It's time for our first ever non-Japanese engine on Iconic engines, and we are starting with something pretty special, the engine that is likely BMW's best ever 4 cylinder. The legendary S14 four cylinder engine that powered the BMW E30 M3.
The BMW S14 engine is actually a Frankenstein engine, this being the case not because BMW was cutting costs, but because one of the greatest engine designers of all time, Mr. Paul Rosche had already designed so many great engines for BMW that there was no reason to work from scratch. The goal of the S14 was to turn the BMW E30 into a DTM champion. Initial plants to shove a straight six into an E30 M3 were abandoned in favor of a lighter four cylinder that could rev higher. A lighter engine meant lower weight and better weight distribution and balance which can be a lot more important than outright power in racing and motor sport.
So the BMW s14 engine got an M10 engine block, an M88 cylinder head (with two combustion chambers amputated) and some sexy ITBs. The S14 and BMW e30 M3 combo were so good that the BMW e30 m3 became the most successful touring car of all time. When it comes to touring car championships and Group A racing the BMW e30 m3 won pretty much everything.
When it comes to the specs the S14 engine has 93.4 mm of bore and 84 mm of stroke. This gives us an over-square engine design which makes sense because the BMW S14 was designed to spend most of it's time in the high rev range. However, the basic 2.3 liter version, S14B23 wasn't the only available displacement for the S14. Italian and Portuguese markets got a 2.0 liter version which was created by reducing the stroke, while Europe got the 2.5 liter EVO 3 engine at the end of the BMW e30 m3 production run. On top of the cast iron M10 engine block we can find a aluminum alloy cylinder head with dual over head camshafts (DOHC) and a bucket and shim on top of a bucket pushing onto the valves. The camshafts are chain driven and the chain is a good dual row design which doesn't cause any issues. The same can't be said about the S14 chain tensioners, BMW used several different versions and some caused problems with chain stretch and wear. This is why many S14 owners choose to upgrade to the S50 or S52 chain tensioner. The camshafts have 240 degrees of duration and a very impressive 10 mm of lift on both the intake and the exhaust. The power output of the BMW s14 ranged from 189 hp to 235hp for the EVO 3 engine. The US market received only the 192 2.3 liter S14 engine which made 192 hp and had a catalytic converter.
When it comes to tuning the bmw s14 engine really is a racing engine adapted to use in normal traffic. As such it's incredibly fun to drive hard even if you don't tune it. You have to understand that this engine needs to be driven hard to be enjoyed, it makes all of it's performance in the top 1000 - 2000 rpms, so if you think it's slow or doesn't have any torque you really are missing the point. How to get more power? For mild tuning you won't be touching the intake or the exhaust manifold because you really won't gain anything there. Some mild camshafts will can get some gains, most will be gained by replacing the stock Bosch motronic ecu with a modern standalone ecu, if you know what you're doing with the fuel and ignition maps you can get some horses and also an aftermarket ecu will allow you to get rid of the stock flap style air flow meter which hampers performance. What about big NA power on the S14? Sure, just do what BMW did in the DTM. This will make you broke but you will have a road illegal engine that's massive fun. Wild cams, throttle slides instead of plates, crazy 4 into 1 headers, porting the intakes, increased displacement, increased compression, dry sump, and you can expect 350 hp. What about a turbo s14? Sure it can be done but be ready that the car will loose massive value. An alternative is to swap something into your e30 m3, get big power out of your system, conserve the s14 and then swap it back when you get bored of the s50 or whatever else you swapped in there. Supercharged S14? Yeah you can do that too, but good luck finding the parts.
Rap translation:
I have an awesome cylinder head
What are you waiting for, press the start button
I'm the fastest engine on the Hockenheim
I'm so fast there
Nobody can overtake me
My name is the BMW S14
and I'm the greatest engine you will ever see.
It all rhymes in German....I swear.

