What is the greatest pre-’90 six-cylinder engine ever?

A few weeks back, we asked you what the greatest pre-1990 four cylinder engines were and then shared the correct answers. Some of you dissented and claimed we were off, but it seems that most agreed with our choices. This week we move up the range to six cylinder powerplants. At this point I’m sure the Porsche-philes have already skipped ahead to stuff the ballot box, but in case you’re still reading: we’re aware of the flat-six. Yes, it’s a great engine. Perhaps, just for the sake of making this list more interesting, you could offer up more than your choice for the best variation of the 901? You’re already typing ‘Porsche 901…’ aren’t you? Oh well, just make sure whatever motor you pick, it’s pre-1990!

But please, when answering, let us know why you chose what you chose. And if you want to know which way we’re leaning, click here (after commenting of course).

Without a doubt it has to be Alfa Romeos Busso V6

It’s a no brainer question when asked about the best pre 90’s six cylinder engine ever. The 3.0L V6 Alfa Romeo Busso Engine, the 3.0L maintained the gorgeous note of the original 2.5L but just amped up the performance to where it craved to be. This Engine was a work of art straight out of the box, no modifications needed. My Runner up engine would go to: Mercedes Cosworth 2.5L Engines in the 190E Evolution – An absolute cracker of an engine that many of the members in the comments have seem to have forgotten! And my dissapointed engine award… Read more »

Sorry to be boring, but its clearly either the BMW M30, mainly for its longevity of production, component quality, tunability and the amount of Touring car championship victories. Additionally of course it was also the basis for the M77, M88 and S38 derivatives which produced class leading power outputs from the mid 70s to the early 90s. Name another engine which produces 92bhp per litre by fitting an exhaust and chip, like you can with the M88/3? The Porsche flat 6 of the 80s is another strong contender, but it wasn’t really that available to the masses, and I would… Read more »

I’m gonna vote for the Nissan RB series motors IE RB20DET, RB25DET, and the incredible RB26DETT. They just barely make the Cutoff of 1990, but I’ve never seen such a great line of straight sixes. They’re immensely strong, reliable, and smooth…and the sound.

Alfa Busso V6 for sure

Alfa V6 Busso. Beautiful sounding engine and it was successfull in racing arenas as well.

Mopar Slant 6! The “Buzzin’ Half-Dozen” was about as bulletproof as you could get, a unique exhaust note and incredibly stout (aluminum design, cast in iron for cost savings)

A serious case could be made for the BMW M88 (certainly the first engine that comes to mind for my vote… air cooled flat 6 taking 2nd place) particularly when you consider its variants and the lineage it went on to produce. I’ve already seen a nod here for the M30 which is/was a titan of a power-plant that already received a nod as one of the top engines of the 20th century… and the block upon which the high performance M88 was based.

Having owned both an 911 Carrera, and an E34 M5, I can assure you that the S38 in the BMW is simply hypnotic. It has so much more character and fire than the porsche engine! Don’t get me wrong, the 3.2 is also amazing, it’s just that those twin cams and 6 howling throttle-bodies are just more… So much more sexy. Have you ever heard one of those things scream it’s way thru 7000rpm?

Alfa Romeo Busso V6 for days.

901 is nice but I’d say 1987 930/66. A ROW flat six with a turbo conservatively rated @‎ 300hp and 430lbs or torque.

Don’t mean to bang on about Great Britain but. Jag Xk, Aston Martin, Austin (Big) Healey, Ford Essex, etc. Ferrari made some nice ones too, decisions!

The Chrysler Slant 6. Some day in the distant future aliens will find one in a cave. It WILL turn over and run.

The air cooled Porsche will win, but another vote for the Busso V-6. What a great engine.

A vote for Alfa Romeo Busso V6 – Beautiful design, performs well, pornographically good sound 😛
It simply makes you do stupid excuses to poke your nose under the hood and see it.

There might be “better” engines, but very few of those possess its history.

Der Yoav, I’m sorry, but what do you consider when selecting an engine as “best pre 90’s 6 cyl. engine ever?
Characteristics as Torque,….. fuel economy…….??!!, willingness to rev, top end power and do not forget sound;…… really Yoav, you have to be more specific. 🙁

Any of the 80’s F1 turbo V6 engines. Twin turbos, Tolulene based fuels, 5bar+ boost, more power than any dynomometer of the time could handle and power delivery like a switch. What’s not to like?……

BMW M20 2.3 Liter, as found in E21 and onwards. Nothing can match the induction howl at 6000rpm. An engine that lasted for decades and beyond, for nearly all 3 and 5 series BMs. A classic OHC design that pioneered the belt driven era. Bulletproof.

The Alfa Romeo Busso V6 for me. The noise is goose bump inducing & the look of the engine in the engine bay is something else…

Ok, so I have never driven a Porsche 911 or an E-Type, so I am not a great judge, but that said I think the Jaguar 4.2 is superior to the Porsche. Visually, the Jaguar 4.2 is simply the most beautiful engine ever put into a road car. Furthermore, it is (albeit with headers and not cat or muffler) by far the best sounding engine I have ever heard in person. Its true that these contribute nothing to actual performance, but in terms of “greatness,” I believe these both to be important factors. The Jaguar motor was also built for… Read more »

Maserati 250F Formula One car with the 2,5 liter 6 Cylinder engine!
8 Grand Prix Victories Total, Stirling Moss 2, Juan Manuel Fangio 6, including the German 1957 Grand Prix ahead of Hawthorne and Collins, (super famous Grand Prix, Fangios last win).
Fangio won 1 1/2 World Champion title with it, the first 2 Grand Prix of 1954 and the whole title in 1957.

BMW M88, and that’s coming from an all time alfa romeo lover. Reliability, these engines just goes on and on. High power output, even today, and with a very good rpm range makes it an engineering masterpiece.

Alfa Romeo’s Busso V6. They are incredibly fun, and the sound is truly awesome.

For me it’s the Alfa Romeo V6 designed by Giuseppe Busso. It’s reliable, looks great and makes a beautiful Sound.

I would go for either the BMW M88 just because of the history and reliability but also for the S38 for power and refinement.
The engines look good, are highly advanced and powerful even for today and can outlast the owner if properly cared for. As a bonus, they are one of the best sounding engines ever produced, ever. But if BMW would not be allowed as a choice for some reason, I’d go for a Porsche power plant because I just love engines that produce a special and unique sound.

Nissan RB series of engines; obvious choice being the RB26DETT.

Soo many good choices for 6 cylinder, obviously the obvious choice is porsche, but the M88 is right up near the top. You also have the jag 4.2. But my pick has got to be the Mercedes M198.

The 1981 alfa romeo gtv6 2.5 liters who made me a car maniac.
The 3.2 liters flat six of my 911 cabriolet (but with proper designed inox exhaust.
The 3.5 (and later 3.8) liters from bmw (M1 and M5) due to the most beautiful and racing tyme manifolds ever included to a road car.

The Porschefile in me wants to say the 911 flat 6, but I know the truth: the AMC I6. In production from 1964-2006, it was a torque monster and nearly bulletproof. There’s pretty much nowhere you wouldn’t take that engine.
