I Got Tired Of My E90 BMW. This is Why

- In this video I tell you what made driving my E90 a drag and what I'm doing to fix it. If you've been following my channel for a while you'll know that I manual swapped my E90 335i BMW with the N54 engine. If you've been following for even longer you'll know that I also converted my stock small case auto differential to a limited slip differential.
When I swapped to manual I did not replace the differential so in this video I am changing the diff out to a large pumpkin 3.08 and removing the 3.46 small auto diff.
The car was a little too high strung with the 3.46 final drive gear ratio and it made driving the car on a regular bases not enjoyable.
In this video I show you what is involved in replacing your differential.
I know you guys wanted E90 content, near the end of the video I discuss what the future plans are for this car on the channel.
If this is the first video you are catching of mine please consider subscribing. I upload regularly.
Thanks for watching :)

This video was right on time. Been debating on 3.46 vs 3.08 for the money. Almost pulled the trigger on the 3.46 last week. Glad I waited as I just upgraded my turbos instead. Forums did not help with this topic. As always you provided the feedback with actual experience. Thank you for your continued contribution to the bmw community.
Depending on your mods (what turbos etc) and power curve, shorter could be slower too. 3.08 definitely comfort on the road, lower cruise revs
Fwiw I'm going to be trying 3.85 out for size, may settle on 3.62 or even just sticking with 3.15 or swap depending on the track, but that's on a track car with no road manner requirement.
"To start with I'm gonna remove the exhaust" said no one from the northeast ever.
That's what we like to see. Good ol' E90 content
Being this proficient working off your back like this is a skill in its own right
Glad to see you putting n54 content back out there. Great information on the different diffs
Respect for working on your back.... I can't do that anymore... love your channel..!!
Agree!.. hope he gets a lift soon, perhaps even through a sponsorship!
100% dude needs a lift! I would lose interest in cars if I had to do that 🤪
He’s slacking I bought a 2 post lift used for 1k
@@the_first_resort940 yea, I got mine for about 1300 😂
@@BimmerHausPerformance it’s crazy some jobs alone the lift would pay for itself.
I'm still happy that you made the time to make these vids, thanks again!
one of the most enjoyable bmw youtuber to watch 👌🏾
Really amazing how clean the car is underneath.
No rust att all.
Cool video. I feel the same way with my 123d. It has a stock diff with very short ratios, 2,46 I think, but I bought it with a 330d diff with a big case and 3,08 ratios. So much smoother and at 200km/h(125mph) I only have 3100 rpm!
Thanks for all your hard work, as always killer content. You r the man,,
The best DIY BMW channel by far! Keep it up!
Although I have an M2, I'm learning a lot from your channel!
Yesss! N54 Content!!💪🏻🙌🏻🙏🏻 Can't wait for LSD conversion and omg single turbo conversion!?!?! Yess please!!!🙏🏻🙏🏻😁😁🙌🏻🙌🏻
*E9x content
Thanks for the ongoing e90 content. It’s simply a great car. Hence likely the reason you enjoy driving it while still owning a G80 big grill.
You’ve helped me maintain my 2011 335i XDrive, and I am also considering the manual swap. I’ve been told to use the N54 manual trans (stronger and cheaper) than the N55 counterpart. Any truth to that?
Great work like always!
Two thumbs up for the LSD. The stock open diff absolutely destroys the driving dynamics of the E90 335i. I 'upgraded' mine with a Wavetrac but was sadly disappointed. It felt like it was completely off, not doing anything, until a wheel started to slip, then it would (slowly) spring into action, but way too late to do any good. A waste of nearly five grand. I'm in an F80 now. It has it's problems for sure, but at least is has a proper LSD.
Thanks for the content and for the advice about diff gear ratio and your experience with it, its so nice to have a reference about it.. cant wait you to retrofit genuine lsd (wavetrac) hope so 😅, whatever you chose hope you explain why you chose and what are some options and benefits.. every bit of your knowledge that i can im using on my build bcs mine is manual e92 330i n52b30a and there are some differences, so little content on e92 330i on yt unfortunately but your vids on some parts helps me a lot... not trolling..