you should do the M50 family of engines too. M50/52,S50/52
m50 is life
Please
The M50 family is peak BMW
Up😁😁😁
M54 and s54 are great 2 haahha
Sexiest phrase ever is “unlimited development budget” a la lfa, Carrera GT etc.
This is gonna make your channel, just wait till the algorithm picks it up. You never know, you could end up getting a job on donut media and move the series over, with the ability to physically show us the engines and the cars they were in. Keep up the fantastic work, your truly class leading with this series.
Basically bumper to bumper lol
I apologize in advance. You’re
That's a great compliment. 😊
I would enjoy his antics with James. 😂🎉😂
The best thing was in the DTM they did make up to 380-390HP in qualification trim on normal Pump Gas.
No Race Gas was allowed
My dream build would be a 1974 BMW with a S14B23 tuned to around 300HP
Greetings from Germany 🇩🇪
There were no S14's making that power, the most powerful S14's NA max out well below 350HP, around 320 or so.
@@Mantenner thats bullshit. "By 1990 the engine capacity was rasied to 2.5-liters and a larger version of the S14 was prepared that could produce 340 bhp." And in modern time, i bet you could get a punch more. AND with short google run i found few 360hp s14:s
@@TopiAS06 Depends on whether you count race engines that have all upgraded internals and need to be rebuilt every few hundred miles.
A stock S14 might produce 360hp, at around 10000rpm...for a few seconds, then you get a hole in the block.
@@BigUriel so if race engines don't count then 2jz making 1000hp don't count, or the claim that 4 banger Honda motors making 1000hp+ don't count either....... Those are race engines as well.......
@@Mantenner that's public data man..... Bmw factory and Schitnzer themselves have made those claims.....
Quick anecdote from an engine book I've got. From an interview of a BMW F1 race team engine builder, they would go out to wrecking yards to find old clapped out sedans with the highest mileage they could find and pull the M10 blocks for cores. The thinking was that these engines with tons and tons of hours on the clock would have all the casting stresses out of them and would hold up to grenade-spec boost the best.
Seeing as these cars were laying down 900 to 1500 horsepower with factory stock iron blocks and NOT blowing up they might have been on to something.
That’s super interesting thanks for sharing!
What engine book if you don't mind me asking?
@@deltas4764 Its just called "Legendary Car Engines" by John Simister. Printed by Motorbooks.
Tons and tons of photos of engines in various stags of assembly and lots of interviews with restorers and historians.
Picked it up years and years ago. Highly doubt its in print. Makes a fantastic coffee table book.
@@deltas4764 amazon has it for like $9.00 U.S. and up.
So they took junkyard engines und turned them into rocket engines with 1200-1400 hp and 5 bars of boost?
You are a cool dude. Flippin AEM even thought "hey this guy is so cool we're going to sponsor him". Like bro AEM is the best, I run nothing but AEM
They really make top notch stuff, and I'm honestly not saying this because they sponsored this series. I have their wideband in my AW11 for more than a year now, and it's been nothing but good to me.
They also sponsor many different makes and model project cars and teams
(OO=[ ][ ]=OO) my first true love.
Whoa, that really looks like an e30! Pretty cool.
[ OO=[||] [||]=OO ]
"Turbos in toasters", I just laughed and laughed at that line. I've secretly always wanted to put a turbo on a lawnmower engine.
I need help...
But I think I'm in good company.
Love your vids!!!
It's a bit hard to make it work because the engine is too small and you just can't find a small enough turbo to make it work. Nitro on the other hand....
Absolutely BEST sports car I ever owned. I loved my E30 M-3. I put 100,000 miles on it after I bought it at 75,000 miles.
Very sad we didn't get this M3 in South Africa. We had to create our own homologation special, the 325is, with the Alpina 2.7 M20 engine. This was to compete against the South Africa only Opel Kadett Superboss with the Delta modified C20XE, stock with Getrag LSD gearbox amongst other thing.
Also interesting is that South Africa also made a 333i with the M30 engine also helped build by Alpina. We also made the Opel Kadett 200ts with a C20LET and 6 sped LSD Getrag which debuted with 160kw (215hp) in 1994.
