yes, please make a video about n55 variants. Many of these variants are almost different engines
Where to find tuning parts for this engine
Hey bro I’m looking at a 2007 335i coupe that’s a manual and has 118k on it. The price is $6500 obo... what would you say? Buy it or keep looking? Thanks
Is there a difference in turbo lag between them?
How much is the most I can get out of my f30 n55 and that the engine is safe?
So is there a difference between the n55 e90 variant then the f30’s as I’m stage 2 fbo in my 2011 bmw 335i and it seems to be that the stock f30’s can still keep up how come that is can anyone explain?
i’ve heard of some guys trying to retrofit the S55’s dual HPFP setup but i think it’s pretty costly
ive heard that as well! but very little info surrounding that topic and how easily it can be achieved
So what about the 2011+ E82 135 N55’s?
306hp slow? The heck
The point of twin scroll is for faster spool up of the turbo.
yes, very good point
That was the point of the N54s small twin turbos as well, but the cost to outfit the engine with twin turbos is more money than a single twin scroll turbo setup. Only reason they did it was to save money
@@pgr0104 yep, id argue that the twin scroll does that job better as it can spool very quickly.
Earlier version of N55 came with same continental style HPFP as N54 HPFP... how do I know, I got one.
lol
Have you raced Gios current car/setup yet with your current car settup? I think it would be a good race.
i havent with E85. I raced him a while back with his E60 FBO N54 when I was on pump gas and i kept up somewhat, but i havent gone against his newest 335i
love going back and watching these videos, such good knowledge to refresh on every so often
really appreciate the support bro, means a lot :)
What remapping software/hardware did you use for the N55?
Full Bolt ons and I flashed the car with Bootmod3 from Pro Tuning Freaks
Did you get an engine code from the burger intake? Suggestions?
I'd like to know different changes they made for the N55 compared to other N55 as you were saying at the beginning of the vid
Long Vo i just made a video on this, check it out on my channel!
Variants please! I have a 2011 n55 and I'm curious.
I made a variants video! it's the one i posted right after this one
Spool performance has a HPFP in beta rn my buddy has it wasn’t as pricey as xdi I think
so freaking awesome! cant wait to hear more about their product and results!
Ya only $900
N55 sounds amazing though.
i wonder if my 2015 335i msport ewg has a forged crank?
I believe it's cast
What you’re saying about the twin scroll is kinda off, a twin scroll is actually better than a twin because how it works is it dynamically adjusts at different RPM’s one gate is larger than the other so you get appropriate boost throughout the rpms.
So if u have FBO done will the horsepower increase be the same in both engines or will the n55 make less power ?
N55 with fmic and stage 2 mhd tune can produce up to 370 HP. That's what I'm looking to do with my 335i hopefully by winter
very solid power levels!
I have the N55 I did the intake and charge pipe with mhd stage 1. I recently bought my intercooler and catless downpipe. I'm going to install them at the same time with mhd stage 2+ so I'm not buying 2 tunes. What kinda power do you guys think I'll make from that?
I have a bit of confusion here. Don’t s54 owners go single turbo for big power? The shop in Nashville 2 years ago specialized in that. Isn’t it the same reason people ditch the twin RB for a big single RB?
Yo can you make a vid on the s55 crank hub problem?
yes! thats actually coming very soon!
I had a 14' N55 in a 335i - had the dealer install the Dinan stage 2 tune. Within 1000 miles it was in the dealer countless times with issues. Went into limp mode x times, blew the intake pipe twice. Needles to say I traded the car soon after was just a headache.
