Best 4 cylinder engine in the world

[spetz]

What do people think is the worlds best 4 cylinder engine?
Most robust, reliable, efficient etc.

I for one am voting for a 4G63 from Evolution's...

But I am expecting a lot of Honda engine's to pop up here :D

[SiR JDM]

My vote goes to the f20c just ahead of the k20a

:rolleyes: ditto...

3sgte :D

[EGB16A]

although i love my B series honda, i think the SR20 would have to be up there as one tough engine.

edit: to be more specific i ment the sr20det

[aaronng]

In terms of toughness, the 4G63. Reliability.... Hmm... probably the K20A. Power per litre, F20C. In the end, an engine is an engine. All these engines are the same with just different levels of tuning and cam profiles. Certain ones like the BMW V10 break the mould once in a while (full aluminium silicon block, NO liners) and 10 throttle bodies. Hehe.

Also, nice gems from the factory come once in a while, like the B18C5.

ohh man what a question..

N/A or Forced induction ?

we talking completely bone-stock from the factory or highly tuned ?

and by 'best' what do you mean ?? most HP, Most Torque, most innovative, highest HP/Litre ratio.. best build quality ?

anyway..

For N/A 4-cyl I dont think you can go past the B16A (Gen 1) when you consider that it was implemented into 'cheap' production cars WAAAYY back in 1989 !! over 100HP per Litre plus variable valve timing and electronic lift controll on a DOHC 16v all-alloy engine that revs to 8,000RPM all day happilly.. not to mention OBD1 and PGMFI being very advanced systems for their time.

For 21st century HONDAs I'd agree that the F20C motor is very tasty and arguably the benchmark for the K20.. the K20 which is heading towards optimal efficiency for N/A internal combustion engines in terms of design however to be honest I fear that honda has aimed the K-series of motors to be almost too-generic and mindfull of cost compared to the extravagant packages previously on offer such as the B16B. F20C, H22A and C30As.. if you know what I mean..

Honda has always prided themselves firtsly and foremostly as an engine manufacturer and with noted exceptions (City Turbo and JGTCC NSX-T), prides itself also on building strong and efficient Naturally Aspirated engines. I'd be surprised if there was a better N/A engine builder form the factory, however I admit I may be naive to certain other Japanese manufacturers offerings and do not ignore european (especially German) 4-cyllinder offerings from Porche, Audi, BMW.. then over to italy with some hot Alpha's and even Fiats.

My other favorite N/A 4-cyl engine that I have experienced is Toyota's 4AG (Ithink) 20V with the wierd sortov 'VTEC' etc. but once again I admit I am naive to other builder's engine codes.

LMFAO off topic there's a "V-Tech" infomercial on TV as I am typing this.. "you must have heard of V-Tech" was the opening line LMFAO... DONT THEY KNOW THERE'S NO "H" ;P

[EGB16A]

Naturally asperated engine award would have to go to honda wouldn't it? Just the simple fact that they produce 100hp/L is very impressive! If holden were to do this, they would have 570hp engines in all their hsv range! LOL
they're 6cyl VN commo would produce 380 hp...... YEAH RIGHT!!

[V8_Hero]

half an LS2
.
..
...j/k
seriously h22a cos they are better than the b series engines

[lloydbanks]

d16y4... lol. They don't go fast, but they take a lickin' & keep on tickin'...

[Usual Suspect]

NA has to go to the b16a, follwed closesly by h22a, k20a and f20c (in no particualr order)

FI id give it to the 4G63.

[Captiva_Blue]

H22A, F20C.. if we're talking NA, also the 2L in the Renaultsport Clio 182

Forced induction, the 4G63 has to have it..

[JDM.Power]

ej20 Sti engine = forced
f20c s2k motor = n/a

[raff]

F20c

[PhatSol]

Has to be the F20C :D

After that 4G63, SR20, B18C, K20A, etc....

[Boostzor]

Nobody has mentioned the Ca-18det yet. Its 2/3s of an rb26 mmmm solid lifters. Not ultra grunty but in a light car.......

[IRI]

F20c!!!!!!!!!!:D

[wlee2]

B18C7!!!!!.. ^_^.. what i just wanted to be different =P...

[V8_Hero]

sr16vvl n1

[Steer^Gimic]

why dont you boys take a trip back in time and look at what made a b16 or a f20c possible
Lotus 1.6 Twin Cam
http://sportcompactcarweb.com/features/0411scc_lotus10_z.jpg

and the Cosworth RS500 donk
http://img19.photobucket.com/albums/v56/rs500/100_0701.jpg

im sure that despite the fact that both of these engines are more then 10years older then your b16a, your guranteed to be surprised by the results!

[mini_s2000]

steer^gimic knows his shit... i suggest we end this thread on that note!

[Usual Suspect]

lol i doubt that last engine is production based lol, but the old cosworth engine is a very good one indeed.

[garett]

f20c


as for old school 2l alfa twin cam

the NA sr20 and ca18 are pretty suck

[CHU85]

i second the motion for the cosworth!!!!
Very tough engines from factory.

[T-onedc2]

FYI VT3C and others interested:

I owned an AE93 Corolla SX in which I had a conversion completed,
The Toyota 20v is the last of the 4AGE 1600 family with 5 valves per cylinder and 4 throttle intake, they are actually VVT engines, meaning the the inlet camshaft has variable timing only. It is programmed to activate initially at about 3500rpm with adjustment also made about 5000rpm and also 7900rpm, on the way to 8200rpm cutout, and believe me the last 3000rpm are very noticable, however an aftermarket tuned properly is said to flatten out the bumpy torque curve and give up to something like 15fwkw increase i''ve heard. Known as the "siver top" 160hp (factory claim) it's a great little engine with great response and surprising low down torque helped by a close ratio 5 speed. The later "black top" was the same with revised ecu and I think VVT-i giving the ability to vary timing anywhere depending on throttle position, lightweight cams & valves, stonger valve springs and made another 10hp to about 170hp (factory claim) plus a 6 speed box.

Here's some pics :)

[aaronng]

I've saved your first pic of your engine bay. She's a beaut!

[zco]

i dont know what the engine is called.. but its from the subaru impreza22b

[ginganggooly]

nice, i didn't know the silvertops came from the factory with quads... very nice

[samsider]

Sr20det

[furiou5]

We'll just to chuck something else in the mix, how about the suzuki Hyabusa(bike) motors arn't they 1.3l making 130kws

i swear i've read that somewhere

[sivic]

if you after efficiency - all turbos out the window.
its a bit of a random question though cos if you are looking for the best engine design you have to look at NA's and the ability to produce power without FI.
all the hero turbo 4 cylinders are crap in their NA form

but in any case
FI - 4G63T
NA - F20C / K20

although there are toyota and nissan engine which look just as good on paper, in practice they dont quite make it - crap power bands / gear ratios and reliablity