This series is impressively informative, keep it coming 👍
I see a new Iconic Engines video. I click like.
As a German I am actually impressed by your language skills... It actually was near flawless....
Bi, or multilingual. Sadly, many Europeans speak English better than many Americans.
@@frankmiller95 And some English people ....sadly
Great vid, I have a 2.3 and a 2.5. My fav engine. It loves life at the edge! Long live the E30 M3!
Please do the BMW m50-m54 family of motors! Right meow! On a side note your channel is a huge breathe of fresh air compared to most of the garbage on youtube. Thanks Boss
Great video. We still occasionally see E30 M3 track cars come through the shop with built 2.5 liter Evo engines and aftermarket engine management (to eliminate that horrible airflow meter from the stock setup) and they easily produce 275+ whp using race gas on the chassis dyno. That's incredibly impressive for an engine design whose genesis was nearly 40 years ago. Fully agree with naming this engine one of the all time greats.
I have always said the thing that turns me on most about 80's and 90's cars is homologation, cars that were designed with racing in mind and offered to the public, I mean as a born petrolhead what more could you possibly ask for?
My S14 is being rebuilt right now. Its looking awesome.. Gonna do a youtube post once its done..
I absolutely love driving the M3. What he said about it was totally true. Anything below 4000rpm doesn’t count in the E30 M3.
Above 4000, its heaven.
To be fair the BMW M1 was the first M car that started this lineage. Though arguably the 3.0 CSL was the first M car, despite not having an m badge. Then the M535i, the M 635 CSI, the M5, and then finally the e30 m3. Though iirc there was a updated m535i somewhere in there. Interesting also to see how much they experimented with M placement and the spacing before and after the numbers and letters
No, I meant the M3 lineage, not the whole M thing obviously.
driving 4 answers ah my mistake, it wasn’t obvious to me, but I’m just waking up.
I only got thru 100 comments, so I hope I’m not repeating.
I started playing with BMWs in 1972 while working in a body shop that did the work for the first dealer in upstate NY....when they were”British Motor Works”.
In 1982, I met Jim Rowe...founder of Metric Mechanic. Wow. 40 years of tireless R&D on BMW engines / trans/ diffs. Now that I’m retired, i fly out to MO ever 3 months to work in the shop and improve my knowledge and skills.
I work for free room and board for the week. It doesn’t get any better than that!
If you have a n S14 project, give him a call.
40+ years of improving bmw engines.
I love these videos and how in depth you get. I appreciate the extensive research that you must do to bring this to us. Keep em comming! And thank you.
You can remove the flap MAF with a heated wire MAF. There is a product called a "MAF translator" which interprets data from a new heated wire sensor, then sends data to the ECU that is exactly like the flap MAF. Some call the OEM sensor a "VAF." It is good for a few horsepower by itself. I think some people mod their Datsun 280ZXT to accept a 300ZXT heated wire MAF for example.
23:14 There is another way. Have you heard of offset grinding? By grinding the crank throws off center and then welding them up, you can lengthen the stroke by a few millimeters.
29:00 Plus, with 10:5:1 or more of compression, you couldn't run much boost anyway. It would probably be required to buy lower compression pistons.
hi mate...i think its a good idea to post a video on Paul Rosche, the High Priest of BMW Engines... alias camshaft Paul . He regretted not being able to add a turbo to the S14 but the race regulations had to be followed. That would have made the E30 M3 an even more powerful sacred beast
9:40 that’s my car bro S14B25 😂
I'm only at the 6:00 mark and my head is spinning with information. Well-presented information. Driving 4 answers: I'm guessing that you have a significant background in engineering (and it shows) but your ability present what you know in this very clear, concise, and entertaining manner is impressive and is what makes you one of the youtube automotive greats! Thank you again, keep up the good work, and be prepared to receive your honorary PhD in "Enginology" . This is excellent!