wow, i'm surprised to hear that. My 2015 M235i has been tuned with E85 and is at 56k miles not a single issue
As someone who came from buying 1000$ shitboxes like old civics and fords with 0-60 in yes seconds, i was absolutely perplexed when i got to do a test drive on an f30 335i xdrive... its a whole other world going from sub 100hp cars to something with 300hp... i couldn't fathom what i had experienced and immediatly bought the car.. it didnt take long before i started to venture into mods. i'm not a mechanic by any means, but working on my own cars and doing maintenance is something i've always done since i ever had my first car. i never had this joy of buying parts online before, and installing them myself.. that's when i found out about flash tuning and again, changed what i really thought cars where capable of.. after installing a blow off, intake, intercooler, charge pipes, and fuel components, i went straight for a downpipe and got a mhd stage 2+.. i'm certain the car feels like it has around 450whp and i feel like i can gap any car or supercar (just that greatness feeling lmao) and honestly i absolutely love the damn thing.. its sharp, fast and nimble.. more than what i need, more than whats needed to even drive on the streets... its something i take pride in, coming from shitboxes to something i built by my own hands and makes me feel tremendously happy.. no joke, building this car in months it took, eased off on my depression, and driving it like a hoon is it's own experience to cure it.. we dont need 1000hp big turbo cars like everyone on youtube or social media is doing.. just find a good platform, mod it and tune it to your taste.. drive like you stole it (responsibly) and have fun, with the 300 or 400hp that the car has.. it's way more than enough. cheers
awesome video!! thanks!!!
thanks for watching!
Please make a video on the different variants of the n55 engine
i did! I uploaded the video yesterday
Yeah I'm pretty close to the limit with my stage 2+ 400awhp n55 but you really don't need more power for a daily, since upgrading from stage 1 I rarely go WOT from a stop anymore cuz it gets up to 60 pretty quick at 3.7 sec and I still get to make my friend jelly that his brand new m340i won't beat my little F32 lol
-Edit: I'm pretty much at the limit without doing major drivetrain upgrades, F Chassis AWD can't handle that much HP stock
Yeah I have a 335xi as well. The 8hp50(mines a '15) handles power just fine,,especially if you reflash(same with earlier 8hp45) BUT the dang 180mm diffs that are welded and open really limit power handling. It is possible to have lsd's installed but stupid expensive. If I ever get to install an 8hp70 then I'll look into seeing if I cam sntall the 210 diffs front and rear with a bolt-on ring gear(to send in and install an lsd on the stock diff it's around $2400ish per)
I love the N55, it's full of torque and sounds amazing, I just gotta drive a B58 car to decide between a 435i or 440i 🤔
N55's are badass, but man the B58 is on another level! You gotta drive one!
Tim C B58 is chaos. Shit bangs!
Tim C Get a 440i. Very cable motor stockwise
I have a 140i stage 2 running 452bhp. Monster!
Bro 440i eyes close .b58 it is way faster than a n55 b58 its an upgraded version of N55
in my situation does the bmw 2013 528i have a n55 or n54? what years are mainly n55
That has neither. A 2013 528i would be equipped with the N20 Turbo 4 Cyl engine I believe
@@SimplyCarThings that is correct. The same engine as the 228, 328 and 428
Only problem I’ve had with my 2016 f22 is offer putting the JB4 tube on it is that it eats through charge pipe I’m in my 3rd in less than a year (it was fine stock) and I’m hoping to get an aluminum one instead.
with all due respect that was a very foolish decision to tune before upgrading ur chargepipe, chargepipe is the first thing you need to do before anything else with these n55s, i gotta ‘16 m235i myself and did the cp and FMIC not long after preventative purposes
Does the N55 in the M2 have the same crank hub problem? I am thinking of buying one for track days and perhaps doing a few bolt on's, nothing crazy maybe 400+
I think it was the first time ever i actually smashed the like button and subscribed lol
haha, appreciate the support man!
It's full bot on, what exactly is FBO on this car?
intercooler, charge pipes, intake, downpipe, maybe exhaust....
You mentioned only the EWG N55’s vs N54’s but forgot about PWG N55’s like in a late model e82 135i or e90 335i when talking about fueling. The short on our systems is the LPFP, which is already a stronger system than the EWG cars. Just like the N54, the PWG N55 HPFP is the stronger of the two N55’s, and most of the time is good for E60 blends without port injection. Plus a bonus is that it’s way cheaper to upgrade a LPFP than a HPFP! (Unless you factor in having to replace it around 120k if you’re outside of their class action lawsuit timeline for the HPFP)😉
@Simply Car Things feel free to share those information!
idk but I’m getting an n55 with this 335i and I’m only looking to make 400whp as a daily tbh
Just incase anyone visits this. N54 never came with forged internals, maybe crank... but the rods and pistons was debunked on bimmer post.
