Most powerful NA 4cyl?

iron duke

because it'll keep going 700,000 miles after the other faggots blew their engines up

That's not an offy 4 banger.

Pontiac SD4 sang to the tune of some 400hp- But shit's rare as fuck yo.

Cosworth yb with the turbo removed?
Cosworth bda?
The beams is nice but really the f20c is a better engine.
Bmw s14 maybe?
Pretty much pick anything that was used in motorsport op.

>>16248688
the biggest one around.
i.e a porsche 3.0 will make the same peak as a F20c but have a shitload more area under the curve

>>16248688
F22C is your best bet, better then the F20c and can be upped to 9k readline

>>16248759
The f22 was made for fat americans with sub-optimal fuel who were afraid of anything that revved mildly high cuz muh v8.
Even the f20 you guys got was a de-tuned donkey show.

>>16248709
What

>>16248688
I'm a degenerate Toyota fag and know damn well you get better power out of the Honda 4 bangers. BEAMS is superior driving experience

>>16248764
Sorry mate to trigger ya, but I have a itb f20c in my S.

All I'm saying is there is no replacement for displacement, also probably shouldn't assume I'm a Americunt

100% true, only low test betas disagree

>>16248755
I came in here to mention the porsche 3l 4banger from the 968

Alfa Twincam
Mercedes M111
Opel 20XE

>>16248774
Yep agreed.
F2xC can also easily be upped to 2.4 with only a 106mm crank change, so its probably the best bang for buck, compared to other 4bangers (maybe except for the K24, on occasion)

Also why put throttle bodies on an f20, you probably paid 4k+ for the bodies, ecu, cams etc for about 10 hp, You're either retarded or a bullshit artist.

The GM Quad 4 was heavily inspired by the Offy

>>16248766
>What
Offenhauser was an American company known for their 4 cylinder Formula 1 racing engines. The engines were capable of taking as much booth as you wanted due to them not having a separate cylinder head, meaning no head gasket to blow.

>as much booth

Well the Mitsubishi Astron was pretty good. Not the most reliable, but older carbonated versions were used in everything from pickup trucks, forklifts, and even outboard motors.

They were all around 2.3-2.6 liters of displacement, tarbo, fuel injected, and carbonated, chain driven, single cam, 2 valves per cylinder.
There was even a diesel version of the Astron engine called the 4D
Hyundai used them, Ford used them, Dodge used them.

It's an enduro/demo car, doesn't need to be pretty, just needs to work.

Expandable foam offers a little extra crash protection for the fuse box and degauss bottle

Seat belts work great to hold the rad in somewhat of a place once the front end gets smashed

Garden hose works great to route battery cables in and keep them from getting pinched or cut

All thread to hold the hood shut

Definitely not pic related
It only makes 160hp at 6000rpm
F20c is peaky trash

>>16249415
Reliability is not what OP asked about. If reliability were the measuring stick, the best 4 cylinder would be GM's Iron Duke.

>>16249391
No. Way too peaky and doesn't make enough torque.

k20 makes good power and has a decent rpm

FJ20/FJ24 literally any other answer is plain wrong.

>>16250154
But if you get the ones that make great power, like the K20A2, they're very peaky and don't make enough torque. Horsepower is not the only measuring stick.

I got a H22 ek and it makes 154 lb-ft of torque. Plenty around town for a car that light. It also revs to 8k.

Pretty much any 4 cyl that's stroked will get you what you want. A beefy torque curve that revs decently.

I'd reccomend:
K24A2
H22
SR20

I've personally never ridden in a car, or driven a car with a beams motor, but from looking at the specifications, I have a feeling it'd be a fun motor.

>>16250143
180Kw stock output anon , where did you get 160hp from?

>>16253371
180kw at over nine thousand
at 6000rpm its only putting down 160hp

>>16253373
Why do you care about the power on a low RPM for a high RPM engine?

>>16248774
bore and stroke
forced induction

>but muh equivalent engine with more cc/ci's
but you REPLACE the displacement upgrade with a different modification

>>16253394
>6000rpm
>low rpm
for way of reference a 13b-msp makes 170hp at 6000rpm and is a 1.3l :^)

>>16253405
It also makes 231hp @8200rpm, also the f20c VTEC kicks in at 6250rpm so it gains much power just a few rpm higher.

>Not mentioning the 4G63

Clearly never driven a stripped civic with it. More torque and you get diminuishing returns.

That's not how it works. Ricer logic does not work in the real world. Even stripped, the car still has the same amount of torque as before.

>>16254425
found the retard

>>16249184
they haven't done their final tune yet, but i don't get why their numbers are so low... maybe wrong length intake runners

there should be an official /o/ checklist to gauge if your engine is retarded or not -

1.) does it have more than one cam?
2.) interference?
3a.) variable timing?
3b.) variable timing on multiple cams?
4.) more than 1 intake/exhaust valve?
5.) block and head made from different metals?
6.) thrust bearing not in center?

answering yes to any of these means your engine is garbage

>>16258061

Why in hell would anyone dick around with a pos lima engine just tog get a better head from another manufacturer onto it? The lima is shit, total shit there'sa reason you're looking to other brands for a better head. So even knowing the lima is a piece of garbage, why wouldn't you just use the whole volvo engine how cuckold do you have to be to choose the worst option of combining the two?