I love how mechanical and raw this engine sounds
I worked in sales for a BMW dealership in Peabody, MA, USA, when this M3 became available...we sold every single one we could get our hands on at full MSRP! What a treat, not knowing it would be an icon like the M1!
Im late on this man’s channel and I’ve watched quite a bit of his content.. This guy needs to get paid. That’s it.
Nice work my man!
Dude, that German rap was awesom!
Love your Iconic engines clips. Thanks for making them.
Greetz from Holland
I Love your Iconic Engine Series! Yes please make a Paul Rosche Video. And BTW your German is pretty good. Greetings from Hockenheim Germany
I grew up watching Pokemon on RTL2, that's how I picked up most of my German... aaah good times. Wow, Hockenheim, not many cooler places where you could live. Guess this video is right up your alley :)
@@d4a oh yes good old RTL2 times. the Kickers was awesome aswell. Yes its pretty cool you can make drift trainings or rimeattack driving in Hockenheim but Nordschleife is not far aswell. I drive a z3 coupe with the M52B28TU as a daily a d have a S13 200sx with the CA18DET Engine. A awesome Engine BTW called little RB. Cast Iron Block and Oil cooled Pistons by Oil spray from the Bottom. It was to expensive and replaced by the SR20det.
I had 2 BMW'S in my 20's
My car the 1982 323i 6 Cylinder with big cam (Import to AUSTRALIA) This was the best car to drive fast in the 90 it would eat v8's for breakfast, lunch and tea!!
I love that car
My partner's car was the 1983 320i I was told had was the s14 motor
Awesome video love watching Your content
I love this video. I think it captures the true automotive BMW enthusiast perfectly. The M designation was the marriage of sport and civility that we wanted.. desired? Needed.
I'm going to share all of this new information with all my car friends. I'm officially a little smarter about cars.
Reminds me of what people think of the s2000 when they first drive it under 6k rpm
You killed it with the rap! Super cool!
That isetta was SICK!!😅
As a german i have to say your rap was really good. Keep it up man!
This channel's content is wayyyy better and more in depth than most youtube channels about learning the history of cars. Fucking Donut Media sounds like they read off of Wikipedia with very limited fundamental knowledge about the topic.
Keep killing it with the knowledge!
Man I love this channel! I can’t wait till the next episode
How can you not love a man who can appreciate what makes a truly great engine block?
My wife loves me .....but not cuz of my appreciation for an engine block 😆
Having driven a tuned s14 (I admit I didn't go over 7000rpm, I am to afraid of breaking something), I wouldn't want to own one. The car is amazing, but there is no point in having one if you don't rev it to moon, which with an engine worth 3 years of rent I wouldn't want to do to often. On top of that, the s14 is 3 times as much as an s54, imagine how much more fun you would have with an s54, knowing you have 2 more ready to drop in when you throw a rod!
I love all your videos so much…the content is incredible but its your attitude and the way you look and think about cars that I relate to so much.
One small correction, it was the S88 engine in the M1, and M635csi. Unfortunately, my own M635csi needs an Electromotive system because the OE one has injector pulse issue we cannot figure out how to rectify.
Other than that, your videos are excellent, certainly among the best, if not very best l've been fortunate to find on YT. As a former BMW mechanic and an instructor in a different field, l cannot praise them enough. Your English is also better than many native born Americans, and in these videos, perfect.
I have only had BMW E34 M5 3.8 with S38B38 engine. Stock power 340 hp and 400 nm torque naturally aspirated. It’s similar type motor as S14 just six cylinder inline with larger 50 mm ITB’s and larger valves and 90 mm stroke. It would be great if you could do a video of M88 / S38 type engines. M1 race cars had naturally aspirated six cylinder 3.5 liter motor versions with around 470-490 hp power output at very high rpm for inline six at that time.
people who thinks this car is slow, the wanna drive like 400hp+v8, turbo car, or dont know how to drive it. its a car that needs to be high revd and keep the momentum up
I love how you switch on changing "accents" when speaking
I’ve worked on a few and driven several. I used to work as a mechanic at my uncles shop in Los Angeles. Never beat up the car just test drove after repairs were maid. I ended up purchasing 90 BMW 325 because of it. Completely rebuild the whole thing, sold it for cheap to a youth pastor that really wanted it. He then loaned it to a member from church and crash it 🤦🏻♂️. I wish I never sold it.