From what I'm understanding, it's literally the twin turbos
With the mods applied to this n55 what’s the top speed?
im not too sure but id guess around 170ish mph!
Simply Car Things I removed my limiter on my 2011 335i MSport PPK, and 160 on a runway was not even an effort.. Didn't go full top speed as it was a small private airport in Nevada, so I can see 175 or a bit more

thats something others have been saying! please keep us updated with how that goes
Is the swap difficult? I have a 2017
@@usernamealreadytaken770 It's not too bad, the actual pump is awkward to get to, and all you have to do is cut the flange on the new pump. The HDP5 evo pump is easier to fit than the HDP6, due to the angle of the connector of the 6, you have to dremel a small bit of plastic from the inlet manifold. You're not from Louth are you mate btw?
gynads No, America.
How is it going ?
A twin scroll miminc a sequential twin turbo. I belive n54 are parallel turbo setup. So not exactly the same feeling. N55 would be way more linear for the same total output. Thus faster.
thank you for the clarification!

N54 forged rods and crank, N55 doesnt. and I do believe the the N54 block pistons sleeves are stronger as well
not entirely true. Certain vairants of N55 such as in the M235i & M2 got forged crank and rods as well. The N55 in the M2 also has the valvetronic, bearings, and pistons from the S55 as well.

Alpina still makes their B3/B4 by taking N55 and putting Mitsubishi turbos from N54 (+ forged crankshaft, larger intercooler, NGK spark plugs, aplina ECU and TCU flash). So current Alpina B3/B4 is basically a N55 + N54 turbos, it makes 440hp and it's a stock car with all warranties
very interesting! i had no idea they did that!
Simply Car Things they have this info on their web site. Don't remember if they clearly say ”N54 turbos”, but you can definitely recognize it from the picture of on their website
How do you afford this
i work a job, and live at home
e92 335i n55 is the perfect balance. you get the reliability and power without the newer n55 limitations
Idk what limitations you’re referring to regarding the later n55 iterations. They’ve became more robust and tuner friendly. For starters adding an ewg as opposed too pneumatic. Also forged crank and rods as opposed too cast.
Stock Turbo (EWG) N55's are running mid 11's. 99% of custom single turbo N54 cars are 11 second cars so how much more hp an N54 can make doesn't mean shit really. After 13 years there are still only a handful of N54's running 9's and barely. And there are not many 10 second N54's either when you consider how many were built.
totally agree man, I think with N54's a lot of the bragging has become simply a numbers game which is somewhat meaningless in my opinion
E series PWG n55s can hold more E85 (E50) than EWG (E30) cars stock.
ive heard that as well, do you know why that is?
Simply Car Things I would like to know as well since I have a e92 n55 335i
@@MRBD18140 If you car is built before 3/12 it can run up to e50 with stock hpfp. Its because those models share the same HPFP as the n54 did.
Upgraded LPFP is still recommended
Want to see the differences
N55 does sound good though.
E82 and E9X debuted in europe in 2004 and the N54 debuted in 2006! thats why the pre lci cars in 2007 have a different chime because thats the chime from 04-07!

You can literally can upgrade an N55 to a closed deck.
Everyone just loves to say the b58 is better and the best bmw ever made
You must not heard of "@1StockF30" on Instagram Aka the N55 King....
the point of this video wasnt to bag on the N55. As an owner of an N55 BMW and someone who greatly prefers it over the N54, the point of this video was to explain some of the hardware limitations that users encounter frequently. Turbo & fueling being the two biggest factors from everything I have read. And yes i have heard of 1StockF30, his car is badass.
I think BMW figured out that you can get a N54 335i, put some money and take over some E9X M3s. So they built their N55 so you can’t take over their F8X M3/M4.
Now, explain N55 differences between E and F chassis. Even their down pipes are different!!
This kind of makes sense.
However, in the used market I don’t really see the advantage of buying an N54, I only see disadvantages.
The N54 has so many problems that it isn’t worth it to buy one used, even if your shooting for 500+ HP.
It’s very likely you’ll need to upgrade the N54 turbos, along with various other issues. The cost you’ll spend fixing it will exceed the cost to simply upgrade the N55 turbo & fuel system, and you’ll have a more reliable, newer car.