Yup e90 content is great! Honestly all your content is Amazing! Keep the videos pumping out!
Looking forward to the 3.08 LSD conversion video!
It is removed and replaced by the larger case manual differential with the numerically lower gears.
I had a 3.46:1 Wavetrac in my e46 and loved it.
Personally been running the 3.46 with the manual for over a year now, for my uses I enjoy it. Not a daily driver, and whenever I do drive it it’s for canyons mostly, so having the more aggressive gearing makes it fun. For a daily, definitely can get annoying at 3k rpm to do 75mph
I always bought manual 3-Series cars, but I have no regrets with my current automatic 2009 328i E90. I bought it this month and replaced the usual OFHG, tensioner, belt, front pads-rotors-sensors, bulbs, wiper blades, and brake fluid. My tech says it is in great mechanical condition, which I suspected from its like-new appearance. The Carfax verified a new valve cover gasket and I am keeping the Carfax current to give the next owner confidence to buy. Your vids are helpful and interesting so keep it up. My biggest interest is updating the media and phone systems.
Automatic kind of turns 328i with N52 into a really nice accord. 6MT is so much better unless you do a lot of parades or parking lots.
@@machtschnell7452 Lol. I hear you and they are worth the effort to find. An Accord? No way, the machine drives nice with just a pedal and brakes.
Me and my son love all of your videos!!!!
Thanks for watching!
Another Awesome video 👍
Banging background tune!
my favorite channel on youtube
You work so much on the cars you should really pick up a set of quickjacks...make your life so much easier dude! I got a set about 2 months ago and it's made working on the 335d so much more pleasant.
Your BMW content is the best man. Really appreciate all the informative vids you do. It helped me thru the years building my car and surely many others who watch. Keep it up man!
Love all of the E90 content! I'm currently building an E93 (2007). Upgrading the suspension now. LSD is likely next.
I have the same car. Curious what upgrades you might be doing.
@@Lopes12676 I'm planning on doing a full build from engine through the entire powertrain. I am currently FBO but running stock turbos. After I complete the suspension work and LSD. I'll do the turbos next. I'll likely opt for keeping twin turbo setup over a large single turbo. I prefer to have the power band lower reaching in the rpm range even if it means I lose a little top end.
@@the-next-gear3626 thanks for the reply. Good luck with the build. Hopefully I can follow your progress.
i have put e39 m5 lsd in to my 535d diff and it will outlive that engine. New plates etc. 2.56 ratio seems fitting for fast diesel ;)
Gears can make or break an experience. I experimented with FD ratios on my civic when I installed an LSD I love this car but i hate the larger ratios I picked and the car has just sat for months. This winter im swapping it all out for larger gears. I wish there where bolt in LSD options for my E92's front diff.
Really want to see you do the lsd conversion on this one. That’s going to be my next mod. Btw hope you are ok..haven’t seen you post in a while
Can you make a video review on the single mass flywheel you installed when you did the manual swap? I find it tough to find in-depth reviews on the conversion specific to n54/n55 powered cars. No one seems to mention things like how much the shifting effort changes. Or whether the clutch is super grabby or not. I had a valeo single mass flywheel conversion kit in my old e46 with the e60 shift lever and I really found that it took away from the refinement you pay for when buying a BMW in the first place. There definitely were some pros for spirited driving but a very unforgiving setup for city commutes to work. Basic things like driving over speed bumps had to be perfectly timed.
I completely agree. I did a manual swap on my AWD 335xi. And am now searching for 3.08 diffs as well. Because I daily the car. The mpg is trash with driving on high rpm. Car is on e85 so that makes it even worse. Yes power and is fun. But I don't think 3.46 on a manual car is worth it unless you are tracking the car only. Not for a daily.
Good to see the baby of the family back ,💪💪💪 how about rebuilding the old N54 that you swap ?
That's still in the cards.