Dem pastors... Never hand them sporty beemers 🤣
And just like that, I have a new favorite series.
The people that complain about these things being too slow and not fun are the same people that complain about the S2000 being slow.
You take something tuned 100% for the high end and drive it like a tractor and it's going to be slow. If you don't hit limiter at least sometimes you aren't going hard enough.
i usually skip the rap even though it is kooky and fun. but i had to hear the german one and it did not disappoint. you should do them in german from now on.
Hey, your german sounds very good ❣️👌🏼
Love greeting from Berlin 😋
Im dead serious, they feel like they have less power down low then my gf's 1.6 60hp vauxhall, but i love the way the power rolls in and the sounds are insane.
its a +200hp 4syl from 80´s its a engine that needs to be revd, what did u expect?
The S14 I forgot to adk for, only had the M42 engine in a E30, was fun to drive even with low power, the engine liked the revs and the gearbox was great.
So I want to ask, please bring a video of the M42/M44 maybe compare and as always wanted to see the Ford Duratec, the 1.7 Zetec S and the OHC Pinto ✌
Nice video
PS: Your german is really ok 👍
The M42, Race Engine was the S42
M42 stroker builds
Crankshaft from m44(1.9l) or m47 a little more involved process and this link will show some of the similarities in other parts
the325is.blogspot.com/2011/12/bmw-m44-engine-to-create-bmw-s42-euro.html
More mods for lightening up the m42
grassrootsmotorsports.com/project-cars/1991-bmw-318is/project-bmw-318is-lightening-engine/
M42 is a wonderful engine, currently building a turbo m42 for my e30 with around 300hp on all stock internals. There's plenty of mods for these motors and they have a ton of untapped potential from my own findings and many others.
Thanks AEM
A side note about the M12 Formula 1 engine...BMW motorsport took the raw/basic blocks and left them outside to age/cure them..( before assembly of all the components )..It was found that exposure to the elements actually made the blocks harder...
I owned an E30 M3. I can confirm, anyone who thinks they would love to drive one will be very disappointed. I never took it on the track so can't comment on that.
All I can think now is how many times someone mentioned an S14 and I thought they meant Silvia/Skyline
Nice! Mine s14 turbo engine as Pic in the movie, the purple turbo one.
Performance bmw cover car?
@@n.c4831 yes also!
The good old days of race on Sunday, buy on Monday.
this series has been awesome. love all the techs and specs
I love this channel and I'm not even into cars!
Yea i was waiting for RICO's "Rock me Amadeus" to start playing in the background.
Great channel and thanks for sharing. I’ve always loved the E30 M3
love that Mercedes S190 Cosworth @3:40 😭😭
You’re a master bar none, best content!
You should review a BMW E30! Great cars🏎
Would love to see a video with the m54
I'd love it if you did one of these on the BMW M57's. Gotta get some diesels in here!
Please please my friend...do one video explanation on about alfa romeo 4 and v6 cylinders ever famous in the story of the motorsport. You really can’t forget of those great engines. We all counting on you for this video. Ciao
I think the M10 was the first Formula1 turbocharged world champion! pretty iconic...
I love this series! More bike vids as well please :D
Need to do the M3 S50B30/32 Euro or Nissan Fj20et. Great video mate
Both of those will be covered soon! Stay tuned. Thanks for watching :)
Hi, love your videos, I have owned one of these cars many years ago, I would love it if you did the Nissan vg30t engine single cam ... I had one of these in the late 80s it was in a z31 and was a factory turbo Nissan fairlady ... in the late 80s we modified it and was proving 450ho at the wheels and was for a long time one of the fastest street cars in New Zealand.