@@ChristopherGuilday When you think about back then, ten years ago, it makes perfect sense. Right now you get a tunable B58, makes more power than the N54 and way more reliable.
EWG can handle 650 on stock block, Wheel power. same as the B58
No it can’t it’s not forged
@@KevinTorres-xc2sv Lolwtf, B58's are cast, and they can do 750 on stock block, what are you smoking ?
@@G42Shady I was talking about the n55 dumbass lol
@@KevinTorres-xc2sv Both N55 and B58M0 are cast lol, what are you on about ?
only the B58s in the supra are forged rods & crank
N55 with the ZF 8 speed. That ZF transmission is incredibly quick. Even stock. Throw an XHP flash tune on it and that car will be/feel like a little rocket. My wife owns a m235 and it’s the most funnest car to drive, she won’t let me tune it but for some reason I enjoy driving it A LOT more than my full bolt E90 335i making 450WHp.
Sometimes I feel that it’s just as quick. Wish she’d let me full bolt on it I could only imagine how fun yours is bro
I’m in the process of buying a 135i N55 having come from a Chevy Cruze with a blown head gasket and I’m sure the N55 will blow my mind. the exhausting pursuit of the “best version” of a bargain sports car feels pointless. The N55 may not be as “tunable” as some other model, but it does have that fancy screen and swanky rotary dial at a price that I can afford. That alone is worth way more to me than the ability to get more power out of expensive bolt on parts that I would never use to begin with because it would void my warranty anyway.
The n55 is a highly tuner friendly engine, especially the n55b30O0(m235i) and the n55b30T0(m2) due to their forged pistons, crankshaft, and additional oil cooling. Upgrade the charge pipe and you’re good to 400whp, upgrade the intercooler and you’re good to about 450whp before you start getting fuel cutting issues.
N54 vs N55 blown WAY out of proportion. So N54 makes a little more power on stock turbo. Ok. N55 maxed out stock turbo still fast af compared to other cars. Then, just turbo upgrade the N55 if you want ultimate power. 🤷🏼♂️
Meanwhile N52/N53 sitting beside the pond waiting for fish to come..
lmaoo!
Big misconception.. all n55s have forged connecting rods. many forms have confirmed that. Its the earlier models that have cast cranks. The wear point on earlier n55s is not the rods but the cranks. When we see failure its cranks splitting, not bent or snapped rods.
interesting, i did know about the forged rods. I actually broke a lot of that down in my N55 variants video
This is no longer true we broke 1000 hp boys
The reliability and sound of the n55 far outweighs the HP difference. Most people don't mod and try to squeeze out every ounce of hp from the turbos when they buy car anyway.
Been seeing a lot of n55 guys have rod bearing issues lately
That’s caused by OFHG not done properly, N55 engines are known to go over 200k miles, some have gone almost 300k, original turbo.
I’ve been looking for a 2011 for a few weeks now and out of the 6 or 7 I’ve checked out 2 had rod knock I’ve been seeing it more and more
thevernonposse you sure it wasn’t vanos, n55 may have rod issues if people don’t follow oil priming procedure when changing oil filter housing gasket. Also long oil intervals doesn’t help.
I’m hitting near 500whp on my f21 m135i n55 and I can have it more up than this. They do over 650whp on these engines without internals. All the n54 55 b58 all need big changes to make great power, a turbo upgrade and hpfp the right fuel and bingo they all do it. They get to certain point and all will break and need internals for big big power
im not willing to change my fuel. E85 isnt easy to find.
N55 is reliable but why go N55 when the new B58 makes more power and also seems to be reliable? Edit: Also yes please do a video on all the N55 variants!!
good point! I think it mainly comes down to price at the moment. Many N55 powered cars have seen significant price reductions in the secondhand market.
@@SimplyCarThings some of the older cars have gone up in value, i got a 2016 m135i for £15k, can sell my spec a year on for nearly £2k more than i bought it for
the N55 on the M2 is more of a mix between the normal N55 and a S55
That’s false. BMW switched to a detuned S55 on the m2 competition model. The N55 one isn’t even in production nor did it last long
@@guidoluzzi66 were not talking about the M2 competition here
