K20C1 Engine Thread

[NorthernEX-T]

Lets get an engine thread going.

What do we see new? Intake manifold/air intake, valve cover.., anything else?

Somebody mentioned a possible crossfire firing order? Is that even a thing on 4 cyls?

I'm surprised no one has done a technical detailed review of the K20C1. Not even Honda has any info about it. At least with the old Integra Type R B18C5 engine, Honda published a bunch of technical differences between the base and the Type R engine.

Wonder if it'll have forged internals, similar to the F20/F22.

Is there an upper strut bar? I only see the brackets in black

It has aluminum pistons, and forged rods and crank I read somewhere on one of the older fk2 forums

@09CivicSiBrian now we how that 400whp is doable I'd say, coming from Honda! 450hp!!

Forged rods and crank most all engines have that now. I want to see cut aways etc. does it have good oiling, does it have bearings on both cams, full floating pistons, good rings for reduced oil consumption, is the air filter large and thick etc etc etc. Honda engines are usually pretty good except for oil consumption issues that I have experienced.

Rigidity/stiffness way up over last chassis... I'm guessing the use of adhesives > strut tower bar.

I just noticed the press release claims "i-vtec"... I'm guessing vtc on both intake and exhaust side, but in terms of variable lift, is it still just exhaust side like the old i-vtec in my ep3? Please correct me if I have no idea what's going on.. I just remember old school vtec(variable lift on both intake and exhaust side?) was wild once it hits, but that sure isn't the case from what I've experienced from I-vtec.

Aluminum pistons is what I was getting at

Look man, this car right here is like the Mona Lisa of the car world. Honda built this bad-boy from ground up. We talkin forged pistons, bigger turbo, new rise, new crankshaft.

The voted on this car engages at lower rpm to reduce turbo lag.

I really hope this car has no egr system

Everything has aluminum Pistons too lol.

Pfff no.

 

[Evo]

Pfff no.

Anything I want buy does! Quite a few of my past cars had forged Pistons, the Evolution had them in both 4G63 and 4B11

 

[NorthernEX-T]

Eww 4g63 makes me
