Highest output 4cyl in a production vehicle right there, but we're talking N/A.

the title of the thread is "Comparison of the best ~2 liter N/A engines ever produced"

Let me think about this I keep thinking Turbo lol!

F20C.... end of story

/thread

you think its better than the k20?

That depends on the metric, but for the most part yes

why? im not really up to date on honda jazz but i just got the impression that the honda world was liking the k more. engines are never really a concern to me...

Well the S2000 being Honda's 50th Anniversary car (who even remembers this) I would imagine they put the best engine in it lol!

I also don't think any variant of the K20A had a higher piston speed than a F20C/F22C out of the factory. That's pretty amazing if you ask me.

Another fun fact is that I watched a video of Bob Hall doing a presentation at his last ever Mazda event, he mentioned that the Honda S2000 project started originally as the S1600 and it was intented to beat the Miata in every possible spec.

yeah its a special car for sure. i dont think its hard to beat a miata in terms of objective metrics. they did that but somehow, here we are without the s2k and with a miata. my reason for question is that the kseries seems to respond to mods much better than the f20.

I think K20s are easier to come by and since they come with FWD transaxles they're popular swaps into some MR platforms, along with FWD Hondas obviously.

What can you swap an F20C into? I've never seen a swap...

Bigger crowd makes more noise.

there are k swapped miatas and s2ks. i know sometimes things are done just to be done but it raises an eyebrow

honda jazz is the honda fit in the US :thumbsup:

yeah and having a car under 2,000 lbs and 220-240++hp(some what easily) is a big deal. Everyone(still in the honda fwd game) went from b/h-series to k pretty much. Too bad they get stolen all the time and I hate being one of "those" people, especially with law enforcement. :D

I have seen a couple ae86 swaps, a datsun 1600 roadster and 510 swaps.

I guess we can call agree that the top 2.0 motor is probably from Honda motor co.

AE86 :drool: :bow:

Miata makes sense, the K20 is awesome. Are you talking about K24 swapped S2000s though? I could understand that, higher displacement and slight improvement in peak power. But that's not a 2L engine anymore.

Honda has a habit of doing one-run models...

And a 200hp/2.0L will respond to bolt-ons better than a heavily massaged 240/250hp/2.0L.

And a K series doesn't have anywhere near the lifespan of a F series when driven hard.

its a great motor but a junk chassis. i really liked mine but they are so overrated its crazy
nah. im talking k20. it seemed that once you mod things the k takes off where the f doesnt. not an expert at all though.

You sir are wrong k20 last as long as a f20c or even longer. My k20 honda took so much beating track days after track day for 5 years it never burn a single drop of oil never had no issue. Sold it to my buddy and he boosted the car to 483whp on stock internals and shit is still running like a champ. For the guys that don't know, alot of s2k owners swap the f20c out and put in a k24. It's already been proven the the k series has more potential then a f20c. The 9k redline is all achievable in all k series engine. There a reason everyone favors the k20 it has been swap in to all kinds of car and makes redicolous power and reliablity

Well, the K has much less horsepower to start with so is that really fair? lol

I can't find any K20 swaps, only K24s but I'm not looking that hard.

Out of the box, it seems like the F20 is more well suited for making power though; oil pump is OEM designed for 9000rpm, shorter stroke and longer rods, bigger valves.

I suppose one could use a K20 if you are going to build the crap out of the engine for boost since K20 parts might be easier to get or something, but that still seems like an awfully weird swap to me. The F20C is basically a better K20 lol.

:lol::lol::lol::lol::lol:

I haven't laughed this hard in a while.

:w00t:

This x1000. After driving hondas k20, the fa20 feels slow and underdeveloped.

If it's more fun to drive than the FRS... Does it matter? :bellyroll:

I agree with you, he was incorrect. The k20 is one of the most reliable engines avaliable. You can beat on that thing for 10 years, then supercharge it and beat some more. Truley inspiring engine.

Comparison of the best ~2 liter N/A engines ever produced
 

Pretty sure F20C is the best..... Factory wise.... Honda quality at its best. Imagine if FA20 redline as high as it does, we wouldn't be chit chatting like this.

Agreed. The entirety of the s2000 is absolutely amazing. The f20c is mouthwatering .. :bow:

What's upsetting about this whole thread is that you can't walk into Honda and find anything appetizing anymore...

Honestly, I always wished they would just come out with a K24 or K20 RWD Prelude

i dont know about that... i love my old hondas and they were a blast to drive in their own way. but i love the way my FRS drives too. i actually have been looking for a 90-00 civic/integra but theyre either going for too much and/or have been jacked up by their dozen previous owners lol. and i dont want to have to garage a 20yr old honda and street park my FRS just so no one jacks the damn honda :(

Or a midengine vtec delsol :(

Laugh all you want bro clearly you haven't messed with no k20 so the jokes on you dude haha. I'm telling you from my own personal experience with them, having owned 4 kswap honda. Once I got my 86 I relized how weak this thing is. No point on even trying to argue with some one that haven't tried it . Try it maybe you will get hooked for life. Tell me why if the k20 is so shit that they swap it into lotus, rx7, mr2, miata, noble, Ariel atom the list can go on and on.

People also swap ls(insert which type), 2azfe, b series, rotaries.... list goes on and on.

The answer to your questions is: Availabilty, preference and costs.

In other words: I'm a XXXX fanboy, so I want XXXX. And they are all over place for cheap

Like I said try it before you speak. Those motors you just listed don't even compare to a k series. That's why in my home town most track record are held by a k swap teggy. I'm a big fan of all kinds of cars and engine but the k is something else. Only a honda enthusiast will only understand what I'm saying

Just stop.

LOL just stop. I am not even going to try to explain WHY all of your posting is OPINION.

Sure you might have a Honda Integra, with an engine swap,in your lil home town that holds track records; but I fail to see how that is justification on why a K20 is the bee's knees like you make it out to be.

I'm sorry that working with a F2xC was out of your budget.

What did your K series make and what did you do to it?

This is a *naturally aspirated* built F2xC

quote fixed.

if you were a "true honda enthusiast" then you wouldnt be so adamant about praising the k-series against the f2x engines. you remind me of the fools back in the day that would clown on any single cams and non-vtec b/h/f-series engines just cuz they had a b16/b18c. what kind of "honda enthusiast" is that nonsense?? get that noise outta here.

the k engines are solid engines but to act like they're God's gift to gas engines is immature and a joke. you are a fanboi and not an enthusiast. get over yourself and your hometown legend stories. all of us got stories of our own. people like you are a disgrace to us old school honda guys.

Did I say anything about other honda engine bro? I played with them all and respect them all last time I checked me were talking about k series engines da fuq wrong with you. And yes I'm a big fan of the k20/24 motors the k has always made more TQ then the f20c that's why s2k owners are swapping them for k24 cause it has more usable power down low to get around the track faster.

So, so wrong.

They do it because a K24 can be had for $600, and make S2k power with a K20 head. Run it a season, and swap for a new one, because the bottom end will be done by then.

It lets you get a fatter upper-mid range, with a decreasing torque as RPMs go up, to meet power/weight requirements. If you're that low in the RPM band, you're definitely not winning.

Nobody cares about low end power on track except people who've never actually been on track.

low end power helps you have faster corner exit speed. If we comparing to only honda engines. Depends in which track your talking about also.

That is my buddy in his k24 prelude this is our home track. And you see the s2k can't even catch up to him. You see how fast his corner exit speed is compared to the s2k.