Id love to see you push the n54 to its limits!🔥 80% of your viewers are n54 or old n54 owners. Do that single turbo build!

Great content
Cool stuff
He makes this look so easy
As someone who has a manual 335i with 3.46 lsd, I have to disagree with your analysis. Couple of things:
1. Your clutch based lsd isn’t brilliant. If you have a proper Quaife helical geared lsd, it’s night and day.
2. If you do track work, it’s so much more responsive with the 3.46 gears and you don’t necessarily “shift more” because you don’t always have to downshift to a lower gear.
I was lucky to find an early automatic with the large pumpkin and a bolted ring and pinion to match with the Quaife lsd. I find it much more fun than the 3.08.
Guess it all comes down to what you use the car for and personal preference. I also run the 3.46 w the manual and love it. Not a daily driver though, mainly for canyons and the occasional track day.
I was hoping you showed something about preloading the center support bearing during install
Sheesh I thought you were going to sell the e90 when I read that!
Upgraded turbo or even fbo e85 auto guys really should think of swapping to the manual 3.08
One it makes the wheel torque less so it's not as likely to break lose. But also you get longer gears so your top speed and usable power gears are much better. I've done the swap a year or so ago and it's Night and day and really a different car
I'm not sure if you did but per BMW manual you're supposed to preload the center support bearing by pushing it toward the engine then torqueing bolts
Good feedback.
I don't think that specific preload does much. Snug the bolts up close and move the support forward 4 or 5mm and lock it in place.
The important preload for "normal jobs" (not internal engine or gearboxes) is the preloading of spherical suspension bushings under load when on the ground prior to tightening.
I don't see really any difference in bmw driveshaft support longevity or anything if you just put it back up and that's it. I usually tighten front and rear and then torque the snugged up center. Ive preloaded them before etc and doesn't seem too important. Bmw also says to replace the caliper guide bolts every brake job. I doubt that really happens except at the dealer and probably half the time at that. And many other bolts too. Some are necessary or even best to simply replace and some aren't as important.
Bmw also says vacuum fill every cooling system.
Bmw is great not everything their shop Manual says is God.
If it was critical I think it would be well known as a catastrophe if you didn't push it those couple millimeters forward. It just isn't the case. Ymmv as the kids say.
Hey. I just recently did the M3 dynamic rpm gauge retrofit that you showed and I encountered a small problem. The motor itself works but the gauge moves too quickly. Its right at 7k rpm way before the oil is even warm. Any clue what that could be?
Hey man I really think you should put these cars in test for content like going down to drag strip
You should get that CES single turbo kit 😮💨🤩
Weld the diff and axle spacers. Best bang for buck setup. Drives completely fine normal driving. Axles spacers so you don't have the problem I did lol
Having a look on yout old re-used downpipe/midpipe gasket you may have an exhaust leak there... the after cat lambda probes are the reference for your wide band pre cat lambdas. In worst case you run to lean or to rich.. Maybe you will run into not set learning bits for your injectors (see Inpa) or / and your idle becomes weak. Just want to mention. Maybe I saw it wrong in the short sequence.
You had seen it right, no leaks but I'll replace them when I pull the exhaust back out to add the LSD later on.
i love your e90 man..
Oh man I was confused for second with the steering wheel. I forgot you swapped it out for a F-series.
I would love to see a CCC to CIC iDrive conversion video! Its hard to find any information on this, even though its been done
I'm just running an android head unit.
Hey man hope your doing well I just wanted to share my experience of my 08 335i with 138k miles. I got a letter saying the car needs a recall so I took it to the dealership and there were no problems it was a good day no problems and a week later while I’m driving completely turns off. Been down about a month. I’ve tried many things I don’t think it’s an electricalI problem. I think it might be the fuel pump control module. Any thoughts of what it can be ?
re: the 335i not being real comfortable off the line -- I'm trying to remember, what suspension mods have you done to the car? I think I remember you doing the M3 control arms up front a few years back, but it's been so long I'm not sure if that was it, or what else you did for it.
