N54 VS B58 watch this before buying one in 2023 

When my n54 dies, I'll be looking into a b58 conversion. E92 just looks to damn good!

One of the best and most useful bimmer comparisons, good looks!!

ive been building n54s forever, and b58s for about 4 years now. some advice, build an 54 car before you venture into the b58 cars , for 6k you can build a wet sleeved n54 long block, fire finged and setup for 625 studs, stock n54 head, upgrade valvesprings for $600 and that block will handle 1000whp all day long. delete the index 12 direct injection on the n54, its CHEAPER to buy maxxecu standalone ecu with harness and some port injection than it is to replace index12s. you can 8hp70 swap a 335i for under $4000 and upgrade cluthces in it for 500 bucks, hold 1000whp all day long. my 1100whp 8hp75 335i outruns a 1100whp b58 a90 (i own both). you can literally run just as fast as b58 with an n54 for 1/3 the price to build for parts, and the cars are literally dirt cheap. n54s are cheap as k series to build now per cylinder. im 30-35k into my 335 including cost of the car and half of that is the pure drivetrain solutions trans build and theres not a b58 car on the planet other than mikes a90 that can come close to my car. this winter im going 7.70s

N54 gang here, but I love the b58. I'd say, you are a very patient man for keeping the boost conservative until you have a built engine! Most people would want to send it, but I also don't want to blow my engine up, so I think I'm going to do what you do, and keep my car under 24psi/550hp when I upgrade my turbos. The turbo upgrade is $4-7gs easy, but to truly take advantage of it, you really need to fork over another $6-8gs to build the engine (if someone else builds it) so it's a game of, "how patient and mechanically sympathetic am I?"

Juan great video, love the cars in the background.

11.30 - I've owned camaros, etc and just in the past couple years got into bmw's, really great cars if you keep up with them

I had the same set up on my old n54, single ftw! I'm gonna be buying an m340i very soon, and I can't wait for the power/great reliability of the b58!

a great video from a small channel. hope your channel grows

Brilliant video thanks 🙏

A lot of people really love the ZF auto on the b58 cars. It can be customised so much, feels very stable up to 700 hp and feels a bit like a dual clutch

You should look into a cam. I hear it’s going to make the awesome cam for the Anthony Ford games like 40 hp just off the cam and torque. And sound better.

If my n54 blows I'll be looking at a b58. Plan to drive it till no more parts available. Seen the potential of tuned b58 just insane.

11:32 need this as my next car

From the information I've heard and seen the manuals in these cars can handle over 1000 hp easily with a good clutch. Mind you you do have to put in z high quality clutch if you want it to go over the 700hp or so mark.

I been thinking about getting rid of my pure stage 2 335xi and going to a b58. But damn it's so hard to sell off one of the most sexy cars ever built. The feeling of connectedness with the road in this car is second to nothing I have ever driven. With awd if puts it down from 1st like a boss. I can't imagine using much more than this on public roads lol I don't know of much that can hang around here. I have pretty much rebuilt everything at this point, but we know how it goes lol we get bored and want to build something again.

How the n54 holding up? What is the n54 making to the wheel?

I have a e90 N54 top mount with a 6266. Simple build DI only on E30 pushing 20psi. It’s fast enough for the streets. Pulls crazy hard and beats 90% of the cars on the street. I don’t need to push over 700 hp, I’m happy with 500 whp safe reliable power.

11.30-11.35 I’ve owned a n54 and did everything myself until recently getting into the B58. IMO the B58 is way less of a pain to deal with than a N54

I believe bearings and other crucial parts of rotating assembly are coated/treated to accommodate stop/start on b58. A by product of this is better longevity I guess?

11:31 Have an E90 & E92 N54. Might sell the E90 for a F30 B58

11.30 the is is my dream car

The 6 speed 45bz in the 340 won’t take more that 600whp long. 53bz in the n54 is known to take 1000whp without being cracked open. Sucks there not stronger manual trans you can swap into a b58 since starter is on the bottom. Hope the Supra trans hood or might have to get a 6 speed attached to a n57

Any difference with 2016 n54

11:30-35 e90 335 FTW! in all seriousness both cars are extremely cabable but god what i would do to get one of those zf 8 speeds in my e90 😂 that trans is really what makes the newer bimmers worth it imo

When you setup an n54 properly, it will make just as much power and be just as reliable. The suspension geometry is EXTREMELY similar (almost the same). The n54 bang for buck is unbeatable. Also n55 EWG cars are pretty damn good too ( f series/late year motors)

N54 was on the 2013 335is. I think it was on the 2014 Z4 S Drive 35is too, but without the pony radiator as there never was enough room. F30 okay, but for a B58 I would go for a G30 340i either the requisite cold pack to get the LSD. MFactory LSD with M3 bushings and arms were necessary to get handling where I wanted on my 335is. Seats are better in the E92 and the size is right compared to later F and G versions unless you haul 4 people a lot.

11:30 - 11:35, I've owned my very own E92 335i and regret letting it go.

11:30 Nice video. I do have an N55 planning on Rod bearing update. Do you use coated or original bearing?

A month ago I got white on whites interior e93 n54 auto from old gentleman for 10k $ fully stock clean title car with 43k original miles, it’s in brand new condition… I feel guilty to modify it lol. Most likely will keep it stock as weekend car

Do you think a 2016 340i 6mt with 122k worth around 20k? One is for sale and I’m trying to get him down as much as possible.

Hi Juan, Do you have any oil consumption on the B58, and what kind of oil have you been using?

What's the power limit of the manual transmission assuming you have the Motive twin disc clutch?

The next video should be about the cost of the mods

So tempted to sell my N54. It’s giving me a plethora of issues that I’ve constantly had to pour money into. Now my turbos are showing signs of failure at 74k! Doing my trans service on my ZF6 soon, then turbos. But really tempted to just sell this and put a down payment on a B58.

b58 doesn't feel like a race car setup its too modern. I enjoy my e92 full race car setup currently pushing close 700 to the wheels with 6266.

The current major problem with the N54 is those damn direct injectors. $3.4k USD for index 12's is crazy, and if you buy any below 12 they will go to sht.

So basically if i had the money get the B58 but if im on limited funds go with the N54😂❤

The dots were at 11:31

11:31 brother

We need to have a chat

Both can make 1000 with pistons, rods, and head bolts

cant forget to mention the b58 is closed deck whereas the n54 is not, the b58s block is actually designed around the diesel variant which is why its capable of 1000hp+

13:58

Index 12 injectors are $450 per. Just insanity. I've owned a fbo 135i, I'll take a B58 all day.

B58 is fast and reliable, so easy to work on compared to others cars I've owned

b58

11:30 😁

It ain't N54 VS B58 but it should any Porsche

Dude you’re comparing your own personal feelings vs what the actual cars can do 😂😂

😂😂😂 I'm not buying that B58 is trash

The ZF with XHP stage 3 is faster then the DCT