Cheers Pieter
Excellent explanation at 19:30, it's drivers car. :)
Awesome content man 🔥💪
Would love to build this engine and turbo it as a replacement for my fa20, ITBs make such a difference especially with a naturally higher reving engine
The s14 also powered the 320is. With lower displacement 2L instead of 2.3 or 2.5 like the m3's
your german pronounciation made me chuckle. sounds good though. great video series. this and the video about snap oversteer are the reason why i subbed your channel
That rap was sick, sick I tell ya
the 635csi still got the m30(b35) engine - only the M635 got the M88 of all e24's
The early 633 got the rare M90 which is M88 block and internAls with M30 head and a sick intake manifold. My fav non M BMW engine.
Very comprehensive video, thanks for doing this great work. Please consider doing the VQ37VHR
The video we all wanted and needed! And by “all” I mean the people who desperately want the e30 m3 but probably never be able to afford…😅 me😂
I think the list of people who are unable to afford them nowadays includes almost everyone 😁 they're crazy expensive now.
Great review. I would argue the Honda K/F/B series engines are better, but the s14 is no doubt a legend.
Just throwing it out there again, VW G40/60, or the VW AFH not the best nor most iconic but imo often overlooked, a neat 1.4/1.6 16v that can do pretty much 4AGE things :)
Fantastic video. I can't get over your knowledge of the S14 and engines in general. Keep up the good work, but I think I'll keep my S85 where it is for the moment.
m30 engine is such a fun motor to boost. It has all the pros of the m10 but with two extra cylinders and the benefit of being plentiful and in the full range of BMWs from the 80s.
I've got two e30's one has a m52b28tu and the other has a Euro m3 engine turbo
Did you swap it yourself? I’m currently swapping an M52TUB25 into my E30 estate! I’d love to pick your brain about the build
You got to do an iconic engine on the s54 e46 M3 engine.
nice video, deserves more vieuws!
Thank you so much for doing these Videos! Gute Arbeit mit dem Rap xD Hopefully we can get more german engines down the line... But before those i'd love to see the F20C from the S2000! Another return to the insanity that are japanese 4 cylinders.
D4A is undercover German😂
I want to see a race between a track ready 1991 442 and a E30 M3 Evo1. They would be about the same weight, if the 442 were track prepped. Both, 2.3L Inline-4s with similar output. (S14 having the advantage, unless the W41 was slightly modified).
They weren't at all competitors, but they're both unique in their own way. Moreover, a race between them would be equally unique and cool to see how the differnt approaches would compare on the track.
Have you done anything on the first V8 BMW M5 engine the S62? I once had a 2002 M5 and what I did to spruce it up was re-flash the ECM, eliminate the screen and plastic grating inside the Mass Air Sensors as per Dinan's advice coupled with K&N air filters and install a stainless steel Borla Catback exhaust because BMW for some crazy reason crushed the exhaust pipes down to 50% in diameter right in front of the differential increasing the backpressure. I suspected they put these band aids on the car to limit the horsepower to 400 hp. I also replaced the dual mass flywheel with an aluminum 13.5 lb. flywheel and Kevlar high performance clutch. The engine revved like an air tool when I did that. With all of the resulting increase in power and response I had to send the pressure plate out to maximize the clamping force because it would slip under hard acceleration. The clutch and pressure plate is was a flaw in my opinion of the E39 M5. I also ran into issues with the differential as I had ripped the anemic brackets off that held the differential to the frame and had to reinforce the brackets, another flaw of the E39.
All the fun occurred however when you pressed the DSC button disabling the traction control, the car would be all over the road in the first 3 gears. It was truly a sleeper if you didn't know what an M5 was.
How about an episode about opel CIH engines?
Please do an iconic engines video on the 426 Hemi, aka the elephant engine!
You should do one on the BMW boxer produced from '69-'94. Or how about the M-B OM617?
Episode on the B58 please!
One does not simply homologate a straight-6.