You can put m3 control arms and tie rods
Missed this car
Great content, thanks. But how did you manage that the speedo shows the correct speed, since the ratio changed?
The speedometer is calculated off the wheel speed sensors, which are unaffected by a diff change.
335i or 440i? Which one is a better driving experience? Apart from the steering feel of course.
The E90 is a great platform. You can add the M3 front and back subframes too.
My favorite thing about the E90 is the size, not too big but not super small.
@@VehicularDIY are you on stock alignment? That could be part of the reason the car doesnt wanna put power down
@@VehicularDIYTbh that's one of the things that attracts me to Audis RS3
Anything above 3.3 is only good for track, drift, etc. and even that needs a 6 speed. It'd be interesting to how it affects 1/4 mile times.
So from what I'm hearing a 3.46 diff will physically fit a car that came with an 3.08 diff? In otherwords if I have an 07 335i e92 the diff from a 2012 335i will fit but have different gear ratios?
a lot of people complain about gasoline bmw being slow of first gear, i have a diesel e90 330d rear drive only , it flies like a fighter jet, but i think that bmw diesel turbos are much stronger then gasoline one.
Not to mention the percentage of torque it's got to be noticeable!
Love cars in the southern states! No rusty welded bolts!
I hope my 2007 E92 335i has a bolted diff , would make adding an lsd so much easier
Hey man how can I tell if I have a timing chain issue I have 73k miles on my 2013 328i x drive & the dealership told me I’m not eligible for the extended warranty for the timing chain :(((
Do you know if a single piece drive shaft exist for the n54?
Try a ford 8.8 diff kit for your 335i it’s bulletproof, vehicle virals is running that in his 700hp 335i and i have it on my 08 335i with 457 hp. Just an idea 💡
Haha, you finally did it!
U managed to fix that noise on startup, what was it?
So when is the speedtech single turbo install video? 😉😁
TY
Can you do a video on the DME locking that the 2020 and after bmw have.
I think in a couple months the options are really going to open up on that. Hopefully via OBD.
I think its time for new rims on the e90 !
where is your mechanic shop in houston!
What brand LSD are you going to put in the pumpkin?
I’ll buy that diff brace .
how did you get that steering wheel ?
How do you go about dealing with the speedometer inaccuracies as a result of the diff ratio change or is the speed measured off he wheel sensors rather than the gearbox?
Wheel speed sensors 👍🏼
I swapped from a 3.08 to the 2.56 from the DCT. Gears are way too long for me so I’m swapping back to the 3.08 soon.
Yeah 2.56 would be super long, maybe good if you're running a big single and want to load it up on the highway but otherwise probably wouldn't be fun.
Better to swap in the DCT.
Did you do all subframe bushings and suspension? Mine feels awesome.
I haven't yet, I've done the diff bushings.
@@VehicularDIY makes a huge difference, sway bars as well.
Did you do the fronts and rear? I have not done rear bushings or subframe, I did just the front and it definitely helped but pushing the car it feels a little unstable at times
@@austinnelson5529 both biggest sway business available
And here I am tossing up between my 3.85 vs 3.15 on my manual 😂
I asked this question before can you please tell me where are you putting jack under when you lifting both front wheels at same time 👍🏻
In the front on the black metal brace that bolts to the subframe and on the rear on the differential.
@@VehicularDIY it’s safe to put jack under differential ??? It won’t crack
@@mikimiki195 iirc the owner's manual advises to use the diff as the center rear jack point. I think it includes a warning about not setting it on the lip of the diff case - *that* can crack, but avoid that and you're fine. Even has a diagram for it. If it's not in the owner's manual, try the workshop manual, it'll be in there for sure.
Given how much work you do on your car underneath, you would benefit from some sort of hoist surely.
I always like the content on his channel. But he said "when I'm pushing the power on this car it feels like I'm just hurting the car". Or something almost the same as that. But if he is going to go with a single turbo set up won't that just feel like it's hurting the car even more? Maybe I don't know exactly what he means by that.
What are your thoughts on the 335 vs the 440? Is the 440 the same but better or is it a different experience? How is it interior size wise?
The 440i is a pretty different experience, feels more related to the G20 M340i I had than the E90. Interior wise and driving dynamics it feel smore like a GT car. The engine is great.
How much will you sell everything for?
Let's do a budget built motor (just rods & pistons) I'm sure plenty people would chip in.
Will an M3 differential bolt up to the rear subframe? I have an 09 small diff and thought about replacing it with an m3 but read that it wouldnt work.
I believe you need the M3 subframe as well as M3 axles, and then you’ll need a custom driveshaft that’s a hybrid in between the 335 and M3 one. I am planning on doing this to my 335 in the future
Which LSD are you getting? Got my Quaife last week and having second thoughts about not getting a Wavetrac :o
Why second thoughts on the wavetrac? Did you consider an m-factory?
@@matthewweisdorfer7757 Supposedly wavetrac is better in some situations where one wheel is in the air, dunno if that ever happens though lol. I was considering mfactory first then found a quaife for same price at schiedmann.. easy choice there.
No 1 option: Get a ZF 6 speed, with a 3 clutch LSD(4:1 ratio), you will have the best fun out of that car, if you cant find the diff ration, just get a smaller rim size
No 2 option: Getrag 6 speed, with a progressive LSD(racing diff conversion kit) current ratio
all about acceleration in my end though
SINGLE TURBO YESSIR
Can you do upgraded ebay turbos?
I'm running upgraded twins, Dynamic Autowerks Stage 2+. To be honest given the labor involved I wouldn't want to gamble with 17 or 19T turbos unless you plan on adding an upgrade kit before ever putting them on the car at which point it might make sense to spend a few hundred more and get better quality turbos.
Wouldn't it be nice to have a dual clutch auto that could used manually with a clutch pedal when you felt like rowing the gears?!?
Thanks for sharing. Sounds like you did the right thing here for your driving enjoyment.
A DCT would be cool but I'd prefer the manual based on how this car is setup.
Dual clutch means exactly that; two clutches which are impossible to control with one pedal, let alone even two.
So neither is it an automatic. It is a manual with computer controlled clutches and shifting. The automatic shifting feature is just an additional software feature.
@@machtschnell7452 yeah, the clear solution is to own a manual plus a dct model!
I’ll have to tell my wife…
As a fellow BMW owner, can someone tell me what's that green blinking thing on his gauge cluster because mine doesn't have one.
I sprung for the option, but the fluid is pretty expensive.
@@rwsavory
Thank you know what I spend enough a year fixing the car.
You have already put alot of work on this, I think it's a good time to say goodbye to this bad boy. You may get f80 or so ( something close) and make content on that ( very unmaintainted).
Yeah in a way I have we have the G80 and F36 on the channel.
@@VehicularDIY Right, you have already started these projects. Well sell the E90 :D I am on your side dude !
Did you ever figure out why it was making that bad sounds when starting it after you converted to stick?
Yeah it was just the teeth on the flywheel needing to mesh with the starter gear. It's pretty much gone now.
I did a 135i manual conversion and I had no such noise.
I think you are really need a hoist in your garage! It will change your garage time dramatically!
Yep!.. and not only so much safer, but gives a whole lot more scope and visual involvement for subscribers watching the videos.
Definitely upgrade subframe and differential bushings at the same time.
Drexler clutch or Torsen inertial LSD?
Recommend the MFactory inertial for street.
Single turbo us great at the strip, not so much at the track nor especially on the street.
So the far the diff bushings have been upgraded.
St please
How do you recalibrate the speedometer
Unnecessary. Speed is calculated off wheel speed sensors, which are unaffected by a diff change.
@@ModMINI I have a auto and it is squirrely in 1st 2nd and if it’s cold 3rd below 60⁰F was thinking about going to a lower rear gear.
@@andrewf8486 That seems like overkill solution. Get better tires, get LSD, or apply less throttle until there is no spin.
